[Intel-gfx] [PATCH 0/6] kernel modsetting support for intel overlay

[Daniel Vetter]

Hi all,

This series implements support for the intel overlay hw with kms.
Caveats/Remarks:
- the overlay image is flickering but stabilizes after a few secs of
  showing the same frame. I've researched intel ddx history/bugs and
  there was a similar issue in the original userspace modesetting driver,
  but I haven't found the solution. Hints/ideas highly appreciated.
- untested on anything else than a 855GM - this is the only hw I have.
  Especially panel fitting one-line-mode is completely untested. Testing
  this needs an LVDS with vertical resolution less than native but larger
  than 1024.
- patches 1, 4, 5 change drm-generic code.
- the ioctl interface is intel-only. Anyone (radeon devs?) working on another
  overlay implementation/interested in sharing code?

Yours, Daniel

PS: I'll post the ddx part shortly to intel-gfx.

  [drm]: make drm_mode_object_find typesafe
  [drm/i915] remove open-coded drm_mode_object_find
  [drm/i915]: modeset: always set intel_crtc->dpms_mode
  [drm/i915]: require_pipe_a helper functions
  [drm/i915]: add i915_lp_ring_sync helper
  [drm/i915] implement drmmode overlay support
