Subject: [PATCH v2 4/5] KVM: arm64: vgic-v3: Don't advertise ICC_CTLR_EL1.SEIS
Date: Sun, 10 Oct 2021 16:09:09 +0100 [thread overview]
Message-ID: <20211010150910.2911495-5-maz@kernel.org> (raw)
In-Reply-To: <20211010150910.2911495-1-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.
