As of yesterday PanVK is now advertising Vulkan 1.1 support rather than Vulkan 1.0, but it's not yet a fully conformant driver. The expectation though is that more tests are running now with Vulkan 1.1 support exposed. The merge request by Eric Smith of Collabora argues:
"We know we have a broken Vulkan driver, so it's debatable whether it's a broken Vulkan 1.0 or broken 1.1. Advertising 1.1 lets us run more tests, and this patch does this. It also turns on `imageCubeArray` and `fragmentStoresAndAtomics`, which again lets us run more tests.
...
There's still a couple of optional vk 1.1 and required vk 1.0 features we're missing, but exposing vk 1.1 doesn't make that bit any worse."
That code is now in Mesa 25.0-devel and we'll see how well polished the Vulkan 1.1 support is for PanVK by the time Mesa 25.0 stable ships in mid-Q1.
