tools headers: Update tools's copy of arm64/asm headers

2023-11-22T18:57:47+00:00

tldr; Just FYI, I'm carrying this on the perf tools tree. Full explanation: There used to be no copies, with tools/ code using kernel headers directly. From time to time tools/perf/ broke due to legitimate kernel hacking. At some point Linus complained about such direct usage. Then we adopted the current model. The way these headers are used in perf are not restricted to just including them to compile something. There are sometimes used in scripts that convert defines into string tables, etc, so some change may break one of these scripts, or new MSRs may use some different #define pattern, etc. E.g.: $ ls -1 tools/perf/trace/beauty/*.sh | head -5 tools/perf/trace/beauty/arch_errno_names.sh tools/perf/trace/beauty/drm_ioctl.sh tools/perf/trace/beauty/fadvise.sh tools/perf/trace/beauty/fsconfig.sh tools/perf/trace/beauty/fsmount.sh $ $ tools/perf/trace/beauty/fadvise.sh static const char *fadvise_advices[] = { [0] = "NORMAL", [1] = "RANDOM", [2] = "SEQUENTIAL", [3] = "WILLNEED", [4] = "DONTNEED", [5] = "NOREUSE", }; $ The tools/perf/check-headers.sh script, part of the tools/ build process, points out changes in the original files. So its important not to touch the copies in tools/ when doing changes in the original kernel headers, that will be done later, when check-headers.sh inform about the change to the perf tools hackers.

tools headers arm64: Update sysreg.h with kernel sources

2023-10-18T23:36:25+00:00

The users of sysreg.h (perf, KVM selftests) are now generating the necessary sysreg-defs.h; sync sysreg.h with the kernel sources and fix the KVM selftests that use macros which suffered a rename.

tools arm64: Import cputype.h

2022-03-26T13:53:45+00:00

Bring-in the kernel's arch/arm64/include/asm/cputype.h into tools/ for arm64 to make use of all the core-type definitions in perf. Replace sysreg.h with the version already imported into tools/. Committer notes: Added an entry to tools/perf/check-headers.sh, so that we get notified when the original file in the kernel sources gets modified. Tester notes: LGTM. I did the testing on both my x86 and Arm64 platforms, thanks for the fixing up.

tools: arm64: Import sysreg.h

2021-10-17T10:15:51+00:00

Bring-in the kernel's arch/arm64/include/asm/sysreg.h into tools/ for arm64 to make use of all the standard register definitions in consistence with the kernel. Make use of the register read/write definitions from sysreg.h, instead of the existing definitions. A syntax correction is needed for the files that use write_sysreg() to make it compliant with the new (kernel's) syntax.

tools: add smp_* barrier variants to include infrastructure

2019-04-11T21:45:50+00:00

Add the definition for smp_rmb(), smp_wmb(), and smp_mb() to the tools include infrastructure: this patch adds the implementation for x86-64 and arm64, and have it fall back as currently is for other archs which do not have it implemented at this point. The x86-64 one uses lock + add combination for smp_mb() with address below red zone. This is on top of 09d62154f613 ("tools, perf: add and use optimized ring_buffer_{read_head, write_tail} helpers"), which didn't touch smp_* barrier implementations. Magnus recently rightfully reported however that the latter on x86-64 still wrongly falls back to sfence, lfence and mfence respectively, thus fix that for applications under tools making use of these to avoid such ugly surprises. The main header under tools (include/asm/barrier.h) will in that case not select the fallback implementation.
