Description

Speccyfighter 2019-05-30 00:57:11 MSK

Всем доброго

Суть:
На p9/branch и выше, на графике Интел Broadwell GT2 (gen8),с драйвером intel_drv, акселерация необратимо сваливается в UXA с серьёзным падением производительности. Вместо SNA, которая должна использоваться по-умолчанию.

p9/branch:

Вместо SNA используется UXA акселерация.


$ man intel | col -bfx | sed -n '131,144p'
       Option "AccelMethod" "string"
              Select acceleration method.  There  are  a  couple  of  backends
              available  for accelerating the DDX. "UXA" (Unified Acceleration
              Architecture) is the mature backend that was introduced to  sup‐
              port  the GEM driver model. It is in the process of being super‐
              seded by "SNA"  (Sandybridge's  New  Acceleration).  Until  that
              process  is complete, the ability to choose which backend to use
              remains for backwards compatibility.  In addition, there  are  a
              pair of sub-options to limit the acceleration for debugging use.
              Specify "off" or "none" to disable all acceleration, or "blt" to
              disable render acceleration and only use the BLT engine.

              Default: use SNA (render acceleration)

Зачем сделали disabled sna for i586?
https://packages.altlinux.org/ru/sisyphus/srpms/xorg-drv-intel

Которая работает в текущей Слаке 32 бит (post 14.2) по-умолчанию, но сейчас не работает в альтах 32 бит на p9.
