Subject: [PATCH v2 3/6] KVM: x86: Select CONFIG_HAVE_KVM_DIRTY_RING_ACQ_REL
Date: Mon, 26 Sep 2022 15:51:17 +0100 [thread overview]
Message-ID: <20220926145120.27974-4-maz@kernel.org> (raw)
In-Reply-To: <20220926145120.27974-1-maz@kernel.org>
Since x86 is TSO (give or take), allow it to advertise the new
ACQ_REL version of the dirty ring capability. No other change is
required for it.
