freedreno: deduplicate a3xx+ disasm

Merge the extra tracking that is useful for generating stats from asm
(as opposed to ir), and for guestimating things like inputs and outputs
(mostly useful for r/e) into ir3's version and drop cffdec's version.

There is a small change in disasm output for the decode tools, in that
it no longer prints the used consts, but rather just the max accessed
const.  This is the more useful piece of information, and avoids making
the shared regmask type big enough to deal with the const reg file.
Additional error checking for invalid regids causes crashdec to bail
out sooner when decoding memory that *might* hold valid instructions.
Also, crashdec no longer prints stats, because stats aren't very useful
when trying to decode random instruction memory (which might or might
not be valid instructions).

nir/lower_clip: make the pass compatible with Vulkan semantics

Vulkan allows fragment shaders to read gl_ClipDistance[], in which
case the SPIR-V compiler inserts a single compact array variable for
VARYING_SLOW_CLIP_DIST0 and the lowering should not try to inject
its own variables, but instead work in terms of the existing one.
Vulkan drivers are expected to call this with use_clipdist_array set
to true to be consistent with this setup.

radv: Fix uninitialized variable in renderpass.

Fixes some dEQP-VK.renderpass2.* flakes. Valgrind:

Why false?

A renderloop happens when the same attachment is both used as input
attachment and output (color, ds) attachment in a subpass. Of course
this doesn't happen outside of a renderpass and hence we can initialize
it to false at the start of the renderpass.

Track them via pending_flush_bits. Previously WFI was only tracked in
flush_bits and WAIT_FOR_ME was emitted directly. This means that we don't
emit WAIT_FOR_ME or WAIT_FOR_IDLE if there wasn't a cache flush or other
write by the GPU. Also split up host writes from sysmem writes, as only
the former require WFI/WAIT_FOR_ME.

Along the way, I also realized that we were missing proper handling of
transform feedback counter writes which require WAIT_MEM_WRITES. Plumb
that through as well. And CmdDrawIndirectByteCountEXT needs a
WAIT_FOR_ME as it does not wait for WFI internally.

As an example of what this does, a typical barrier for transform
feedback with srcAccess = VK_TRANSFORM_FEEDBACK_WRITE_COUNTER_BIT_EXT
and dstAccess = VK_ACCESS_INDIRECT_COMMAND_READ_BIT used to emit on

- WAIT_FOR_IDLE

nir/schedule: Add an option for a fallback scheduling algorithm

The current scheduling algorithm favors parallelism a bit too
aggressively and sometimes generates shaders that fail register
allocation. This happens even if the threshold is set to zero to force
it to always use the CSR instruction choosing algorithm.

This patch adds an option to use an even more aggressive fallback that
just always picks the instruction with the shortest maximum delay in the
hope that that will generate the least register pressure. The intention
is to use this as a last resort after register allocation fails in order
to at least have a working shader.

15 months agospirv: Rework our handling of images and samplers
Jason Ekstrand [Fri, 29 May 2020 21:45:21 +0000 (16:45 -0500)]
spirv: Rework our handling of images and samplers

Previously, objects of type OpTypeImage or OpTypeSampler were treated as
vtn_pointers and objects of type OpTypeSampledImage were a special-use
vtn_sampled_image struct.  This commit changes that so that all of those
objects are stored in vtn_ssa_values.  Each of images, samplers, and
sampled images, are stored as a scalar or vector nir_ssa_def whose
components are NIR deref values.  We now use vtn_type_get_nir_type to
re-resolve those as-needed into GLSL sampler types for NIR.

This simplification has a number of benefits:

 1. We can git rid of the rest of our special-cases for handling images
    and samplers in function arguments.  Now that they're treated as
    structs at the glsl_type level, the generic paths can handle images
    and samplers.

 2. We can now construct composite values containing images and samplers
    internally.  It's unclear from the SPIR-V spec whether or not this
    is allowed and it's not a pattern that GLSLang currently generates
    thanks to GLSL rules.  However, if we do start seeing SPIR-V that
    contains such composites, we should now be able to handle it.

 3. SPIR-V OpNull and OpUndef instructions can now create samplers,
    images, and sampled images.  The NIR generated won't likely be fully
    valid but, given a NIR pass to do something sensible, it should be a
    thing we can compile.
