[Intel-gfx] [PATCH xserver] Make PixmapDirtyUpdateRec::src a DrawablePtr

Michel Dänzer michel at daenzer.net
Tue Apr 18 10:07:53 UTC 2017


From: Michel Dänzer <michel.daenzer at amd.com>

This allows making the master screen's pixmap_dirty_list entries
explicitly reflect that we're now tracking the root window instead of
the screen pixmap, in order to allow Present page flipping on master
outputs while there are active slave outputs.

Define HAS_DIRTYTRACKING_DRAWABLE_SRC for drivers to check, but leave
HAS_DIRTYTRACKING_ROTATION defined as well to make things slightly
easier for drivers.

Signed-off-by: Michel Dänzer <michel.daenzer at amd.com>
---

The Start/StopFlippingPixmapTracking related changes are only compile
tested. The rest is smoke tested with the modesetting, amdgpu and radeon
drivers.
