[KERNEL] [Y300/G510] Stock Huawei

[Guest SH3H1]

@moddingg33k

I think your kernal zip file is variety :huh:

If i flash it i can't flash anything until i reboot recovery !

If i use 98Mhz as minimum , when coming from deepsleep phone becomes laggy for sometime (3-5s)

PS. I always wonder why you did put the Synopsis Beta2 down :wacko:

Is it because the lack of wifi driver source?

Just curiosity :D , You now.... ;)

Edit:-

You can't flash anithing because the zip install the new busybox binary

Thanks now i understand :)

EDIT : zram module ( /system/lib/modules/zram.ko ) doesn't exist

It's not build as module, but fully integrated into the kernel just like the touchscreen driver for example ;)

I don't know which APPs you got running and whether you changed any kernel parameter from it's default, neither if you are using SWAP/ZRAM.

 

It's possible, that 98 Mhz is too less for waking up your device and that the governor doesn't scale up quickly enough.

And then how can I create a zram init.d script with 2 zram devices

i never have this problem

[Guest SH3H1]

i never have this problem

I think it's the zram caused problem for me :wacko:

It happens when the zram swap size is full

[Guest luca020400]

I have enabled zram by performance control and i haven't any problem

And then how can I create a zram init.d script with 2 zram devices

 

In general it's recommended to enable 1 zram device per CPU core. But since we got hotplugging and our 2nd core is offline most of the time you won't benefit from having more than 1 device enabled at the same time.

Ok thanks

[Guest]

how?

 

Follow those instructions from Step2 onwards: https://github.com/moddingg33k/android_kernel_huawai_Y300-J1/wiki/README.zram

 

(or use any APP of your choice to do it for you)

@moddingg33k Hi, if i want to port your kernel changing ramdisk, i have to use also your modules on new rom (for example cm11 or other kitkat rom)?

 

edit: i changed ramdisk, repacked boot.img and flashed, when it ends boot animation, phone reboots, i'll try to do an adb log

 

edit 2: i flashed stock kernel to enable adb on cm11 settings, flashed again ramdisk modified kernel and now works  :huh: , that strange, also on kernel version in settings it says "Unavailable"

 

edit3: ok, the problem is wi-fi :), when i enable it, phone reboots, logcat: http://pastebin.com/5P8isaNT,... but there is no trace of wi-fi error at the end

If you want to make it work on KitKat try using chil360's wifi modules (and ramdisk?)

mmm, if i use your wi-fi modules from your ramdisk folder? (ar6000.ko and cfg80211.ko), i'll also try chil360's modules, i am only curious :)

 

edit: chil360's ramdisk works only on slimkat

If you got an working kernel for CM11 you only need to extract it, replace the boot.img (or zImage) and repack it. That might work.

 

If it helps, here is the zImage of this kernel: http://www60.zippyshare.com/v/60074529/file.html

With this way, what wi-fi modules will use? yours or cm11 modules?

 

Edit: used old way: replaced in ramdisk folder all wi-fi modules with yours, seems to work

 

Do you know why kernel version shows "Unavailable"?

No idea, sry

 

Without my ramdisk you might miss the init.d feature and some minor kernel optimizations i made in "init.synopsis.rc"

Can i edit cm11's ramdisk to add your features or they need some other things?

 

And i have to use your lib/modules?

Is this Kernel better than synopsys beta 2?

[Guest Romagnolo1973]

 

 

It would be a long story talking about Huawei and their way to let the modem interact with the linux kernel, but I don't wanna go into too many details. In short: the implementation is not optimal, so it's "normal" that 3G drains battery a lot.

 

 

Yes the implementation made by huawei is terrible, I never saw a smartphone that reach 22 days in 2g as our Y300 (tested by me) and only 2 days in 3g with the same usage (ratio 2g\3g is 10 time ). Others verdors use a worst battery but with a better ratio 2g\3g that is 5 or 8 time

Someone linked a B199 baseband to this forum (can't remember which topic), I flashed it, and it seems to solve my problem. Before flashing I have no signal percentage about 20% in my workplace, but yesterday evening it was 0%. :) I played a vid from youtube to test, about 1%/minute. Before flashing it was 50%/4minutes. So if anyone have huge 3G battery drain, I recommend to flash B199 baseband! :)

But as I tested, I noticed that our GPU is sucking battery too.. I played video from SD card with min brightness, 1%/2minutes. It's quiet big imo.

This looks pretty nice, but nothing for CM10.1 badly :(
But i've read some pages ago you will MAYBE made it also for CM10.1 which would be perfect...

Also few things to make this kernel a bit batteryfriendlier...
- Set the default Swappiness from 60 to 45
- Also you can lower the WiFi voltage

- Add InteractiveX Governor, its basicly same as Interactiv but contains profiels which are good for long batterylife with good performance.

HERE you have a good github from Christopher83, use his kernel in CM10.1 for SGS Plus. Maybe you can pick some good and usefull features ;)

Think with this 3 changes you can get a bit more batteryfriendlier kernel :)

Swappiness is 50

[Guest sgspluss]

Androids default swappiness value is 60 ;)
This means if he doesnt change this value it will be 60 or he change it then it could be 50 or what ever he wants.

He changed this value, with is own script included in the kernel, check for init.synopsis.rc or simply go in /proc/sys/vm/swappiness
