Subject: [PATCH v2] PCI/MSI: Avoid torn updates to MSI pairs
Date: Sat, 25 Jan 2020 10:32:46 -0800	[thread overview]
Message-ID: <1579977166-63618-1-git-send-email-jacob.jun.pan@linux.intel.com> (raw)
In-Reply-To: <20200117162444.v2.1.I9c7e72144ef639cc135ea33ef332852a6b33730f@changeid>

It seems we could avoid force_retrigger once IR is turned on. I have tried
this patch with IR turned on, still seeing force_retrigger=1 for MSIs w/o
masking.
