For this v2 I have fixed the patches that are non-controversial (all Lucas' :)) and am resubmitting them in the hope that they will get merged. This will just leave the issue of Nouveau system-memory buffers mapping to be solved. This issue is quite complex, so let me summarize the situation and the data I have at hand. ARM caching is like a quantum world where Murphy's law constantly

This small series introduces TTM helper functions as well as Nouveau hooks that are needed to ensure buffer coherency on ARM. Most of this series is a forward-port of some patches Lucas Stach sent last year and that are also needed for Nouveau GK20A support: http://lists.freedesktop.org/archives/nouveau/2013-August/014026.html Another patch takes care of flushing the CPU write-buffer when

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

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
