Subject: [PATCH 3/5] KVM: arm64: vgic-v3: Don't advertise ICC_CTLR_EL1.SEIS
Date: Fri, 24 Sep 2021 09:25:40 +0100	[thread overview]
Message-ID: <20210924082542.2766170-4-maz@kernel.org> (raw)
In-Reply-To: <20210924082542.2766170-1-maz@kernel.org>

Since we are trapping all sysreg accesses when ICH_VTR_EL2.SEIS
is set, and that we never deliver an SError when emulating
any of the GICv3 sysregs, don't advertise ICC_CTLR_EL1.SEIS.
