Subject: [PATCH 1/1 fyi] tools headers UAPI: Sync kvm headers with the kernel sources
Date: Tue, 22 Oct 2024 17:40:48 -0300	[thread overview]
Message-ID: <ZxgN0O02YrAJ2qIC@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 the changes in:

  aa8d1f48d353b046 ("KVM: x86/mmu: Introduce a quirk to control memslot zap behavior")

That don't change functionality in tools/perf, as no new ioctl is added
for the 'perf trace' scripts to harvest.

This addresses these perf build warnings:

  Warning: Kernel ABI header differences:
    diff -u tools/arch/x86/include/uapi/asm/kvm.h arch/x86/include/uapi/asm/kvm.h

Please see tools/include/uapi/README for further details.
