Subject: anv/device: GetDeviceQueue2 should only return queues with matching flags
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=b262f17b159141fb21c60971d21b884dcd226152;p=mesa.git

anv/device: GetDeviceQueue2 should only return queues with matching flags

From the Vulkan 1.1 spec, VkDeviceQueueInfo2 structure:

   "The queue returned by vkGetDeviceQueue2 must have the same flags value
    from this structure as that used at device creation time in a
    VkDeviceQueueCreateInfo instance. If no matching flags were specified
    at device creation time then pQueue will return VK_NULL_HANDLE."

For us this means no flags at all since we don't support any.
