Subject: [Intel-gfx] [PATCH 0/2] Fixes for incoming smarter IOMMU
Date: Thu, 10 Sep 2020 12:58:58 +0100 [thread overview]
Message-ID: <20200910115900.407686-1-tvrtko.ursulin@linux.intel.com> (raw)
From: Tvrtko Ursulin <tvrtko.ursulin@intel.com>
There are incoming improvements to Intel IOMMU code to allow sg table
coalescing on map operations. We do not handle that well (we assume 1:1 between
backing store and DMA mapped entries) so this series is an attempt to improve
this area and get ready for those changes.
