Why would you have to flash one each week? The weekly part just means that its the newest version and that he also will release a newer one in about a week.

No need to keep flashing unless you want the latest and greatest

I found some info over at roozwiki, gave a good simple explenation for most

http://wiki.rootzwiki.com/CPU_Governors

but it still doesn't give much information about some of the others...

Oh well, like pokemon, I shall catch/try them all

[Samsung Galaxy Nexus] jakiej:
some bugs, maybe?

hi r_data, thanks for the great kernel, however i noticed something buggy..

1. it gets really hot when booting, but will cool down afterwards.

(once it just kept rebooting again and again due to the high temp and I had to pull the battery to let it cool down a bit so that it would boot again.)

maybe the built-in default clock-freq is too high (which is not controllable by script during booting)?

2. undervolting is very flaky.

I came from franco, where the settings (SmartReflex disabled) http://i.imgur.com/KHHB5.png

is rock solid. With the latest air (#251), it would reboot my phone even if I added 100mv to each of the entries with otherwise default kernel settings.

However, if I use any static governor (performance, or powersave) I can undervolt specific freq successfully. If I switch between these undervolted freqs (by changing min, max freq, or governor), my phone immediately halts or reboots.

here might be something helpful:

according to http://minooch.com/franciscofranco/Galaxy Nexus/JB/Jelly Bean/appfiles/changelog-n.txt

franco r231 says* "Undervolting should work properly now", which should respond to commits https://github.com/franciscofranco/Tuna_JB_pre1/commits/4.1

around July 27.

I am not a kernel dev, but I hope you could determine if those things helped.

I flashed r231 last week and had no problems but after switching kernels, I tried to flash it again and I got a boot loop. I was using the same file that I had already downloaded last week. I tried to download r251 and the same thing happened. Any ideas as to what's going on?
[Samsung Galaxy Nexus] LNJ:
It's probably a ram disk modification by the other kernel. You may have to re flash rom and flash AIR.
[Samsung Galaxy Nexus] IgnorantNerd:
I have no idea what that is but I'll try it lol. Thanks!
[Samsung Galaxy Nexus] samthe2can:
Got to ask, why is interactive default now? I run PegasusQ underclocked at 230-1060 and it's still smoother than interactive on the standard CPU clocks

Just 2 quick questions.

Does this kernel work together with any of the kernel tools out there (Trinity, Franco or Ezekeel) ?

and

doubt that Trinitys Contrast Interface is supported or did i miss something ?

Have heard nothing but positive things about Air and would like to give it a go. I'm sure this has been answered already and apologize for possibly being redundant, but can I use Franco's app to adjust kernel settings? And does this kernel allow for color control? Thanks in advance for your response.

[Samsung Galaxy Nexus] zyonee:

[Samsung Galaxy Nexus] Riekr:
thanks for this kernel :)

anyway i started testing some of the available governors and i think hotplug is not bad (after interactive, but better battery and better responsiveness than ondemand) but i noticed that when a cpu goes offline, when changing the governor (to interactive for example) the cpu doesn't come back online.

so if anybody is testing governors i think it's better to do a reboot (i was trying to check if wheatley is multi core but it seems not to be)

Hi r_data,

I tried to compile the jb branch from source (for personal use) and I am getting errors:

/home/******/android/toolchain/arm-2011.03/bin/arm-none-eabi-ld: cannot find arch/arm/boot/compressed/piggy.xzkern.o: No such file or directory

I checked the locations and I did notice that at arch/arm/boot/compressed, it only had piggy.xzkern not piggy.xzkern.o. Tried to rename it to "piggy.xzkern.o" but just got another error:

arch/arm/boot/compressed/piggy.xzkern.o: file not recognized: File format not recognized

I don't know how to make heads or tails of the other errors, I'm a noob at compiling kernels so I don't really know where/what went wrong. Is it because I'm using a different toolchain (CodeSourcery)? Can you point me in the right direction? :confused:

This kernel have muck better battery than Trinity and Franco kernel for me.

Excelent battery with about 3~4h screen on. I have 3G always on. With trinity and franco I can only get 2h screen on time.
[Samsung Galaxy Nexus] Doodsz:
How does pegasusq work? :p
[Samsung Galaxy Nexus] samthe2can:
Basically, ondemand with some clever hotplugging...

So It's close to Hotplug, but it will ramp up the CPU on core0 before switching core1 on.

It was built for quad core devices (Galaxy S3), but it has been modded to be dual core friendly.

Honestly, it makes my phone run smoother than anything else without any penalty to my battery.
[Samsung Galaxy Nexus] Riekr:
Pegasusq was running my phone hotter than hotplug which I'm currently using lasting battery for about 2 days of average usage.

Checking on console hotplug seems to scale freq down And decide how many cores to keep online better than pegasusq.

I still have to try latest kernel but I advise to give hotplug a try at least.

To be perfectly honest, I have no idea. I just cloned the jb branch and used air_defconfig in my buildscript. It builds okay with tuna_defconfig.

Or on the other hand just better battery saving?

My observations:

Got 2 freezes within 3 hours yesterday.

There was no last_ksmg.

Phone got hot with pegasusq and sio.

Feeling with this gov was very, very smooth. Battery was very nice too.

Changed back to interactive /bfq. Phone is cooler and no freeze within the last 24h.
[Samsung Galaxy Nexus] Doodsz:
Question. What's the I/O control for?

JellyBeaned from my Nexus S
[Samsung Galaxy Nexus] albatros_1994:
you mean the i/o scheduler?is the scheduler that control the kernel-memory(NAND?no ram,right?) i/o
[Samsung Galaxy Nexus] Riekr:
I/o scheduler is a piece of software inside the kernel that controls how data is phisically written to the disk.

This includes multiple operation aggregation (tagged queueing) and scheduling of the operations in appropriate CPU run queues in order to be more efficient.

To be short since in SD cards or solid state disks there is no seek time and usually write speed is low new schedulers have been created to keep the system smooth (sio, vr and bfq if I'm not wrong).

I've not tested differences from one to another but bfq is very promising and it's now the default for this kernel.

[Samsung Galaxy Nexus] Pepper67:
I am lost with this whole modding thing.

Would this be a good kernel for someone that wont be messing around with the settings? Not looking to over clock or anything like that, just want the good battery life.

What type of color changing can be done? I read people talking about it but not sure which colors they're talking about.

I have cm10 on my phone (first time using a rom), how would it work with this? Should I try another one?

Do I need to wipe my phone when switching between roms and kernels?
[Samsung Galaxy Nexus] Riekr:
You should wipe when changing ROM not kernel.

default settings are ok, you can experiment some different CPU governor in order to achieve some better battery usage and you should be able to select it from cyanogenmod performance settings (warning dragons ahead ;) )

I like default gnex android colors but you may try trickster mod app from xda and take a look to some different color profile (this kernel default is quite similar to the stock one anyway)

Remember that if you install trickster mod you should disable "apply on boot" check box in cm performance settings in order to fully use only trickster mod settings (which are more exhaustive but more complex)

[Samsung Galaxy Nexus] Pepper67:

You should get a kernel controller app. Trinity app works fine with this kernel also u can flash cna rom which i found highly customizable and u will find loads of option on settings for modifying ur kernel.

If you don't want to mod anything but the kernel the settings that comes with this kernel are almost equal to the stock ones.

You can do a nandroid backup , test air kernel an later choose to go back to stock or install something else like trickster mod app which is free and you can find it in this forum

Hi r_data,

first of all, thanks for the work you're doing for our Galaxy Nexus!

I would like to ask you some questions:

1) I'm using the stock JB rom. Do I need to flash something before in order to correctly using your kernel? I mean, the init.d support is still needed? Do I have to flash the GN_Add_init.d.zip?

2) Which are the default color settings of your kernel? Contrast, gamma offset, color multiplier...

Thank you again!
[Samsung Galaxy Nexus] lippol94:
Just to let you know :)

I checked r_data github activities and it seems we're getting a nice rom (AOKP Based) from him :)

I suppose kernel development will start again as he finishes the first rom release.

Cheers!

hey i have tested the pegasusq governor and it doesn't hotplug the second core!
