2014-06-11sna: Silence compiler warnings for discarding const Region pointsChris Wilson
Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2014-06-05sna: Curry parameters to sna_damage_all()Chris Wilson
It is far easily to pass the PixmapPtr into the function and have it pluck out the width and height than do so in all callers. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
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>
2014-01-17sna: 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>
2013-10-08sna: Rework the num_threads refinement to avoid the divisionChris Wilson
We can replace the division by a multiplication. 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>
2013-10-07sna/trapezoids: Only use a single thread to emit rectilinear spansChris Wilson
If the trapezoids are rectilinear, they should hit a fast path through the span compositors and so threading them seems pointless. Expect possibily for inplace pixman operations. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2013-10-07sna/trapezoids: Restore overflow checkChris Wilson
The range can indeed overflow, so promote the assertion back into a check. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2013-10-07sna/trapezoids: Fix overstepping vertical edgesChris Wilson
Regression from commit c98b770a87a5ec5ed9dc0aa375ad173b0e98322e Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Fri Oct 4 18:37:01 2013 +0100 sna/trapezoids: Add a precise scan converter 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>
2013-10-05sna/trapezoids: Add a precise scan converterChris Wilson
Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2013-10-04sna: Start splitting the trapezoids megafile into parseable blocksChris Wilson
Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
