[Changeable tap counts DoubleTap2Wake]
You can set tap counts of doubletap2wake.
echo [tap_counts - 1] > /sys/android_touch/doubletap2wake
Available values are 0 to 9.
(0 will turn off the doubletap2wake.)
If you set 'echo 2 > /sys/android_touch/doubletap2wake'
Screen will turn on after 3 taps and you will tap 3 times in 300ms(100ms * tap counts).
If you set 'echo 9 > /sys/android_touch/doubletap2wake'
Screen will turn on after 10 taps and you will tap 3 times in 1000ms(100ms * tap counts).
Try it!
In Kernel Adiutor 'Half' is same as 'echo 1 > /sys/android_touch/doubletap2wake'. (Double taps)
And 'Full' is 'echo 2 > /sys/android_touch/doubletap2wake' (Triple taps)
[DoubleTap2Sleep on Status bar]
If you double tap the screen at status bar location(top of the screen), it will turn off the screen.
[Sweep2Sleep on Navigiation bar]
If you swipe the screen at navigation bar location(bottom of the screen), it will turn off the screen.
[Screen Off Volume Control]
== For Volume Control ==
If you sweep touchscreen up or down in SOVC_TIME_GAP (ms) time
and detach your finger, volume will increase/decrease
just one time.
Otherwise if you sweep touchscreen up or down and hold your
finger on touchscreen, volume will increase/decrease
continuously based on SOVC_VOL_REEXEC_DELAY (ms) time.
See the demo video
http://tp.jollaman999.com/jolla-kernel_AIO-bullhead/Screen_Off_Volume_Control.mp4
== For Track Control ==
If you sweep touchscreen right to left in
SOVC_TIME_GAP (ms) time, you can play next track.
Otherwise if you sweep touchscreen left to right,
you can play previous track.
Also if you sweep touchscreen right or left and hold your
finger on touchscreen, track will change
continuously based on SOVC_TRACK_REEXEC_DELAY (ms) time.
SOVC_TIME_GAP 250
SOVC_VOL_REEXEC_DELAY 250
SOVC_TRACK_REEXEC_DELAY 4000
Thanks to @flar2 for prevent to sleep bullhead's touchscreen.
== ARP Project ==
ARP Spoofing Attack Protecting Project. Protect to update MAC address of the gateway.
>> Currently implemented <<
- arp_project: Ignore reply when request not proceeded or source IP is different with requested target IP.
- arp_project: Ignore request when gateway update attempt detected from other hardware address.
== MSM Thermal Tunable options ==
Parameters are here '/sys/module/msm_thermal/parameters'
[msm_thermal Tunable options]
= poll_ms - msm_thermal will check the device's temperature every this milli seconds.
= temp_threshold - Limit the frequency of LITTLE when the temp is reached to this value.
= temp_big_threshold - Limit the frequency of big when the temp is reached to this value.
= temp_big_off_threshold - Turn off the big cores when the temp is reached to this value.
= temp_step_little - If 'temp_step_little = 4' and 'temp_threshold = 60', frequency will decrease like below.
└─temp = 60 --> LITTLE's max frequency will decrease one step.
└─temp = 62 --> LITTLE's max frequency will decrease one step.
└─temp = 63 --> LITTLE's max frequency will decrease one step.
└─temp = 64 --> LITTLE's max frequency will decrease two steps.
└─temp = 65 --> LITTLE's max frequency will decrease two steps.
└─temp = 68 --> LITTLE's max frequency will decrease three steps.
= temp_step_big - If 'temp_step_big = 2' and 'temp_threshold = 60', frequency will decrease like below.
└─temp = 60 --> big's max frequency will decrease one step.
└─temp = 61 --> big's max frequency will decrease one step.
└─temp = 62 --> big's max frequency will decrease two steps.
└─temp = 63 --> big's max frequency will decrease two steps.
└─temp = 64 --> big's max frequency will decrease three steps.
= freq_step_little - Frequency decrease step for little.
= freq_step_big - Frequency decrease step for big.
= temp_count_max_little - If this value is 3, LITTLE's max frequency will decrease 1 to 3 steps.
= temp_count_max_big - If this value is 5, big's max frequency will decrease 1 to 5 steps.

It uses stock cpu-boost and governor. It will up to 1248 while touching.
I'll find a good solution later.
Here is screen shot of mine.

Thanks for uploading! About to try it out now.
Will you consider implementing "double tap to wake" in the future?

---

Just curious what is done to fix the yellow screen? Is that automatic or do I need to change settings?

If you use stock kernel. You will see the yellow screen. This kernel fix that problem. You don't need to change it.
You can use kcal control app if you want to control the calabration.

Nice job adding f2fs support. Thanks for all your hard work

---

Many thanks for this, my phone is affected by a slightly yellow screen, compared to my friend's 5x.
This color calibration pleases my eyes, I haven't compared it with his "perfect" phone yet, so I can't attest to accuracy, but it's certainly pleasant.
Again, thanks.

---

@jollaman999 nice job man and sweet surprise that you have added f2fs and also compiled twrp to support it as well in the download. Kudos my dude

---

wow! f2fs! thanx for your work

---

Does any rom support f2fs? I don't think it can be changed in this version of twrp
