Subject: [PATCH v3 09/27] KVM: arm64: nv: Advertise support for FEAT_RAS
Date: Tue,  8 Jul 2025 10:25:14 -0700	[thread overview]
Message-ID: <20250708172532.1699409-10-oliver.upton@linux.dev> (raw)
In-Reply-To: <20250708172532.1699409-1-oliver.upton@linux.dev>

Now that the missing bits for vSError injection/deferral have been added
we can merrily claim support for FEAT_RAS.
