Good morning Alex,
Just one observation,

Hi,
I'm trying to get an understanding of the blob allocation and mapping
flow for virtio-gpu for Vulkan and Rutabaga. Having gotten all the
various libraries setup I'm still seeing failures when running a TCG
guest (buildroot + latest glm, mesa, vkmark) with:
./qemu-system-aarch64 \
-M virt -cpu cortex-a76 \
-m 8192 \
-object memory-backend-memfd,id=mem,size=8G,share=on \
-serial mon:stdio \
-kernel
~/lsrc/linux.git/builds/arm64.initramfs/arch/arm64/boot/Image \
-append "console=ttyAMA0" \
-device virtio-gpu-gl,context_init=true,blob=true,hostmem=4G \
-display sdl,gl=on -d
guest_errors,trace:virtio_gpu_cmd_res\*,trace:virtio_gpu_virgl_process_command
-D debug.log
which shows up as detected in dmesg but not to vulkaninfo:

WARNING: [Loader Message] Code 0 : terminator_CreateInstance: Failed to
CreateInstance in ICD 1. Skipping ICD.
a common problem I have when testing different mesa builds is not
declaring the intended driver each time. I could be getting errors like
yours but if I set the VK_ICD_FILENAMES env var to the correct driver
manifest (the installed icd.d/virtio-*.json file from my mesa build) the
device is properly recognized. Might be unrelated to this error, but
still it helps to define it explicitly each time.
error: XDG_RUNTIME_DIR is invalid or not set in the environment.

With an older and more hacked up set of the blob patches I can get
vulkaninfo to work but I see multiple GPUs and vkmark falls over when
mapping stuff:
