Re: [PATCH 0/1] MR5787: winevulkan: Use an internal NtUser call to retrieve a GPU LUID.

[Rémi Bernon]

There's actually several issues with it:

1) First is related to how win32u vulkan driver is used a bit elsewhere, from winex11 XRandR and from d3dkmt. They use `vkGetPhysicalDeviceProperties2` and hooking it in win32u creates a cycle which requires a bit of refactor to break up. It's not too bad and it could actually be a good thing to do... however:

2) `vkGetPhysicalDeviceProperties2` is an instance function and needs to be queried with an instance. We don't have a way to hook such functions and dispatch it to the right instance in our win32u interface. This is a bigger problem and I don't see an easy way to solve it.
