KVM: selftests: Use u32 instead of uint32_t

2026-04-20T21:54:16+00:00

Use u32 instead of uint32_t to make the KVM selftests code more concise and more similar to the kernel (since selftests are primarily developed by kernel developers). This commit was generated with the following command: git ls-files tools/testing/selftests/kvm | xargs sed -i 's/uint32_t/u32/g' Then by manually adjusting whitespace to make checkpatch.pl happy. No functional change intended. Signed-off-by: David Matlack Link: https://patch.msgid.link/20260420212004.3938325-7-seanjc@google.com Signed-off-by: Sean Christopherson

KVM: selftests: Use u64 instead of uint64_t

2026-04-20T21:54:16+00:00

Use u64 instead of uint64_t to make the KVM selftests code more concise and more similar to the kernel (since selftests are primarily developed by kernel developers). This commit was generated with the following command: git ls-files tools/testing/selftests/kvm | xargs sed -i 's/uint64_t/u64/g' Then by manually adjusting whitespace to make checkpatch.pl happy. Include in include/kvm_util_types.h, iinclude/test_util.h, and include/x86/pmu.h to pick up the tools-defined u64. Arguably, all headers (especially kvm_util_types.h) should have already been including stdint.h to get uint64_t from the libc headers, but the missing dependency only rears its head once KVM uses u64 instead of uint64_t. No functional change intended.

KVM: selftests: Use gpa_t instead of vm_paddr_t

2026-04-20T21:54:16+00:00

Replace all occurrences of vm_paddr_t with gpa_t to align with KVM code and with the conversion helpers (e.g. addr_hva2gpa()).

RISC-V: KVM: selftests: Fix firmware counter read in sbi_pmu_test

2026-03-27T14:32:11+00:00

The current sbi_pmu_test attempts to read firmware counters without configuring them first with SBI_EXT_PMU_COUNTER_CFG_MATCH. Previously this did not fail because KVM incorrectly allowed the read and accessed fw_event[] with an out-of-bounds index when the counter was unconfigured. After fixing that bug, the read now correctly returns SBI_ERR_INVALID_PARAM, causing the selftest to fail. Update the test to configure a firmware event before reading the counter. Also add a negative test to ensure that attempting to read an unconfigured firmware counter fails gracefully.

Merge tag 'kvm-riscv-6.20-1' of https://github.com/kvm-riscv/linux into HEAD

2026-02-11T17:45:00+00:00

KVM/riscv changes for 6.20 - Fixes for issues discoverd by KVM API fuzzing in kvm_riscv_aia_imsic_has_attr(), kvm_riscv_aia_imsic_rw_attr(), and kvm_riscv_vcpu_aia_imsic_update() - Allow Zalasr, Zilsd and Zclsd extensions for Guest/VM - Add riscv vm satp modes in KVM selftests - Transparent huge page support for G-stage - Adjust the number of available guest irq files based on MMIO register sizes in DeviceTree or ACPI

KVM: riscv: selftests: Add riscv vm satp modes

2026-02-06T13:35:23+00:00

Current vm modes cannot represent riscv guest modes precisely, here add all 9 combinations of P(56,40,41) x V(57,48,39). Also the default vm mode is detected on runtime instead of hardcoded one, which might not be supported on specific machine.

KVM: riscv: selftests: Decode stval to identify exact exception type

2025-05-21T04:04:37+00:00

Currently, the sbi_pmu_test continues if the exception type is illegal instruction because access to hpmcounter will generate that. However illegal instruction exception may occur due to the other reasons which should result in test assertion. Use the stval to decode the exact type of instructions and which csrs are being accessed if it is csr access instructions. Assert in all cases except if it is a csr access instructions that access valid PMU related registers. Take this opportunity to remove the CSR_CYCLEH reference as the test is compiled for RV64 only.
