Please call it blu_plug. When I read "bluplug" I thought it said something very different! :laugh:

It is a better implementation of Google's logic that tells your 4 cores when they should be online, and when they should be offline.

Wicked!

Finally pushing out blu_plug: Dynamic hotplug for hammerhead

Lot's and lot's of hours coding and testing, very proud of the outcome.
Special thanks to my testers and apb_axel for making UKM tottaly compatible with blu_plug and Code_Blue.

blu_plug is still WIP, stay tune for more nice stuff in upcoming weeks

Both my cpu governor blu_active and hotplug blu_plug were forked to other devices like Nexus 4 and LG pad and so on.
Damn proud to be BLUE! ANd just the other day, a naive guy called me insecure...

Keep it real, keep it true, keep it #Code_Blue

[size=14]Code_Blue r316[/SIZE]
- blu_plug: Dynamic hotplug driver for hammerhead (enabled by default min 2 core online, max 1 core screenoff) , Driver recode and rework, Tune initial values, Improve suspend/resume routines, down_timer_cnt can't be lower than up__timer_cnt, missing bits, Do not offline a cpu if it's boosted by cpu-boost, Set up_threshold to 70, let's try without jiffies
- blu_active: Since we got blu_plug, let's rename and keep it linear, let's add the file, shall we?
- cpufreq: create a helper function to get CPU utilization. Picked from @stratosk
- Revert "[backport] sched_rt: Upstream fixes"
- Revert "bluactive: let's try and live without the idle notifier and rely on the timer instead."
- zlib: clean up some dead code
- netlink: add signed types
- net/l2tp: don't fall back on UDP [get|set]sockopt
- Tuned some cpufreq tunables, set sched_mc_power_savings to 2
- Use UKM v3.3.1 or higher to control all tunables

Code_Blue r407
All right crew!

Just pushed r407, go get it. Now.

Add the ability of touch boost to blu_plug (now with 1 core min, 2 cores on touch), you can use older setting of 2 always online if you prefer.
Also I tweaked thermal levels to match more conservative values.

CM branch has all the goodies merged now, but I am not happy with dt2w in either branches: I still notice some leakages in some particular situations, will test more during next week. If I am not happy with the results, I am going to remove touchy touch stuff from my kernels.

Some fun facts: r398 just hit the amazing 5,2k hits. Damn

Vom 407 habe ich bis jetzt nichts gutes gehört (Ruckler etc.)

Er und seine Tester,
haben keine lags .............
sagt er;)

Auf dem AH Forum haben viele (alle)
lags.
Wollte es nur mal weiter geben

Über die Qualität dieser "Bugreports" lässt sich auch auch trefflich streiten...
Kein einziger nennt die Rom, sonstige installierte mods und/oder Tweaks (Xposed, UV etc).

Information about the lag with Build 407

The issues with 407 (some of you report lags) are located, a updated build with the lag fix is coming soon, no ETA, It will work as quickly as possible.

Be patient.

All right crew!

input boost bug on blu_plug is fixed. Big shouts to my blue beta posse :highfive:

Both AOSP and CM builds were updated (although the bug in CM didn't show). Never settle for nothing more than perfection.
I also made an improvement on the process, let's see if anybody notices it...

Get involved, test, play, donate, help, contribute.

LOL...

Dafür funktioniert bei Version 412 jetzt der DeepSleep leider nicht mehr, ... ich warte auf eine neue Version, solange kommt wieder die 350 / 376 / 398 drauf.
