Il Semaphore kernel di Stratosk è sicuramente tra i più usati per il nostro N4 e forse qualcuno di voi lo usava anche per il vecchio Samsung i9000, quindi passiamo subito al dunque.

Change log:
3.1.0 (15/04/2015)
- Merge Android-5.1.0_r0.9 changes
3.0.5 (22/03/2015)
- cpufreq: new per cpu tunable util_threshold (default 25)
- Dynamic hotplug: Change algorithm. If CPUs have different util_threshold, the CPU with the greater one will be chosen
- ondemand: new tunable down_threshold. If load below this threshold lowest frequency will be user.
3.0.2 (18/02/2015)
- Linux kernel 3.4.106
3.0.1 (11/12/2014)
- Merge latest changes from Android source (5.0.1)
3.0.0
- Linux kernel 3.4.105
- Fix initramfs issues (mpdfake, initscripts) due to SELinux. Semaphore init script uses Chainfire's supolicy tool (included in latests SuperSU) to patch sepolicy
3.0.0b (18/11/2014)
- Lollipop release
- Merged latest lollipop branch
- Linux 3.4.104
2.4.0 (19/08/2014)
- Linux kernel 3.4.103
- ondemand: a small fix in check load condition (thanks to moddingg33k)
- tick-sched: Remove unnecessary statistics calculation required by mpdecision (thanks to moddingg33k)
- tick-sched: A couple of fixes from mainline
2.3.3 (19/07/2014)
- Linux kernel 3.4.99
2.3.0 (27/06/2014)
- Linux kernel 3.4.95
- ondemand: Change the calculation of next frequency to utilize lower frequencies more (the governor will be more sensitive to lower loads)
- ondemand: Change default touch load to 65 to keep the touch frequency to 1134MHz (because of the change in calculation)
Please note that you have to change the touch load to 65 in Semaphore Manager until the app update.
2.2.5 (15/06/2014)
- Linux kernel 3.4.93
- ondemand: Be friendly towards latency-sensitive bursty workloads (backport 2 patches that intended for 3.16)
2.2.2 (6/6/2014)
- Merge latest changes from Android KK 4.4.3 kernel source
- Added 2 more tunables to dyn_hotplug to control timer for up and down CPUs: up_timer_cnt (default 2 = 1sec) and down_timer_cnt ( default 10 = 5sec)
- Small improvement to dyn_hotplug
- Introduce a new 405MHz frequency to be used as minimum in case of flickering issues on some devices. This freq uses an HFPLL instead of the PLL_8 (which is used by 384MHz freq) and uses a higher L2 freq. Please note that a little bit more power consumption is expected (but with a small performance increase).
2.1.5 (26/05/2014)

1.8.8 (22/12/2013)
- Linux kernel 3.4.75
- dyn_hotplug: Activate the driver 1min after boot (because during init scripts execution all CPUs should be online to get initial settings. Fixes issue where a CPU governor could be set with default performance governor. Thanks to ihancioglu for reporting and reproducing the issue).

- video: lm3530_bl: Introduce new tunables to control LED driver (LCD backlight)
lm3530_min_br: sets the minimum brightness level (2-114)
lm3530_max_br: sets the maximum brightness level (2-114)
lm3530_br_mode: sets the linear (default 1) or exponential (0) brightness mapping mode.
The sysfs path is /sys/devices/i2c-0/0-0038/
Please note that the exponential brightness mode uses a very low LCD brightness on a low external light. You may need to increase the min_br for better results.
