<pre>Attempting to set the performance level to 15 on my laptop results in errors.
nouveau 0000:01:00.0: NVIDIA G96 (096500a1)
nouveau 0000:01:00.0: bios: version 62.94.3c.00.15
nouveau 0000:01:00.0: fb: 512 MiB GDDR3
The kernel module has options: config=NvClkMode=15
That leads to errors:
nouveau 0000:01:00.0: clk: failed to raise voltage: -22
...
nouveau 0000:01:00.0: clk: error setting pstate 3: -22
After that the contents of /sys/kernel/debug/dri/0/pstate are:
03: core 169 MHz shader 338 MHz memory 100 MHz
05: core 275 MHz shader 550 MHz memory 300 MHz
07: core 400 MHz shader 800 MHz memory 300 MHz
0f: core 625 MHz shader 1563 MHz memory 800 MHz AC DC *
AC: core 275 MHz shader 550 MHz memory 799 MHz
Kernel log and VBIOS will follow.</pre>
