While debugging issues related to aarch64 only systems I ran into speedbumps due to the lack of detail in the results reported when the guest register read and reset value preservation tests were run, they generated an immediately fatal assert without indicating which register was being tested. Update these tests to non-fatally report a standard kselftest result per register, making it much easier to see what the problem being reported is.
A similar issue exists with the validation of the individual bitfields in registers due to the use of immediately fatal asserts. Update those asserts to be standard kselftest reports. Signed-off-by: Mark Brown <[email protected]> --- Changes in v6: - Rebase onto v7.2-rc3. - Drop changes to handling of aarch32 related registers on 64 bit only systems, an in kernel solution is preferred for those. - Use a define to count the non-test_regs registers. - Link to v5: https://patch.msgid.link/20260317-kvm-arm64-set-id-regs-aarch64-v5-0-a60f2b956...@kernel.org Changes in v5: - Rebase onto v7.0-rc1. - Link to v4: https://patch.msgid.link/20260106-kvm-arm64-set-id-regs-aarch64-v4-0-c7ef4551a...@kernel.org Changes in v4: - Correct check for 32 bit ID registers. - Link to v3: https://patch.msgid.link/20251219-kvm-arm64-set-id-regs-aarch64-v3-0-bfa474ec3...@kernel.org Changes in v3: - Rebase onto v6.19-rc1. - Link to v2: https://patch.msgid.link/20251114-kvm-arm64-set-id-regs-aarch64-v2-0-672f214f4...@kernel.org Changes in v2: - Add a fix for spurious failures with 64 bit only guests. - Link to v1: https://patch.msgid.link/20251030-kvm-arm64-set-id-regs-aarch64-v1-0-96fe0d2b1...@kernel.org --- Mark Brown (3): KVM: selftests: arm64: Report set_id_reg reads of test registers as tests KVM: selftests: arm64: Report register reset tests individually KVM: selftests: arm64: Make set_id_regs bitfield validatity checks non-fatal tools/testing/selftests/kvm/arm64/set_id_regs.c | 121 ++++++++++++++++++------ 1 file changed, 91 insertions(+), 30 deletions(-) --- base-commit: a13c140cc289c0b7b3770bce5b3ad42ab35074aa change-id: 20251028-kvm-arm64-set-id-regs-aarch64-ebb77969401c Best regards, -- Mark Brown <[email protected]>
