5 years agonvc0/ir: always use CG mode for loads from atomic-only buffers

nvc0/ir: always use CG mode for loads from atomic-only buffers

Atomic operations don't update the local cache, which means that we
would have to issue CCTL operations in order to get the updated values.
When we know that a buffer is primarily used for atomic operations, it's
easier to just avoid the caching at that level entirely.

The same issue persists for non-atomic buffers, which will have to be
fixed separately.

Fixes the failing dEQP-GLES31.functional.atomic_counter.* tests.

nvc0: add support for handling indirect draws with attrib conversion

The hardware does not natively support FIXED and DOUBLE formats. If
those are used in an indirect draw, they have to be converted. Our
conversion tries to be clever about only converting the data that's
needed. However for indirect, that won't work.

Given that DOUBLE or FIXED are highly unlikely to ever be used with
indirect draws, read the indirect buffer on the CPU and issue draws
directly.

5 years agopanfrost: Implement Midgard shader toolchain

panfrost: Implement Midgard shader toolchain

This patch implements the free Midgard shader toolchain: the assembler,
the disassembler, and the NIR-based compiler. The assembler is a
standalone inaccessible Python script for reference purposes. The
disassembler and the compiler are implemented in C, accessible via the
standalone `midgard_compiler` binary. Later patches will use these
interfaces from the driver for online compilation.

st/mesa: Set pipe_image_view::shader_access in PBO readpixels.

Commit 8b626a22b24089edf90cb1b06e5b1895bb36c61b introduced a new
pipe_image_view::shader_access field, indicating the access mode
specified in the shader.  st/mesa's built-in PBO download shader
creates a write-only image buffer, so we should flag it as such.

Nobody uses this field yet (Iris will), so we don't need to backport
this fix to stable branches.
