## 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.

## New Enum Constants

- `VK_NV_SHADER_SUBGROUP_PARTITIONED_EXTENSION_NAME`

- `VK_NV_SHADER_SUBGROUP_PARTITIONED_SPEC_VERSION`

- Extending VkSubgroupFeatureFlagBits:

  - VK_SUBGROUP_FEATURE_PARTITIONED_BIT_NV
