Usage of some features
Dynamic management of dirty page writeback
What is does?
- 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.
Thanks to Christopher83 and kingBABAsula.
Usage-
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

One kernel to rule them all, gg.

i suggest to make a bootmenu like turbokernel on xperia 2011 devices, it's including :
boot to system
boot to cwm
boot to twrp
boot to philz
iinstead of pressing volume button.

@Abhinav2 Pressing vol up in v2 goes into normal cwm touch,not PhliZ.

---

v3 released. You can notice improvements in speed in this version
Cheers,
AJ

com.android.phone has stopped on v3
v2 works fine

First off, a big thank you for your amazing work, yet again.
Downloaded and flashed v3 and the recoveries work great. But as the ROM boots phone FCs along with other things. I did clear cache and dalvik after flashing.
The dual recoveries are indeed a great feature. I'd also like to request that you add Performance Control kernel features because they are really great.
Secondly, when the phone boots the LEDs light up as red, yellow and green. It would be great if you could change it to all blue, because it looks decent that way in my opinion.
Thanks a million again for your great work.

No problem for me, no strange FCs. Phone works good.
EDIT: YAY, finally the high frequencies bug is finally solved in short, system was using high frequencies even when not much power was needed
