Description Kristy-Leigh Minehan 2016-10-05 05:38:33 UTC 
Voltage settings written to the SysFS entry pp_table do not apply - if they're modified in the VBIOS, however, they do.

That's the vaguest subject ever :)

Please use the specific mailing list for the subsystem you are having a
problem with to notify them of this issue, or refine the fields in this
bug report to point to it, sysfs itself is just a transport for all
drivers, it is not very specific.

This is in reference to the AMDGPU driver - when writing to /sys/class/drm/card0/pp_table, for example, clocks are applied correctly, the TDP/TDC/Max Power Delivery Limit is applied - but voltages are not.

Great, please contact those driver authors on the
dri-devel@lists.freedesktop.org mailing list.
