From fc9ef9118d8a6c6250273aae14b48dd8f91bee1f Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Mon, 3 Nov 2025 13:24:47 -0300 Subject: [PATCH] tools headers UAPI: Sync KVM's vmx.h header with the kernel sources to handle new exit reasons To pick the changes in: 885df2d2109a60f8 ("KVM: x86: Add support for RDMSR/WRMSRNS w/ immediate on Intel") c42856af8f70d983 ("KVM: TDX: Add a place holder for handler of TDX hypercalls (TDG.VP.VMCALL)") That makes 'perf kvm-stat' aware of these new TDCALL and MSR_{READ,WRITE}_IMM exit reasons, thus addressing the following perf build warning: Warning: Kernel ABI header differences: diff -u tools/arch/x86/include/uapi/asm/vmx.h arch/x86/include/uapi/asm/vmx.h Please see tools/include/uapi/README for further details.
