This extension introduces a new semaphore type that uses an integer payload to identify a point in a timeline. The extension supports querying the semaphore, host wait/signal operations, and device wait/signal operations.
VK_KHR_shader_clock
This extension allows a shader to query a real-time or monotonically incrementing counter at the subgroup level or across the device level.
VK_KHR_shader_subgroup_extended_types
This extension enables the nonuniform group operations in SPIR-V to support 8-bit integer, 16-bit integer, 64-bit integer, 16-bit floating-point, and vectors of these types.
VK_KHR_pipeline_executable_properties
This extension allows debugging and performance tools and applications in general to query properties and statistics about the pipeline compilation process.
VK_KHR_spirv_1_4
This extension allows the use of SPIR-V 1.4 shader modules, which in turn allows easier translation from high level languages into spirv.
VK_EXT_subgroup_size_control
This extension enables an implementation to control the subgroup size by allowing a varying subgroup size and also specifying a required subgroup size. The optional feature to allow full compute subgroups is enabled.
Clustered Subgroup Operations
This feature bit allows invocations to perform cluster operations such as add, mul, min, max, and, or, xor among partitions of a subgroup. The operations are only performed within the subgroup invocations within a partition.
