2D Block Array Capabilities

Warning

Experimental features:

• May be replaced, updated, or removed at any time.

• Do not require maintaining API/ABI stability of their own additions over time.

• Do not require conformance testing of their own additions.

Motivation

Some Intel GPU devices support 2D block array operations which may be used to optimize applications on Intel GPUs. This extension provides a device descriptor which allows to query the 2D block array capabilities of a device.

Support

Adapters which support this experimental feature must return UR_RESULT_SUCCESS from the urDeviceGetInfo call with the new UR_DEVICE_INFO_2D_BLOCK_ARRAY_CAPABILITIES_EXP device descriptor.
