The field de_name_len is the number of bytes +* actually required for the name (no null terminator). The field de_rec_len +* is the number of bytes allocated to the dirent. The offset of the next +* dirent in the block is (dirent + dirent->de_rec_len). When a dirent is +* deleted, the preceding dirent inherits its allocated space, ie +* prev->de_rec_len += deleted->de_rec_len. Since the next dirent is obtained +* by adding de_rec_len to the current dirent, this essentially causes the +* deleted dirent to get jumped over when iterating through all the dirents. +* +* When deleting the first dirent in a block, there is no previous dirent so +* the field de_ino is set to zero to designate it as deleted. When allocating +* a dirent, gfs2_dirent_alloc iterates through the dirents in a block. If the +* first dirent has (de_ino == 0) and de_rec_len is large enough, this first +* dirent is allocated. Otherwise it must go through all the 'used' dirents +* searching for one in which the amount of total space minus the amount of +* used space will provide enough space for the new dirent. +* +* There are two types of blocks in which dirents reside. In a stuffed dinode, +* the dirents begin at offset sizeof(struct gfs2_dinode) from the beginning of +* the block. In leaves, they begin at offset sizeof(struct gfs2_leaf) from the +* beginning of the leaf block. The dirents reside in leaves when +* +* dip->i_di.di_flags & GFS2_DIF_EXHASH is true +* +* Otherwise, the dirents are "linear", within a single stuffed dinode block. +* +* When the dirents are in leaves, the actual contents of the directory file are +* used as an array of 64-bit block pointers pointing to the leaf blocks. The +* dirents are NOT in the directory file itself. There can be more than one block +* pointer in the array that points to the same leaf. In fact, when a directory +* is first converted from linear to exhash, all of the pointers point to the +* same leaf. +* +* When a leaf is completely full, the size of the hash table can be +* doubled unless it is already at the maximum size which is hard coded into +* GFS2_DIR_MAX_DEPTH. After that, leaves are chained together in a linked list, +* but never before the maximum hash table size has been reached. +*/ + +#include +#include +#include +#include +#include +#include +#include + +#include "gfs2.h" +#include "dir.h" +#include "glock.h" +#include "inode.h" +#include "jdata.h" +#include "meta_io.h" +#include "quota.h" +#include "rgrp.h" +#include "trans.h" + +#define IS_LEAF 1 /* Hashed (leaf) directory */ +#define IS_DINODE 2 /* Linear (stuffed dinode block) directory */ + +#if 1 +#define gfs2_disk_hash2offset(h) (((uint64_t)(h)) >> 1) +#define gfs2_dir_offset2hash(p) ((uint32_t)(((uint64_t)(p)) << 1)) +#else +#define gfs2_disk_hash2offset(h) (((uint64_t)(h))) +#define gfs2_dir_offset2hash(p) ((uint32_t)(((uint64_t)(p)))) +#endif + +typedef int (*leaf_call_t) (struct gfs2_inode *dip, + uint32_t index, uint32_t len, uint64_t leaf_no, + void *data); + +/** + * int gfs2_filecmp - Compare two filenames + * @file1: The first filename + * @file2: The second filename + * @len_of_file2: The length of the second file + * + * This routine compares two filenames and returns 1 if they are equal. + * + * Returns: 1 if the files are the same, otherwise 0. + */ + +int gfs2_filecmp(struct qstr *file1, char *file2, int len_of_file2) +{ + if (file1->len != len_of_file2) + return 0; + if (memcmp(file1->name, file2, file1->len)) + return 0; + return 1; +} + +/** + * dirent_first - Return the first dirent + * @dip: the directory + * @bh: The buffer + * @dent: Pointer to list of dirents + * + * return first dirent whether bh points to leaf or stuffed dinode + * + * Returns: IS_LEAF, IS_DINODE, or -errno + */ + +static int dirent_first(struct gfs2_inode *dip, struct buffer_head *bh, + struct gfs2_dirent **dent) +{ + struct gfs2_meta_header *h = (struct gfs2_meta_header *)bh->b_data; + + if (be16_to_cpu(h->mh_type) == GFS2_METATYPE_LF) { + if (gfs2_meta_check(dip->i_sbd, bh)) + return -EIO; + *dent = (struct gfs2_dirent *)(bh->b_data + + sizeof(struct gfs2_leaf)); + return IS_LEAF; + } else { + if (gfs2_metatype_check(dip->i_sbd, bh, GFS2_METATYPE_DI)) + return -EIO; + *dent = (struct gfs2_dirent *)(bh->b_data + + sizeof(struct gfs2_dinode)); + return IS_DINODE; + } +} + +/** + * dirent_next - Next dirent + * @dip: the directory + * @bh: The buffer + * @dent: Pointer to list of dirents + * + * Returns: 0 on success, error code otherwise + */ + +static int dirent_next(struct gfs2_inode *dip, struct buffer_head *bh, + struct gfs2_dirent **dent) +{ + struct gfs2_dirent *tmp, *cur; + char *bh_end; + uint32_t cur_rec_len; + + cur = *dent; + bh_end = bh->b_data + bh->b_size; + cur_rec_len = be32_to_cpu(cur->de_rec_len); + + if ((char *)cur + cur_rec_len >= bh_end) { + if ((char *)cur + cur_rec_len > bh_end) { + gfs2_consist_inode(dip); + return -EIO; + } + return -ENOENT; + } + + tmp = (struct gfs2_dirent *)((char *)cur + cur_rec_len); + + if ((char *)tmp + be32_to_cpu(tmp->de_rec_len) > bh_end) { + gfs2_consist_inode(dip); + return -EIO; + } + /* Only the first dent could ever have de_inum.no_addr == 0 */ + if (!tmp->de_inum.no_addr) { + gfs2_consist_inode(dip); + return -EIO; + } + + *dent = tmp; + + return 0; +} + +/** + * dirent_del - Delete a dirent + * @dip: The GFS2 inode + * @bh: The buffer + * @prev: The previous dirent + * @cur: The current dirent + * + */ + +static void dirent_del(struct gfs2_inode *dip, struct buffer_head *bh, + struct gfs2_dirent *prev, struct gfs2_dirent *cur) +{ + uint32_t cur_rec_len, prev_rec_len; + + if (!cur->de_inum.no_addr) { + gfs2_consist_inode(dip); + return; + } + + gfs2_trans_add_bh(dip->i_gl, bh); + + /* If there is no prev entry, this is the first entry in the block. + The de_rec_len is already as big as it needs to be.

Fixes for the various bugs will be forthcoming shortly. This patch removes the special data format which has been used up till now for journaled data files. Directories still retain the old format so that they will remain on disk compatible with earlier releases. As a result you can now do the following with journaled data files: 1) mmap them 2) export them over NFS 3) convert to/from normal files whenever you want to (the zero length restriction is gone) In addition the level at which GFS' locking is done has changed for all files (since they all now use the page cache) such that the locking is done at the page cache level rather than the level of the fs operations. This should mean that things like loopback mounts and other things which touch the page cache directly should now work. Current known issues: 1. There is a lock mode inversion problem related to the resource group hold function which needs to be resolved. 2. Any significant amount of I/O causes an oops with an offset of hex 320 (NULL pointer dereference) which appears to be related to a journaled data buffer appearing on a list where it shouldn't be. 3. Direct I/O writes are disabled for the time being (will reappear later) 4. There is probably a deadlock between the page lock and GFS' locks under certain combinations of mmap and fs operation I/O. 5. Issue relating to ref counting on internally used inodes causes a hang on umount (discovered before this patch, and not fixed by it) 6. One part of the directory metadata is different from GFS1 and will need to be resolved before next release.

The DIV_RU macro is renamed DIV_ROUND_UP and and moved to kernel.h The other macros are gone from gfs2.h as (although not requested by Pekka Enberg) are a number of included header file which are now included individually. The inode number comparison function is now an inline function. The DT2IF and IF2DT may be addressed in a future patch.

Also some other tidy ups are included: - We use GFS2's hash function for dentries (see ops_dentry.c) so that we don't have to keep recalculating the hash values. - A lot of common code is eliminated between the various directory lookup routines. - Better error checking on directory lookup (previously different routines checked for different errors) - The leaf split operation has a couple of redundant operations removed from it, so it should be faster. There is still further scope for further clean ups in the directory code, and readdir in particular could do with slimming down a bit.

We don't need the inherited flags since this action can be implied by setting the flags on directories where they wouldn't otherwise make sense. It reduces the number of extra flags by two. Also updated the list of flags to take account of one extra ext2/3 flag.

There is a known bug in gfs2_ea_get() which is believed to be independant of this patch. Further patches will follow once that bug is fixed in order to make GFS2 use as much of the generic eattr infrastructure as possible.

It removes all limits (other than memory for inodes, as per every other filesystem) on numbers of these which we can support on GFS2. It also means that (like other fs) its the responsibility of the last process to close the file to deallocate the storage, rather than the person who did the unlinking. Note that with GFS2, those two events might take place on different nodes. Also there are a number of other changes: o We use the Linux inode subsystem as it was intended to be used, wrt allocating GFS2 inodes o The Linux inode cache is now the point which we use for local enforcement of only holding one copy of the inode in core at once (previous to this we used the glock layer). o We no longer use the unlinked "special" file. We just ignore it completely. This makes unlinking more efficient. o We now use the 4th block allocation state. The previously unused state is used to track unlinked but still open inodes. o gfs2_inoded is no longer needed o Several fields are now no longer needed (and removed) from the in core struct gfs2_inode o Several fields are no longer needed (and removed) from the in core superblock There are a number of future possible optimisations and clean ups which have been made possible by this patch.

Its backward compatible with the current code since it doesn't really matter what the generation number is to start with, and indeed since its set to zero, due to it being taken from padding in both the inode and rgrp header, it should be fine. The eventual plan is to use this rather than no_formal_ino in the NFS filehandles. At that point no_formal_ino will be unused. At the same time we also add a releasepages call back to the "normal" address space for gfs2 inodes. Also I've removed a one-linrer function thats not required any more.

Some of these prevent oopses when the SG_SCATTER_SZ or scatter_elem_sz are set to inappropriate values. The scatter_elem_sz has been tested up to 4 MB which should make the largest data transfer with one SCSI command, 32 MB less one block, achievable with a relatively small number of elements in the scatter gather list. ChangeLog: - add scatter_elem_sz boot time parameter and sysfs module parameter that is initialized to SG_SCATTER_SZ - the driver will then adjust scatter_elem_sz to be the max(given(scatter_elem_sz), PAGE_SIZE) It will also round it up, if necessary, to be a power of two - clean up sg.h header, correct bad urls and some statements that are no longer valid - make the def_reserved_size sysfs module attribute writable Signed-off-by: Douglas Gilbert Signed-off-by: James Bottomley --- drivers/scsi/sg.c | 53 +++++++++++++++++++++++++++++++++++------------ include/scsi/sg.h | 61 +++++++++++++++++++------------------------------------ 2 files changed, 61 insertions(+), 53 deletions(-) (limited to 'include') diff --git a/drivers/scsi/sg.c b/drivers/scsi/sg.c index 34f9343ed0af..3f8b93188567 100644 --- a/drivers/scsi/sg.c +++ b/drivers/scsi/sg.c @@ -60,7 +60,7 @@ static int sg_version_num = 30534; /* 2 digits for each component */ #ifdef CONFIG_SCSI_PROC_FS #include -static char *sg_version_date = "20060818"; +static char *sg_version_date = "20060920"; static int sg_proc_init(void); static void sg_proc_cleanup(void); @@ -94,6 +94,9 @@ int sg_big_buff = SG_DEF_RESERVED_SIZE; static int def_reserved_size = -1; /* picks up init parameter */ static int sg_allow_dio = SG_ALLOW_DIO_DEF; +static int scatter_elem_sz = SG_SCATTER_SZ; +static int scatter_elem_sz_prev = SG_SCATTER_SZ; + #define SG_SECTOR_SZ 512 #define SG_SECTOR_MSK (SG_SECTOR_SZ - 1) @@ -1537,11 +1540,9 @@ sg_remove(struct class_device *cl_dev, struct class_interface *cl_intf) msleep(10); /* dirty detach so delay device destruction */ } -/* Set 'perm' (4th argument) to 0 to disable module_param's definition - * of sysfs parameters (which module_param doesn't yet support). - * Sysfs parameters defined explicitly below. - */ -module_param_named(def_reserved_size, def_reserved_size, int, S_IRUGO); +module_param_named(scatter_elem_sz, scatter_elem_sz, int, S_IRUGO | S_IWUSR); +module_param_named(def_reserved_size, def_reserved_size, int, + S_IRUGO | S_IWUSR); module_param_named(allow_dio, sg_allow_dio, int, S_IRUGO | S_IWUSR); MODULE_AUTHOR("Douglas Gilbert"); @@ -1550,6 +1551,8 @@ MODULE_LICENSE("GPL"); MODULE_VERSION(SG_VERSION_STR); MODULE_ALIAS_CHARDEV_MAJOR(SCSI_GENERIC_MAJOR); +MODULE_PARM_DESC(scatter_elem_sz, "scatter gather element " + "size (default: max(SG_SCATTER_SZ, PAGE_SIZE))"); MODULE_PARM_DESC(def_reserved_size, "size of buffer reserved for each fd"); MODULE_PARM_DESC(allow_dio, "allow direct I/O (default: 0 (disallow))"); @@ -1558,8 +1561,14 @@ init_sg(void) { int rc; + if (scatter_elem_sz < PAGE_SIZE) { + scatter_elem_sz = PAGE_SIZE; + scatter_elem_sz_prev = scatter_elem_sz; + } if (def_reserved_size >= 0) sg_big_buff = def_reserved_size; + else + def_reserved_size = sg_big_buff; rc = register_chrdev_region(MKDEV(SCSI_GENERIC_MAJOR, 0), SG_MAX_DEVS, "sg"); @@ -1842,15 +1851,30 @@ sg_build_indirect(Sg_scatter_hold * schp, Sg_fd * sfp, int buff_size) if (mx_sc_elems < 0) return mx_sc_elems; /* most likely -ENOMEM */ + num = scatter_elem_sz; + if (unlikely(num != scatter_elem_sz_prev)) { + if (num < PAGE_SIZE) { + scatter_elem_sz = PAGE_SIZE; + scatter_elem_sz_prev = PAGE_SIZE; + } else + scatter_elem_sz_prev = num; + } for (k = 0, sg = schp->buffer, rem_sz = blk_size; (rem_sz > 0) && (k < mx_sc_elems); ++k, rem_sz -= ret_sz, ++sg) { - num = (rem_sz > SG_SCATTER_SZ) ?

No one calls xmon() anymore, debugger() is preferable, so we don't need the prototype. And similarly no one calls xmon_printf(). Also update the include guards on xmon.h to match the standard format, add copyright and license, and add comments to #endifs. Built for pseries_defconfig and pmac32_defconfig.

No one does this obviously as xmon rocks, but it should really work as documented. While fixing that it struck me that we could move the xmon param handling into xmon.c, and also consolidate the xmon_init()/do_early_xmon logic into xmon_setup(). This means xmon=early drops into xmon a little earlier on 32-bit, but it seems to work just fine. Tested on PSERIES and CLASSIC32.

In addition, the following changes have been made: o removed typedefs o uint -> u32 conversions o removed following defines: QE_SIZEOF_BD, BD_BUFFER_ARG, BD_BUFFER_CLEAR, BD_BUFFER, BD_STATUS_AND_LENGTH_SET, BD_STATUS_AND_LENGTH, and BD_BUFFER_SET because they hid sizeof/in_be32/out_be32 operations from the reader. o fixed qe_snums_init() serial num assignment to use a const array o made CONFIG_UCC_FAST select UCC_SLOW o reduced NR_QE_IC_INTS from 128 to 64 o remove _IO_BASE, etc. defines (not used) o removed irrelevant comments, added others to resemble removed BD_ defines o realigned struct definitions in headers o various other style fixes including things like pinMask -> pin_mask o fixed a ton of whitespace issues o marked ioregs as __be32/__be16 o removed platform_device code and redundant get_qe_base() o removed redundant comments o added cpu_relax() to qe_reset o uncasted all get_property() assignments o eliminated unneeded casts o eliminated immrbar_phys_to_virt (not used) Signed-off-by: Li Yang Signed-off-by: Shlomi Gridish Signed-off-by: Kim Phillips Signed-off-by: Paul Mackerras --- arch/powerpc/Kconfig | 12 + arch/powerpc/sysdev/Makefile | 1 + arch/powerpc/sysdev/qe_lib/Kconfig | 30 ++ arch/powerpc/sysdev/qe_lib/Makefile | 8 + arch/powerpc/sysdev/qe_lib/qe.c | 353 +++++++++++++++++++++ arch/powerpc/sysdev/qe_lib/qe_ic.c | 555 ++++++++++++++++++++++++++++++++++ arch/powerpc/sysdev/qe_lib/qe_ic.h | 106 +++++++ arch/powerpc/sysdev/qe_lib/qe_io.c | 226 ++++++++++++++ arch/powerpc/sysdev/qe_lib/ucc.c | 251 +++++++++++++++ arch/powerpc/sysdev/qe_lib/ucc_fast.c | 396 ++++++++++++++++++++++++ arch/powerpc/sysdev/qe_lib/ucc_slow.c | 404 +++++++++++++++++++++++++ include/asm-powerpc/immap_qe.h | 477 +++++++++++++++++++++++++++++ include/asm-powerpc/qe.h | 457 ++++++++++++++++++++++++++++ include/asm-powerpc/qe_ic.h | 64 ++++ include/asm-powerpc/ucc.h | 84 +++++ include/asm-powerpc/ucc_fast.h | 243 +++++++++++++++ include/asm-powerpc/ucc_slow.h | 289 ++++++++++++++++++ include/linux/fsl_devices.h | 65 +++- 18 files changed, 4007 insertions(+), 14 deletions(-) create mode 100644 arch/powerpc/sysdev/qe_lib/Kconfig create mode 100644 arch/powerpc/sysdev/qe_lib/Makefile create mode 100644 arch/powerpc/sysdev/qe_lib/qe.c create mode 100644 arch/powerpc/sysdev/qe_lib/qe_ic.c create mode 100644 arch/powerpc/sysdev/qe_lib/qe_ic.h create mode 100644 arch/powerpc/sysdev/qe_lib/qe_io.c create mode 100644 arch/powerpc/sysdev/qe_lib/ucc.c create mode 100644 arch/powerpc/sysdev/qe_lib/ucc_fast.c create mode 100644 arch/powerpc/sysdev/qe_lib/ucc_slow.c create mode 100644 include/asm-powerpc/immap_qe.h create mode 100644 include/asm-powerpc/qe.h create mode 100644 include/asm-powerpc/qe_ic.h create mode 100644 include/asm-powerpc/ucc.h create mode 100644 include/asm-powerpc/ucc_fast.h create mode 100644 include/asm-powerpc/ucc_slow.h (limited to 'include') diff --git a/arch/powerpc/Kconfig b/arch/powerpc/Kconfig index b29adaa97348..2587468eec43 100644 --- a/arch/powerpc/Kconfig +++ b/arch/powerpc/Kconfig @@ -351,6 +351,16 @@ config APUS . endchoice +config QUICC_ENGINE + bool + depends on PPC_MPC836x || PPC_MPC832x + default y + help + The QUICC Engine (QE) is a new generation of communications + coprocessors on Freescale embedded CPUs (akin to CPM in older chips). + Selecting this option means that you wish to build a kernel + for a machine with a QE coprocessor. + config PPC_PSERIES depends on PPC_MULTIPLATFORM && PPC64 bool "IBM pSeries & new (POWER5-based) iSeries" @@ -1059,6 +1069,8 @@ source "fs/Kconfig" #

However, nested interrupts are better for latency. This code uses the EIEM register to simulate level interrupts and thus achieve nesting.

This means we need to be a bit careful about arrays of size RPCSVC_MAXPAGES. struct svc_rqst contains two such arrays. However the there are never more that RPCSVC_MAXPAGES pages in the two arrays together, so only one array is needed. The two arrays are for the pages holding the request, and the pages holding the reply. Instead of two arrays, we can simply keep an index into where the first reply page is. This patch also removes a number of small inline functions that probably server to obscure what is going on rather than clarify it, and opencode the needed functionality. Also remove the 'rq_restailpage' variable as it is *always* 0. i.e. if the response 'xdr' structure has a non-empty tail it is always in the same pages as the head. check counters are initilised and incr properly check for consistant usage of ++ etc maybe extra some inlines for common approach general review Signed-off-by: Neil Brown Cc: Magnus Maatta Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- fs/nfsd/nfs2acl.c | 2 +- fs/nfsd/nfs3acl.c | 2 +- fs/nfsd/nfs3xdr.c | 23 +++++-------- fs/nfsd/nfs4xdr.c | 27 ++++++++------- fs/nfsd/nfsxdr.c | 13 +++----- fs/nfsd/vfs.c | 16 +++++---- include/linux/sunrpc/svc.h | 69 ++++++--------------------------------- net/sunrpc/auth_gss/svcauth_gss.c | 4 +-- net/sunrpc/svc.c | 21 ++++-------- net/sunrpc/svcsock.c | 41 +++++++++++------------ 10 files changed, 77 insertions(+), 141 deletions(-) (limited to 'include') diff --git a/fs/nfsd/nfs2acl.c b/fs/nfsd/nfs2acl.c index fe56b38364cc..71108da2e54e 100644 --- a/fs/nfsd/nfs2acl.c +++ b/fs/nfsd/nfs2acl.c @@ -241,7 +241,7 @@ static int nfsaclsvc_encode_getaclres(struct svc_rqst *rqstp, u32 *p, rqstp->rq_res.page_len = w;

As we plan to increase RPCSVC_MAXPAGES from 8 upto 256, we can no longer allocate an array of this size on the stack. So we allocate it in 'struct svc_rqst'. However svc_rqst contains (indirectly) an array of the same type and size (actually several, but they are in a union). So rather than waste space, we move those arrays out of the separately allocated union and into svc_rqst to share with the kvec moved out of svc_tcp_recvfrom (various arrays are used at different times, so there is no conflict).

Also, make some of the apparently arbitrary sizing constants clearer. The biggest change here involves replacing NFSSVC_MAXBLKSIZE by a function of the rqstp. This allows it to be different for different protocols (udp/tcp) and also allows it to depend on the servers declared sv_bufsiz. Note that we don't actually increase sv_bufsz for nfs yet. That comes next.

This helps workloads using AUTH_SYS authentication over TCP. Testing was on a 4 CPU 4 NIC Altix using 4 IRIX clients, each with 16 synthetic client threads simulating an rsync (i.e. recursive directory listing) workload reading from an i386 RH9 install image (161480 regular files in 10841 directories) on the server. That tree is small enough to fill in the server's RAM so no disk traffic was involved. This setup gives a sustained call rate in excess of 60000 calls/sec before being CPU-bound on the server. Profiling showed strcmp(), called from ip_map_match(), was taking 4.8% of each CPU, and ip_map_lookup() was taking 2.9%. This patch drops both contribution into the profile noise. Note that the above result overstates this value of this patch for most workloads. The synthetic clients are all using separate IP addresses, so there are 64 entries in the ip_map cache hash. Because the kernel measured contained the bug fixed in commit commit 1f1e030bf75774b6a283518e1534d598e14147d4 and was running on 64bit little-endian machine, probably all of those 64 entries were on a single chain, thus increasing the cost of ip_map_lookup(). With a modern kernel you would need more clients to see the same amount of performance improvement. This patch has helped to scale knfsd to handle a deployment with 2000 NFS clients.

With this patch applied, all nlm_hosts from the same address will share the same nsm_handle. A future patch will add sharing by name. Note: this patch changes h_name so that it is no longer guaranteed to be an IP address of the host. When the host represents an NFS server, h_name will be the name passed in the mount call. When the host represents a client, h_name will be the name presented in the lock request received from the client.

To make it a bit clear what is happening: nlmclent_prepare_reclaim and nlmclnt_finish_reclaim get open-coded into 'reclaimer' The result is tidied up. Then some of that functionality is moved out into nlm_host_rebooted (which calls nlmclnt_recovery which starts a thread which runs reclaimer). Also host_rebooted now finds an nsm_handle rather than a host, then then iterates over all hosts and deals with each host that shares that nsm_handle.

However, this means the cookies are not unique, so that when the client's GRANTED_RES message comes back, we cannot simply match it based on the cookie, but have to use the client's IP address in addition. Which breaks when you have a multi-homed NFS client. The X/Open spec explicitly mentions that clients should not expect the same cookie; so one may hope that any clients that were broken in 1996 have either been fixed or rendered obsolete.

Biederman" Date: Wed, 4 Oct 2006 02:16:27 -0700 Subject: [PATCH] genirq: irq: convert the move_irq flag from a 32bit word to a single bit The primary aim of this patchset is to remove maintenances problems caused by the irq infrastructure. The two big issues I address are an artificially small cap on the number of irqs, and that MSI assumes vector == irq. My primary focus is on x86_64 but I have touched other architectures where necessary to keep them from breaking. - To increase the number of irqs I modify the code to look at the (cpu, vector) pair instead of just looking at the vector. With a large number of irqs available systems with a large irq count no longer need to compress their irq numbers to fit. Removing a lot of brittle special cases. For acpi guys the result is that irq == gsi. - Addressing the fact that MSI assumes irq == vector takes a few more patches. But suffice it to say when I am done none of the generic irq code even knows what a vector is. In quick testing on a large Unisys x86_64 machine we stumbled over at least one driver that assumed that NR_IRQS could always fit into an 8 bit number. This driver is clearly buggy today. But this has become a class of bugs that it is now much easier to hit. This patch: This is a minor space optimization. In practice I don't think this has any affect because of our alignment constraints and the other fields but there is not point in chewing up an uncessary word and since we already read the flag field this should improve the cache hit ratio of the irq handler.

Disabling the irq needs to happen but sometimes doing the work is move_native_irq is too late. On x86 with ioapics the irq move sequences needs to be: edge_triggered: mask irq. move irq. unmask irq. ack irq. level_triggered: mask irq. ack irq. move irq. unmask irq. We can easily perform the edge triggered sequence, with the current defintion of move_native_irq. However the level triggered case does not map well. For that I have added move_masked_irq, to allow me to disable the irqs around both the ack and the move. Q: Why have we not seen this problem earlier? A: The only symptom I have been able to reproduce is that if we change the vector before acknowleding an irq the wrong irq is acknowledged. Since we currently are not reprogramming the irq vector during migration no problems show up. We have to mask the irq before we acknowledge the irq or else we could hit a window where an irq is asserted just before we acknowledge it. Edge triggered irqs do not have this problem because acknowledgements do not propogate in the same way. Signed-off-by: Eric W.

This is a little cleaner and allows for architectures that need to modify the data to retarget the msi interrupt to a different cpu. - In target pass in the full cpu mask instead of just the first cpu in case we can make use of the full cpu mask. - Operate in terms of irqs and not vectors, currently there is still a 1-1 relationship but on architectures other than ia64 I expect this will change.

Biederman" Date: Wed, 4 Oct 2006 02:16:37 -0700 Subject: [PATCH] genirq: irq: add a dynamic irq creation API With the msi support comes a new concept in irq handling, irqs that are created dynamically at run time. Currently the msi code allocates irqs backwards. First it allocates a platform dependent routing value for an interrupt the ``vector'' and then it figures out from the vector which irq you are on. This msi backwards allocator suffers from two basic problems. The allocator suffers because it is trying to do something that is architecture specific in a generic way making it brittle, inflexible, and tied to tightly to the architecture implementation. The alloctor also suffers from it's very backwards nature as it has tied things together that should have no dependencies. To solve the basic dynamic irq allocation problem two new architecture specific functions are added: create_irq and destroy_irq. create_irq takes no input and returns an unused irq number, that won't be reused until it is returned to the free poll with destroy_irq. The irq then can be used for any purpose although the only initial consumer is the msi code. destroy_irq takes an irq number allocated with create_irq and returns it to the free pool. Making this functionality per architecture increases the simplicity of the irq allocation code and increases it's flexibility. dynamic_irq_init() and dynamic_irq_cleanup() are added to automate the irq_desc initializtion that should happen for dynamic irqs.

Biederman" Date: Wed, 4 Oct 2006 02:16:47 -0700 Subject: [PATCH] genirq: i386 irq: Remove the msi assumption that irq == vector This patch removes the change in behavior of the irq allocation code when CONFIG_PCI_MSI is defined. Removing all instances of the assumption that irq == vector. create_irq is rewritten to first allocate a free irq and then to assign that irq a vector. assign_irq_vector is made static and the AUTO_ASSIGN case which allocates an vector not bound to an irq is removed. The ioapic vector methods are removed, and everything now works with irqs. The definition of NR_IRQS no longer depends on CONFIG_PCI_MSI [akpm@osdl.org: cleanup] Signed-off-by: Eric W.

Biederman" Date: Wed, 4 Oct 2006 02:16:55 -0700 Subject: [PATCH] Initial generic hypertransport interrupt support This patch implements two functions ht_create_irq and ht_destroy_irq for use by drivers. Several other functions are implemented as helpers for arch specific irq_chip handlers. The driver for the card I tested this on isn't yet ready to be merged. However this code is and hypertransport irqs are in use in a few other places in the kernel. Not that any of this will get merged before 2.6.19 Because the ipath-ht400 is slightly out of spec this code will need to be generalized to work there. I think all of the powerpc uses are for a plain interrupt controller in a chipset so support for native hypertransport devices is a little less interesting. However I think this is a half way decent model on how to separate arch specific and generic helper code, and I think this is a functional model of how to get the architecture dependencies out of the msi code.

Biederman" Date: Wed, 4 Oct 2006 02:16:56 -0700 Subject: [PATCH] msi: simplify msi sanity checks by adding with generic irq code Currently msi.c is doing sanity checks that make certain before an irq is destroyed it has no more users. By adding irq_has_action I can perform the test is a generic way, instead of relying on a msi specific data structure. By performing the core check in dynamic_irq_cleanup I ensure every user of dynamic irqs has a test present and we don't free resources that are in use. In msi.c this allows me to kill the attrib.state member of msi_desc and all of the assciated code to maintain it. To keep from freeing data structures when irq cleanup code is called to soon changing dyanamic_irq_cleanup is insufficient because there are msi specific data structures that are also not safe to free.

Biederman" Date: Wed, 4 Oct 2006 02:16:59 -0700 Subject: [PATCH] msi: refactor and move the msi irq_chip into the arch code It turns out msi_ops was simply not enough to abstract the architecture specific details of msi. So I have moved the resposibility of constructing the struct irq_chip to the architectures, and have two architecture specific functions arch_setup_msi_irq, and arch_teardown_msi_irq. For simple architectures those functions can do all of the work. For architectures with platform dependencies they can call into the appropriate platform code. With this msi.c is finally free of assuming you have an apic, and this actually takes less code. The helpers for the architecture specific code are declared in the linux/msi.h to keep them separate from the msi functions used by drivers in linux/pci.h Signed-off-by: Eric W.

McKenney" Date: Wed, 4 Oct 2006 02:17:02 -0700 Subject: [PATCH] srcu-3: RCU variant permitting read-side blocking Updated patch adding a variant of RCU that permits sleeping in read-side critical sections. SRCU is as follows: o Each use of SRCU creates its own srcu_struct, and each srcu_struct has its own set of grace periods. This is critical, as it prevents one subsystem with a blocking reader from holding up SRCU grace periods for other subsystems. o The SRCU primitives (srcu_read_lock(), srcu_read_unlock(), and synchronize_srcu()) all take a pointer to a srcu_struct. o The SRCU primitives must be called from process context. o srcu_read_lock() returns an int that must be passed to the matching srcu_read_unlock(). Realtime RCU avoids the need for this by storing the state in the task struct, but SRCU needs to allow a given code path to pass through multiple SRCU domains -- storing state in the task struct would therefore require either arbitrary space in the task struct or arbitrary limits on SRCU nesting. So I kicked the state-storage problem up to the caller. Of course, it is not permitted to call synchronize_srcu() while in an SRCU read-side critical section. o There is no call_srcu(). It would not be hard to implement one, but it seems like too easy a way to OOM the system. (Hey, we have enough trouble with call_rcu(), which does -not- permit readers to sleep!!!)

An SRCU notifier chain is much like a blocking notifier chain, in that it must be called in process context and its callout routines are allowed to sleep. The difference is that the chain's links are protected by the SRCU mechanism rather than by an rw-semaphore, so calling the chain has extremely low overhead: no memory barriers and no cache-line bouncing. On the other hand, unregistering from the chain is expensive and the chain head requires special runtime initialization (plus cleanup if it is to be deallocated). SRCU notifiers are appropriate for notifiers that will be called very frequently and for which unregistration occurs very seldom. The proposed "task notifier" scheme qualifies, as may some of the network notifiers. Signed-off-by: Alan Stern Acked-by: Paul E.

This patch (as761) makes it return -ENOMEM when the per-cpu data allocation fails. The patch also makes srcu_init_notifier_head() report a BUG if a notifier head can't be initialized. Perhaps it should return -ENOMEM instead, but in the most likely cases where this might occur I don't think any recovery is possible. Notifier chains generally are not created dynamically.

Instead, it adds adds a flag rcu_ctrlblk.signaled, which records the fact that one of CPUs has sent a resched IPI since the last rcu_start_batch(). Roughly speaking, we need two rcu_start_batch()s in order to move callbacks from ->nxtlist to ->donelist. This means that when ->qlen exceeds qhimark and continues to grow, we should send a resched IPI, and then do it again after we gone through a quiescent state. On the other hand, if it was already sent, we don't need to do it again when another CPU detects overflow of the queue. Signed-off-by: Oleg Nesterov Acked-by: Paul E.

The first -is the Maestro 1. It was originally produced by Platform Tech as the -'AGOGO'. It can be recognized by Platform Tech's PCI ID 0x1285 with -0x0100 as the device ID. It was put on some sound boards and a few laptops. -ESS bought the design and cleaned it up as the Maestro 2. This starts -their marking with the ESS vendor ID 0x125D and the 'year' device IDs. -The Maestro 2 claims 0x1968 while the Maestro 2e has 0x1978. - -The various families of Maestro are mostly identical as far as this -driver is concerned. It doesn't touch the DSP parts that differ (though -it could for FM synthesis). - -Driver OSS Behavior --------------------- - -This OSS driver exports /dev/mixer and /dev/dsp to applications, which -mostly adhere to the OSS spec. This driver doesn't register itself -with /dev/sndstat, so don't expect information to appear there. - -The /dev/dsp device exported behaves almost as expected. Playback is -supported in all the various lovely formats. 8/16bit stereo/mono from -8khz to 48khz, and mmap()ing for playback behaves. Capture/recording -is limited due to oddities with the Maestro hardware. One can only -record in 16bit stereo. For recording the maestro uses non interleaved -stereo buffers so that mmap()ing the incoming data does not result in -a ring buffer of LRLR data. mmap()ing of the read buffers is therefore -disallowed until this can be cleaned up. - -/dev/mixer is an interface to the AC'97 codec on the Maestro. It is -worth noting that there are a variety of AC'97s that can be wired to -the Maestro. Which is used is entirely up to the hardware implementor. -This should only be visible to the user by the presence, or lack, of -'Bass' and 'Treble' sliders in the mixer. Not all AC'97s have them. - -The driver doesn't support MIDI or FM playback at the moment. Typically -the Maestro is wired to an MPU MIDI chip, but some hardware implementations -don't. We need to assemble a white list of hardware implementations that -have MIDI wired properly before we can claim to support it safely. - -Compiling and Installing ------------------------- - -With the drivers inclusion into the kernel, compiling and installing -is the same as most OSS/Lite modular sound drivers. Compilation -of the driver is enabled through the CONFIG_SOUND_MAESTRO variable -in the config system. - -It may be modular or statically linked. If it is modular it should be -installed with the rest of the modules for the kernel on the system. -Typically this will be in /lib/modules/ somewhere. 'alias sound maestro' -should also be added to your module configs (typically /etc/conf.modules) -if you're using modular OSS/Lite sound and want to default to using a -maestro chip. - -As this is a PCI device, the module does not need to be informed of -any IO or IRQ resources it should use, it devines these from the -system. Sometimes, on sucky PCs, the BIOS fails to allocated resources -for the maestro. This will result in a message like: - maestro: PCI subsystem reports IRQ 0, this might not be correct. -from the kernel. Should this happen the sound chip most likely will -not operate correctly. To solve this one has to dig through their BIOS -(typically entered by hitting a hot key at boot time) and figure out -what magic needs to happen so that the BIOS will reward the maestro with -an IRQ. This operation is incredibly system specific, so you're on your -own. Sometimes the magic lies in 'PNP Capable Operating System' settings. - -There are very few options to the driver. One is 'debug' which will -tell the driver to print minimal debugging information as it runs. This -can be collected with 'dmesg' or through the klogd daemon. - -The other, more interesting option, is 'dsps_order'. Typically at -install time the driver will only register one available /dev/dsp device -for its use. The 'dsps_order' module parameter allows for more devices -to be allocated, as a power of two. Up to 4 devices can be registered -( dsps_order=2 ). These devices act as fully distinct units and use -separate channels in the maestro. - -Power Management ----------------- - -As of version 0.14, this driver has a minimal understanding of PCI -Power Management. If it finds a valid power management capability -on the PCI device it will attempt to use the power management -functions of the maestro. It will only do this on Maestro 2Es and -only on machines that are known to function well. You can -force the use of power management by setting the 'use_pm' module -option to 1, or can disable it entirely by setting it to 0. - -When using power management, the driver does a few things -differently. It will keep the chip in a lower power mode -when the module is inserted but /dev/dsp is not open. This -allows the mixer to function but turns off the clocks -on other parts of the chip. When /dev/dsp is opened the chip -is brought into full power mode, and brought back down -when it is closed. It also powers down the chip entirely -when the module is removed or the machine is shutdown. This -can have nonobvious consequences. CD audio may not work -after a power managing driver is removed. Also, software that -doesn't understand power management may not be able to talk -to the powered down chip until the machine goes through a hard -reboot to bring it back. - -.. more details .. ------------------- - -drivers/sound/maestro.c contains comments that hopefully explain -the maestro implementation. diff --git a/Documentation/sound/oss/Maestro3 b/Documentation/sound/oss/Maestro3 deleted file mode 100644 index a113718e8034..000000000000 --- a/Documentation/sound/oss/Maestro3 +++ /dev/null @@ -1,92 +0,0 @@ - An OSS/Lite Driver for the ESS Maestro3 family of sound chips - - Zach Brown, January 2001 - -Driver Status and Availability ------------------------------- - -The most recent version of this driver will hopefully always be available at - http://www.zabbo.net/maestro3/ - -I will try and maintain the most recent stable version of the driver -in both the stable and development kernel lines. - -Historically I've sucked pretty hard at actually doing that, however. - -ESS Maestro3 Chip Family ------------------------ - -The 'Maestro3' is much like the Maestro2 chip.

This driver doesn't register itself -with /dev/sndstat, so don't expect information to appear there. - -The /dev/dsp device exported behaves as expected. Playback is -supported in all the various lovely formats. 8/16bit stereo/mono from -8khz to 48khz, with both read()/write(), and mmap(). - -/dev/mixer is an interface to the AC'97 codec on the Maestro3. It is -worth noting that there are a variety of AC'97s that can be wired to -the Maestro3. Which is used is entirely up to the hardware implementor. -This should only be visible to the user by the presence, or lack, of -'Bass' and 'Treble' sliders in the mixer. Not all AC'97s have them. -The Allegro has an onchip AC'97. - -The driver doesn't support MIDI or FM playback at the moment. - -Compiling and Installing ------------------------- - -With the drivers inclusion into the kernel, compiling and installing -is the same as most OSS/Lite modular sound drivers. Compilation -of the driver is enabled through the CONFIG_SOUND_MAESTRO3 variable -in the config system. - -It may be modular or statically linked. If it is modular it should be -installed with the rest of the modules for the kernel on the system. -Typically this will be in /lib/modules/ somewhere. 'alias sound-slot-0 -maestro3' should also be added to your module configs (typically -/etc/modprobe.conf) if you're using modular OSS/Lite sound and want to -default to using a maestro3 chip. - -There are very few options to the driver. One is 'debug' which will -tell the driver to print minimal debugging information as it runs. This -can be collected with 'dmesg' or through the klogd daemon. - -One is 'external_amp', which tells the driver to attempt to enable -an external amplifier. This defaults to '1', you can tell the driver -not to bother enabling such an amplifier by setting it to '0'. - -And the last is 'gpio_pin', which tells the driver which GPIO pin number -the external amp uses (0-15), The Allegro uses 8 by default, all others 1. -If everything loads correctly and seems to be working but you get no sound, -try tweaking this value. - -Systems known to need a different value - Panasonic ToughBook CF-72: gpio_pin=13 - -Power Management ----------------- - -This driver has a minimal understanding of PCI Power Management. It will -try and power down the chip when the system is suspended, and power -it up with it is resumed. It will also try and power down the chip -when the machine is shut down. diff --git a/Documentation/sound/oss/NEWS b/Documentation/sound/oss/NEWS deleted file mode 100644 index a81e0ef72ae9..000000000000 --- a/Documentation/sound/oss/NEWS +++ /dev/null @@ -1,42 +0,0 @@ -Linux 2.4 Sound Changes -2000-September-25 -Christoph Hellwig, - - - -=== isapnp support - -The Linux 2.4 Kernel does have reliable in-kernel isapnp support. -Some drivers (sb.o, ad1816.o awe_wave.o) do now support automatically -detecting and configuring isapnp devices. -If you have a not yet supported isapnp soundcard, mail me the content -of '/proc/isapnp' on your system and some information about your card -and its driver(s) so I can try to get isapnp working for it. - - - -=== soundcard resources on kernel commandline - -Before Linux 2.4 you had to specify the resources for sounddrivers -statically linked into the kernel at compile time -(in make config/menuconfig/xconfig).

The driver is provided for Linux 1.2.x -and 2.[012].x kernels, as well as FreeBSD, on Intel x86 and DEC -Alpha systems. - -This driver was written by Takashi Iwai , -and provided "as is". The original source (awedrv-0.4.3.tar.gz) and -binary packages are available on the following URL: - http://bahamut.mm.t.u-tokyo.ac.jp/~iwai/awedrv/ -Note that since the author is apart from this web site, the update is -not frequent now. - - -* NOTE TO LINUX USERS - -To enable this driver on linux-2.[01].x kernels, you need turn on -"AWE32 synth" options in sound menu when configure your linux kernel -and modules. The precise installation procedure is described in the -AWE64-Mini-HOWTO and linux-kernel/Documetation/sound/AWE32. - -If you're using PnP cards, the card must be initialized before loading -the sound driver. There're several options to do this: - - Initialize the card via ISA PnP tools, and load the sound module. - - Initialize the card on DOS, and load linux by loadlin.exe - - Use PnP kernel driver (for Linux-2.x.x) -The detailed instruction for the solution using isapnp tools is found -in many documents like above. A brief instruction is also included in -the installation document of this package. -For PnP driver project, please refer to the following URL: - http://www-jcr.lmh.ox.ac.uk/~pnp/ - - -* USING THE DRIVER - -The awedrv has several different playing modes to realize easy channel -allocation for MIDI songs. To hear the exact sound quality, you need -to obtain the extended sequencer program, drvmidi or playmidi-2.5. - -For playing MIDI files, you *MUST* load the soundfont file on the -driver previously by sfxload utility. Otherwise you'll here no sounds -at all! All the utilities and driver source packages are found in the -above URL. The sfxload program is included in the package -awesfx-0.4.3.tgz.

Because of Alan Cox's work on modularizing the sound -drivers, and now backporting them to 2.0.34 kernels, there seems to be -little reason to support "static" configuration variables, and so this -has been abandoned in favor of *only* module parameters. Specifying -"mpuio" and "mpuirq" for the cs4232 parameter will result in the -CS4232 MIDI interface being configured; leaving them unspecified will -leave it unconfigured (and thus unusable). - -BTW, I have heard from one Tropez+ user that the CS4232 interface is -more reliable than the ICS2115 one.

To allow this -the driver/soundcard supports two PCM (/dev/dsp) interfaces. -The second one goes to the mixer "synth" setting and supports -only a limited set of sampling rates (44100, 22050, 11025, 5512). -By setting lineout to 1 on the driver command line -(eg. insmod es1370 lineout=1) it is even possible on some -cards to convert the LINEIN jack into a second LINEOUT jack, thus -making it possible to output four independent audio channels! - -There is a freely available software package that allows -MIDI file playback on this soundcard called Timidity. -See http://www.cgs.fi/~tt/timidity/. - - - -Thomas Sailer -t.sailer@alumni.ethz.ch diff --git a/Documentation/sound/oss/rme96xx b/Documentation/sound/oss/rme96xx deleted file mode 100644 index 87d7b7b65fa1..000000000000 --- a/Documentation/sound/oss/rme96xx +++ /dev/null @@ -1,767 +0,0 @@ -Beta release of the rme96xx (driver for RME 96XX cards like the -"Hammerfall" and the "Hammerfall light") - -Important: The driver module has to be installed on a freshly rebooted system, -otherwise the driver might not be able to acquire its buffers. - -features: - - - OSS programming interface (i.e. runs with standard OSS soundsoftware) - - OSS/Multichannel interface (OSS multichannel is done by just aquiring - more than 2 channels).

Many thanks to Howard Kim for providing - * contacts and hardware. Honorable mention goes to Eric - * Brombaugh for all sorts of things. Best regards to the - * proprietors of Hack Central for fine lodging. - * - * Supported devices: - * /dev/dsp0-3 standard /dev/dsp device, (mostly) OSS compatible - * /dev/mixer standard /dev/mixer device, (mostly) OSS compatible - * - * Hardware Description - * - * A working Maestro setup contains the Maestro chip wired to a - * codec or 2. In the Maestro we have the APUs, the ASSP, and the - * Wavecache. The APUs can be though of as virtual audio routing - * channels. They can take data from a number of sources and perform - * basic encodings of the data. The wavecache is a storehouse for - * PCM data. Typically it deals with PCI and interracts with the - * APUs. The ASSP is a wacky DSP like device that ESS is loth - * to release docs on. Thankfully it isn't required on the Maestro - * until you start doing insane things like FM emulation and surround - * encoding. The codecs are almost always AC-97 compliant codecs, - * but it appears that early Maestros may have had PT101 (an ESS - * part?) wired to them. The only real difference in the Maestro - * families is external goop like docking capability, memory for - * the ASSP, and initialization differences. - * - * Driver Operation - * - * We only drive the APU/Wavecache as typical DACs and drive the - * mixers in the codecs. There are 64 APUs. We assign 6 to each - * /dev/dsp? device. 2 channels for output, and 4 channels for - * input. - * - * Each APU can do a number of things, but we only really use - * 3 basic functions. For playback we use them to convert PCM - * data fetched over PCI by the wavecahche into analog data that - * is handed to the codec. One APU for mono, and a pair for stereo. - * When in stereo, the combination of smarts in the APU and Wavecache - * decide which wavecache gets the left or right channel. - * - * For record we still use the old overly mono system. For each in - * coming channel the data comes in from the codec, through a 'input' - * APU, through another rate converter APU, and then into memory via - * the wavecache and PCI. If its stereo, we mash it back into LRLR in - * software. The pass between the 2 APUs is supposedly what requires us - * to have a 512 byte buffer sitting around in wavecache/memory. - * - * The wavecache makes our life even more fun. First off, it can - * only address the first 28 bits of PCI address space, making it - * useless on quite a few architectures. Secondly, its insane. - * It claims to fetch from 4 regions of PCI space, each 4 meg in length. - * But that doesn't really work. You can only use 1 region. So all our - * allocations have to be in 4meg of each other. Booo. Hiss. - * So we have a module parameter, dsps_order, that is the order of - * the number of dsps to provide. All their buffer space is allocated - * on open time. The sonicvibes OSS routines we inherited really want - * power of 2 buffers, so we have all those next to each other, then - * 512 byte regions for the recording wavecaches. This ends up - * wasting quite a bit of memory. The only fixes I can see would be - * getting a kernel allocator that could work in zones, or figuring out - * just how to coerce the WP into doing what we want. - * - * The indirection of the various registers means we have to spinlock - * nearly all register accesses. We have the main register indirection - * like the wave cache, maestro registers, etc. Then we have beasts - * like the APU interface that is indirect registers gotten at through - * the main maestro indirection. Ouch. We spinlock around the actual - * ports on a per card basis. This means spinlock activity at each IO - * operation, but the only IO operation clusters are in non critical - * paths and it makes the code far easier to follow. Interrupts are - * blocked while holding the locks because the int handler has to - * get at some of them :(. The mixer interface doesn't, however. - * We also have an OSS state lock that is thrown around in a few - * places. - * - * This driver has brute force APM suspend support. We catch suspend - * notifications and stop all work being done on the chip. Any people - * that try between this shutdown and the real suspend operation will - * be put to sleep. When we resume we restore our software state on - * the chip and wake up the people that were using it. The code thats - * being used now is quite dirty and assumes we're on a uni-processor - * machine. Much of it will need to be cleaned up for SMP ACPI or - * similar. - * - * We also pay attention to PCI power management now. The driver - * will power down units of the chip that it knows aren't needed. - * The WaveProcessor and company are only powered on when people - * have /dev/dsp*s open. On removal the driver will - * power down the maestro entirely. There could still be - * trouble with BIOSen that magically change power states - * themselves, but we'll see. - * - * History - * v0.15 - May 21 2001 - Marcus Meissner - * Ported to Linux 2.4 PCI API.

The core of the - * chip is the 'assp', the custom ESS dsp that runs the show. It has - * a small amount of code and data ram. ESS drops binary dsp code images - * on our heads, but we don't get to see specs on the dsp. - * - * The constant piece of code on the dsp is the 'kernel'. It also has a - * chunk of the dsp memory that is statically set aside for its control - * info. This is the KDATA defines in maestro3.h. Part of its core - * data is a list of code addresses that point to the pieces of DSP code - * that it should walk through in its loop. These other pieces of code - * do the real work. The kernel presumably jumps into each of them in turn. - * These code images tend to have their own data area, and one can have - * multiple data areas representing different states for each of the 'client - * instance' code portions. There is generally a list in the kernel data - * that points to the data instances for a given piece of code. - * - * We've only been given the binary image for the 'minisrc', mini sample - * rate converter. This is rather annoying because it limits the work - * we can do on the dsp, but it also greatly simplifies the job of managing - * dsp data memory for the code and data for our playing streams :). We - * statically allocate the minisrc code into a region we 'know' to be free - * based on the map of the binary kernel image we're loading. We also - * statically allocate the data areas for the maximum number of pcm streams - * we can be dealing with. This max is set by the length of the static list - * in the kernel data that records the number of minisrc data regions we - * can have. Thats right, all software dsp mixing with static code list - * limits. Rock. - * - * How sound goes in and out is still a relative mystery. It appears - * that the dsp has the ability to get input and output through various - * 'connections'. To do IO from or to a connection, you put the address - * of the minisrc client area in the static kernel data lists for that - * input or output. so for pcm -> dsp -> mixer, we put the minisrc data - * instance in the DMA list and also in the list for the mixer. I guess - * it Just Knows which is in/out, and we give some dma control info that - * helps. There are all sorts of cool inputs/outputs that it seems we can't - * use without dsp code images that know how to use them. - * - * So at init time we preload all the memory allocation stuff and set some - * system wide parameters. When we really get a sound to play we build - * up its minisrc header (stream parameters, buffer addresses, input/output - * settings). Then we throw its header on the various lists. We also - * tickle some KDATA settings that ask the assp to raise clock interrupts - * and do some amount of software mixing before handing data to the ac97. - * - * Sorry for the vague details. Feel free to ask Eric or myself if you - * happen to be trying to use this driver elsewhere. Please accept my - * apologies for the quality of the OSS support code, its passed through - * too many hands now and desperately wants to be rethought. - */ - -/*****************************************************************************/ - -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include - - -#include -#include -#include - -#include "maestro3.h" - -#define M_DEBUG 1 - -#define DRIVER_VERSION "1.23" -#define M3_MODULE_NAME "maestro3" -#define PFX M3_MODULE_NAME ": " - -#define M3_STATE_MAGIC 0x734d724d -#define M3_CARD_MAGIC 0x646e6f50 - -#define ESS_FMT_STEREO 0x01 -#define ESS_FMT_16BIT 0x02 -#define ESS_FMT_MASK 0x03 -#define ESS_DAC_SHIFT 0 -#define ESS_ADC_SHIFT 4 - -#define DAC_RUNNING 1 -#define ADC_RUNNING 2 - -#define SND_DEV_DSP16 5 - -#ifdef M_DEBUG -static int debug; -#define DPMOD 1 /* per module load */ -#define DPSTR 2 /* per 'stream' */ -#define DPSYS 3 /* per syscall */ -#define DPCRAP 4 /* stuff the user shouldn't see unless they're really debuggin */ -#define DPINT 5 /* per interrupt, LOTS */ -#define DPRINTK(DP, args...) {if (debug >= (DP)) printk(KERN_DEBUG PFX args);} -#else -#define DPRINTK(x) -#endif - -struct m3_list { - int curlen; - u16 mem_addr; - int max; -}; - -static int external_amp = 1; -static int gpio_pin = -1; - -struct m3_state { - unsigned int magic; - struct m3_card *card; - unsigned char fmt, enable; - - int index; - - /* this locks around the oss state in the driver */ - /* no, this lock is removed - only use card->lock */ - /* otherwise: against what are you protecting on SMP - when irqhandler uses s->lock - and m3_assp_read uses card->lock ?

This got around the limitation that ioremap() isn't always available when the console is being initalized. This patch removes that hack and replaces it with a new "regs" field in struct atmel_uart_data that the board-specific code can initialize to a fixed virtual mapping for platform devices where this is possible. It also initializes the DBGU's regs field with the address the driver used to check against. On AVR32, the "regs" field is initialized from the physical base address when this it can be accessed through a permanently 1:1 mapped segment, i.e. the P4 segment. If regs is NULL, the console initialization is delayed until the "real" driver is up and running and ioremap() can be used.

This ensures that even though ATSTK1002 uses USART1 as the first serial port, it will still have a ttyS0 device. This also adds a board-specific early setup hook and moves the at32_setup_serial_console() call there from the platform code.

This patch adds NUMA support to the the spufs scheduler. The new arch/powerpc/platforms/cell/spufs/sched.c is greatly simplified, in an attempt to reduce complexity while adding support for NUMA scheduler domains. SPUs are allocated starting from the calling thread's node, moving to others as supported by current->cpus_allowed. Preemption is gone as it was buggy, but should be re-enabled in another patch when stable. The new arch/powerpc/platforms/cell/spu_base.c maintains idle lists on a per-node basis, and allows caller to specify which node(s) an SPU should be allocated from, while passing -1 tells spu_alloc() that any node is allowed. Since the patch removes the currently implemented preemptive scheduling, it is technically a regression, but practically all users have since migrated to this version, as it is part of the IBM SDK and the yellowdog distribution, so there is not much point holding it back while the new preemptive scheduling patch gets delayed further.

Fortunately, libspe has never been using the returned contents of that register, as they were the same as the return code of spu_run (duh!). Unlike the specification that we never implemented correctly, we now require a SPU_CREATE_EVENTS_ENABLED flag passed to spu_create, in order to get the new behavior. When this flag is not passed, spu_run will simply ignore the third argument now.

So far, this has no impact whatsover on scheduling, but makes it possible to add that later. A new type of object in spufs is now a spu_gang. It is created with the spu_create system call with the flags argument set to SPU_CREATE_GANG (0x2). Inside of a spu_gang, it is then possible to create spu_context objects, which until now was only possible at the root of spufs. There is a new member in struct spu_context pointing to the spu_gang it belongs to, if any. The spu_gang maintains a list of spu_context structures that are its children. This information can then be used in the scheduler in the future. There is still a bug that needs to be resolved in this basic infrastructure regarding the order in which objects are removed. When the spu_gang file descriptor is closed before the spu_context descriptors, we leak the dentry and inode for the gang. Any ideas how to cleanly solve this are appreciated.

This was originally meant for use by oprofile, but is now also used by the GNU debugger, if available. In order for oprofile to find the location in an spu-elf binary where an event counter triggered, we need a way to identify the binary in the first place. Unfortunately, that binary itself can be embedded in a powerpc ELF binary. Since we can assume it is mapped into the effective address space of the running process, have that one write the pointer value into a new spufs file. When a context switch occurs, pass the user value to the profiler so that can look at the mapped file (with some care).

The regs pointer is used in few places, but it potentially costs both stack space and code to pass it around. On the FRV arch, removing the regs parameter from all the genirq function results in a 20% speed up of the IRQ exit path (ie: from leaving timer_interrupt() to leaving do_IRQ()). Where appropriate, an arch may override the generic storage facility and do something different with the variable. On FRV, for instance, the address is maintained in GR28 at all times inside the kernel as part of general exception handling. Having looked over the code, it appears that the parameter may be handed down through up to twenty or so layers of functions. Consider a USB character device attached to a USB hub, attached to a USB controller that posts its interrupts through a cascaded auxiliary interrupt controller. A character device driver may want to pass regs to the sysrq handler through the input layer which adds another few layers of parameter passing. I've build this code with allyesconfig for x86_64 and i386. I've runtested the main part of the code on FRV and i386, though I can't test most of the drivers. I've also done partial conversion for powerpc and MIPS - these at least compile with minimal configurations. This will affect all archs. Mostly the changes should be relatively easy. Take do_IRQ(), store the regs pointer at the beginning, saving the old one: struct pt_regs *old_regs = set_irq_regs(regs); And put the old one back at the end: set_irq_regs(old_regs); Don't pass regs through to generic_handle_irq() or __do_IRQ(). In timer_interrupt(), this sort of change will be necessary: - update_process_times(user_mode(regs)); - profile_tick(CPU_PROFILING, regs); + update_process_times(user_mode(get_irq_regs())); + profile_tick(CPU_PROFILING); I'd like to move update_process_times()'s use of get_irq_regs() into itself, except that i386, alone of the archs, uses something other than user_mode(). Some notes on the interrupt handling in the drivers: (*) input_dev() is now gone entirely. The regs pointer is no longer stored in the input_dev struct. (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking. It does something different depending on whether it's been supplied with a regs pointer or not. (*) Various IRQ handler function pointers have been moved to type irq_handler_t.

As boards start providing their own clocksources, they're able to select GENERIC_TIME accordingly and optimize out most of the timer API. Once the current timers have been reworked as proper clocksource drivers, the rest of the place holders for the timer API can go away and we can flip on GENERIC_TIME unconditionally.

Apparently due to the access to the newly-added static variable. Rearrange the code so that we don't touch that variable unless the warning is going to trigger. Also rework the logic so that the static variable starts out at zero, so we can move it into bss. It would seem logical to mark the static variable as __read_mostly too. But it would be wrong, because that would put it back into the vmlinux image, and the kernel will never read from this variable in normal operation anyway. Unless the compiler or hardware go and do some prefetching on us? For some reason this patch shrinks softirq.o text by 40 bytes.

It goes back to userland on page faults and just tries again in get_user_pages(). I added a cond_resched() in the loop in that later case. The problem I have with signal and spufs is an actual bug affecting apps and I don't see other ways of fixing it. In addition, we are having issues with infiniband and 64k pages (related to the way the hypervisor deals with some HV cards) that will require us to muck around with the MMU from within the IB driver's no_page() (it's a pSeries specific driver) and return to the caller the same way using NOPAGE_REFAULT. And to add to this, the graphics folks have been following a new approach of memory management that involves transparently swapping objects between video ram and main meory. To do that, they need installing PTEs from a no_page() handler as well and that also requires returning with NOPAGE_REFAULT. (For the later, they are currently using io_remap_pfn_range to install one PTE from no_page() which is a bit racy, we need to add a check for the PTE having already been installed afer taking the lock, but that's ok, they are only at the proof-of-concept stage. I'll send a patch adding a "clean" function to do that, we can use that from spufs too and get rid of the sparsemem hacks we do to create struct page for SPEs. Basically, that provides a generic solution for being able to have no_page() map hardware devices, which is something that I think sound driver folks have been asking for some time too). All of these things depend on having the NOPAGE_REFAULT exit path from no_page() handlers.

In some cases it is the largest message that can be sent or received. In other cases it is the largest 'payload' that can be included in a NFS message. In either case, it is not possible for both the request and the reply to be this large. One of the request or reply may only be one page long, which fits nicely with NFS. So we remove 'bufsz' and replace it with two numbers: 'max_payload' and 'max_mesg'. Max_payload is the size that the server requests. It is used by the server to check the max size allowed on a particular connection: depending on the protocol a lower limit might be used. max_mesg is the largest single message that can be sent or received. It is calculated as the max_payload, rounded up to a multiple of PAGE_SIZE, and with PAGE_SIZE added to overhead. Only one of the request and reply may be this size. The other must be at most one page. Cc: Greg Banks Cc: "J.

This led to oopses sometimes when file->f_op was freed before __fput() finished. Patch adds a virtual device for disconnect: VDD. VDD consists of: LIST_HEAD(shutdown_files) protected by DEFINE_SPINLOCK(shutdown_mutex) static struct file_operations snd_shutdown_f_ops and functions assigned to it Additions to struct snd_monitor_file to specify if instance is hidden by VDD or not.

Biederman" Date: Sun, 8 Oct 2006 07:47:55 -0600 Subject: [PATCH] x86_64 irq: Allocate a vector across all cpus for genapic_flat. The problem we can't take advantage of lowest priority delivery mode if the vectors are allocated for only one cpu at a time. Nor can we work around hardware that assumes lowest priority delivery mode is always used with several cpus. So this patch introduces the concept of a vector_allocation_domain. A set of cpus that will receive an irq on the same vector. Currently the code for implementing this is placed in the genapic structure so we can vary this depending on how we are using the io_apics. This allows us to restore the previous behaviour of genapic_flat without removing the benefits of having separate vector allocation for large machines. This should also fix the problem report where a hyperthreaded cpu was receving the irq on the wrong hyperthread when in logical delivery mode because the previous behaviour is restored. This patch properly records our allocation of the first 16 irqs to the first 16 available vectors on all cpus. This should be fine but it may run into problems with multiple interrupts at the same interrupt level. Except for some badly maintained comments in the code and the behaviour of the interrupt allocator I have no real understanding of that problem. Signed-off-by: Eric W.

Proposed fix: - make "writer holds lock" distinguishable from "reader tries to grab lock" - have __raw_read_trylock() try to acquire the mutex (in LSB of lock), terminating spin if we see that there's writer holding it. Then do the rest as we do in read_lock(). Thanks to Ingo for discussion...

The code for vfs_listxattr was originally submitted by Bill Nottingham to Unionfs. Sorry about that. The reason for this submission is to make the listxattr code in fs/xattr.c a little cleaner (as well as to clean up some code in Unionfs.) Currently, Unionfs has vfs_listxattr defined in its code. I think that's very ugly, and I'd like to see it (re)moved. The logical place to put it, is along side of all the other vfs_*xattr functions. Overall, I think this patch is benefitial for both kernel.org kernel and Unionfs.

The problem is that hugetlb pages can be shared by multiple mappings. Multiple threads can fight over page->lru in the unmap path and bad things happen. We now serialize __unmap_hugepage_range to void concurrent linked list manipulation. Such serialization is also needed for shared page table page on hugetlb area. This patch will fixed the bug and also serve as a prepatch for shared page table.

In the short term, we can do this by reuse (on-disk) 16-bit padding (linux2.i_pad1 currently used only by "hurd") as high order bits for xattr. This patch basically does that.

The definition of epoll_pwait is: int epoll_pwait(int epfd, struct epoll_event *events, int maxevents, int timeout, const sigset_t *sigmask, size_t sigsetsize); The difference between the vanilla epoll_wait and epoll_pwait is that the latter allows the caller to specify a signal mask to be set while waiting for events. Hence epoll_pwait will wait until either one monitored event, or an unmasked signal happen. If sigmask is NULL, the epoll_pwait system call will act exactly like epoll_wait.

I found a few possible problems in sched.c. This patch may be not measurable, but when I did measure long ago, nooping (un)likely cost a couple of % on scheduler heavy benchmarks, so it all adds up. Tweak some branch hints: - the 2nd 64 bits in the bitmask is likely to be populated, because it contains the first 28 bits (nearly 3/4) of the normal priorities. (ratio of 669669:691 ~= 1000:1). - it isn't unlikely that context switching switches to another process. it might be very rapidly switching to and from the idle process (ratio of 475815:419004 and 471330:423544). Let the branch predictor decide. - preempt_enable seems to be very often called in a nested preempt_disable or with interrupts disabled (ratio of 3567760:87965 ~= 40:1) Signed-off-by: Nick Piggin Acked-by: Ingo Molnar Cc: Daniel Walker Cc: Hua Zhong Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- include/asm-generic/bitops/sched.h | 2 +- kernel/sched.c | 6 +++--- 2 files changed, 4 insertions(+), 4 deletions(-) (limited to 'include') diff --git a/include/asm-generic/bitops/sched.h b/include/asm-generic/bitops/sched.h index 5ef93a4d009f..815bb0148060 100644 --- a/include/asm-generic/bitops/sched.h +++ b/include/asm-generic/bitops/sched.h @@ -15,7 +15,7 @@ static inline int sched_find_first_bit(const unsigned long *b) #if BITS_PER_LONG == 64 if (unlikely(b[0])) return __ffs(b[0]); - if (unlikely(b[1])) + if (likely(b[1])) return __ffs(b[1]) + 64; return __ffs(b[2]) + 128; #elif BITS_PER_LONG == 32 diff --git a/kernel/sched.c b/kernel/sched.c index 53608a59d6e3..094b5687eef6 100644 --- a/kernel/sched.c +++ b/kernel/sched.c @@ -1822,14 +1822,14 @@ context_switch(struct rq *rq, struct task_struct *prev, struct mm_struct *mm = next->mm; struct mm_struct *oldmm = prev->active_mm; - if (unlikely(!mm)) { + if (!mm) { next->active_mm = oldmm; atomic_inc(&oldmm->mm_count); enter_lazy_tlb(oldmm, next); } else switch_mm(oldmm, mm, next); - if (unlikely(!prev->mm)) { + if (!prev->mm) { prev->active_mm = NULL; WARN_ON(rq->prev_mm); rq->prev_mm = oldmm; @@ -3491,7 +3491,7 @@ asmlinkage void __sched preempt_schedule(void) * If there is a non-zero preempt_count or interrupts are disabled, * we do not want to preempt the current task.

The formers include: HDIO_GET_WCACHE, HDIO_GET_ACOUSTIC, HDIO_GET_ADDRESS and HDIO_GET_BUSSTATE. The latters are: HDIO_SET_MULTCOUNT, HDIO_SET_UNMASKINTR, HDIO_SET_KEEPSETTINGS, HDIO_SET_32BIT, HDIO_SET_NOWERR, HDIO_SET_DMA, HDIO_SET_PIO_MODE and HDIO_SET_NICE. Additionally 0x330 used to be HDIO_GETGEO_BIG and may be issued by 32-bit `hdparm' run on a 64-bit kernel making Linux complain loudly. This is a fix for these issues. Signed-off-by: Maciej W.

This seemed to have originated from the way the write_proc function of the /proc filesystem operates. This has been reworked to not use kmalloc and eliminates a lot of get_user() overhead by performing one access_ok before using __get_user(). We need to test if we are in kernel or user space (is_user) and access the buffer differently. We cannot use __get_user() to access kernel addresses in all cases, for example in architectures with separate address space for kernel and user. This function will be useful for other uses as well; for example, taking input for /sysfs instead of /proc, so it was changed to accept kernel buffers. We have this use for the Linux UWB project, as part as the upcoming bandwidth allocator code. Only a few routines used this function and they were changed too.

(2) Destroying every entry in the anon list, one at a time. (3) Each entry in the anon list has its subtree consumed from the leaves inwards. This reduces the amount of work generic_shutdown_super() does, and avoids iterating through the dentry_unused list. Note that locking is almost entirely absent in the shrink_dcache_for_umount*() functions added by this patch. This is because: (1) at the point the filesystem calls generic_shutdown_super(), it is not permitted to further touch the superblock's set of dentries, and nor may it remove aliases from inodes; (2) the dcache memory shrinker now skips dentries that are being unmounted; and (3) the superblock no longer has any external references through which the VFS can reach it. Given these points, the only locking we need to do is when we remove dentries from the unused list and the name hashes, which we do a directory's worth at a time. We also don't need to guard against reference counts going to zero unexpectedly and removing bits of the tree we're working on as nothing else can call dput(). A cut down version of dentry_iput() has been folded into shrink_dcache_for_umount_subtree() function. Apart from not needing to unlock things, it also doesn't need to check for inotify watches. In this version of the patch, the complaint about a dentry still being in use has been expanded from a single BUG_ON() and now gives much more information.

We were not handling that correctly, and in fact inverting the return logic and propagating a false "ok" back up to xfrm_lookup(), which then allowed packets to pass as if they were not associated with an xfrm policy. The way I was seeing the problem was when connecting via IPsec to a confined service on an SELinux box (vsftpd), which did not have the appropriate SELinux policy permissions to send packets via IPsec. The first SYNACK would be blocked, because of an uncached lookup via flow_cache_lookup(), which would fail to resolve an xfrm policy because the SELinux policy is checked at that point via the resolver. However, retransmitted SYNACKs would then find a cached flow entry when calling into flow_cache_lookup() with a null xfrm policy, which is interpreted by xfrm_lookup() as the packet not having any associated policy and similarly to the first case, allowing it to pass without transformation. The solution presented here is to first ensure that errno values are correctly propagated all the way back up through the various call chains from security_xfrm_policy_lookup(), and handled correctly. Then, flow_cache_lookup() is modified, so that if the policy resolver fails (typically a permission denied via the security module), the flow cache entry is killed rather than having a null policy assigned (which indicates that the packet can pass freely). This also forces any future lookups for the same flow to consult the security module (e.g. SELinux) for current security policy (rather than, say, caching the error on the flow cache entry).

In the absence of such an explicitly added SELinux policy rule, the IPSec policy rule fails to match and so the packet(s) flow in clear text without the otherwise applicable xfrm(s) applied. The above SELinux behavior violates the SELinux security notion of "deny by default" which should actually translate to "encrypt by default" in the above case. This was first reported by Evgeniy Polyakov and the way James Morris was seeing the problem was when connecting via IPsec to a confined service on an SELinux box (vsftpd), which did not have the appropriate SELinux policy permissions to send packets via IPsec. With this patch applied, SELinux "polmatching" of flows Vs. IPSec policy rules will only come into play when there's a explicit context specified for the IPSec policy rule (which also means there's corresponding SELinux policy allowing appropriate domains/flows to polmatch to this context). Secondly, when a security module is loaded (in this case, SELinux), the security_xfrm_policy_lookup() hook can return errors other than access denied, such as -EINVAL. We were not handling that correctly, and in fact inverting the return logic and propagating a false "ok" back up to xfrm_lookup(), which then allowed packets to pass as if they were not associated with an xfrm policy. The solution for this is to first ensure that errno values are correctly propagated all the way back up through the various call chains from security_xfrm_policy_lookup(), and handled correctly. Then, flow_cache_lookup() is modified, so that if the policy resolver fails (typically a permission denied via the security module), the flow cache entry is killed rather than having a null policy assigned (which indicates that the packet can pass freely). This also forces any future lookups for the same flow to consult the security module (e.g. SELinux) for current security policy (rather than, say, caching the error on the flow cache entry). This patch: Fix the selinux side of things. This makes sure SELinux polmatching of flow contexts to IPSec policy rules comes into play only when an explicit context is associated with the IPSec policy rule. Also, this no longer defaults the context of a socket policy to the context of the socket since the "no explicit context" case is now handled properly.

When doing receiver buffer accounting, we always used skb->truesize. This is problematic when processing bundled DATA chunks because for every DATA chunk that could be small part of one large skb, we would charge the size of the entire skb. The new approach is to store the size of the DATA chunk we are accounting for in the sctp_ulpevent structure and use that stored value for accounting.

Refer: Intel Architecture Software Developer's Manual http://www.intel.com/design/Pentium4/manuals/253668.htm Platform firmware exports the support for Native C-state to OS using ACPI _PDC and _CST methods. Refer: Intel Processor Vendor-Specific ACPI: Interface Specification http://www.intel.com/technology/iapc/acpi/downloads/302223.htm With Processor Native C-state, we use 'MWAIT' instruction on the processor to enter different C-states (C1, C2, C3). We won't use the special IO ports to enter C-state and no SMM mode etc required to enter C-state. Overall this will mean better C-state support. One major advantage of using MWAIT for all C-states is, with this and "treat interrupt as break event" feature of MWAIT, we can now get accurate timing for the time spent in C1, C2, .. states.

The old _read(), _write(), _query() are just special cases of these functions. Then unified the code in acpi_ec_poll_transaction() and acpi_ec_intr_transaction() a little more. Both functions are now just wrappers around the new acpi_ec_transaction_unlocked() function. The latter contains the EC access logic, the two original function now just do their special way of locking and call the the new function for the actual work. This saves a lot of very similar code. The primary reason for doing this, however, is that my driver for MSI 270 laptops needs to issue some non-standard EC commands in a safe way. Due to this I added a new exported function similar to ec_write()/ec_write() which is called ec_transaction() and is essentially just a wrapper around acpi_ec_{poll,intr}_transaction().

This makes FRV consistent with other archs. Furthermore, the compiler barrier effects are now there unconditionally - at least as far as preemption is concerned - because we don't want the compiler moving memory accesses out of the section of code in which the mapping is in force - in effect the kmap_atomic() must imply a LOCK-class barrier and the kunmap_atomic() must imply an UNLOCK-class barrier to the compiler.

We solve the problem by introducing a pointer to associated address space into the buffer_head. When a buffer is removed from a list of metadata buffers associated with an address space, IO error is transferred from the buffer to the address space, so that fsync can later report it.

That is done without holding the page table lock. This clashes with the way how ptep_clear_flush removes active page table entries from the system. First the ipte instruction is used to invalidate the pte and remove all plt entries for the page. The ipte sets the hardware invalid bit without changing any other bit. After the ipte finished the pte is cleared. A concurrent fault can observe the the previously valid pte with the invalid bit set. With the current encoding of the different pte types an invalidated read-only pte can be misinterpreted as a swap-pte.

Assuming no other add-in ethernet ports in the system, Linux 2.4 kernels name these eth0 and eth1 respectively. Many people have come to expect this naming. Linux 2.6 kernels name these eth1 and eth0 respectively (backwards from expectations). I also have reports that various Sun and HP servers have similar behavior. Root cause: Linux 2.4 kernels walk the pci_devices list, which happens to be sorted in breadth-first order (or pcbios_find_device order on i386, which most often is breadth-first also). 2.6 kernels have both the pci_devices list and the pci_bus_type.klist_devices list, the latter is what is walked at driver load time to match the pci_id tables; this klist happens to be in depth-first order. On systems where, for physical routing reasons, NIC1 appears on a lower bus number than NIC2, but NIC2's bridge is discovered first in the depth-first ordering, NIC2 will be discovered before NIC1. If the list were sorted breadth-first, NIC1 would be discovered before NIC2. A PowerEdge 1955 system has the following topology which easily exhibits the difference between depth-first and breadth-first device lists. -[0000:00]-+-00.0 Intel Corporation 5000P Chipset Memory Controller Hub +-02.0-[0000:03-08]--+-00.0-[0000:04-07]--+-00.0-[0000:05-06]----00.0-[0000:06]----00.0 Broadcom Corporation NetXtreme II BCM5708S Gigabit Ethernet (labeled NIC2, 2.4 kernel name eth1, 2.6 kernel name eth0) +-1c.0-[0000:01-02]----00.0-[0000:02]----00.0 Broadcom Corporation NetXtreme II BCM5708S Gigabit Ethernet (labeled NIC1, 2.4 kernel name eth0, 2.6 kernel name eth1) Other factors, such as device driver load order and the presence of PCI slots at various points in the bus hierarchy further complicate this problem; I'm not trying to solve those here, just restore the device order, and thus basic behavior, that 2.4 kernels had. Solution: The solution can come in multiple steps. Suggested fix #1: kernel Patch below optionally sorts the two device lists into breadth-first ordering to maintain compatibility with 2.4 kernels. It adds two new command line options: pci=bfsort pci=nobfsort to force the sort order, or not, as you wish. It also adds DMI checks for the specific Dell systems which exhibit "backwards" ordering, to make them "right". Suggested fix #2: udev rules from userland Many people also have the expectation that embedded NICs are always discovered before add-in NICs (which this patch does not try to do). Using the PCI IRQ Routing Table provided by system BIOS, it's easy to determine which PCI devices are embedded, or if add-in, which PCI slot they're in. I'm working on a tool that would allow udev to name ethernet devices in ascending embedded, slot 1 .. slot N order, subsort by PCI bus/dev/fn breadth-first. It'll be possible to use it independent of udev as well for those distributions that don't use udev in their installers. Suggested fix #3: system board routing rules One can constrain the system board layout to put NIC1 ahead of NIC2 regardless of breadth-first or depth-first discovery order. This adds a significant level of complexity to board routing, and may not be possible in all instances (witness the above systems from several major manufacturers). I don't want to encourage this particular train of thought too far, at the expense of not doing #1 or #2 above. Feedback appreciated. Patch tested on a Dell PowerEdge 1955 blade with 2.6.18. You'll also note I took some liberty and temporarily break the klist abstraction to simplify and speed up the sort algorithm. I think that's both safe and appropriate in this instance.

On slow links, deferring causes significant bursts. See attached plots, which show RTT through a 1 Mbps link with a 100 ms RTT and ~100 ms queue for (a) non-TSO, (b) currnet TSO, and (c) patched TSO. This burstiness causes significant jitter, tends to overflow queues early (bad for short queues), and makes delay-based congestion control more difficult. Deferring by a couple clock ticks I believe will have a relatively small impact on performance. Signed-off-by: John Heffner Signed-off-by: David S.

This proper layering is needed so that NFS can cleanly use the congestion functions, and so that CONFIG_BLOCK=n actually links.

That works fine; the only problem is mixing host- and network- endian values in the same objects. Network-endian equivalent would work just as fine; switch to it.
