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.

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()).

This commit was generated with the following command:

  git ls-files tools/testing/selftests/kvm | xargs sed -i 's/vm_paddr_/gpa_/g'

Then by manually adjusting whitespace to make checkpatch.pl happy.

No functional change intended.

KVM: selftests: Use gva_t instead of vm_vaddr_t

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

Replace all occurrences of vm_vaddr_t with gva_t to align with KVM code
and with the conversion helpers (e.g. addr_gva2hva()).

This commit was generated with the following command:

  git ls-files tools/testing/selftests/kvm | xargs sed -i 's/vm_vaddr_/gva_/g'

Then by manually adjusting whitespace to make checkpatch.pl happy, and
dropping renames of functions that allocate memory within a given VM.

No functional change intended.

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.
