Bug ID: 50542
Summary: get_gpu_properties_from_vulkan() assumes a 1-1 mapping
of XRRProvider to VkPhysicalDevice
Product: Wine
Version: unspecified
Hardware: x86-64
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: winex11.drv
Assignee: wine-bugs at winehq.org
Reporter: loothelion at nvidia.com
Distribution: ---
The function currently takes in a single XRRProvider, and will stop execution
after it finds the first eligible device. This causes an issue for setups where
multiple Vulkan ICDs may expose devices which have valid RROutputs on a single
XRRProvider.
I believe a minimal test-case for this would be the LUID part of the vulkan-1
test already in the WINE tree, as it enumerates LUID information for every
VkPhysicalDevice it can find.
