Description

This extension enables support for a new class of group operations on subgroups via the GL_NV_shader_subgroup_partitioned GLSL extension and SPV_NV_shader_subgroup_partitioned SPIR-V extension. Support for these new operations is advertised via the VK_SUBGROUP_FEATURE_PARTITIONED_BIT_NV bit.

This extension requires Vulkan 1.1, for general subgroup support.

Promotion to VK_EXT_shader_subgroup_partitioned

All functionality in this extension is included in VK_EXT_shader_subgroup_partitioned, with the suffix changed to EXT. The original type, enum, and command names are still available as aliases of the core functionality.
