If an extensions that you need is not exposed in ash leave a comment, and I will add it to the list.

If you would like to implement some extensions but you don't how, have a look at the currently exposed extensions. Otherwise don't hesitate to ask, help is always appreciated.

[msiglreith]

Would it make sense to also add some 'hidden' extensions (ie VK_AMD_gpa_interface or VK_AMD_wave_limits), which are not really specified at this point?

[MaikKlein]

@msiglreith I am fine with experimental extensions. They would have to live inside the extension itself because vk.rs is generated.

I think we should create a new module extensions::experimental::amd::Foo. Semver is then ignored for those extensions.

[msiglreith]

Sounds good! I will try to collect all the necessary information to define the API as I want to play a bit with the gpa_interface extension

[gwihlidal]

I've been working on the VK_NV_ray_tracing support now, and likely also VK_EXT_descriptor_indexing

@MaikKlein There's a useful new extension I'd love to see: VK_KHR_timeline_semaphore
