[Intel-gfx] [PATCH 0/3] pwrite patches to handle GTT userspace pointers

[Daniel Vetter]

Hi all,

Chris and me have some decent fun in tuning pwrite/pread and related areas,
but it looks like it'll take some more time until thing settle out.

But I don't want to delay the fixes for handling GTT mmaps as userspace
src/dst for pwrite/pread any longer. Hence I've split them out.

Comments, reviews, flames and colour suggestions highly welcome.

Cheers, Daniel

  drm/i915: fall through pwrite_gtt_slow to the shmem slow path
  drm/i915: rewrite shmem_pwrite_slow to use copy_from_user
  drm/i915: rewrite shmem_pread_slow to use copy_to_user
