The writable ID register test depends on the latest system register definitions, which cannot be trivially added to tools. In order to keep a single copy of sysreg gunk in tools all users (KVM selftests, perf) need to be updated to generate headers at build time. Tested arm64 and x86 builds of both KVM selftests and perf tool. v1 -> v2: - Use the sysreg definition generation script instead of copying the output (broonie) - Use a common Makefile for both KVM selftests as well as perf - Include the KVM selftest responsible for the change v1: https://lore.kernel.org/kvmarm/20231005180325.525236-1-oliver.upton@xxxxxxxxx/ Jing Zhang (2): tools headers arm64: Update sysreg.h with kernel sources KVM: arm64: selftests: Test for setting ID register from usersapce Oliver Upton (3): tools headers arm64: Copy sysreg-defs generation from kernel source perf build: Generate arm64's sysreg-defs.h and add to include path KVM: selftests: Generate sysreg-defs.h and add to include path tools/arch/arm64/include/.gitignore | 1 + tools/arch/arm64/include/asm/gpr-num.h | 26 + tools/arch/arm64/include/asm/sysreg.h | 839 ++---- tools/arch/arm64/tools/Makefile | 38 + tools/arch/arm64/tools/gen-sysreg.awk | 336 +++ tools/arch/arm64/tools/sysreg | 2497 +++++++++++++++++ tools/perf/Makefile.perf | 15 +- tools/perf/check-headers.sh | 4 + tools/perf/util/Build | 2 +- tools/testing/selftests/kvm/Makefile | 24 +- .../selftests/kvm/aarch64/aarch32_id_regs.c | 4 +- .../selftests/kvm/aarch64/debug-exceptions.c | 12 +- .../selftests/kvm/aarch64/page_fault_test.c | 6 +- .../selftests/kvm/aarch64/set_id_regs.c | 479 ++++ .../selftests/kvm/lib/aarch64/processor.c | 6 +- 15 files changed, 3622 insertions(+), 667 deletions(-) create mode 100644 tools/arch/arm64/include/.gitignore create mode 100644 tools/arch/arm64/include/asm/gpr-num.h create mode 100644 tools/arch/arm64/tools/Makefile create mode 100755 tools/arch/arm64/tools/gen-sysreg.awk create mode 100644 tools/arch/arm64/tools/sysreg create mode 100644 tools/testing/selftests/kvm/aarch64/set_id_regs.c base-commit: dafa493dd01d5992f1cb70b08d1741c3ab99e04a -- 2.42.0.609.gbb76f46606-goog
