Frequently Asked Questions

Q. I tried/want to try this, but I have some doubts....

A. You are reading the right post, find your queries below, if not post it.

Q. Nice work dude, thanks....

A. Well, XDA has done a great job in reducing a man's effort of typing 6 letters to just a click on a button called 'Thanks Button'. Didn't they?

Q. Can I use it in my ROM/MOD ?

A. Sadly,

NO

, sorry. Since the sources have been provided, also kernel may cause problems when flashed after ROM, so its is not recommended to include it in a ROM. But you can obviously refer others to this kernel.

Q. Will this work on GT-S5280?

A. Well, since I don't have that variant, and since its a kernel, I would say not to try this on GT-S5280. And hence, No.

Q. What version of CWM do I need to use?

A. 6.0.2.8 or 6.0.3.7 only, no CWM v5.

Q. I tried this kernel out of excitement, but now realized that it was not for my phone.........?

A. May God Bless You.

Q. What are the features/speciality of the kernel?

A. First, read the 1st post. Second, get/change your spectacles.

Q. Will this work on XYZ Firmware/ROM for GT-S5282?

A. Hell Yeah!!

More Q/A will be added eventually.

If you can't find, post your queries here.

Reserved for kernel tweaks and settings

To get the most out of this kernel, install ThunderZap Control App by [MENTION=4309448]varun.chitre15[/MENTION]

FREE Version - https://play.google.com/store/apps/details?id=com.varun.thunderzapcontrol

PAID Version - https://play.google.com/store/apps/details?id=com.varun.thunderzapcontrolpro

**Note - DO NOT try to mirror this app. If you want to download use Google Play Store only. If you want to share, share the links given above. DO NOT upload the app to any 3rd party hosting site. You have been warned.

In this app, various sections can be accessed by swiping from left edge to right.

CPU Section

Governors - Use smartassV2. You can use ondemand to get the core running at 1400Mhz.

You can adjust max and min frequencies too. Always keep max frequency 1000 Mhz or above.

Memory Management Section

I/O Schedulers - Use any, unless more are added.

Always keep the Dynamic Fsync option on (layout issue there, but blue means on).

You can play with other options too, instructions are mentioned there.

Network

Use any control, I would recommend Westwood. (Layout issue there again).

Don't forget to enable set on boot, can be found in settings.

DoubleTap2Wake

An update to this app should bring double tap to wake toggle under Special Section (And that is why I highly recommend to use this app). But for now -

Install Terminal Emulator - https://play.google.com/store/apps/details?id=jackpal.androidterm

Run the app, and then type -

su
echo 1 > sys/android_touch/doubletap2wake

It can be done using adb shell too.

Run Antutu benchmark, and feel the difference.

Will be updated as per kernel.

Updates

A Q/A thread for this can be found here.

Added AFH mirrors for those who are facing download issues. Next time, AFH mirrors only.

Next Update will bring-

1. CPU Overclock to 1200Mhz

2. Deadline ioscheduler.

3. Full CPU frequency scaling.

Who's waiting?

This is because you were on old stock kernel, this one is based on newer sources.

Use Q/A thread next time. :)
[Samsung Galaxy Star] LehKeda:
Great work i gonna try it , thanks :)

v1.1 Update? Here it comes

Changelog

-1200Mhz Overclock

-Deadline I/O scheduler.

-Improvements in frequency scaling.

-Other optimizations and value corrections.

Removed Odin flashable, since there were no downloads.

Download link updated in OP.

Kernel tweaks (post #3) updated.

Kernel will be soon named Zapdos.

Next Update will be even more big, but its not coming out any soon.

Don't ask about ETA's please.

[MENTION=5822936]AvinabaDalal[/MENTION] : do u compile the source kernel using cm10.1 ?
[Samsung Galaxy Star] corphish:
Nope, I compiled it using ARM toolchain as they had asked to. But I plan to switch to Linaro Toolchain.

And I am not sure whether it will boot CM 10.1 (chances are there though). But it boots perfectly on all stock ROMs.
[Samsung Galaxy Star] cleverior.ipul:
what the different of ARM toolchain and Linaro toolchain ?
[Samsung Galaxy Star] corphish:
v2.0 is up!!

get a kernel control app and reduce clock speed.
[Samsung Galaxy Star] duck'man:
is this kernel have nice battery life in normal frequency than stock kernel sir? :D
[Samsung Galaxy Star] BatDroid:
no.

I/0 - cfq

governor - performance

clockspeed - 1ghz always..

so in normal,it definitely takes up more battery.

[Samsung Galaxy Star] corphish:
Hi all,

I want to make few final releases of ZD Kernel before I discontinue it.

The updates will be mainly kernel version updates.

Currently, kernel updates from 3.0.8 to 3.0.15 are applied. (Patches from kernel.org)

You can find the builds in the link provided from here.

New kernel builds will arrive weekly until the kernel has been updated to 3.0.101.

There is already one build available.

Cheers,

1.6Ghz O.o ?
[Samsung Galaxy Star] corphish:
Woah look who is back!!

And yeah, CPU freq does scale to OC frequency only in ondemand governor though.

CPUFreq driver is seriously messed up in ours and its not easy to get it working like it should.
[Samsung Galaxy Star] psych.half:
I forgot my fb pass and remembered my xda's (°_o).

The device would be toast in seconds if it were actually running at that clock speed.

And only scales in ondemand governor doesnt make sense, maybe the governor is fcked up... Have you tested that the cpu is actually running at OC frequency?
[Samsung Galaxy Star] corphish:
Well, frequency scales in all governors, it shows 1000mhz in all except ondemand, and 1600mhz in ondemand. And cpufreq is so much messed up that its quite difficult to verify OC. I saw its 1600Mhz in cpu-z, so I claimed OC back when I released, but I was and always is learning.

BTW, I love the way internet browsers remember my passwords [emoji14].

Offtopic - Meanwhile we booted CM11 on this little piece of sh**, but sepolicy denials made it impossible to use, and since selinux enabled kernel does not boot in stock, cm10.2, cm11 (it does in cm10.1 o.O), we cannot get avc denial messages in kmsg and can't address those denials.
[Samsung Galaxy Star] psych.half:
Sound like frequency is not being scaled at all.. You can write a noploop c code and get a rough idea of cpu frequency, as this device is single core... or just run a cpu stress testing app like Geek bench 3 and compare the results of ciphers and the likes .. a 600Mhz increase should give you a 15-20Mibs hashes increase

Implementing selinux is troublesome, just disable it in Boardconfig when compiling
[Samsung Galaxy Star] corphish:
Ok, will try geekbench and see. Meanwhile I just saw time in states, it only shows 1000mhz and deep sleep. Ok, if I consider no OC, then why won't the intermediate stock frequencies (600,800mhz) shows up? Highly messed up.

And yeah, we did disable sepolicies in boardconfig, and selinux and related configs in kernel defconfig to boot the build, enabling them (especially selinux in kernel) = non-bootablity.

I even tried sepolicies from open source sprd repos, didn't help either.

About RIL, Samsung Galaxy star pro got unreleased cm with fixed RIL (I played a small role in that too). But in ours, :(

I think its mostly in framework side, nikit could manage to bring up signals and imei by modding framework.
[Samsung Galaxy Star] psych.half:
[MENTION=5822936]corphish[/MENTION] You haven't enabled cpu frequency scaling :|

https://github.com/corphish/zapdos_mint/blob/master/arch/arm/mach-sc8810/cpufreq-sc8810.c

Line 42 :

static int cpufreq_bypass = 1 ;

Set it to 0.

And remove those OC values. you might toast your phone.
[Samsung Galaxy Star] corphish:
[MENTION=5925208]psych.half[/MENTION]

cpufreq_bypass = 0; -> non-bootable, or 'boot-logo' loops, i already tried this long back.

Good thing is, CPU frequency scaling enabled in config fixes app battery uses.

Btw how long are you available?

And I saw you were working on CM11, at github.

I doubt I can be of any help, as I havent been on the bring up process for so long.

And yeah, I just got an old Star Duos from someone. Nice to see that its development has just begun. So a big kudos to you.

I would love to test your CM11, but first I want to build a kernel for stock, that I had failed to give. I know theres Zapdos. and its a great kernel. But I just want to make a kernel for stock, something like that.

Thats why I'm using Zapdos as base. Thanks for your efforts on it and also on this device as whole.
[Samsung Galaxy Star] corphish:
Look who's back..

And I don't get that error. What toolchain are you using? for stock I have always been using the GCC 4.4.3, the one recommended by Samsung.
