This extension introduces the ability to back uniform blocks directly with descriptor sets by storing inline uniform data within descriptor pool storage. Compared to push constants this new construct allows uniform data to be reused across multiple disjoint sets of drawing or dispatching commands and may enable uniform data to be accessed with fewer indirections compared to uniforms backed by buffer memory.

Promotion to Vulkan 1.3

Functionality in this extension is included in core Vulkan 1.3, with the EXT suffix omitted. The original type, enum and command names are still available as aliases of the core functionality.

Vulkan 1.3 adds additional functionality related to this extension in the form of the maxInlineUniformTotalSize limit.
