[Nouveau] nvfx

Fri Jun 11 06:37:20 PDT 2010

Hi Marek

Thanks a lot for your rebasing work.
Here is my report :

- all my games that broke with temporaries patch (they were either
completely black or lot of black screen flash every frame) behave
badly, but in different ways :
* etracer is very slow and often crash in ttm code [1] (I think this
is an old bug that just resurrected, no idea why)
* foobillard is very slow and still flash a bit
* strangely, neverball seems to work, I get similar results than with
old nvfx-next-6b branch with temporaries reverted. no black flash
while playing.
* glest segfault [2]

I also compared with piglit the old nvfx branch with the new merged one :
114/174 vs 113/174
That looks quite good with 3 new pass, but 4 new fail :
* fbo-copypix
Returncode was -6
* glean pbo
     ../../../../src/gallium/auxiliary/util/u_inlines.h:77:pipe_reference:
Assertion `pipe_is_referenced(reference)\\\' failed.
* texCombine4:  FAIL rgba8, db, z24, s8, win+pmap, id 33
* fp-long-alu

There is just fp-long-alu that is for sure a regression caused by new
master code (some gallium changes). I don't know about the 3 others.

It might be worth to re-test everything on your new branch with this
patch reverted :
nvfx: rewrite render temporaries code, also affecting 2D and resource code
