• VK_KHR_multipass
• Tessellation winding order
• ... and probably some more

Also useful for repro purposes, sending 1000+ shaders where only 1 is failing is not efficient.

PDF2 has a lot of pNext structures, and it's the new way to enable features in Vulkan 1.1. We'll probably need to enable all of them somehow to be able to replay Vulkan 1.1 pipelines accurately.

It might be useful to extract only pipeline information necessary for a draw call from a capture for purposes of making reduced repro cases.

Ideally, it should be possible to set up a mini-benchmark for most pipelines using "dummy" data in an automated fashion. This could then ideally be used for perf-regression tracking or analyzing if spirv-opt actually makes a difference.

Sometimes you'd have the SPIR-V that's failing, but ideally we need to figure out all pipelines which this SPIR-V belongs to so we can narrow down the search.

fossilize-disasm only supports SPIR-V disasm currently, introspecting all state in a clean way would be nice to have as well.

For a repro capture it might be necessary to have particular extensions or features enabled.
Currently, the serialization format does not have a way to encode these things.

Ideally, this shouldn't be relevant, but who knows.

Being able to capture in segfaults is useful. We'll need something similar for Windows.
