Subject: [PATCH v3 12/27] KVM: arm64: nv: Add FGT registers
Date: Tue,  8 Aug 2023 12:46:56 +0100	[thread overview]
Message-ID: <20230808114711.2013842-13-maz@kernel.org> (raw)
In-Reply-To: <20230808114711.2013842-1-maz@kernel.org>

Add the 5 registers covering FEAT_FGT. The AMU-related registers
are currently left out as we don't have a plan for them. Yet.
