Description
When using pipeline libraries in ray tracing pipelines, a library might get linked into different pipelines in an incremental way. An application can have a strategy where a ray tracing pipeline is comprised of N pipeline libraries and is later augumented by creating a new pipeline with N + 1 libraries. Without this extension, all group handles must be re-queried as the group handle is tied to the pipeline, not the library. This is problematic for applications which aim to decouple construction of record buffers and the linkage of ray tracing pipelines.
To aid in this, this extension enables support for querying group
handles directly from pipeline libraries. Group handles obtained from a
library must remain bitwise identical in any
Pipeline that links to the library.
With this feature, the extension also improves compatibility with DXR 1.1 AddToStateObject(), which guarantees that group handles returned remain bitwise identical between parent and child pipelines. In addition, querying group handles from COLLECTION objects is also supported with that API.

data PhysicalDevicePipelineLibraryGroupHandlesFeaturesEXT Source #
VkPhysicalDevicePipelineLibraryGroupHandlesFeaturesEXT - Structure describing whether querying shader group handles from a pipeline library is supported by the implementation
Members
This structure describes the following features:
Description
If the PhysicalDevicePipelineLibraryGroupHandlesFeaturesEXT structure
is included in the pNext chain of the
PhysicalDeviceFeatures2
structure passed to
getPhysicalDeviceFeatures2,
it is filled in to indicate whether each corresponding feature is
supported. PhysicalDevicePipelineLibraryGroupHandlesFeaturesEXT can
also be used in the pNext chain of
DeviceCreateInfo to selectively enable these
features.
