Subject: [Qemu-devel] [PATCH 2/5] intel_iommu: reset intr_enabled when system reset
Date: Tue, 8 Jan 2019 19:47:17 +0800 [thread overview]
Message-ID: <20190108114720.21760-3-peterx@redhat.com> (raw)
In-Reply-To: <20190108114720.21760-1-peterx@redhat.com>
This is found when I was debugging another problem. Until now no bug
is reported with this but we'd better reset the IR status correctly
after a system reset.
