From: Maarten Lankhorst <maarten.lankhorst at canonical.com> Commit de7b7d59d54852c introduced tiled GART, but a linear copy is still performed. This may result in errors on eviction, fix it by checking tiling from memtype.

Hello everyone, GK20A is the Kepler-based GPU used in the upcoming Tegra K1 chips. The following patches perform architectural changes to Nouveau that are necessary to support non-PCI GPUs and add initial support for GK20A. Although the support is still very basic and more user-space changes will be needed to make the full graphics stack run on top of it, we were able to successfully open

This series depends on the previously posted reservation api patches. 2 of them are not yet in for-next-fences branch of git://git.linaro.org/people/sumit.semwal/linux-3.x.git The missing patches are still in my vmwgfx_wip branch at git://people.freedesktop.org/~mlankhorst/linux All ttm drivers are converted to the fence api, fence_lock is removed and rcu is used in its place. qxl is the first

fence_is_signaled callback should support being run in atomic context, but not in irq context.

This series applies on top of the driver-core-next branch of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core.git Before converting ttm to the new fence interface I had to fix some drivers to require a reservation before poking with fence_obj. After flipping the switch RCU becomes available instead, and the extra reservations can be dropped again. :-) I've done at least basic
