Module build failure with 5.13.0

[da-phil]

I tried to install the amdgpu-dkms module on Ubuntu 20.4.3, first I failed due to the issue with compiler flags, which was solved in #117, but now I'm getting nasty conflicting types compile errors, like

I attached the whole build log: make.log

Which kernels are officially tested with this release? I couldn't find this information anywhere, but I suppose version 5.4 for Ubuntu 20.04.3?

Building the module worked for the following two Ubuntu kernels though:

• 5.11.0-42-generic
• 5.4.0-92-generic

I get the same conflicting types errors with amdgpu-dkms package version 5.11.32.40502-1350682.

I'm on kernel 5.13.0-22-generic. Have not tested with a 5.11 kernel or below.

I'm on kernel 5.13.0-22-generic. Have not tested with a 5.11 kernel or below.

I'm now on 5.11.0-42-generic and everything has been working smoothly, since creating the issue.
I think I remember AMD stating that supporting more kernels is a current work-in-progress.

Closing since gitlab ticket is open (and that's the right place for this issue)
