from Emil Velikov
You're a star J=C3=A1n
Just had a word with our main dev and he suggested that
viewport transformation is optional, whereas viewport clip rectangle must be
set before and after 3d_blit().
With that said, here is what can be done to double-check/fix this - note a
quick piglit [1] test before and after each one, plus testing of other game=
s/gl
apps is essential.
* nuke the viewport clip rectangle (despite all odds)
* change the viewport clip rectangle - traceback and use the original values
(the ones saved at the begingin on 3d_blit() and restored at the end)
* nuke the viewport transformation
* add the conditional NV50_TIC_5_LAST_LEVEL__MASK on tic[5] in
nvc0_create_texture_view (compare vs nv50_create_texture_view)
I'm hoping that one of the last two will do the job, although chances are t=
hat
it may be one of the first two. Either way a piglit and further testing will
prove which solution is the most appropriate.
Feel free to give it a shot yourself, as it will take a some time until I g=
et
to it(apart from the lack of HW).
Note: depending on your luck(and other unknown to me factors) piglit may lo=
ckup
X and your system. Normally a s2r cycle is sufficient to get it back into
shape, otherwise a reboot is needed.
Cheers,
Emil
