I'm the maintainer of Mesa port for AROS (www.aros.org). I recently
backported Mesa 7.10 and noticed a considerable speed regression. After
some testing I narrowed the problem down to commit:
859106f196ade77f59f8787b071739901cd1a843, st/vega: Fix pipe blend state
for various blend modes.
My test case is lion demo:
softpipe, debug, without commit: ~7 FPS
softpipe, debug, with commit: ~0.13 FPS
nouveau, release, without commit: ~150 FPS
nouveau, release with commit: ~9FPS
PS. I'm not filling a bug report, since AROS port is not official and
the problem still might be down to something wrong with the port itself.
