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 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.

VkPhysicalDeviceShaderCoreBuiltinsPropertiesARM - Structure describing shader core builtins properties supported by an implementation

Description

If the PhysicalDeviceShaderCoreBuiltinsPropertiesARM structure is included in the pNext chain of the PhysicalDeviceProperties2 structure passed to getPhysicalDeviceProperties2, it is filled in with each corresponding implementation-dependent property.

VkPhysicalDeviceShaderCoreBuiltinsFeaturesARM - Structure describing the shader core builtins features that can be supported by an implementation

Members

This structure describes the following feature:

Description

If the PhysicalDeviceShaderCoreBuiltinsFeaturesARM structure is included in the pNext chain of the PhysicalDeviceFeatures2 structure passed to getPhysicalDeviceFeatures2, it is filled in to indicate whether each corresponding feature is supported. If the application wishes to use a Device with any features described by PhysicalDeviceShaderCoreBuiltinsFeaturesARM, it must add an instance of the structure, with the desired feature members set to TRUE, to the pNext chain of DeviceCreateInfo when creating the Device.
