The merge window is over and the first release candidate to Linux 4.10 is now available for testing...

Does anyone have some first-hand experience how good the GCN 1.0 support is with 4.10 together with AMDGPU-PRO?
The one time I tried 4.9 with AMDGPU-PRO on my 280X, some Wine games crashed after a couple of minutes and some native steam games outright refused to launch.

I'm testing it right now, I will let you know in the next couple of days.

Does everyone clearly understand that 4.9 or 4.10 with AMDGPU-PRO is not a supported combination, that the AMDGPU-PRO kernel driver will fail to install, and that the upstream kernel does not include all of the functionality required for the closed-source userspace drivers ? Just checking...

The AMDGPU-PRO kernel driver will not normally install/function on a 4.8-or-higher kernel, so if you are talking about a configuration like that please make it clear whether you are using the upstream kernel or a hacked version of the AMDGPU-PRO kernel.

I like it when you try combinations like this, just worry about unsuspecting users thinking they are supported (or expected to work) and running into problems.

I will make everything clear, don't worry. I can already anticipate that performance with 4.10 is not satisfying with every workload, but I managed to get it up to 400% faster.

Lm-sensors (3.4 in Debian Unstable) is not reading my coretemp or nct6775 modules for my Z170, although the modules themselves appear to be loading according to /proc/modules.

Yes, "sensors" isn't working for me either. More fundamentally. "rdmsr" isn't working. It works fine with kernel 4.9, and I have switched back and forth between kernel 4.9 and 4.10-RC1 several times now. In an attempt to avoid it, I'm searching for any information before I begin a kernel bisection.

The guilty commit is:

dc280d93623927570da279e99393879dbbab39e7 is the first bad commit

    cpu/hotplug: Prevent overwriting of callbacks

And it was fixed almost right away. So, if I include the next 3 commits after the 4.10-rc1 tag, then everything is O.K.

0dad3a3 x86/mce/AMD: Make the init code more robust
b9d9d69 smp/hotplug: Undo tglxs brainfart
b4b8664 arm64: don't pull uaccess.h into *.S

On the plus side, my amdgpu sensor now also reads fan speeds.
