AMD Open-Source Driver For Vulkan "AMDVLK" Is Now Available

[M@yeulC]

I would be curious to see the performance of various parts of the drivers, if AMDVLK and RADV are made to be interoperable.

By the way, here's an idea: provide an equivalent to GALLIUM_HUD inside the libvulkan

This seems like an issue with the C++ standard (C++11 vs. C++14, perhaps). Could you file an Issue on the GitHub project? Thanks!

Noticed a few minutes ago someone else already opened an issue about it: https://github.com/GPUOpen-Drivers/pal/issues/1

This PAL sounds like Gallium 2.0.

Well, Gallium has much more code sharing / driver agnostic where as PAL is all very hardware-specific with a low-level API on top, so not exactly Gallium-like per se.

I will be having AMDVLK vs. RADV on the same kernel today~tomorrow.

this is very interesting
i am going to build a pc with desktop raven ridge around february so i expect by then everything is upstream

Very nice, just in time before Christmas.
Looking very much forward to a comparison of both drivers.

Compiles with some patches: https://aur.archlinux.org/packages/amdvlk-git/

I'm on drm-next-4.16-wip and vulkaninfo works

$ vulkaninfo | grep deviceName
WARNING: radv is not a conformant vulkan implementation, testing use only.
deviceName = AMD RADV POLARIS10 (LLVM 6.0.0)
deviceName = AMD Radeon (TM) RX 480 Graphics

but real applications do not:

$ VK_ICD_FILENAMES=/etc/vulkan/icd.d/amd_icd64.json vkmark
Error: VULKAN_HPP_NAMESPACE:evice::createSwapchainKHR: ErrorInitializationFailed

EDIT: WRONG. IT WORKS. IT WAS MODESETTING THAT'S BROKEN!

It's great that the code has finally dropped but it would have been nice if someone had tried compiling it first...

Vulkaninfo says RADV all over so it doesn't look like you have AMDVLK set up properly?

Did you try the supported distributions? 😃
