2022-10-02kbuild: use obj-y instead extra-y for objects placed at the headMasahiro Yamada
The objects placed at the head of vmlinux need special treatments: - arch/$(SRCARCH)/Makefile adds them to head-y in order to place them before other archives in the linker command line. - arch/$(SRCARCH)/kernel/Makefile adds them to extra-y instead of obj-y to avoid them going into built-in.a. This commit gets rid of the latter. Create vmlinux.a to collect all the objects that are unconditionally linked to vmlinux. The objects listed in head-y are moved to the head of vmlinux.a by using 'ar m'. With this, arch/$(SRCARCH)/kernel/Makefile can consistently use obj-y for builtin objects. There is no *.o that is directly linked to vmlinux. Drop unneeded code in scripts/clang-tools/gen_compile_commands.py. $(AR) mPi needs 'T' to workaround the llvm-ar bug.

Implement the CPU vulnerabilty show functions for meltdown, spectre_v1 and spectre_v2 on Alpha. Tests on XP1000 (EV67/667MHz) and ES45 (EV68CB/1.25GHz) show them to be vulnerable to Meltdown and Spectre V1. In the case of Meltdown I saw a 1 to 2% success rate in reading bytes on the XP1000 and 50 to 60% success rate on the ES45. (This compares to 99.97% success reported for Intel CPUs.) Report EV6 and later CPUs as vulnerable. Tests on PWS600au (EV56/600MHz) for Spectre V1 attack were unsuccessful (though I did not try particularly hard) so mark EV4 through to EV56 as not vulnerable.

2017-11-02License cleanup: add SPDX GPL-2.0 license identifier to files with no licenseGreg Kroah-Hartman
Many source files in the tree are missing licensing information, which makes it harder for compliance tools to determine the correct license. By default all files without license information are under the default license of the kernel, which is GPL version 2. Update the files which contain no license information with the 'GPL-2.0' SPDX license identifier. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. This patch is based on work done by Thomas Gleixner and Kate Stewart and Philippe Ombredanne. How this work was done: Patches were generated and checked against linux-4.14-rc6 for a subset of the use cases: - file had no licensing information it it. - file was a */uapi/* one with no licensing information in it, - file was a */uapi/* one with existing licensing information, Further patches will be generated in subsequent months to fix up cases where non-standard license headers were used, and references to license had to be inferred by heuristics based on keywords. The analysis to determine which SPDX License Identifier to be applied to a file was done in a spreadsheet of side by side results from of the output of two independent scanners (ScanCode & Windriver) producing SPDX tag:value files created by Philippe Ombredanne. Philippe prepared the base worksheet, and did an initial spot review of a few 1000 files. The 4.13 kernel was the starting point of the analysis with 60,537 files assessed. Kate Stewart did a file by file comparison of the scanner results in the spreadsheet to determine which SPDX license identifier(s) to be applied to the file. She confirmed any determination that was not immediately clear with lawyers working with the Linux Foundation. Criteria used to select files for SPDX license identifier tagging was: - Files considered eligible had to be source code files. - Make and config files were included as candidates if they contained >5 lines of source - File already had some variant of a license header in it (even if <5 lines). All documentation files were explicitly excluded. The following heuristics were used to determine which SPDX license identifiers to apply. - when both scanners couldn't find any license traces, file was considered to have no license information in it, and the top level COPYING file license applied. For non */uapi/* files that summary was: SPDX license identifier # files ---------------------------------------------------|------- GPL-2.0 11139 and resulted in the first patch in this series. If that file was a */uapi/* path one, it was "GPL-2.0 WITH Linux-syscall-note" otherwise it was "GPL-2.0". Results of that was: SPDX license identifier # files ---------------------------------------------------|------- GPL-2.0 WITH Linux-syscall-note 930 and resulted in the second patch in this series. - if a file had some form of licensing information in it, and was one of the */uapi/* ones, it was denoted with the Linux-syscall-note if any GPL family license was found in the file or had no licensing in it (per prior point). Results summary: SPDX license identifier # files ---------------------------------------------------|------ GPL-2.0 WITH Linux-syscall-note 270 GPL-2.0+ WITH Linux-syscall-note 169 ((GPL-2.0 WITH Linux-syscall-note) OR BSD-2-Clause) 21 ((GPL-2.0 WITH Linux-syscall-note) OR BSD-3-Clause) 17 LGPL-2.1+ WITH Linux-syscall-note 15 GPL-1.0+ WITH Linux-syscall-note 14 ((GPL-2.0+ WITH Linux-syscall-note) OR BSD-3-Clause) 5 LGPL-2.0+ WITH Linux-syscall-note 4 LGPL-2.1 WITH Linux-syscall-note 3 ((GPL-2.0 WITH Linux-syscall-note) OR MIT) 3 ((GPL-2.0 WITH Linux-syscall-note) AND MIT) 1 and that resulted in the third patch in this series. - when the two scanners agreed on the detected license(s), that became the concluded license(s). - when there was disagreement between the two scanners (one detected a license but the other didn't, or they both detected different licenses) a manual inspection of the file occurred. - In most cases a manual inspection of the information in the file resulted in a clear resolution of the license that should apply (and which scanner probably needed to revisit its heuristics). - When it was not immediately clear, the license identifier was confirmed with lawyers working with the Linux Foundation. - If there was any question as to the appropriate license identifier, the file was flagged for further research and to be revisited later in time. In total, over 70 hours of logged manual review was done on the spreadsheet to determine the SPDX license identifiers to apply to the source files by Kate, Philippe, Thomas and, in some cases, confirmation by lawyers working with the Linux Foundation. Kate also obtained a third independent scan of the 4.13 code base from FOSSology, and compared selected files where the other two scanners disagreed against that SPDX file, to see if there was new insights. The Windriver scanner is based on an older version of FOSSology in part, so they are related. Thomas did random spot checks in about 500 files from the spreadsheets for the uapi headers and agreed with SPDX license identifier in the files he inspected. For the non-uapi files Thomas did random spot checks in about 15000 files. In initial set of patches against 4.14-rc6, 3 files were found to have copy/paste license identifier errors, and have been fixed to reflect the correct identifier. Additionally Philippe spent 10 hours this week doing a detailed manual inspection and review of the 12,461 patched files from the initial patch version early this week with: - a full scancode scan run, collecting the matched texts, detected license ids and scores - reviewing anything where there was a license detected (about 500+ files) to ensure that the applied SPDX license was correct - reviewing anything where there was no detection but the patch license was not GPL-2.0 WITH Linux-syscall-note to ensure that the applied SPDX license was correct This produced a worksheet with 20 files needing minor correction. This worksheet was then exported into 3 different .csv files for the different types of files to be modified. These .csv files were then reviewed by Greg. Thomas wrote a script to parse the csv files and add the proper SPDX tag to the file, in the format that the file expected. This script was further refined by Greg based on the output to detect more types of files automatically and to distinguish between header and source .c files (which need different comment types.) Finally Greg ran the script using the .csv files to generate the patches.

2013-11-16alpha: Reorganize rtc handlingRichard Henderson
Discontinue use of GENERIC_CMOS_UPDATE; rely on the RTC subsystem. The marvel platform requires that the rtc only be touched from the boot cpu. This had been partially implemented with hooks for get/set_rtc_time, but read/update_persistent_clock were not handled. Move the hooks from the machine_vec to a special rtc_class_ops struct. We had read_persistent_clock managing the epoch against which the rtc hw is based, but this didn't apply to get_rtc_time or set_rtc_time. This resulted in incorrect values when hwclock(8) gets involved. Allow the epoch to be set from the kernel command-line, overriding the autodetection, which is doomed to fail in 2020. Further, by implementing the rtc ioctl function, we can expose this epoch to userland. Elide the alarm functions that RTC_DRV_CMOS implements. This was highly questionable on Alpha, since the interrupt is used by the system timer. Signed-off-by: Richard Henderson <rth@twiddle.net>

2009-05-02alpha: binfmt_aout fixIvan Kokshaysky
This fixes the problem introduced by commit 3bfacef412 (get rid of special-casing the /sbin/loader on alpha): osf/1 ecoff binary segfaults when binfmt_aout built as module. That happens because aout binary handler gets on the top of the binfmt list due to late registration, and kernel attempts to execute the binary without preparatory work that must be done by binfmt_loader. Fixed by changing the registration order of the default binfmt handlers using list_add_tail() and introducing insert_binfmt() function which places new handler on the top of the binfmt list. This might be generally useful for installing arch-specific frontends for default handlers or just for overriding them.

2009-03-19PCI/alpha: pci sysfs resourcesIvan Kokshaysky
This closes http://bugzilla.kernel.org/show_bug.cgi?id=10893 which is a showstopper for X development on alpha. The generic HAVE_PCI_MMAP code (drivers/pci-sysfs.c) is not very useful since we have to deal with three different types of MMIO address spaces: sparse and dense mappings for old ev4/ev5 machines and "normal" 1:1 MMIO space (bwx) for ev56 and later. Also "write combine" mappings are meaningless on alpha - roughly speaking, alpha does write combining, IO reordering and other optimizations by default, unless user splits IO accesses with memory barriers. I think the cleanest way to deal with resource files on alpha is to convert the default no-op pci_create_resource_files() and pci_remove_resource_files() for !HAVE_PCI_MMAP case into __weak functions and override them with alpha specific ones. Another alpha hook is needed for "legacy_" resource files to handle sparse addressing (pci_adjust_legacy_attr). With the "standard" resourceN files on ev56/ev6 libpciaccess works "out of the box". Handling of resourceN_sparse/resourceN_dense files on older machines obviously requires some userland work. Sparse/dense stuff has been tested on sx164 (pca56/pyxis, normally uses bwx IO) with the kernel hacked into "cia compatible" mode.

2003-08-05kbuild: Move generation of vmlinux.lds.s into arch/.../kernelKai Germaschewski
Currently, vmlinux.lds.s is generated by the top-level Makefile. Unfortunately, this causes the automatic CONFIG dependencies to not work correctly, the reason being that make caches the timestamps of include/config/* so even after split-include updated the timestamps, make still uses the cached stamps to decide whether to rebuild vmlinux.lds.s. The simple fix is to move generation of vmlinux.lds.s into the arch/$(ARCH)/kernel subdirectories, where we build other files for the final link (like head.o) anyway. This also means some special code in the top-level Makefile for preprocessing can go away, since we now just use the standard rules during the recursive phase. This patches fixes up all archs for this change (untested).

2003-02-22[PATCH] Alpha CFLAGS fixSam Ravnborg
Hi Richard. I noticed you have set -Werror in all alpha architecture specific makefiles - good initiative. I wish we could do that in general. But the correct way to alter CFLAGS in kbuild makefiles is to use EXTRA_CFLAGS. The following patch fixes this. You could argue that this is a stylistic issue, but in this way you follow Documentation/kbuild/makefiles.txt I stumbled over: EXTRA_AFLAGS := $(CFLAGS) I could not realise the purpose with this assignment, and I noticed that it did not include -Werror, becuse you did hat assignment in the following line. Wanted to inform you about it but I see no problem. It is just that I did not understand it. In math-emu I see this: EXTRA_CFLAGS := -Iinclude/math-emu -w Grepping the src I see no reason to have the -Iinclude/math-emu Relevant files are prefixed with math-emu (soft-fp, single, double) I did not fix it, because I cannot compile alpha.

2003-01-19[ALPHA] New SRM console driver.Richard Henderson
From Jeff Wiedemeier: How about this.. This version no longer piggy backs on ttyS0 (it actually doesn't touch any files outside arch/alpha/kernel at all). It does use a dynamic major for the tty piece of the driver. From userspace, /dev/console is ok for most uses, but because of the 'noctty = 1' at tty_tio.c:1329 (in the IS_SYSCONS_DEV section) using /dev/console cannot result in a controlling tty so some things, like 'resize' and bash job control don't work. For those uses, however, it's easy enough to parse /proc/devices on the way up to get the major number and create the specific device for the tty side of the driver. I made a distinction in kernel options as well. "srmcons" specifically requests the early prints (as before) and "console=srm" requests the full driver, including the early prints. The two options can be combined with "console=srm" behavior resulting. The other change is that if "console=srm" is specified, I don't unregister_srm_console before console_init any more - that only happens in the "srmcons" case. That way preferred console selection remains stable and "console=srm" doesn't result in the early messages being repeated when the driver re-registers. The use of "srmcons_allowed" is also eliminated due to the "srmcons" vs. "console=srm" distinction.

2002-11-02[PATCH] alpha: common ev6/ev7 machine check handlerIvan Kokshaysky
Here is new ev6/ev7 machine check parser, which is a part of Jeff's titan/marvel patchset. Instead of fixing nautilus machine check handler, I've converted it to use this new code. Works fine. Also, the CONFIG_VERBOSE_MCHECK is good for cia/pyxis - the detailed error reporting is completely useless unless you have faulty CPU or RAM. Ivan.
