Features:
Vibration intensity tweakable
- Allows to change vibration intensity
To change value:
Code:
echo x > /sys/vibrator/pwm_value
Change x with a number between 0 and 60. 0 is the strongest, 60 is the weakest.
Dynamic management of dirty page writeback
- Based on a Christopher83 commit.
- Allows to dynamically manage the dirty page writebacks with two different intervals, one when the screen is on and another when the screen is off.
- By using a higher interval we have better performance and less battery consumption, with a very low risk of data loss.
To enable it:
Code:
echo 1 > /proc/sys/vm/dynamic_dirty_writeback
To disable it:
Code:
echo 0 > /proc/sys/vm/dynamic_dirty_writeback
To customize intervals (in centisecs):
Code:
echo xxxx > /proc/sys/vm/dirty_writeback_active_centisecs
echo xxxx > /proc/sys/vm/dirty_writeback_suspend_centisecs
default for active: 1500
default for suspend: 500
tested values: 3000 - 1000 , 6000 - 2000
