ssb: Handle alternate SSPROM location

2010-08-10T17:54:18Z

commit 9d1ac34ec3a67713308ae0883c3359c557f14d17 upstream. In kernel Bugzilla #15825 (2 users), in a wireless mailing list thread (http://lists.infradead.org/pipermail/b43-dev/2010-May/000124.html), and on a netbook owned by John Linville (http://marc.info/?l=linux-wireless&m=127230751408818&w=4), there are reports of ssb failing to detect an SPROM at the normal location. After studying the MMIO trace dump for the Broadcom wl driver, it was determined that the affected boxes had a relocated SPROM. This patch fixes all systems that have reported this problem.

ssb: fix NULL ptr deref when pcihost_wrapper is used

2010-08-10T17:54:18Z

commit da1fdb02d9200ff28b6f3a380d21930335fe5429 upstream. Ethernet driver b44 does register ssb by it's pcihost_wrapper and doesn't set ssb_chipcommon.

ssb: Look for SPROM at different offset on higher rev CC

2010-08-10T17:54:17Z

commit ea2db495f92ad2cf3301623e60cb95b4062bc484 upstream. Our offset handling becomes even a little more hackish now. For some reason I do not understand all offsets as inrelative. It assumes base offset is 0x1000 but it will work for now as we make offsets relative anyway by removing base 0x1000. Should be cleaner however. Signed-off-by: Rafał Miłecki Signed-off-by: John W.

ssb: do not read SPROM if it does not exist

2010-08-10T17:54:17Z

commit d53cdbb94a52a920d5420ed64d986c3523a56743 upstream. Attempting to read registers that don't exist on the SSB bus can cause hangs on some boxes. At least some b43 devices are 'in the wild' that don't have SPROMs at all. When the SSB bus support loads, it attempts to read these (non-existant) SPROMs and causes hard hangs on the box -- no console output, etc. This patch adds some intelligence to determine whether or not the SPROM is present before attempting to read it. This avoids those hard hangs on those devices with no SPROM attached to their SSB bus. The SSB-attached devices (e.g. b43, et al.) won't work, but at least the box will survive to test further patches. :-) Signed-off-by: John W.

Revert "ssb: Handle Netbook devices where the SPROM address is changed"

ssb: Handle Netbook devices where the SPROM address is changed

2010-08-02T17:29:20Z

For some Netbook computers with Broadcom BCM4312 wireless interfaces, the SPROM has been moved to a new location. When the ssb driver tries to read the old location, the systems hangs when trying to read a non-existent location. Such freezes are particularly bad as they do not log the failure. This patch is modified from commit da1fdb02d9200ff28b6f3a380d21930335fe5429 with some pieces from other mainline changes so that it can be applied to stable 2.6.34.Y.

MIPS: Fix SSB PCIcore IO resource management

2010-04-12T16:26:14Z

The SSB PCIcore code reused the IO resource fixup code from the original 2.4.x Broadcom patch for BCM47xx based devices, which was a quick hack for doing PCI IO resource configuration back then (the boot loader doesn't configure PCI devices on this platform). However, this code is no longer necessary since the kernel now can do PCI resource management fine all by itself, so remove the old code. When removing the code, it becomes obvious that the mem_offset setting in the PCIcore driver was wrong, however this was masked by the fixup code before, except in a few cases involving yenta_socket. For BCM47xx, the correct offset is 0, and since this is the only device using PCIcore in host mode, the offset can simply be removed unconditionally.

include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h

2010-03-30T13:02:32Z

percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.
