Subject: [PATCH v2 2/3] KVM: selftests: Update aarch64 get-reg-list blessed list
Date: Mon,  2 Nov 2020 20:02:52 +0100	[thread overview]
Message-ID: <20201102190253.50575-3-drjones@redhat.com> (raw)
In-Reply-To: <20201102190253.50575-1-drjones@redhat.com>

The new registers come from the following commits:

commit 99adb567632b ("KVM: arm/arm64: Add save/restore support for
firmware workaround state")

commit c773ae2b3476 ("KVM: arm64: Save/Restore guest DISR_EL1")

commit 03fdfb269009 ("KVM: arm64: Don't write junk to sysregs on reset")

The last commit, which adds ARM64_SYS_REG(3, 3, 9, 12, 0) (PMCR_EL0),
and was committed for v5.3, doesn't indicate in its commit message that
enumerating it for save/restore was the plan. It's a good idea anyway,
since the other PMU registers have been enumerated since v4.10.
