public final class ARMShaderCoreBuiltins
extends Object

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 optimization purposes. A typical optimization 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.
