[Mesa-dev] [PATCH 5/6] radeonsi: add GS multiple streams support

Dave Airlie airlied at gmail.com
Sun Jul 26 18:50:02 PDT 2015


From: Dave Airlie <airlied at redhat.com>

This is the final piece for ARB_gpu_shader5,

The code is based on the r600 code from Glenn Kennard,
and myself.

While developing this, I'm not 100% sure of all the calculations
made in the GS registers, this is why the max_stream is worked
out there and used to limit the changes in registers. Otherwise
my initial attempts either regressed GS texelFetch tests
or primitive-id-restart. The current code has no regressions
in piglit.

This commit doesn't enable ARB_gpu_shader5, since that just
bumps the glsl level to 4.00, so I'll just do a separate patch
for 4.10.
