[Bug 106188] Can't successfully set pstates in pp_od_clk_voltage

However, I am still not able to raise the maximum allowed power consumption of the GPU. It's clear that "/sys/class/drm/card0/device/hwmon/hwmon0/power1_cap" sets the actual power limit and thus I need to raise it. But the problem is:

• I can't set it higher than power1_cap_max, only values below work.
• power1_cap_max equals to power1_cap, so raising power consumption is

actually completely forbidden

• Despite of being root, I don't have write access to power1_cap_max, unlike

to power1_cap

The max supported power cap is defined by the OEM in a vbios table and we limit the max to that value. power1_cap_min and max are RO so you can't change them. They define the range of available values.
