Subject: [PATCH 01/11] KVM: arm64: CCA: Reserve the RMM mode
Date: Mon, 2 Nov 2026 14:12:52 +0000 [thread overview]
Message-ID: <20261102141304.126883-2-steven.price@arm.com> (raw)
In-Reply-To: <20261102141304.126883-1-steven.price@arm.com>
Reserve KVM_MODE_RMM for CCA realm support. The kernel parameter that
selects this mode will be added when the Linux CCA implementation is
ready.
