Subject: [PATCH v8 58/69] KVM: arm64: nv: Add include containing the VNCR_EL2 offsets
Date: Tue, 31 Jan 2023 09:24:53 +0000 [thread overview]
Message-ID: <20230131092504.2880505-59-maz@kernel.org> (raw)
In-Reply-To: <20230131092504.2880505-1-maz@kernel.org>
VNCR_EL2 points to a page containing a number of system registers
accessed by a guest hypervisor when ARMv8.4-NV is enabled.
Let's document the offsets in that page, as we are going to use
this layout.
