Subject: [PATCH v2 2/8] KVM: arm64: nv: Add CGT description for FEAT_PoPS instructions
Date: Fri,  6 Nov 2026 10:31:48 -0800	[thread overview]
Message-ID: <20261106183154.3590825-3-oupton@kernel.org> (raw)
In-Reply-To: <20261106183154.3590825-1-oupton@kernel.org>

The DC CIVAPS and DC CIGDVAPS instructions are both affected by
HCR_EL2.TPCP. Add the missing CGT descriptors.

Fixes: a7484c80e5ca ("KVM: arm64: Allow userspace to request KVM_ARM_VCPU_EL2*")
Reviewed-by: Leonardo Bras <leo.bras@arm.com>
