[Intel-gfx] [PATCH 6/7] drm/i915: Switch plane handling to atomic helpers (v5)
Matt Roper
matthew.d.roper at intel.com
Tue Dec 9 11:53:42 PST 2014
Now that we have hooks to enable the atomic plane helpers, we can use
the plane helpers for our .update_plane() and .disable_plane()
entrypoints.
Note that we still need to make a few small behavioral changes to the
driver entrypoints here as we make the transition, due to differences
between how the atomic helpers set things up for us vs how our internal
functions were setting things up.
v2: Fix commit message typo (Bob)
v3: Rebased on top of Gustavo Padovan's patches to kill off
intel_crtc_cursor_set_obj() and intel_pipe_set_base().
v4: Rebase again on latest display refactor series. Now that previous
patches have smoothed the rough edges of the existing display code,
the transition here is much less painful.
v5: Plane helpers will re-prepare the same fb for a plane. Drop the
WARN on this condition.
Testcase: igt/kms_plane
Testcase: igt/kms_universal_plane
Testcase: igt/kms_cursor_crc
