Galaxy Nexus - Popcorn Kernel v11.4

[domi1711 16]

Popcorn Kernel

Quelle -> https://forum.xda-developers.com/showthread.php?t=1508068]xda-developers.com

Es wurde wieder einiges Verbessert, seht bitte im XDA Thread (link unten) nach für Details. Ich hab ihn mir grad draufgespielt und muss sagen dass mich die Performance mit dem gallimauffry Governor echt überzeugt!

Akku Bericht folgt

edit: es ist Absicht dass die min. CPU Clock bei 700MHz steht! Der Stromverbrauchs Unterschied zw. 300 und 700MHz ist minimal, aber bei 700MHz hat die CPU ihre Arbeit schneller erledigt und kann dann länger schlafen, das spart insgesamt Akku.

Eine sinnvolle Neuerung wäre, wenn es nur mehr 2 oder 3 C States gäbe, also zb, 700MHz, und 1350 MHz, dann würde sich die CPU weniger beim switchen verhaspeln und kann noch effizienter arbeiten. Zusätzlich können (denk ich mir halt) die Kernels etwas schlanker ausfallen dadurch. Bei meinen Computern mach ich das seit Jahren so. Ich werd das den Kernel Köchen mal vorschlagen

Habe unlängst diesen Kernel auf xda-dev entdeckt und ausprobiert.

Er ist in Akkuverbrauch/Leistung echt Spitze! Testet selbst

[B][U]Changelog:[/U][/B]

v11.4


[LIST]

[*]evdev patch to hold less wakelocks

[*]GCC graphite optimizations

[*]Some SIO (Simple IO Scheduler) Optimizations

[/LIST]



v11.1


[LIST]

[*]Patched up to 3.0.34

[*]Reverted RAM Overclock for now

[*]Used the git implementation of SHA - this should give faster boot-up times

[*]Applied PegasusQ patches from gokhanmoral

[*]I went back and changed some of the PegasusQ tunables to run better on our phone

[*]Some other small changes - check the repo

[*]PopcornScript now has the ability to set settings on boot, as well as control cpu and governor settings

[*]To save your boot-up settings, just copy 99sonic from /system/etc/init.d/ to your sdcard. After a flash or system wipe, you can just copy it back to /system/etc/init.d

[*]To stop the settings on boot, just delete everything after "## Kernel Tweaks ##" in 99sonic or just delete the who

[/LIST]



v11


[LIST]

[*]Compiled it with the Linaro Toolchain (GCC 4.7), plus some additional optimizations

[*]Added the PegasusQ governor from Samsung

[*]Changed some AggressiveX tunables, and I am trying a new feature where it changes the sampling rate based on load/speed to give better performance under high load and to stay at lower speeds longer - let me know how this goes

[*]Patched to 3.0.16

[*]Included PopcornScripts

[*]Overrode more mpu trims, to (hopefully) improve overclocking

[*]Overclocked the higher ram speeds slightly

[*]Restored Wifi voltage back to stock, as this may have been causing data drops

[*]Disabled GENTLE_FAIR_SLEEPERS, as this might improve UI responsiveness

[*]Made the Wifi-PM module a boolean

[*]Various patches

[*]Ezekeel's latest SoundControl commit

[/LIST]



v10.3.1


[LIST]

[*]I think I fixed the battery drain - it's fixed for me at least

[*]Touchwake is disabled by default

[*]Applied a bunch of smartreflex/voltage patches

[*]Increased wifi voltage to 1.825V to improve stability

[/LIST]



v10.3


[LIST]

[*]Switched to LZO Compression for faster boot up times (This is why the file is bigger)

[*]Set 192MHz in its own OPP10 Fuse slot to allow for lower voltages

[*]Gave CORE (GPU) its own OPP10 Fuse slot to allow for lower gpu voltages when on lower cpu frequencies

[*]Lowered Retention Voltages for MPU, Core, and IVA

[*]ARM: SMP: use a timing out completion for cpu hotplug

[*]Patched Lowmemorykiller up to Linux 3.4

[*]Added Simple IO Scheduler (SIO) and made default

[*]Used TCP Westwood

[*]tuna-wifi: do not randomize MAC if bootloader doesn't pass it - from Imoseyon

[*]Added TouchWake by Ezekeel, and set it to be on by default

[/LIST]



v10.2


[LIST]

[*]PopcornKernel v10.2 is here! 

[*]Download: https://goo.gl/HjYSg


[*]This was mostly a release focusing on improving battery life and stability.


[*]Changelog:

[*]Updated to IMM76I

[*]The problem with overclocking to 1.42GHz should be fixed

[*]Added a 192MHz slot

[*]Decreased the lowest voltage that smartreflex will go to so it can go lower for the new 192MHz slot

[*]Added the gamma feature from omapzoom

[*]Increased the max temperature, which will decrease latency

[*]Some small tweaks to improve battery life

[*]Some tweaks from Francisco Franco and ch33kybutt to improve battery life

[*]Lots of patches

[*]Some other stuff I probably forgot

[/LIST]



v10.1


[LIST]

[*]Mediascanner wakelocks should be fixed

[*]Reverted using OSWR for the mpu in the C4 state - further research shows that the Google team tried this, but found that it was unstable and could be buggy (meaning it should fix any weird bugs you guys were having while your screen was off.) Also, we don’t have everything for the omap4460 thats needed to fully support the feature.

[*]Separated the aggressive, gallimaufry, and interactive governors into 2 each: aggressive and aggressiveX, gallimaufry and gallimaufryX, and interactive and interactiveX. The ones with an X are the exact same as the ones from before, and the ones without an X don’t have hotplugging.

[*]Added GPU OC Control by Imoseyon - this allows you to, on the fly, change your gpu frequency between 307MHz, 384MHz, 460MHz, and 512MHz. However, I also added a 460MHz slot, and made it so that smartreflex recalibrated the voltage after you change the gpu speed - this is because I am having the 460MHz and 512MHz run on a higher nominal voltage than the 307 and 384 (which run on the same), so users whose phones can’t run the higher frequencies on a lower voltage should be fine. And smartreflex will now lower the voltage if your device can handle it anyways.

[*]Lowered the CPU Transition Latency from 30us to 10us

[*]Doubled the max readahead from 512 to 1024 kbytes

[*]Some select Patches

[*]Some patches for Interactive and InteractiveX to improve speed and battery life

[*]Some things from ch33kybutt:

[*]Lowered the VAUX3 and VUSIM voltages

[*]Tweaked PMIC for longer times in lower power states - but I changed it so that it comes out of the lower power states faster

[*]Some other small stuff I probably forgot

[*]To use GPU OC Control,

[*]go to terminal emulator and type

[/LIST]

Code:

echo 0 > /sys/devices/system/cpu/cpu0/cpufreq/gpu_oc

to change the frequencies, just replace the 0 with anything from 0 to 3

0 = 307MHz

1 = 384MHz

2 = 460MHz

3 = 512MHz



v9


updater script now wipes cache, dalvik cache, and system/lib/modules automatically

Bumped the 920MHz slot up to 1.06GHz - but it remained at the same voltage

Made aggressive even better (“How could this be?!?!” you ask!). Well, I added some code which will make it use the 1.06GHz slot more, which should lead to better screen-on battery life when doing things like web browsing and playing games (but still without lag). The DEF_SAMPLING_DOWN_FACTOR was also increased to 4

Made gallimaufry even better (“How could this be?!?!” you ask again!) - by making it so that it’ll ramp up a bit earlier, giving the user a snappier phone. It also has been tweaked for slightly more battery life.

Fixed the camera not responding issue

Removed Ezekeel’s Deep Idle

Fixed the hotplugging governors (aggressive, gallimaufry, interactive) to not hotplug during earlysuspend registration - this should fix the SOD’s. (thanks imoseyon)

Added PM_FAST/PM_MAX userspace module (Francisco Franco). What this does is you have the option to choose what wifi “mode” you want to use when your screen is off. Normally, the device uses PM_FAST when the screen is on, providing good, speedy wifi performance. But when the screen turns off, it switches to the PM_MAX mode, which slows the wifi down in an effort to save battery. However, this can affect someone streaming music, causing them to have lower quality audio. This patch allows that person to set the wifi mode to PM_FAST when the screen is off, improving their audio quality, but maybe at the cost of their battery life. To set it to enable PM_FAST on screen-off, you can type (in terminal emulator): [/b][b]

Code:

echo 1 > /sys/module/bcmdhd/parameters/wifi_pm

and to disable it echo 0. Or you can just use franco’s app.

Added another patch from franco that powers down the wifi chip when wifi is disabled to save battery

Applied an omap patch: Don’t touch mpu and core state until CPU1 is off

Fix the LOAD_FREQ variable to equal 4.61 like it should, previously it equaled 5.73

Fixed the exponential values in sched.h to use 4.61 instead of 5 seconds

Applied Ezekeel’s latest Color/Sound Control commits

For the full Changelog, visit: https://droidvicious....OPCORNKERNE

v8 LTS

We've spent the last couple of days completely rebasing the source back to 3.0.8 and cleaning out everything that didn't do anything or didn't work - and this has seemed to fix a lot, if not all, of the bugs present in the kernel! Because of this, we also gave it the LTS name. 

Applied security exploit fix from 3.0.18

Updated to latest ColorControl

Re-added Userspace Undervolting - it should work properly now


v7.4.1

7.4 was an internal build

fastcharge patch fixed (it was applied badly)

removed blue tinge since so many people were complaining about it. If you want it back, go to terminal emulator and echo "-8 0 10" > /sys/class/misc/colorcontrol/v1_offset

used xz compression


v7.3

the weirdness in 7.2.1 should be fixed

patched up to 3.0.23

Added Fast Charge by Chad0989 - For more info see here: [Only registered and activated users can see links. ]

md5: 29f116075ccdc22d5a2b4f55ce552622 


v7.2

Removed userspace undervolting to fix the sound issue - the kernel is undervolted enough by default

Enabled C4 State for extra power savings while CPU is idling

Fixed the Init.d and cron scripts not adding properly (If you use SonicTweaks on ViciousMIUI, these are the same scripts as included in the Ultimate Tweak)

Gallimaufry governor tweaked a bit

More tweaks to improve battery life - drod2169

Shortened wakelocks from LTE and Wifi - Imoseyon


v7.1

Updated to 3.0.22

Tweaked Deadline Further (thanks to Francisco Franco)

Used Fast_No_Hz, not jrcu

Added Deep Idle by Ezekeel - (Enable C-states > C1 during hardware-accelerated video playback.)

Added Init.d script, Sysctl.conf, and Cron script to improve speed (make sure you don't already have an init.d script running)

Might have fixed the no sound on undervolt issue - try it and let me know


v7.0.2

Removed GPU Overclock because it drained battery with little to no performance improvement (Ideas also confirmed by Colin Cross)

Backported CRC32 from linux 3.3


v7.0.1

Tweaked Gallimaufry and Aggressive governors for lower latency

Added some fixes to the Gallimaufry and Aggressive governors to reduce the screen unlock lag

Improved IO Latency

Undervolted by default

Tweaked conservative governor again

changed swappiness

upped readahead

Optimized Deadline I/O scheduler - it is now comparable to noop

Battery Life Extender by Ezekeel

Color Hack

Miscellaneous Speed Tweaks

Two versions: One overclocked - 1.35 GHz slot, and 512MHz GPU overclock (this was like morfic's - it's not a true overclock but it does speed up something so we are leaving it in), and one not overclocked

Ich probier das Moped mal aus

[Anthropolis 1.292]

Habe ihn seit gestern am Laufen. Naja, so gut finde ich den Kernel auch nicht. Ist irgendwie nichts ''besonderes''. Die Akkuleifzeit ist bei mir auch nicht gerade prickelnd. Aber mache auch ziemlich viel.

Ich werde ihn jetzt mal Langzeittesten und gucken wie es aussieht.

[flatflo 1.586]

Ich bin bisher ziemlich erfreut über den Kernel!

Da ich das Handy die letzten Tage immer so sporadisch nutze (zwischen den "Lernpausen" ins Forum schauen usw.) und eigentlich jeden Tag fast gleich; ist mir die gute Akkulaufzeit (Governor -> Gallimauffry) sehr positiv aufgefallen. Auch ohne Performanceverlust

Verlgeichbar mit den den frühen Versionen vom franco.Kernel

[domi1711 16]

hab eine Zeit gebraucht, bis ich gecheckt hab warum der Sound ned funzt, aber jetzt gehts

Ich find den Kernel generell ziemlich gut, v.a. weil ich mit dem leankernel überhaupt ned warm werd, der franco in letzter zeit nix gscheits zusammenbringt uuuund, weil dieser popcornkernel noch dazu der allererste Kernel von dem Entwickler is. Das muss man doch unterstützen ^^

Jap, der Akkuverbrauch im idle is genial!

[frico#GER 50]

xda ...[kernel][v7.2][Feb 27][3.0.22][Gallimaufry and Aggressive Governors] PopcornKernel!

[domi1711 16]

7.2.1 Verfügbar! Downloadlink wurde angepasst, aber den threadtitel kann ich nicht ändern :/

[flatflo 1.586]

Habe die Versionsnummer aus dem Threadtitel genommen, so sollte es für die einfacher sein. Am Besten machst du oben ne Überschrift wie "Popcorn Kernel Version XXX" und aktualisierst diese immer

[domi1711 16]

Neue Version 7.3 ist online

1. Post wurde aktualisiert

[flatflo 1.586]

Schon getestet?

Muss mal den neuesten wieder flashen, die Akkulaufzeit war super

[domi1711 16]

seit einer halben Stunde is er drauf, nexus lädt aber noch

Er fühlt sich spritziger an als der CNA 1.6 Kernel (ondemand Governor).

Beim Popcorn Kernel empfehle ich persönlich nach wie vor den Gallimauffry bzw. aggressive governor

Ich berichte wenns Ergebnisse gibt

PS (OT):

bin froh über diese Forum gestolpert zu sein. Macht irsinnigen Spaß die ganze neue SW zu testen Und die Community is auch mehr als nett

[flatflo 1.586]

Das hört man gerne!

Leider ist die Community (auch in anderen Foren) beim Nexus nicht so groß; schade drum!

Ich zieh mit jetzt mal die neueste AOKP Rom + Popcorn...

[domi1711 16]

cool, ich hab noch die B25 von AOKP drauf, ich will mal ein bisschen langfristiger testen ;P

ja, wird schon werden, is ja noch recht neu ^^

hab im ersten Post ein bisschen zu den CPU Settings gefaselt, vielleicht interessierts ja wen.

Hab auch dem Entwickler vom Popcorn Kernel eine Nachricht zu dem thema geschickt, mal schauen was er sagt

lg aus der schönen Steiermark

[flatflo 1.586]

Klar, mich interessiert das defintiv

Mal sehen wie sich die neue Version des Kernels macht! Werde dann morgen mal ein paar Worte dazu verlieren.

[domi1711 16]

Is gut

PS: beim update von Build 25 auf Build 27, muss ich da nur die caches wipen und die neue Version drüberinstallieren? Muss ich die Gapps dann neu flashen?

lg

[flatflo 1.586]

Cache wipen + dalvik cache wipen. Rom installieren und gleich hinterher die neuesten Gapps. Danach Telefon starten, in die Recovery, wiederum cache wipen (mach ich zumindest nochmal) und dann den Kernel flashen.

[domi1711 16]

ok passt!

Kanns sein dass bei den Gapps versionen was nicht stimmt? Ich hab nämlich die vom 24.2 von der AOKP HP, und hier im Thread sind noch die vom 12.2 verlinkt...

[flatflo 1.586]

Ich hab die vom 12.2 genommen. Andere sehe ich gar nicht?! Link?

[domi1711 16]

bittesehr, hier ganz unten bei der Downloadliste

[flatflo 1.586]

Mein Gott, auf der Seite war ich, aber auf die Idee ganz runter zu scrollen bin ich natürlich nicht gekommen -.-

Aber nun wieder zum Popcorn Kernel
