Description
This extension provides the ability to determine device-specific properties on Arm GPUs. It exposes properties for the number of shader cores, the maximum number of warps that can run on a shader core, and shader builtins to enable invocations to identify which core and warp a shader invocation is executing on.
This extension enables support for the SPIR-V CoreBuiltinsARM
capability.
These properties and built-ins can be used for debugging or performance
optimisation purposes.
A typical optimisation example would be to use CoreIDARM
to select a
per-shader-core instance of a data structure in algorithms that use atomics
so as to reduce contention.
