Subject: [PATCH v4 00/12] RISCV: Add KVM_GET_REG_LIST API
Date: Fri, 23 Jun 2023 18:40:02 +0800 [thread overview]
Message-ID: <cover.1687515463.git.haibo1.xu@intel.com> (raw)
KVM_GET_REG_LIST will dump all register IDs that are available to
KVM_GET/SET_ONE_REG and It's very useful to identify some platform
regression issue during VM migration.
Patch 1-7 re-structured the get-reg-list test in aarch64 to make some
of the code as common test framework that can be shared by riscv.
Patch 8 move reject_set check logic to a function so as to check for
different errno for different registers.
Patch 9 change to do the get/set operation only on present-blessed list.
Patch 10 enabled the KVM_GET_REG_LIST API in riscv.
patch 11-12 added the corresponding kselftest for checking possible
register regressions.
The get-reg-list kvm selftest was ported from aarch64 and tested with
Linux 6.4-rc6 on a Qemu riscv64 virt machine.
---
Changed since v3:
* Rebase to Linux 6.4-rc6
* Address Andrew's suggestions and comments:
* Move reject_set check logic to a function
* Only do get/set tests on present blessed list
* Only enable ISA extension for the specified config
* For disable-not-allowed registers, move them to the filter-reg-list
Andrew Jones (7):
KVM: arm64: selftests: Replace str_with_index with strdup_printf
KVM: arm64: selftests: Drop SVE cap check in print_reg
KVM: arm64: selftests: Remove print_reg's dependency on vcpu_config
KVM: arm64: selftests: Rename vcpu_config and add to kvm_util.h
KVM: arm64: selftests: Delete core_reg_fixup
KVM: arm64: selftests: Split get-reg-list test code
KVM: arm64: selftests: Finish generalizing get-reg-list
