render-graph-validator

Render graph resource lifetime validation checks that resources are not used before creation or after destruction. It inspects pass dependencies and barrier insertion to ensure safe resource flows across the graph.

Barrier correctness verification examines pass dependency tracking with VK_KHR_dynamic_rendering and Synchronization2 usage. It validates that synchronization primitives are inserted properly between render passes to prevent hazards.

ExternalImage and ExternalBuffer validation checks correct handling of initial and final layouts, transitions, and current resource states. It ensures external resources maintain proper layout consistency throughout the render graph.

Resource creation order errors occur when passes reference resources before they are created or after they are destroyed. The validator enforces correct creation ordering and execution registry integrity to identify these issues.

Yes, the validator is designed for the Vulkan-based Katla engine to debug render graph issues. It provides end-to-end validation guidance and helps identify common pitfalls when implementing new render passes.

Common barrier pitfalls include incorrect dependency tracking, missing synchronization between passes, and improper external resource layout transitions. The validator identifies these issues by checking execution registry integrity and barrier correctness.
