[PATCH] kunit: tool: add test counts to JSON output

by Rae Moar

Add the test counts to the JSON output from kunit.py. For example: ... "git_branch": "kselftest", "misc": { "tests": 2, "passed": 1. "failed": 1, "crashed": 0, "skipped": 0, "errors": 0, } ... To output the JSON using the following command: ./tools/testing/kunit/kunit.py run example --json This has been requested by KUnit users. The counts are in a "misc" field because the JSON output needs to be compliant with the KCIDB submission guide. There are no counts fields but there is a "misc" field in the guide.

[PATCH v12 0/5] KVM: selftests: Add LoongArch support

by Bibo Mao

This patchset adds KVM selftests for LoongArch system, currently only some common test cases are supported and pass to run. These test cases are listed as following: coalesced_io_test demand_paging_test dirty_log_perf_test dirty_log_test guest_print_test hardware_disable_test kvm_binary_stats_test kvm_create_max_vcpus kvm_page_table_test memslot_modification_stress_test memslot_perf_test set_memory_region_test --- Changes in v12: 1. Replace vcpu_set_reg() with __vcpu_set_reg() in loongarch_set_csr() 2. Remove duplicated test case including in Makefile.kvm 3. Fix one issue reported by checkpatch Changes in v11: 1. Fix a typo issue in notes of patch 2, it is kvm_util_arch.h rather than kvm_util_base.h Changes in v10: 1. Add PS_64K and remove PS_8K in file include/loongarch/processor.h 2. Fix a typo issue in file lib/loongarch/processor.c 3. Update file MAINTAINERS about LoongArch KVM selftests Changes in v9: 1. Add vm mode VM_MODE_P47V47_16K, LoongArch VM uses this mode by default, rather than VM_MODE_P36V47_16K. 2. Refresh some spelling issues in changelog. Changes in v8: 1. Porting patch based on the latest version. 2. For macro PC_OFFSET_EXREGS, offsetof() method is used for C header file, still hardcoded definition for assemble language. Changes in v7: 1. Refine code to add LoongArch support in test case set_memory_region_test. Changes in v6: 1. Refresh the patch based on latest kernel 6.8-rc1, add LoongArch support about testcase set_memory_region_test. 2. Add hardware_disable_test test case. 3. Drop modification about macro DEFAULT_GUEST_TEST_MEM, it is problem of LoongArch binutils, this issue is raised to LoongArch binutils owners. Changes in v5: 1. In LoongArch kvm self tests, the DEFAULT_GUEST_TEST_MEM could be 0x130000000, it is different from the default value in memstress.h. So we Move the definition of DEFAULT_GUEST_TEST_MEM into LoongArch ucall.h, and add 'ifndef' condition for DEFAULT_GUEST_TEST_MEM in memstress.h. Changes in v4: 1. Remove the based-on flag, as the LoongArch KVM patch series have been accepted by Linux kernel, so this can be applied directly in kernel. Changes in v3: 1. Improve implementation of LoongArch VM page walk. 2. Add exception handler for LoongArch. 3. Add dirty_log_test, dirty_log_perf_test, guest_print_test test cases for LoongArch. 4. Add __ASSEMBLER__ macro to distinguish asm file and c file. 5. Move ucall_arch_do_ucall to the header file and make it as static inline to avoid function calls. 6. Change the DEFAULT_GUEST_TEST_MEM base addr for LoongArch. Changes in v2: 1. We should use ".balign 4096" to align the assemble code with 4K in exception.S instead of "align 12". 2. LoongArch only supports 3 or 4 levels page tables, so we remove the hanlders for 2-levels page table. 3. Remove the DEFAULT_LOONGARCH_GUEST_STACK_VADDR_MIN and use the common DEFAULT_GUEST_STACK_VADDR_MIN to allocate stack memory in guest. 4. Reorganize the test cases supported by LoongArch. 5. Fix some code comments. 6. Add kvm_binary_stats_test test case into LoongArch KVM selftests. --- Bibo Mao (5): KVM: selftests: Add VM_MODE_P47V47_16K VM mode KVM: selftests: Add KVM selftests header files for LoongArch KVM: selftests: Add core KVM selftests support for LoongArch KVM: selftests: Add ucall test support for LoongArch KVM: selftests: Add supported test cases for LoongArch MAINTAINERS | 2 + tools/testing/selftests/kvm/Makefile | 2 +- tools/testing/selftests/kvm/Makefile.kvm | 17 + .../testing/selftests/kvm/include/kvm_util.h | 6 + .../kvm/include/loongarch/kvm_util_arch.h | 7 + .../kvm/include/loongarch/processor.h | 141 +++++++ .../selftests/kvm/include/loongarch/ucall.h | 20 + tools/testing/selftests/kvm/lib/kvm_util.c | 3 + .../selftests/kvm/lib/loongarch/exception.S | 59 +++ .../selftests/kvm/lib/loongarch/processor.c | 347 ++++++++++++++++++ .../selftests/kvm/lib/loongarch/ucall.c | 38 ++ .../selftests/kvm/set_memory_region_test.c | 2 +- 12 files changed, 642 insertions(+), 2 deletions(-) create mode 100644 tools/testing/selftests/kvm/include/loongarch/kvm_util_arch.h create mode 100644 tools/testing/selftests/kvm/include/loongarch/processor.h create mode 100644 tools/testing/selftests/kvm/include/loongarch/ucall.h create mode 100644 tools/testing/selftests/kvm/lib/loongarch/exception.S create mode 100644 tools/testing/selftests/kvm/lib/loongarch/processor.c create mode 100644 tools/testing/selftests/kvm/lib/loongarch/ucall.c base-commit: a5806cd506af5a7c19bcd596e4708b5c464bfd21 -- 2.39.3

[PATCH v3] KVM: SEV: Disable SEV-SNP support on initialization failure

by Ashish Kalra

From: Ashish Kalra <ashish.kalra(a)amd.com> During platform init, SNP initialization may fail for several reasons, such as firmware command failures and incompatible versions. However, the KVM capability may continue to advertise support for it. The platform may have SNP enabled but if SNP_INIT fails then SNP is not supported by KVM. During KVM module initialization query the SNP platform status to obtain the SNP initialization state and use it as an additional condition to determine support for SEV-SNP.
