Could you tell me more about the fence problem? Is the vulkan driver broken with stock linux-4.7? Is it gpu dependant?
I usually test the driver with the tri/cube demos from the vulkan sdk, but I guess that might not be sufficient (I don't think either uses fences). I just tried the smoketest from the sdk, and there's definitely something wrong with it. I'm still investigating that...

Ok, so:
demos git:(97e3b67) ./smoketest -v
Swapchain: vkCreateSwapchainKHR() called with a non-supported pCreateInfo->imageArrayLayers (i.e. 1). Minimum value is 1, maximum value is 0.
Swapchain: vkCreateSwapchainKHR() called with a non-supported pCreateInfo->imageArrayLayers (i.e. 1). Minimum value is 1, maximum value is 0.
ParameterValidation: vkWaitForFences: returned VK_ERROR_INITIALIZATION_FAILED, indicating that initialization of an object has failed
terminate called after throwing an instance of 'std::runtime_error'
what(): VkResult -3 returned
[1] 6475 abort (core dumped) ./smoketest -v
(The imageArrayLayers error is a bug in the driver, and has been acknowledged by AMD.)
I assume the vkWaitForFences error is what you were talking about? I was really hoping to sidestep the dkms driver with linux-4.7, but I guess it's not all upstream yet.

Try to compile and run vkQualke(https://github.com/Novum/vkQuake) for example. Also try amdgpu_test from libdrm-amdgpu-pro-tools. Here is another bug about this problem when using open source kernel driver:
ValveSoftware/Dota-2-Vulkan#154

Ok, thanks for that. Sounds like the same problem I was seeing. I guess we'll have to get amdgpu-pro-dkms working.
If you can do a PR, let me know, otherwise I'll start with what you posted above.
There's also amdgpu-pro-firmware to worry about. I just checked, and the conflicting firmware binaries don't match what's in linux-firmware. Did you test with amdgpu-pro-firmware or just linux-firmware?
I guess I'll take a look at other firmware packages for ideas.

Just use my notes, I am not sure how to integrate the rest of the info in PKGBUILD file. Maybe some of the patches need to be Arch specific.
Now I have another problem: the compiled amdgpu.ko freezes my system when I try to start xorg.
I am using rx480, not sure if the problem would occur with other cards.

Did you install amdgpu-pro-firmware?
I had a look at the firmware loading docs: https://github.com/torvalds/linux/blob/master/Documentation/firmware_class/README
We should be able to install the firmwares in /lib/firmware/updates to avoid collisions with linux-firmware. There's also the firmware_class path, but you can only set one of those, so it's probably not a good idea.

Yep, tried with amdgpu-pro-firmware, also with stock linux-firmware package as well as with linux-firmware-git for AUR.

Also, after installing amdgpu-pro-dkms, dkms builds amdgpu.ko, not amdgpu.ko.gz, but the old amdgpu.ko.gz is loaded by default. I had to manually delete it.

So are you still getting hangs on Xorg startup? If so, is it the whole system or is Xorg just failing to start? Anything interesting in logs?

I did the changes needed to put the firmwares in /updates/ and get the dkms module building in #14.
Now I'm getting a kernel crash when starting X:

Does this look like yours?
I'm done for the day, but my next steps will be to see if the gentoo guys (or anyone else) has seen this, and if they've actually got it working on 4.7. Then I'll try to debug it directly.

Couldn't get the logs, I am still working on fixing the journald configuration. I didn't get any output when xorg crashed, it just stopped reacting to keyboard.
After I loaded amdgpu-pro amdgpu.ko, I got a crash dump while trying to run amdgpu_test. I think the output was different, I will try it again later today when I return from work.

Good news. I have a working Xorg after setting amdgpu.dal=0. The vulkan smoketest also passes now.
Could you let me know if that works for you?
