Hi Tommy,
Unfortunately NIR is a bit lacking for documentation, save for comments
in src/compiler/nir/nir_intrinsics.py. For Vulkan ones, the best bet is
likely looking at spirv_to_nir (src/compiler/spirv/) and seeing what
generates it, and working up from there.
Debug strategy varies per driver
Hi Tommy,
As you've probably noticed already, Mesa documentation is sparse at
best. For NIR, the best places to go are:
1. For ALU ops, nir_opcodes.py defines the opcodes as well as a C
snippet which describes the opcode's semantics
2. For all intrinsics, nir_intrinsics.py defines them and typ
Hi,
Could I get some tips on figuring out what the NIR intrinsics
do, specifically the vulkan related ones? Also, what is the debug
strategy that is used to debug NIR shaders to check if the implementation
is correct?
Thanks,
Tommy
