This is v2 of some present fixes for issues discovered when adding DRI3+present support to the PVR video driver.
Patch 1 has been reworked to now always restore the screen pixmap at the point a pending flip is marked as aborted. Previously it only did this in one place and only for the root window. Patch 2 is new and deals with the same problem, but in in different way, as the old patch 2. Essentially both patches attempt to deal with resource leaks related to flipping. The old patch did this by preventing any pending flip, associated with the window being destroyed, from being aborted and destroyed during window destruction. However, this relied on the DDX waiting for all kernel events to arrive and be processed so that the necessary resource clean up was triggered. The new patch just does the clean up at the point the window is destroyed. Patch 3 is identical to the old patch 4 (as patch 3 has now been dropped). Some issues still remain but these are fixed by the following patches that are currently on the list but not in master: - [PATCH] present: Queue flips for later execution - [PATCH 3/6] present: Reorder Window teardown to avoid use-after-free Frank Binns (3): present: restore screen pixmap when aborting a flip present: clean up all current flip resources on window destruction present: sync flips unless requested not to present/present.c | 44 ++++++++++++++++++++++++++------------------ present/present_priv.h | 2 +- present/present_screen.c | 7 ++++--- 3 files changed, 31 insertions(+), 22 deletions(-) -- 1.8.5.4.gfdaaaa2 _______________________________________________ [email protected]: X.Org development Archives: http://lists.x.org/archives/xorg-devel Info: http://lists.x.org/mailman/listinfo/xorg-devel
