i965/fs: Reset the register file to VGRF in lower_integer_multiplication

18fde36ced4279f2577097a1a7d31b55f2f5f141 changed the way temporary
registers were allocated in lower_integer_multiplication so that we
allocate regs_written(inst) space and keep the stride of the original
destination register.  This was to ensure that any MUL which originally
followed the CHV/BXT integer multiply regioning restrictions would
continue to follow those restrictions even after lowering.  This works
fine except that I forgot to reset the register file to VGRF so, even
though they were assigned a number from alloc.allocate(), they had the
wrong register file.  This caused some GLES 3.0 CTS tests to start
failing on Sandy Bridge due to attempted reads from the MRF:

    ES3-CTS.functional.shaders.precision.int.highp_mul_fragment.snbm64
    ES3-CTS.functional.shaders.precision.int.mediump_mul_fragment.snbm64

    ES3-CTS.functional.shaders.precision.uint.mediump_mul_fragment.snbm64
    ES3-CTS.functional.shaders.precision.uint.lowp_mul_fragment.snbm64

This commit remedies this problem by, instead of copying inst->dst and
overwriting nr, just make a new register and set the region to match
inst->dst.

i965: Stop disabling aux during texture preparation

Previously, we were handling self-dependencies by marking the render
buffer and then passing disable_aux=true to prepare_texture so that it
would do a resolve.  This works but ends us up doing to much resolving

generation, this would cause us to resolve all levels of the texture if
even one of them is overlapping.

Instead, this commit makes us wait until we process the framebuffer to
do these resolves and we only resolve the slices needed for rendering.
Doing this resolve puts them into the pass-through state so, even if we

real surface contents read.

i965/miptree: Add an aux_disabled parameter to render_aux_usage

Only one of the callers of intel_miptree_render_aux_usage actually took
brw->draw_aux_buffer_disabled into account.  This was causing us to
ignore draw_aux_buffer_disabled for the intel_miptree_prepare_render.
This isn't a problem because the draw_aux_buffer_disabled entry was set
during texture preparation and we already did the resolve at that time.
However, this also meant that the aux_usage we were passing to
brw_cache_flush_for_render and brw_render_cache_add_bo was wrong so our
automatic cache flushing around aux_usage changes wasn't happening.
This was causing GPU hangs in Oxenfree.

registers was always emitted eliminating the reladdr* handles in the

to be used for addressing on some hardware this changed, and
the tracking becomes necessary.

Because the registers have no direct indication on whether the reladdr* was
already loaded into an address register, the temporaries in reladdr* are
always tracked as reads. This may result in a slight over-estimation of the
lifetime in the cases when the load to the address register was emitted.

6 years agoanv: Separate compute and graphics descriptor sets
Jason Ekstrand [Fri, 15 Dec 2017 22:02:27 +0000 (14:02 -0800)]
anv: Separate compute and graphics descriptor sets

The Vulkan spec says:

    "pipelineBindPoint is a VkPipelineBindPoint indicating whether the
    descriptors will be used by graphics pipelines or compute pipelines.
    There is a separate set of bind points for each of graphics and
    compute, so binding one does not disturb the other."

Up until now, we've been ignoring the pipeline bind point and had just
one bind point for everything.  This commit separates things out into
separate bind points.
