## Description

This extension adds support for a new type of pipeline, data graph pipelines, that provide an encapsulation construct for computational graphs operating on full resources (e.g. ML/AI graphs, image processing pipelines, etc). This extension only supports tensor resources and does not define any operations that can be used within those graphs. These operations will be defined by separate extensions.

## New SPIR-V Capabilities

## Issues

1) Should graph pipeline resource info structures be integrated into pipeline layouts? Would a new graph pipeline layout be a better fit?

RESOLVED: Graph pipeline resource info are passed separately at pipeline creation time.

2) Do we need a new shader stage for graph pipelines for use in creating descriptor set layouts?

RESOLVED: Currently using VK_SHADER_STAGE_ALL.

3) Should this extension provide applications with a way of knowing which combinations of sparsity information implementations can take advantage of when processing graph constants?

RESOLVED: No. Describing the exact combinations is in some cases complex and it is always valid for implementations to ignore the sparsity information and treat the data as dense. Specific implementations can provide guidance to application writers if they so desire and applications are encouraged to always provide sparsity information that they have.
