--- Comment #9 from ArLi Weng <[email protected]> ---
this's i test result:
> radeon.dpm=0, on 3d game 7 fps(v-sync on).
# cat /sys/kernel/debug/dri/0/radeon_pm_info
default engine clock: 200000 kHz
current engine clock: 200000 kHz
default memory clock: 1066000 kHz
> radeon.dpm=-1, on 3d game 60 fps(v-sync on).
#cat /sys/kernel/debug/dri/0/radeon_pm_info
uvd vclk: 0 dclk: 0
power level 0 sclk: 30400 vddc: 949
but with dpm reset infinite, even i boot lts-kernel before 3.14 most time got
fail. i try
with 'radeon.dynclks=0'
with 'radeon.aspm=0'
with 'echo performance > /sys/class/drm/card0/device/power_dpm_state'
all failed. for now, i must work on dpm=0, but that clock is wrong, i don't
known how adjust that.
