This is dedicated heap memory allocations approach.
This type of blob should be used in the following way:
1) Guest virtio-gpu driver on start checks for dedicated memory region.
2) On create_blob drm ioctl guest driver reserves chunk of required memory and
send it to host using sg list. Heap is managed on guest.
3) Device creates dmabuf fd from this sg entry and sends it to virglrenderer on
create_blob virtio-gpu command. Blob is created using
virgl_renderer_resource_import_blob call.
4) On next vkAllocateMemory call from mesa, virglrenderer will allocate vk memory
handle from this dmabuf fd. It will receive resource id in
VK_STRUCTURE_TYPE_IMPORT_MEMORY_RESOURCE_INFO_MESA vkAllocateMemory structure.
The flow is opposite to the way it's done for HOST_3D types of blob, where
vkAllocateMemory is called first, vk memory is allocated from random host place.
Then create_blob is called, where dmabuf fd is exported from VkDeviceMemory.

To support an extension, we need venus-protocol support and vkr support.

Temporarily disable the old CI configuration file and replace it with
the one belonging to the reworked CI infrastructure.
The project CI/CD settings should be updated in order to switch
'CI/CD configuration file' from 'ci/.gitlab-ci.yml' to the default
'.gitlab-ci.yml', for consistency with Mesa CI.
Note the 'ci/' folder becomes obsolete in favor of '.gitlab-ci/' and
could be removed once all needed functionality has been migrated to the
new setup.

Using a pointer for fs_info in the shader key is not really that useful
because the contents of the structure can change even though the pointer
remains the same, and the pointer can be different when the contents are

This is a fix for segfault issue, because of usage of uninitialized
vkQueue handle.
Spec [1] states that vkGetDeviceQueue must only be used to get queues
that were created with the flags parameter of VkDeviceQueueCreateInfo
set to zero. To get queues that were created with a non-zero flags
parameter use vkGetDeviceQueue2.
The problem that in case queue was created with flags set to zero following
vkGetDeviceQueue2 call will fail. By failing I mean that pQueue set to NULL,
which later leads to segfault.
This problem was also reported by vulkan validation layer:
vkr: vkGetDeviceQueue2: value of pQueueInfo->flags must not be 0. The Vulkan
spec states: flags must not be 0
