[Mesa-dev] [PATCH 00/12] i965: Add support for 16x MSAA on SKL+

[Neil Roberts]

I ran the series through Piglit but there are some issues.

The texelFetch test appears to be broken for sample counts > 10 and
needs this patch to work:

The accuracy tests are failing but I think the problem is just that it
is too strict. I've written a page about this with a diagram here:

The following tests are failing but on my SKL device the corresponding
tests with 8 samples are also failing. As far as I understand these
aren't known regressions for other people so it may be something to do
with my device being pre-production. It would be great if someone
could test on a production device.

 multisample-formats 16 gl_arb_texture_float 
 multisample-formats 16 gl_arb_texture_rg
 multisample-formats 16 gl_arb_texture_rg-float
 multisample-formats 16 gl_arb_texture_rg-int 
 multisample-formats 16 gl_ext_packed_float
 multisample-formats 16 gl_ext_texture_integer
 multisample-formats 16 gl_ext_texture_snorm
 multisample-formats 16 gl_ext_texture_srgb 
 alpha-to-one-dual-src-blend 16 
 formats 16
 blit-scaled samples=16

These two tests are only failing with 16 samples but so far I haven't
been able to figure out why. I'm hoping that these will magically pass
on a production device.

 unaligned-blit 16 color msaa 

Jenkins is reporting some unstable tests on g45 and g965 but they
don't seem related so I'm a bit confused.
