Subject: [RFC PATCH 24/28] arm64: rme: allow userspace to inject aborts
Date: Fri, 27 Jan 2023 11:29:28 +0000	[thread overview]
Message-ID: <20230127112932.38045-25-steven.price@arm.com> (raw)
In-Reply-To: <20230127112932.38045-1-steven.price@arm.com>

From: Joey Gouly <joey.gouly@arm.com>

Extend KVM_SET_VCPU_EVENTS to support realms, where KVM cannot set the
system registers, and the RMM must perform it on next REC entry.
