Title: GPU drivers missing vulkan support
Dear Firefly
I'm attempting to test the RK3588 Mali GPU using vulkan API on Ubuntu 20.04 LTS using Firefly Linux SDK, but the vulkan ICD loader is failing. By investigation I find no vulkan symbols in the libmali library provided by Firefly (git.t-firefly.com:8022/rk-linux/external/libmali)

$ grep vk_icd libmali-valhall-g610-g6p0-*
#no match

Example from other drivers (this is Odroid N2+ userspace from arm.com)
$ grep vk_icd libmali.so.0.39.0
grep: libmali.so.0.39.0: Binary file matches

Please recompile/update your Mali-G610 GPU libmali userspace drivers with vulkan support enabled. It is a vital feature.

Thank you

Please provide the log of the failure of the vulkan ICD loader.

$ vulkaninfo
ERROR: [Loader Message] Code 0 : loader_scanned_icd_add: Attempt to retrieve either 'vkGetInstanceProcAddr' or 'vk_icdGetInstanceProcAddr' from ICD libmali.so failed.
Cannot create Vulkan instance.
This problem is often caused by a faulty installation of the Vulkan driver or attempting to use a GPU that does not support Vulkan.
/build/vulkan-tools-_ynL0i/vulkan-tools-1.2.131.1+dfsg1/vulkaninfo/vulkaninfo.h:371: failed with ERROR_INCOMPATIBLE_DRIVER

So the vulkan ICD loader is looking for specific vk* symbols in the GPU userspace library, but they are not there. I have checked all the relevant libraries and they are completely missing. So the problem is not the loader but the GPU driver libraries. The libmali libraries have not been compiled with vulkan support enabled.

I also encountered the same error. And I solved it. You can read more information at GunSpin site.

Hopefully, Firefly will update lib mali to support Vulkan soon, as this is an essential feature for anyone agario who wants to get the most out of the GPU power on the RK3588
