Changelog:
02.01.2014:
+ merged mk9 source drop
+ fixed usb connection
+ fixed execution of some init.d scripts
+ changed calculation of next freq in pegasusq (based off a commit by stratosk to ondemand governor, which giot merged into linux 3.11)
+ reverted Sec Oom Killer (maybe causeing some random reboots)
+ switched to latest linaro toolchain (4.8.3 of 12/2013)
26.12.2013:
+ fixed video recording on aosp roms
25.12.2013:
+ cleanly merged update13 (thx to yank555-lu), my previous merge was messed up
+ addded async fsync by htc (ported by faux123)
24.12.2013:
+ merged samsung update13
+ switched back to O2 compiling mode (smaller kernel image, maybe better stability)
+ hardware keys backlight options working for samsung roms as well now
+ re-added oc up to 2 ghz (for those whos device can handle this, mostly added for note2)
+ re-added devil kernel boot logo
+ updated adbd binary to get rid of countless errors in logcat
12.12.2013 part2 :
+ samsung 4.3 roms: added new additional mountpoint for external sdcard ( /extSdCard)
+ aosp 4.4.x roms: export path of external storage, needed by some apis
12.12.2013:
+ merged samsung update for note2 (contains fixes for memory management, mali driver, lowmem killer option SEC_OOM_KILLER, new modem driver, ...)
+ backported cpu boost driver
Code:
When certain bursty and important events take place, it might take a while
for the current cpufreq governor to notice the new load and react to it.
That would result in poor user experience. To alleviate this, the cpu-boost
driver boosts the frequency of a CPU for a short duration to maintain good
user experience while the governor catches up.
Specifically, this commit deals with ensuring that when "important" tasks
migrate from a fast CPU to a slow CPU, the frequency of the slow CPU is
boosted to be at least as high as the fast CPU for a short duration.
Since this driver enforces the boost by hooking into standard cpufreq
ADJUST notifiers, it has several advantages:
- More portable across kernel versions where the cpufreq internals might
have been rewritten.
- Governor agnostic and hence works with multiple governors like
conservative, ondemand, interactive, etc.
- Does not affect the sampling period/logic of existing governors.
- Can have the boost period adjusted independent of governor sampling
period.
+ improve swap per google's suggestion
+ enabled SEC_OOM_KILLER:
Code:
This enables 'Android-Style oom-killer'
The way to select victim by oom-killer provided by
linux kernel is totally different from android policy.
Hence, it makes more sense that we select the oom victim
as android does when LMK is invoked.
+ switched to zswap (backported from linux 3.13) + vnswap instead of zram
03.12.2013:
+ gpu control: voltages are applied as deltas internally (no noticable change for users, this just was needed for the second change below)
+ gpu control: if gpu freq. gets changed by user, only reset its matching voltage, all other voltages stay untouched.
29.11.2013 part 2:
+ fixed apllying of custom gpu voltage
+ removed intellyplug driver (wasn't working properly, consumed much battery, made boot up take longer and it was unstable)
29.11.2013:
+ fixed: secondary rom no longer stuck at max freq.
+ gpu control: automatically set voltages according to changend freq (ported from yank555-lu), you can apply your own voltages after you have changed all freq (changing a freq, causes the voltages to be reset again)
26.11.2013:
+ added sepreate initramfs for cm11 and omni
+ recovery: fixed wiping of secondary filesystem
25.11.2013:
+ added support for omnirom, including dualboot
24.11.2013:
+ partial updated mali driver from SEA update 1 (this also fixes a typo in original implementation)
+ properly applied dualsound engine support, boeffla and scoobidoo (unlike other devs, this implementation only allows one sound mod to be active at a time. if you switch on boeffla (in boeffla app for example), scoobidoo gets disabled automatically. if you turn on scoobydoo in deviltools (new option), boeffla gets disabled automatically)
22.11.2013:
+ fixed hardware keys backlight settings and added more options to Deviltools
+ small fixes to gpu interface, compatible to new Deviltools
+ switched to latest boeffla sound engine
+ small mdnie related corrections
22.11.2013:
+ added gpu control, needs to be set manually for now.
Quote:
- set frequencies (5 steps) :
echo "step0 step1 step2 step3 step4" > /sys/class/misc/gpu_control/gpu_clock_control
- set frequency-step thresholds (up & down)
echo "step0_up% step1_down% step1_up% step2_down% step2_up% step3_down% step3_up% step4_down%" > /sys/class/misc/gpu_control/gpu_clock_control
- set frequency-step voltage (5 steps) :
echo "step0 step1 step2 step3 step4" > /sys/class/misc/gpu_control/gpu_voltage_control
available voltages :
600000 - 1400000
+ ARM: SMP: use a timing out completion for cpu hotplug
+ init.d support for sammy 4.3
+ dualboot support for all supported roms (i couldnt try this. be careful!)
20.11.2013:
+ fixed loosing baseband on aosp roms
+ added support for cm11
+ some code cleanup
+ reverted SEA update 1 (seems to be faster without...)
19.11.2013:
+ merged SEA update 1
+ some small code fixes and cleanups
+ updated wifi driver from note3
+ sammy4.3 initramfs: disabled creation of 300mb zram (yank555-lu)
+ aosp 4.3 initramfs: reverted back to previous ones
16.11.2013:
+ fixed and readded mdnie control
+ fixed kernel version been displayed under "about phone"
24.10.2013
+ backport interacctive governor from googles linux 3.4 kernel source + enabled it
+ updated zzmove cpu governor
+ cpufreq: Save and restore min and max frequencies.
+ cpufreq: Save user policy min/max instead of policy min/max during hotplug
+ cpufreq: Only apply driver limits for scaling_min/max_freq writes
+ linux 3.0.101 (last update)
