Subject: [PATCH 0/5] drm/tegra: Fix IOVA space on Tegra186 and later
Date: Wed, 23 Jan 2019 10:39:46 +0100 [thread overview]
Message-ID: <20190123093951.24908-1-thierry.reding@gmail.com> (raw)
From: Thierry Reding <treding@nvidia.com>
Tegra186 and later are different than earlier generations in that they
use an ARM SMMU rather than the Tegra SMMU. The ARM SMMU driver behaves
slightly differently in that the geometry for IOMMU domains is set only
after a device was attached to it. This is to make sure that the SMMU
instance that the domain belongs to is known, because each instance can
have a different input address space (i.e. geometry).
Work around this by moving all IOVA allocations to a point where the
geometry of the domain is properly initialized.
This supersedes the following patch:

Thierry Reding (5):
drm/tegra: Store parent pointer in Tegra DRM clients
drm/tegra: vic: Load firmware on demand
drm/tegra: Setup shared IOMMU domain after initialization
drm/tegra: Restrict IOVA space to DMA mask
gpu: host1x: Supports 40-bit addressing on Tegra186
