Changelog
Code:
2.0.2 (23/01/2014) - Linux kernel 3.4.77 - Reworked double tap to wake functionality

About Double Tap to Wake. Implemented from scratch and hints from show-p1984 and LG G pad kernels (thanks).
The basic idea is known: touchscreen remains _always_ powered to handle input events and wake up the device with a double tap. User have to double tap on the _center_ of the screen (to limit accidentally wake ups). Double tap is disabled by default. To enable it run the command bellow as su:
If you run the above command during screen off, the command will remain pending until the next power on. Then it will be actually executed.
Touchwake functionality is still implemented and it should be disabled if double tap to wake is enabled.
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). - cpufreq: set initial utilization to zero on device CPU addition
1.8.7 (13/12/2013) - Linux kernel 3.4.74 - Gamma control: apply new settings without the need of screen power off/on cycle (thanks to rmcc) - fix sysfs scaling_min_freq file permissions - config: Add CONFIG_NETFILTER_XT_TARGET_TCPMSS support (forgotten upstream update)
1.8.5 (07/12/2013) - Merge upstream changes from KitKat 4.4.1 kernel - Linux kernel 3.4.72
1.8.0 (21/11/2013) - KitKat support - Linux kernel 3.4.70
1.7.6 (04/11/2013) - Linux kernel 3.4.68 - touchwake: Fix issue when disabling driver during screen off and wakelock was active (thanks @ihancioglu for his report) - ondemand: a small cleanup in code (thanks @jugster)
1.7.4 (23/10/2013)
- Linux kernel 3.4.67
- Fix logger loading issue in some custom ROMs
- ondemand: A small optimization in input event (thanks to skkip)
1.7.1 (03/10/2013)
- Linux kernel 3.4.64
- mach-msm: dyn_hotplug: On early suspend use min_online value of 1 (make use of C3 power state on CPU0 when the screen is off)
- mach-msm: dyn_hotplug: Use cpumask_next_zero to find the next offline CPU (thanks to Skkip)
- Possible fix from CAF for a cpuidle bug
- 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.
1.6.5 (17/09/2013)
- Linux kernel 3.4.62
- mach-msm: dyn_hotplug: Schedule driver's work only on CPU0
- mach-msm: dyn_hotplug: Offline the CPU with the lowest current frequency (thanks to Skkip)
- cpufreq: Fixes from Code Aurora
- cpufreq: conservative/interactive: Update the CPU utilization in policy for dynamic hotplug driver (should fix issues with hotplug)
- networking: Include Westwood TCP congestion control algorithm (CuBIC still the default)
1.6.0 (06/09/2013)
- Any Kernel Updater installation method, modified to inject all Semaphore changes on the fly to the current initramfs (thanks to Koush)
- Touchwake changes to avoid conflicts with TouchControl app (thanks to bponury)
- ondemand change to handle input only from touchscreen (CAF)
- Added a tiny service 'mpdfake' in initramfs, coded in C to consume PowerHAL messaged to missing mpdecision (fixes error messages in logcat)
1.5.7 (30/08/2013)
- Revert touchwake changes introduced in 1.5.6
1.5.6 (30/08/2013)
- Linux kernel 3.4.60
- Rework touchwake code for compatibility with TouchControl (thanks @bponury)
- mach-msm: board-mako-display: Use default values for LCD color temperature (should fix stock issue with 'fastboot boot' command. Thanks @mskip for reporting)
- mach-msm: subsystem_restart: Fix CPU detection (should fix issue that the subsystem_restart could not detect the CPU and panic_handler could not restart subsystems properly)
1.5.5 (23/08/2013)
- Linux kernel 3.4.59
- Fix compatibility issues with CM in initramfs
- Fix initramfs files ownership to root

- Linux kernel 3.4.56
- dyn_hotplug: Add max_online tunable to control maximum number of online CPUs
- dyn_hotplug: Add checks when store tunables
- dyn_hotplug: code clean-up
- freezer: Fix deadlock issue (by Colin Cross)
1.5.2 (31/07/2013)
- Linux kernel 3.4.55
- mach-msm: acpuclock-krait: Fix PVS bin information in cputable info
- Add service call in init.rc about SuperSU daemon (recommended by Chainfire)
- Add CM10.2 support for su (untested)
