Subject: [PATCH v5 00/13] RISCV: Add KVM_GET_REG_LIST API
Date:   Sat,  1 Jul 2023 21:42:48 +0800

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 move finalize_vcpu back to run_test so that riscv can implement
its specific operation.
Patch 10 change to do the get/set operation only on present-blessed list.
Patch 11 add the skip_set facilities so that riscv can skip set operation
on some registers.
Patch 12 enabled the KVM_GET_REG_LIST API in riscv.
patch 13 added the corresponding kselftest for checking possible
register regressions.

The get-reg-list kvm selftest was ported from aarch64 and tested with
Linux v6.4 on a Qemu riscv64 virt machine.

Changed since v4:
  * Rebase to v6.4
  * Address Andrew's suggestions and comments:
      Added skip_set concept
      Updated errno check logic
      Modified finalize_vcpu as weak function

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

Haibo Xu (6):
  KVM: arm64: selftests: Move reject_set check logic to a function
