tools headers: Remove unused kvm_perf.h copies

2025-09-11T19:57:59+00:00

These have been unused since commit 162607ea20fa ("perf kvm/{x86,s390}: Remove dependency on uapi/kvm_perf.h") in favour of dynamic discovery. Remove the unused headers to reduce consistency checking overhead and noise.

KVM: s390: selftests: Add regression tests for PFCR subfunctions

2024-11-11T12:15:44+00:00

Check if the PFCR query reported in userspace coincides with the kernel reported function list. Right now we don't mask the functions in the kernel so they have to be the same.

tools headers: Update tools's copy of s390/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 kvm headers: Update KVM headers from the kernel sources

2020-11-03T11:46:30+00:00

Some should cause changes in tooling, like the one adding LAST_EXCP, but the way it is structured end up not making that happen. The new SVM_EXIT_INVPCID should get used by arch/x86/util/kvm-stat.c, in the svm_exit_reasons table. The tools/perf/trace/beauty part has scripts to catch changes and automagically create tables, like tools/perf/trace/beauty/kvm_ioctl.sh, but changes are needed to make tools/perf/arch/x86/util/kvm-stat.c catch those automatically. These were handled by the existing scripts: $ tools/perf/trace/beauty/kvm_ioctl.sh > before $ cp include/uapi/linux/kvm.h tools/include/uapi/linux/kvm.h $ tools/perf/trace/beauty/kvm_ioctl.sh > after $ diff -u before after --- before 2020-11-03 08:43:52.910728608 -0300 +++ after 2020-11-03 08:44:04.273959984 -0300 @@ -89,6 +89,7 @@ [0xbf] = "SET_NESTED_STATE", [0xc0] = "CLEAR_DIRTY_LOG", [0xc1] = "GET_SUPPORTED_HV_CPUID", + [0xc6] = "X86_SET_MSR_FILTER", [0xe0] = "CREATE_DEVICE", [0xe1] = "SET_DEVICE_ATTR", [0xe2] = "GET_DEVICE_ATTR", $ $ tools/perf/trace/beauty/vhost_virtio_ioctl.sh > before $ cp include/uapi/linux/vhost.h tools/include/uapi/linux/vhost.h $ $ tools/perf/trace/beauty/vhost_virtio_ioctl.sh > after $ diff -u before after --- before 2020-11-03 08:45:55.522225198 -0300 +++ after 2020-11-03 08:46:12.881578666 -0300 @@ -37,4 +37,5 @@ [0x71] = "VDPA_GET_STATUS", [0x73] = "VDPA_GET_CONFIG", [0x76] = "VDPA_GET_VRING_NUM", + [0x78] = "VDPA_GET_IOVA_RANGE", }; $ This addresses these perf build warnings: Warning: Kernel ABI header at 'tools/arch/arm64/include/uapi/asm/kvm.h' differs from latest version at 'arch/arm64/include/uapi/asm/kvm.h' diff -u tools/arch/arm64/include/uapi/asm/kvm.h arch/arm64/include/uapi/asm/kvm.h Warning: Kernel ABI header at 'tools/arch/s390/include/uapi/asm/sie.h' differs from latest version at 'arch/s390/include/uapi/asm/sie.h' diff -u tools/arch/s390/include/uapi/asm/sie.h arch/s390/include/uapi/asm/sie.h Warning: Kernel ABI header at 'tools/arch/x86/include/uapi/asm/kvm.h' differs from latest version at 'arch/x86/include/uapi/asm/kvm.h' diff -u tools/arch/x86/include/uapi/asm/kvm.h arch/x86/include/uapi/asm/kvm.h Warning: Kernel ABI header at 'tools/arch/x86/include/uapi/asm/svm.h' differs from latest version at 'arch/x86/include/uapi/asm/svm.h' diff -u tools/arch/x86/include/uapi/asm/svm.h arch/x86/include/uapi/asm/svm.h Warning: Kernel ABI header at 'tools/include/uapi/linux/kvm.h' differs from latest version at 'include/uapi/linux/kvm.h' diff -u tools/include/uapi/linux/kvm.h include/uapi/linux/kvm.h Warning: Kernel ABI header at 'tools/include/uapi/linux/vhost.h' differs from latest version at 'include/uapi/linux/vhost.h' diff -u tools/include/uapi/linux/vhost.h include/uapi/linux/vhost.h Cc: Adrian Hunter Cc: Alexander Yarygin Cc: Borislav Petkov Cc: Christian Borntraeger Cc: Cornelia Huck Cc: David Ahern Cc: Ian Rogers Cc: Jiri Olsa Cc: Joerg Roedel Cc: Namhyung Kim Signed-off-by: Arnaldo Carvalho de Melo
