Hi,
these patches apply on top of my ARB_shader_image_load_store series.
Together,
they fix a few remaining fails with piglit's
arb_shader_image_load_store-host-mem-barrier.
You can see them in context at
https://cgit.freedesktop.org/~nh/mesa/log/?h=ssbo
The basic assumption for how barrier bits are translated is that each
Gallium
object / binding point has its own PIPE_BARRIER_* bit, but the driver
will
automatically do the necessary invalidations/flushes for transfers and
blit-type operations, as well as when the framebuffer state is changed.
This is still very tricky stuff to get right, but at least I think it's
shaping up nicely for radeonsi, as evidenced by the fact that the
host-mem-barrier test passes (and the control subtests also show that
what we're doing here isn't just a no-op). Please review!
Thanks,
Nicolai
