2012-09-21sna: Use inplace X tiling for LLC uploadsChris Wilson
Based on a suggestion by Chad Versace (taken from a patch for mesa). This allows for a faster upload of pixel data through a ShmImage, or for complete replacement of a GPU bo. Using a modified version of x11perf to upload to a pixmap rather than scanout on an IVB i7-3720qm: Before: 40000000 trep @ 0.0007 msec (1410000.0/sec): ShmPutImage 10x10 square 4000000 trep @ 0.0110 msec ( 90700.0/sec): ShmPutImage 100x100 square 160000 trep @ 0.1689 msec ( 5920.0/sec): ShmPutImage 500x500 square After: 40000000 trep @ 0.0007 msec (1450000.0/sec): ShmPutImage 10x10 square 6000000 trep @ 0.0061 msec ( 164000.0/sec): ShmPutImage 100x100 square 400000 trep @ 0.1126 msec ( 8880.0/sec): ShmPutImage 500x500 square However, the real takeaway from this is that the overheads for ShmPutImage are substantial, only hitting around 70% expected efficiency, and overshadowed by PutImage, which for reference is 60000000 trep @ 0.0006 msec (1800000.0/sec): PutImage 10x10 square Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2012-09-20sna/gen3+: Trim the target extents to the CompositeClipChris Wilson
When computing the active region with of a composite operation with unknown extents we try to simply use the whole Drawable. However, this needs to be clipped otherwise it may trigger assertion failure with an offscreen pixmap.

2012-09-18sna: Remove special casing of drawing depth=1 glyphsChris Wilson
It turns out that they were not so special after all, and the "fast path" was missing the important handling such as validating the GC. As a result we ended up trying to render the glyphs through a planemask of 0 and similar garbage resulting in corruption. An example given by Kaus Dittrich was the use of rotated glyphs in gnuplot.

2012-09-14sna: Only discard CPU damage if we completely overwrite its extentsChris Wilson
If we are performing a clipped copy, then we must be careful not to completely discard the CPU damage as it may not be entirely replaced.

2012-09-14Skip adding unknown special modesChris Wilson
In light of the discussion on how to add stereo modes it was revealed that we would happily add modes with unknown and unhandled strange flags. Adam Jackson mentioned that he has plans to fix that with some upcoming work, but as a first step we can simply eradicate them whilst pondering how to support the stereoscopic vision of the future.

2012-09-10sna: Workaround issue with global glyph privates and shared ZaphodHeadsChris Wilson
Under ZaphodHeads we end up with multple screens accessing the common sna_glyph_key and so cause conflicting updates and erroneous references into the screen-local texture atlases. Two approaches can be tried here. Transition to a screen-specific private key introduced with xorg-1.13, or to move the glyph cache (and the rest of the gpu state tracker) down into the device private rather than screen private. This is neither of those, but a workaround to avoid reusing the incorrect entries from shared screens.
