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

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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
