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 <adrian.hunter@intel.com> Cc: Alexander Yarygin <yarygin@linux.vnet.ibm.com> Cc: Borislav Petkov <bp@suse.de> Cc: Christian Borntraeger <borntraeger@de.ibm.com> Cc: Cornelia Huck <cornelia.huck@de.ibm.com> Cc: David Ahern <dsahern@gmail.com> Cc: Ian Rogers <irogers@google.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Joerg Roedel <jroedel@suse.de> Cc: Namhyung Kim <namhyung@kernel.org> Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> |

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
