Subject: [PATCH v3 21/21] KVM: arm64: selftests: Teach get-reg-list about FPMR
Date: Tue, 05 Dec 2023 16:48:19 +0000 [thread overview]
Message-ID: <20231205-arm64-2023-dpisa-v3-21-dbcbcd867a7f@kernel.org> (raw)
In-Reply-To: <20231205-arm64-2023-dpisa-v3-0-dbcbcd867a7f@kernel.org>
FEAT_FPMR defines a new register FMPR which is available at all ELs and is
discovered via ID_AA64PFR2_EL1.FPMR, add this to the set of registers that
get-reg-list knows to check for with the required identification register
depdendency.
