Subject: [PATCH 3/6] KVM: x86: Select CONFIG_HAVE_KVM_DIRTY_RING_ORDERED
Date: Thu, 22 Sep 2022 18:01:30 +0100 [thread overview]
Message-ID: <20220922170133.2617189-4-maz@kernel.org> (raw)
In-Reply-To: <20220922170133.2617189-1-maz@kernel.org>
Since x86 is TSO (give or take), allow it to advertise the new
ORDERED version of the dirty ring capability. No other change is
required for it.
