11b96a84b0 brw: Call nir_opt_algebraic_late later in brw_postprocess_nir_opts
Move the call to nir_opt_algebraic_late after the last time
brw_nir_optimize might be called. nir_opt_algebraic_distribute_src_mods
works together with the late algebraic optimizations, so move it also.

fd29183901 elk: Use F16TO32 for nir_op_f2f32 of float16 source
This matches the behavior of nir_op_unpack_half_2x16_split_x. Gfx7
uses a special opcode for this conversion. Fixes numerous assertion
failures in shader-db on Ivy Bridge and Haswell.

I am not sure why this was never encountered previously.

This was incorrect for OpenCL due to the possibility of variable shared memory
existing despite shared_size == 0. Fortunately the optimization it was trying to
do should be done in NIR via nir_opt_barrier_modes so we can just drop the brw
code and move on with our merry lives. Fixes OpenCL tests on Iris:

c6bbf6dff4 anv: rework descriptor set indexing in NIR
We're currently using 2 address formats for accessing descriptor
buffers (regardless of whether EXT_descriptor_buffer is used).
nir_address_format_64bit_global_32bit_offset is used with bindless
shaders or nir_address_format_32bit_index_offset otherwise.

When using nir_address_format_32bit_index_offset, the layout pass
insert vec2(surface, offset) values in the shader to access the
descriptor buffers. With surface being the binding table entry of the
descriptor. The binding table is packed and might also contain render
targets so there is no equality mapping between the binding table
index and the descriptor set index. For example with we could have a
binding table like this :
   - BT0 : render target 0
   - BT1 : render target 1
   - BT2 : descriptor buffer 0
   - BT3 : descriptor buffer 4

In the next commit we will stop using a binding table entry to access
descriptor buffers on Gfx12.5+ and we will need the descriptor set
index access the descriptor data.

So in this commit we introduce a remapping in NIR to do the descriptor
set index to binding table entry mapping. The mapping table is a vec8
put at the beginning of the functions and the value from the vector is
extracted when loading data from the descriptor buffer

Given a situation like this :

  - CB_B: begin, computeA, barrier (depth), computeB, end

The depth cache is not being flushed between renderDepthA & computeB
because :
  - it's not flushed at the end of CB_A (it's not required)
  - when CB_B starts, we're still on GFX pipeline mode but do not
    flush render caches because pipeline mode is unknown
  - when barrier is CB_B is executed, we're already in compute
    pipeline mode and HW cannot flush depth.

The fix is to flush RT/depth cached when switching from unknown
pipeline mode any pipeline mode.

b06d759a93 intel: Add virtio-gpu native context
Add virtio-intel native DRM context base preparatory code. Virtio-intel
works by passing ioctl's from guest to host for execution, utilizing
available VirtIO-GPU infrastructure.

This patch adds initial experimental native context support using i915
KMD UAPI.

Compile Mesa with -Dintel-virtio-experimental=true to enable virtio-intel
native context support.
