            Bug ID: 92993
           Summary: Powerplay: Thermal controller fails to start on R9
                    Nano (Fiji)
           Product: DRI
           Version: DRI git
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/AMDgpu
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: master.homer@gmail.com

Just got a Sapphire R9 Nano and noticed some problems while running with the
latest powerplay kernel from agd5f (commit
256ca780500bc445752763f32b246dc9ee396b62). I don't know how well implemented
this is just yet, but it seems like the thermal controller fails to start on my
card due to hwmgr->start_thermal_controller->function_list being NULL:
[    2.057417] powerplay: phm_start_thermal_controller
[    2.057419] [ powerplay ] phm_dispatch_table Invalid Parameter!
ffff880425cd2000 ffff880425cd2230           (null)

The first address refers to hwmgr, the second to rt_table and the last to
rt_table->function_list.
This, in turn, causes the hwmon interface to not work, and sensors gives me a
0.0 temperature. I'm unsure if this causes the fan to not speed up, but I
haven't noticed any sound difference when running valley for example.

I've noticed another (possibly unrelated) thing too, checking amdgpu_pm_info I
can see that the mclk never changes, just the sclk. I did notice that it fails
to find the virtual voltage 65281 in the vdd list, but of course I'm not sure
this is related:
[    2.006036] powerplay: us_vdd 900 vs virtual_voltage_id 65281
[    2.006037] powerplay: us_vdd 65282 vs virtual_voltage_id 65281
[    2.006038] powerplay: us_vdd 65283 vs virtual_voltage_id 65281
[    2.006038] powerplay: us_vdd 65284 vs virtual_voltage_id 65281
[    2.006039] powerplay: us_vdd 65285 vs virtual_voltage_id 65281
[    2.006040] powerplay: us_vdd 65286 vs virtual_voltage_id 65281
[    2.006040] powerplay: us_vdd 65287 vs virtual_voltage_id 65281
[    2.006041] powerplay: us_vdd 65288 vs virtual_voltage_id 65281
[    2.006042] Can't find requested voltage id in vdd_dep_on_sclk table!
