Subject: [PATCH v1 1/3] iommu/vt-d: Fix prq reporting issues
Date: Wed, 28 Oct 2020 09:36:56 +0800 [thread overview]
Message-ID: <1603849018-6578-2-git-send-email-yi.y.sun@linux.intel.com> (raw)
In-Reply-To: <1603849018-6578-1-git-send-email-yi.y.sun@linux.intel.com>
From: Liu Yi L <yi.l.liu@intel.com>
Should get correct sid and set it into sdev. Because we execute
'sdev->sid != req->rid' in the loop of prq_event_thread().
