Running Project causes validation errors #57

Closed Silver-will closed 1 month ago

Silver-will commented 3 months ago

Error as seen here:

MessageID: VUID-vkCreateCommandPool-queueFamilyIndex-01937 1457732636
Message: Validation Error: [ VUID-vkCreateCommandPool-queueFamilyIndex-01937 ] | MessageID = 0x56e33c1c | vkCreateCommandPool: pCreateInfo->queueFamilyIndex is VK_QUEUE_FAMILY_IGNORED, 
but it is required to provide a valid queue family index value. 
The Vulkan spec states: pCreateInfo->queueFamilyIndex must be the index of a queue family available in the logical device device 
(https://vulkan.lunarg.com/doc/view/1.3.261.1/windows/1.3-extensions/vkspec.html#VUID-vkCreateCommandPool-queueFamilyIndex-01937)

I imagine this might be due to my GPU not supporting something used in the code?

theWatchmen commented 3 months ago

Possibly. We fixed some of the queue handling code a while back but maybe we missed a corner case. Which GPU are you using?

Silver-will commented 3 months ago

@theWatchmen The proper model is intel UHD Graphics Xe G4 48EUs

theWatchmen commented 3 months ago

It's an integrated graphics card which exposes only one queue. However I thought we had this case covered. Which line of code causes this error?

Closing for lack of reply. Feel free to re-open if needed.
