    I guess pro mostly depends on situation in Ubuntu 16.10

    That Ubuntu should use 4.8 kernel AFAIK, but what dkms module pro will ship at the time is yet to be seen, etc...

    The AMDGPU overclocking support would be the main end-user feature for Linux 4.8 when it comes to Radeon/AMDGPU.
    I guess that means, everybody should overclock their chips now But first all developers and then testers

    Well Michael, you can test it fine with your cards... if it moves - it works, if it burns - it works

    Indeed the _k suffix microcodes solved stability issues on my R9 390. The remaining issue is that mclk adjustments are causing monitor flickering, so I am forcing mclk to be locked to either the low frequency or the high frequency.

    Ah OK, so for 3xx series goes _k otherwise non _k for older.

    The new SMC ucode works with newer chips; previous ucode still recommended for older chips. Basically 290 vs 390 AFAICS.

    The chips have an internal revision number that we use to determine the appropriate ucode.

    Why suffix, do we need both _k and non k to be available ?

    Note that drm-next requires a merge with drm-fixes for stability on polaris cards as all of the polaris fixes have been going to the fixes tree.
