AMD graphics card not supported?

[mattparks]

I did not know at the time of implementing push descriptors that some modern AMD cards did not support it. For now, I have disabled the usage of push descriptors. I can only test on an NVidia 960 and an NVidia 840M so any other AMD card issues pop up to let me know.

Now I got Unknown vulkan error -1000069000. From debbuger I can see that error is in this line:

DescriptiorSet.cpp:24

[mattparks]

What test are you running, and when your not running with the debugger what is the console full output? Also what does the call history look like before it hits the error.

[Sauler]

I'm running TestGUI, but this error is in all of them.
Full console output: https://pastebin.com/9XrRDrq0
Full call history:

In Renderer::CheckVk method result is set to VK_ERROR_OUT_OF_POOL_MEMORY.

There was an error that I fixed in 75b70b1 that would not allocate enough pool space in pipeline descriptor pools for the types used in the shader. I was not having any pool memory issues before or after making those changes so I cannot be sure if it worked; https://github.com/Equilibrium-Games/Acid/blob/master/Sources/Renderer/Pipelines/PipelineGraphics.cpp#L182 might be an issue if pool creation is too large.

It still does not work. Same error in same line.

[mattparks]

Can you tell me what driver you are using, also update to the latest driver. Have you tried to use any other Vulkan engines/demos? You might want to change the value in PipelineGraphics.cpp on line 182 (linked in my last comment) to a value under 128, 64 will still run for me, I am thinking the pool is not working correctly on AMD.

You might also want to debug what this line of code is providing to the descriptor pool: https://github.com/Equilibrium-Games/Acid/blob/master/Sources/Renderer/Pipelines/PipelineGraphics.cpp#L177
I am getting a list of pools that looks like this (from Font/Gui):

[Sauler]

I have newest driver. Vulkan examples that are shipped with SDK works fine.
Changing maxSets value does nothing.
I am getting same list as you.

[mattparks]

I was able to upgrade from my NVidia 960 to an AMD R9 390. For some reason on NVidia pipeline pool sizes did not matter when allocating, so I set each descriptor pool size to the max for each type in the pipeline. This was a quick hack to get it running, oddly has no memory/speed impact with having such a large count. I am also seeing some texture artifacts in Physics/PBR, something I am trying to fix now.

Ok it working now, thank you 👍
