From: Thierry Reding thierry.reding@avionic-design.de Subject: [RFC 0/4] Add NVIDIA Tegra DRM support Date: Wed, 11 Apr 2012 14:10:26 +0200 Message-ID: 1334146230-1795-1-git-send-email-thierry.reding@avionic-design.de
This series adds a basic DRM driver for NVIDIA Tegra 2 processors. It currently only supports the RGB output and I've successfully tested it against the fbcon kernel module and the xf86-video-modesetting driver. The code uses the Tegra's IOMMU/GART to remap non-contiguous memory. This means that currently video memory is limited to 32 MB, the size of the GART aperture.
Note that this is very early work-in-progress and there is a lot of room for improvement and cleanup. You'll also note that there is still a whole lot of debugging output, most of which is disabled by default.
However I explicitly wanted to post this early to get feedback and to discuss options on how to get this included in the mainline kernel. I have been in contact with some people at NVIDIA and they seem to be willing to work together on a solution that satisfies both their requirements and those of the community.

Thierry Reding (3): iommu: tegra/gart: Add device tree support drm: fixed: Add dfixed_frac() macro drm: Add NVIDIA Tegra support
Vandana Salve (1): iommu: tegra/gart: use correct gart_device
I guess that the following 2 patches can be merged now, independet of the rest of drm patches.
[RFC 1/4] iommu: tegra/gart: use correct gart_device [RFC 2/4] iommu: tegra/gart: Add device tree support
