Subject: [PATCH 1/1 fyi] tools arch x86: Sync the msr-index.h copy with the kernel sources
Date: Thu, 12 Jun 2025 18:02:10 -0300 [thread overview]
Message-ID: <aEtAUg83OQGx8Kay@x1> (raw)
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.
See further details at:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/tools/include/uapi/README
To pick up the changes from these csets:
159013a7ca18c271 ("x86/its: Enumerate Indirect Target Selection (ITS) bug")
f4138de5e41fae1a ("x86/msr: Standardize on u64 in <asm/msr-index.h>")
ec980e4facef8110 ("perf/x86/intel: Support auto counter reload")
That cause no changes to tooling as it doesn't include a new MSR to be
captured by the tools/perf/trace/beauty/tracepoints/x86_msr.sh script.
Just silences this perf build warning:
Warning: Kernel ABI header differences:
diff -u tools/arch/x86/include/asm/msr-index.h arch/x86/include/asm/msr-index.h
