2015-05-17sna: Wrap CPU access for composite operations with sigtrapChris Wilson
Anytime we access a mmap() we need to be prepared for the kernel to send us a SIGBUS, but we were missing a few sigtraps around calls to pixman_fill and pixman_blt. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2014-09-10sna: Prune damage that covers the entire target PixmapChris Wilson
Reduce it early and mark it complete. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2014-09-02sna/trapezoids: Use the corrected trapezoid origin for aligned boxesChris Wilson
The rule for the origin of the CompositeTrapezoids routine is the upper-left corner of the first trapezoid. Care must be taken in case the trapezoid edge is upside down to consider the upper vertex.

2014-07-04sna: Disable use of threaded compositor when using threaded rendererChris Wilson

2014-06-20sna: Mark up const boxes to keep the compiler happyChris Wilson
Pass around const to suppress a few compiler warnings. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2014-06-11sna: Silence compiler warnings for discarding const Region pointsChris Wilson

2014-05-06sna: Refine hints to allow inplace writes whilst compositing aligned trapsChris Wilson

2014-03-10sna: Pass render hints for migration based on source locationChris Wilson

2014-02-22sna: Allow SIGBUS/SEGV to kill the threadChris Wilson
To handle sigtrapping of the threads, we allow the threads to handle their async signals and upon hitting the trap, we kill the thread. All the rest of the threads are reaped by the main xserver thread afterwards. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2014-02-22sna: Handle asynchronous signals from threadsChris Wilson
By killing the threads and leaking their allocations - marginally preferrable to losing the entire Xserver. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2014-02-21sna: Wrap inplace trapezoid operators with SIGBUS protectionChris Wilson
For the moment, this still leaves open the vexing question of how to protect the multi-threaded variants, but it should provide more shelter for extreme OOM. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2014-01-23sna: Avoid erroneous discarding operations for partial compositesChris Wilson
Composite operations were presumed to cover their entire width x height area. However, a few paths submit boxes that do not cover the clip region and so the optimisation made during prepare to discard completely overwritten data is incorrect (and leads to corruption - stale data is seen which the client expected to have been overdrawn). So along these more unusual paths, we must add a flag to prevent the overzealous discard. Notably, xfce4 triggers this as it uses a lot of unantialiased trapezoids in its theme drawing.

2014-01-17sna: Cull the DBG spew to stderrChris Wilson
Reduce the logging verbosity of DBG so that it only appears in the logfile by default - makes debugging much more pleasant. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2013-11-14sna/gen6+: Only substitute SRC for CLEAR if using the correct sourceChris Wilson
If the source has not been verified to be clear, then using the SRC operator will paint the wrong color. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2013-10-08sna/trapezoids: Recompute num_threads to match rangeChris Wilson
We need to be careful not to execute threads past the end of the alloted buffer by making sure the clip extents correctly align. Reported-by: Joseph Yasi <joe.yasi@gmail.com> Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=70204 Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
