[PATCH 0/4] drm/ttm: nouveau: memory coherency fixes for ARM

From: Alexandre Courbot
Date: Mon May 19 2014 - 03:11:30 EST


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:

Another patch takes care of flushing the CPU write-buffer when writing BOs
through a non-BAR path.

Alexandre Courbot (1):
drm/nouveau: introduce CPU cache flushing macro

Lucas Stach (3):
drm/ttm: recognize ARM arch in ioprot handler
drm/ttm: introduce dma cache sync helpers
drm/nouveau: hook up cache sync functions
