Vulkan - 9060XT on EGPU - Unable to allocate vkBuffers on device local memory, only host memory

[DerChris173]

Good day!
I'm using a 9060 XT-based product as an EGPU on an USB4 interface.
OS: Windows 11.
Driver version: Adrenalin 26.2.1

I'm attempting to allocate a vkBuffer, and none of the available memory types for this operation is on device local memory. Only host memory types are offered. It seems to work fine when allocating vkImages.
I've written a small application to verify this. Here's the output. I'm happy to attach source and binary of the test application if it is of help.

I believe this issue is resolved with 26.3.1. Thank you!

Hi @DerChris173,

Happy to hear your issue was resolved. If you're happy to, it would be good to get your source code so I can reproduce the issue and confirm the fix, and it would aid future AMD support. Many thanks,

There you go, as a CMAKE-Project:

I wrote it with Claude, so some of the comments and stuff ended up in German, but it hope it's useful toyou!
