The DRM core will translate calls to legacy cursor ioctls into universal cursor calls automatically, so there's no need to maintain the legacy cursor support. This greatly simplifies the transition since we don't have to handle reference counting differently depending on which cursor interface was called. The aim here is to transition to the universal plane interface with minimal code change. There's a lot of cleanup that can be done (e.g., using state stored in crtc->cursor->fb rather than intel_crtc) that is left to future patches. v4: - Drop drm_gem_object_unreference() that is no longer needed now that we receive the GEM obj directly rather than looking up the ID. v3: - Pass cursor obj to intel_crtc_cursor_set_obj() if cursor fb changes, even if 'visible' is false. intel_crtc_cursor_set_obj() will notice that the cursor isn't visible and disable it properly, but we still need to get intel_crtc->cursor_addr set properly so that we behave properly if the cursor becomes visible again in the future without changing the cursor buffer (noted by Chris Wilson and verified via i-g-t kms_cursor_crc). - s/drm_plane_init/drm_universal_plane_init/. Due to type compatibility between enum and bool, everything actually works correctly with the wrong init call, except for the type of plane that gets exposed to userspace (it shows up as type 'primary' rather than type 'cursor'). v2: - Remove duplicate dimension checks on cursor - Drop explicit cursor disable from crtc destroy (fb & plane destruction will take care of that now) - Use DRM plane helper to check update parameters Cc: intel-gfx@lists.freedesktop.org Signed-off-by: Matt Roper <matthew.d.roper@intel.com> Reviewed-by: Pallavi G<pallavi.g@intel.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> |
