Subject: [PATCH 0/3] drm/tegra: A couple of fixes for v5.6-rc1
Date: Tue,  4 Feb 2020 14:59:23 +0100	[thread overview]
Message-ID: <20200204135926.1156340-1-thierry.reding@gmail.com> (raw)

From: Thierry Reding <treding-DDmLM1+adcrQT0dZR+AlfA@public.gmane.org>

Hi,

this contains a couple of fixes for a DMA API performance regression
that was introduced in v5.5 for older Tegra devices. Patches 1 and 2
will likely have to be backported to v5.5.

Thierry Reding (3):
  drm/tegra: Relax IOMMU usage criteria on old Tegra
  drm/tegra: Reuse IOVA mapping where possible
  gpu: host1x: Set DMA direction only for DMA-mapped buffer objects
