Description
Required for testing of sampler feedback operations (`WriteSamplerFeedback`, `WriteSamplerFeedbackLevel`) using FeedbackTexture2D and FeedbackTexture2DArray resources.
Current Status: No feedback texture infrastructure exists. IIUC, Vulkan does not have any extension support for sampler feedback.
The first step will be to refine the following acceptance criteria for refinement/estimation. It will also establish a plan (or lack of) for this functionality with SPIRV.
AC:
- [ ] Query for `SamplerFeedbackTier`
- [ ] Define the `FeedbackTexture2D` / `FeedbackTexture2DArray` resource kinds
- [ ] Allow YAML test config to initialize a texture of this sort
- [ ] DX: Add a function to create the feedback resource
- [ ] DX: Implement feedback texture readback
- [ ] VK: TBD
- [ ] Add independent testing of functionality

Research direction
The issue names no files or tests. Start by refining the acceptance criteria around SamplerFeedbackTier, feedback texture resource kinds, YAML initialization, DirectX creation and readback, Vulkan status, and independent testing; done means an agreed implementation plan or an explicit decision that the functionality is not currently feasible.
