And for power_dpm_state & power_dpm_force_performance_level: I understand that it cannot be changed when card is turned off (I see that it also disappear from PCI bus space), but I would like to see option to set "initial" dpm state/level which will be used when card is turned om again. This can be usefull for scripts which setting powersave options depending on hostplugging AC adapter. What do you think about using same sysfs entries for it?
That's fine if someone wants to implement it. It's not a high priority for me at the moment.
