Subject: [PATCH v3 16/27] KVM: arm64: nv: Expose FEAT_EVT to nested guests
Date: Tue,  8 Aug 2023 12:47:00 +0100	[thread overview]
Message-ID: <20230808114711.2013842-17-maz@kernel.org> (raw)
In-Reply-To: <20230808114711.2013842-1-maz@kernel.org>

Now that we properly implement FEAT_EVT (as we correctly forward
traps), expose it to guests.
