A week in, grab the brown paper bags, for it is time to reveal a couple
of critical bugs that spoilt the 2.20.0 release.
Firstly we have the restoration of DRI for i810. I am sure that the
solitary user will be overjoyed in a couple of years when a new xserver
is forced upon it. That enjoyment will be short-lived as no actual
acceleration remains, not even shadow, for the chipset.
Perhaps a little more wildly felt, I hope!, will be that the SNA
fallbacks were broken on 64-bit machines if they required clipping. One
little misplaced cast of a pointer, and the screen is filled with
corruption.
Among the other tweaks this week:
* A bug affecting gen4 handling of trapezoids was fixed, and CPU
overhead reduced.
https://bugs.freedesktop.org/show_bug.cgi?id=52158
* A fix for a bug causing corruption of a DRI2 unredirected client
window that was resized whilst under a compositor.
* Support for snoopable buffers on non-LLC architectures, coming to
a future kernel. The aim to accelerate transfers between the CPU
and the GPU, in particular to dramatically improve readback
performance, and to further minimise clflushes.
* Improvement to the composite performance on GT2 SandyBridge and
IvyBridge devices, in particular the render copy is significantly
improved.
* Improved handling for when acceleration is disabled, including
permitting DRI2 to remain supported even if the X server believes
the GPU wedged.
* Shadow support was dropped from UXA as it was neither complete nor
correct, use SNA instead.
