2013-02-10sna: Backport to squeeze - Xorg-1.6, pixman-0.16, libdrm-2.4.21Chris Wilson
The principle change is to switch to the old Privates API and undo the Region renames. The downside is that this ignores the critical bugfixes made to the xserver since xorg-1.6 - but I assume that whoever wants to run the latest hardware on the old xservers is also backporting those stability fixes...

2013-01-14sna: Apply PutImage optimisations to move-to-cpuChris Wilson
We can replace the custom heuristics for PutImage by applying them to the common path, where hopefully they are equally valid. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2012-07-14sna: Aim for consistency and use stdbool except for core X APIsChris Wilson

2012-07-09sna: Simplify the DBG incarnationChris Wilson
It was only ever used in conjunction with HAS_DEBUG_FULL. For debug purposes it is as easy to redefine DBG locally. By simplifying the DBG macro we can create it consistently and so reduce the number of compiler warnings. Long term, this has to be dynamic. Sigh.

2012-01-27sna: Use a proxy rather than a temporary bo for too-tall but thin targetsChris Wilson
If the render target is thin enough to fit within the 3D pipeline, but is too tall, we can fudge the address of the origin and coordinates to fit within the constaints of the pipeline. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>

2012-01-23sna: Assert that the subtract operation does reduce an all-damagedChris Wilson
Somewhere somewhen it appears that I am discarding the all-damaged flag on the pointer. The only possibility I can see is for a no-op subtraction, so put an assert there just in case the impossible is happening. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2012-01-12sna: Store damage-all in the low bit of the damage pointerChris Wilson
Avoid the function call overhead by inspecting the low bit to see if it is all-damaged already. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>

2011-12-24sna: Remove the independent tracking of elts from boxesChris Wilson
Following the switch to a global mode for damage, the elts array became redundant and all that is required is the list of boxes. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2011-12-12sna: Defer allocation of memory for larger pixmap until first useChris Wilson
In the happy scenario where the pixmap only resides upon the GPU we can forgo the CPU allocation entirely. The goal is to reduce the number of needless mmaps performed by the system memory allocator and reduce overall memory consumption. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>

2011-10-21sna/damage: Only track the mode globallyChris Wilson
As damage accumulation is handled modally, we do not need to track the mode per elt and so attempt to simplify the code. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2011-10-20sna: Actually apply the composite offset for the self-copyChris Wilson
I translated the region to copy by the composite pixmap offset, only failed to use the translated region for the actual copy command (using instead the original boxes). Fix that mistake by avoiding the temporary region entirely and applying the translation inplace. We also have to be careful in the case of copying between two composited windows that have different offsets into the same screen pixmap. This fixes the regression introduced with a3466c8b69af (sna/accel: Implement a simpler path for CopyArea between the same pixmaps). Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>

2011-06-04sna: Introduce a new acceleration model.Chris Wilson
The premise is that switching between rings (i.e. the BLT and RENDER rings) on SandyBridge imposes a large latency overhead whilst rendering. The cause is that in order to switch rings, we need to split the batch earlier than is desired and to add serialisation between the rings. Both of which incur large overhead. By switching to using a pure 3D blit engine (ok, not so pure as the BLT engine still has uses for the core drawing model which can not be easily represented without a combinatorial explosion of shaders) we can take advantage of additional efficiencies, such as relative relocations, that have been incorporated into recent hardware advances. However, even older hardware performs better from avoiding the implicit context switches and from the batching efficiency of the 3D pipeline... But this is X, and PolyGlyphBlt still exists and remains in use. So for the operations that are not worth accelerating in hardware, we introduce a shadow buffer mechanism through out and reintroduce pixmap migration. Doing this efficiently is the cornerstone of ensuring that we do exploit the increased potential of recent hardware for running old applications and environments (i.e. so that the latest and greatest chip is actually faster than gen2!) For the curious, sna is SandyBridge's New Acceleration. If you are running older chipsets and welcome the performance increase offered by this patch, then you may choose to call it Snazzy instead.

By enabling such operations is the only way to one day be faster than purely using the CPU, in the meantime we suffer regression due to the increased migration and aperture thrashing. The other couple of regressions will be eliminated with improved span and shader support, now that the framework for such is in place.] The performance increase for Cairo completely overlooks the other critical aspects of the architecture: World of Padman: gen3 (800x600): 57.5 -> 96.2 gen4 (800x600): 47.8 -> 74.6 gen6 (1366x768): 100.4 -> 140.3 [F15] 144.3 -> 146.4 [drm-intel-next] x11perf (gen6); aa10text: 3.47 -> 14.3 Mglyphs/s [unthrottled!] copywinwin10: 1.66 -> 1.99 Mops/s copywinpix10: 2.28 -> 2.98 Mops/s And we do not have a good measure for how much improvement the reworking of the fallback paths give, except that xterm is now over 4x faster...
