Comment # 32
on bug 49981
from Benjamin Lee
On my TURKS chip (HD 6750M) the radeon_pm_print_states() output shows that I
should be using POWER_STATE_TYPE_POWERSAVE instead of POWER_STATE_TYPE_BATTERY.
I don't know if this is true for all TURKS chips or what other chips are
affected, but the following patch against 3.9-rc5 fixes power profiles on my
MacBookPro8,2.
