[PATCH v3 0/3] selftests/resctrl: Simplify test cleanup functions

by Maciej Wieczor-Retman

Cleaning up after tests is implemented separately for individual tests and called at the end of each test execution. Since these functions are very similar and a more generalized test framework was introduced a function pointer in the resctrl_test struct can be used to reduce the amount of function calls. These functions are also all called in the ctrl-c handler because the handler isn't aware which test is currently running. Since the handler is implemented with a sigaction no function parameters can be passed there but information about what test is currently running can be passed with a global variable. Changelog v3: - Make current_test static. - Add callback NULL check to the ctrl-c handler. Changelog v2: - Make current_test a const pointer limited in scope to resctrl_val file. - Remove tests_cleanup from resctrl.h. - Cleanup 'goto out' path and labels in individual test functions.

[PATCH v5 00/12] RISCV: Add kvm Sstc timer selftests

by Haibo Xu

The RISC-V arch_timer selftests is used to validate Sstc timer functionality in a guest, which sets up periodic timer interrupts and check the basic interrupt status upon its receipt. This KVM selftests was ported from aarch64 arch_timer and tested with Linux v6.7-rc8 on a Qemu riscv64 virt machine. --- Changed since v4: * Rebased to Linux 6.7-rc8 * Added new patch(2/12) to clean up the data type in struct test_args * Re-ordered patch(11/11) in v4 to patch(3/12) * Changed the timer_err_margin_us type from int to uint32_t Haibo Xu (11): KVM: arm64: selftests: Data type cleanup for arch_timer test KVM: arm64: selftests: Enable tuning of error margin in arch_timer test KVM: arm64: selftests: Split arch_timer test code KVM: selftests: Add CONFIG_64BIT definition for the build tools: riscv: Add header file csr.h tools: riscv: Add header file vdso/processor.h KVM: riscv: selftests: Switch to use macro from csr.h KVM: riscv: selftests: Add exception handling support KVM: riscv: selftests: Add guest helper to get vcpu id KVM: riscv: selftests: Change vcpu_has_ext to a common function KVM: riscv: selftests: Add sstc timer test Paolo Bonzini (1): selftests/kvm: Fix issues with $(SPLIT_TESTS) tools/arch/riscv/include/asm/csr.h | 541 ++++++++++++++++++ tools/arch/riscv/include/asm/vdso/processor.h | 32 ++ tools/testing/selftests/kvm/Makefile | 27 +- .../selftests/kvm/aarch64/arch_timer.c | 295 +--------- tools/testing/selftests/kvm/arch_timer.c | 259 +++++++++ .../selftests/kvm/include/aarch64/processor.h | 4 - .../selftests/kvm/include/kvm_util_base.h | 9 + .../selftests/kvm/include/riscv/arch_timer.h | 71 +++ .../selftests/kvm/include/riscv/processor.h | 65 ++- .../testing/selftests/kvm/include/test_util.h | 2 + .../selftests/kvm/include/timer_test.h | 45 ++ .../selftests/kvm/lib/riscv/handlers.S | 101 ++++ .../selftests/kvm/lib/riscv/processor.c | 87 +++ .../testing/selftests/kvm/riscv/arch_timer.c | 111 ++++ .../selftests/kvm/riscv/get-reg-list.c | 11 +- 15 files changed, 1353 insertions(+), 307 deletions(-) create mode 100644 tools/arch/riscv/include/asm/csr.h create mode 100644 tools/arch/riscv/include/asm/vdso/processor.h create mode 100644 tools/testing/selftests/kvm/arch_timer.c create mode 100644 tools/testing/selftests/kvm/include/riscv/arch_timer.h create mode 100644 tools/testing/selftests/kvm/include/timer_test.h create mode 100644 tools/testing/selftests/kvm/lib/riscv/handlers.S create mode 100644 tools/testing/selftests/kvm/riscv/arch_timer.c -- 2.34.1

[PATCH RFC] kunit: tool: add 'mte=on' qemu arg on arm64

by Paul Heidekrüger

Hi! I was running some KASan tests with kunit.py recently and noticed that when KASan is run in hw tags mode, we manually have to add the required `mte=on` option to kunit_tool's qemu invocation, as the tests will otherwise crash. To make life easier, I was looking into ways for kunit.py to recognise when MTE support was required and set the option automatically. All solutions I could come up with for having kunit_tool conditionally pass `mte=on` to qemu, either entailed duplicate code or required parsing of kernel's config file again. I was working under the assumption that only after configuring the kernel we would know whether the 'mte=on' option was necessary, as CONFIG_ARM64_MTE is not visible before. Only afterwads did I realise that the qemu arm64 config that kunit_tool falls back on, uses the `virt` machine, which supports MTE in any case. So, could it be as easy as just adding the `mte=on` option to kunit_tool's arm64 config? Would this be a welcome addition? What do you think?
