[Intel-xe] [PATCH 00/10] Split out most of "FIXME: drm/i915/display: Remaining changes to make xe compile"

[Maarten Lankhorst]

A lot of  the changes are reverts that are no longer useful. In some cases the
compat headers provide functionality, in other cases it needs to be added.

With all reverts, the fixme patch should be mostly isolated to intel_fb.c and intel_fbdev.c

Untested.

Maarten Lankhorst (10):
  revert fixme in intel_atomic_plane.c
  drm/atomic: Add drm_atomic_helper_set_fence_deadline() function
  drm/i915: Implement fence->set_deadline.
  FIXME drm/i915/display: Use fence->set_deadline to boost requests
  fixup xe i915_drv.h compat header
  revert intel_frontbuffer changes.
  Update compat headers.
  more reverts
  drm/i915/display: Use i915_gem_object_get_dma_address to get dma
    address
  revert more (fbc)

Re: [Intel-xe] [04/10] FIXME drm/i915/display: Use fence->set_deadline to boost requests

[Hogander, Jouni]

Hello Maarten,

We have ongoing discussion in gfx mailing list
(https://patchwork.freedesktop.org/series/125160/). I understood we
have now there clear path forward. I will prepare one more addresing
recent comments from Ville. That patch set which will take care of
this. After getting it merged into drm-intel-next I will backport it to
drm-xe-next and it will solve this.

BR,

Re: [Intel-xe] [06/10] revert intel_frontbuffer changes.

Hello Maarten.

Instead of introducing completely new patch I think you should change
this as a fixup patch for "FIXME: drm/i915/display: Remaining changes
to make xe compile"

BR,

[Intel-xe] [PATCH 07/10] Update compat headers.

[Maarten Lankhorst]

Some naughty headers used I915_GEM_OBJECT_H instead of their own name,
fix it.

Update headers to move some stuff out from the messy patch.
