Well,I just flashed 11-05 version and I manage to boot the phone, but not without issues :/

Now I will wait for a bit and then I'll try to get into recovery,but I'm afraid to do that! :D

Anyway, even with the .nobootlogo file into my sdcard,just after the kernel flash,the phone was not able to boot: I had to reboot 4-5 times and then,magically,the phone booted :)

Ps. When you talk about "old bootloader"..what is that? And how can I update that? Thanks! :)

Edit: before flashing kernel,I used KernelWipe script.. I don't know if this helps :)

Edit 2: everything is working fine now! the kernel is very smooth on Sentinel Rom and i can get into recovery! :D

Thanks Gustavo!

0511 Nightly : THE BEAST

Hi all,

0511 as of 0507 Is really the greatest Kernel for S2.

BFQ Scheduler behaves fine ;)

The only thing I could notice is that GPU Steps don't go above 267MHz.

Not an issue for me as I don't play games. But for those who do, I think they could have the use of GPU OC abilities.

Hi can install this kernel on ,slim bean and carbon rom?

SLIM BEAN - BUILD 5

[Galaxy S II Android Development] Gustavo_s:
good to know, maybe its a conflict with another kernel configurations
[Galaxy S II Android Development] ammarsg:
thx for great job as i see 11.5 is the best till now sooo i like to try it now on last rootbox but want to ask ,flash it normal or should do wipe kernal or any thing befor .i am on stock kernal now thx again:good:
[Galaxy S II Android Development] :
Hi, you can flash it over Stock RB Kernel.

But you can apply KernelWipe script before if you want, it doesn't hurt.

This is a great kernel as you'll see.

I'm runing latest 'unofficial' RB nightly 12-05 by Kroz and latest Siyah v6 11-05 and they are fully compatbile I confirm.

Except that you may not find Stweaks. It seems RB related issue.(with latest nightly)

You just have to install it with Play Store and you'll be fine.

Enjoy!
[Galaxy S II Android Development] ammarsg:
thx for replay i will try it now
[Galaxy S II Android Development] ruicc:
Hi, Gustavo

Glad to see you back.

Just to report, i've installed latest kernel version (0511) on Carbon Rom latest nightly, and it went well, no stuck on boot logo.

Now, i'm gonna test it, i'll try to give you more precise feedback.

As related by spreadtux i didn't found Stweaks, so i have to download it from Playstore

Thanks for your work, mate, go on.
[Galaxy S II Android Development] :
STweaks seems ROM related as stated in my previous post, not Kernel related.

The proof is that with previous RootBox Nighlty 0507, and same latest Siyah 0511, I had STweaks.

When upgrading RootBox to 0512 and 0513 and flashing Siyah V6, I lost STweaks. QED ;)

Except that, everything is running fine. BFQ behaves fine as far as I can see. (I didn't benchmark it as others did : http://xdaforums.com/showpost.php?p=10669818&postcount=591)

Even It BFQ seems outperformed by VR in this benchmark, I'd better trust BFQ as it seems more trusted in Linux world : https://wiki.archlinux.org/index.php/Linux-ck

And to confirm this, no sign of VR Scheduler under linux ;)
[Galaxy S II Android Development] killar_aka_arabu:
hi gustavo, you have doed good work, thanks very much, but i have a sugest, if you can, ad please posibility to save profiles in stweaks (like gaming, power save or standart)

have a nice day)
[Galaxy S II Android Development] :
Hi,

I don't think it will be possible as STweak is a tool developped by Gokhanmoral not Gustavo : http://www.gokhanmoral.com/

But you can use another tool as CPU Adjuster (see my Sig for Link) to set different profiles.

For gaming profile it doesn't exist in CPU Adjuster nor in others CPU tools like SETCPU AFAIK.

Hope It helped.
[Galaxy S II Android Development] :
0513 in the wild!

I've just downloaded and flashed 0513.

I'm excited to see how CFLAG -O2 will improve the kernel :silly:

Thx Gustavo for that and for Boostpulse & 400MHz GPU Step. Gamers out there should be happy now ;)

I tried to wipe the cache and Dalvik but CWM don't see nothing, only the soft buttons and not other.

How I can solve it? reflash pda with odin?
[Galaxy S II Android Development] mr_zuff:
I had the same problem.. try to do like this:

Flash another kernel from Odin

Boot the rom and open a file manager

Go to your internal sd card and add a new file:call it ".nobootlogo"

Save the file and reboot the phone in cwm

Now try to flash this kernel ;)
[Galaxy S II Android Development] :
Hi I've got the same Phone i9100P and I did not face your problem.

May I suggest you to download the Kernel again. May be there is a problem of integrity with the one you downloaded.

And we could suggest Gustavo to provide md5sum with every release so we could all check if the integrity of what we download is OK before flashing.

CHEERS
[Galaxy S II Android Development] Diechel:
For me boostpulse stays enabled after disabling it in stweaks

Do more people have the same problem

[Galaxy S II Android Development] Gustavo_s:
reboot
[Galaxy S II Android Development] GNUDroid:
following very inerested the topic. i highly appreachiate, that this kernel is continued. of course some people did fantastic work, but real genius let others space to continue and contribute to their work. - ask LINUS for example, who is not every time amused what the andoid and arm community does with his mainline kernel. e.g he complained about too less sharing back to the real linux development. but he respects it and shares his work with all.

so all should be happy that we got an ecosystem of different approaches. choice is very important. and from technical point of view, i see avery good working alternative to other kernels!

send from my 6810. supported by 9100 and my linux desktops. brain in the head and GNU in the heart. community and sharing are freedom are open source. don't be ignorant.
[Galaxy S II Android Development] Diechel:

Did kernel cleaning then flashed again

Still not working. It's not a big problem for me and maybe it's only me

Thanks for your work

Paranoid needs

Hi Gustavo,

I was wondering if I there could be a way to reproduce my paranoid settings I'm using on my linux boxes.

All my ArchLinux setups are encrypted this way :

cryptsetup --cipher aes-xts-plain64 --key-size 512 --hash whirlpool --iter-time 10000 --use-random --verify-passphrase luksFormat <device>

What I need for that would be :

First - Kernel support for AES-XTS 512bits key size, and Whirlpool Hash

Second - Ask Bajee if he could cook the "Encrypt Phone" (https://support.google.com/android/bin/answer.py?hl=en&answer=1663755) fonction into RootBox using Cypher and Hash above.

For the first point, with your kernel, I can't find /proc/crypto :eek: does it mean your kernel doesn't support Cyphers and Hash algorythm? :confused:

Anyway could you think about adding those 2 Major features (xts-aes-512 & whirlpool) into your kernel if possible PLZ.

Once availaible I'll try to convince Bajee to work on point 2.

CHEERS.
[Galaxy S II Android Development] Gustavo_s:
This one?

https://github.com/KiWiX-s2/KiWiX-s2/commit/66c37d65e47af830a7bce96256fc2b9f73e29f62
[Galaxy S II Android Development] :
Hi,

I looked hard for aes xts source code believe me.

it seems it can be found in openssl-FIPS module : http://git.openssl.org/gitweb/?p=openssl.git;a=blob;f=crypto/aes/asm/aes-s390x.pl;h=687bdd94992a04274ce0969218b9ea24c8134903;hb=4f6c4c1896f1fea63053468bfc599d3cf7da93f5

And for Whirlpool Hash fonction it's included in openssl libs : http://git.openssl.org/gitweb/?p=openssl.git;a=tree;f=crypto/whrlpool;hb=4f6c4c1896f1fea63053468bfc599d3cf7da93f5

I don't know if it will be possible for you to merge those codes because I don't know if it's Android compliant.

But I hope it can help you figure how to implement aes-xts and whirlpool

For aes-xts, there will be some changes needed. because max Keysize length is 256 by default and I would like this limitation increased to 512. If easily feasible of course.

Just a quick feedback to gustavo_s, who doing a really gr8 job.

First thanks for being here again and I hope people learned from the closing.

Secondly I'm really happy with the last releases (latest smaller problems in latest release before thread closing).

Also the stweaks settings keeps alive when u set them once, but here I also have a small manco:

It would be cool that it's also there, when u flash a newer version.

Maybe u have once time to check if it's possible and for now a big thanks again.

CHEERS ;)

[Galaxy S II Android Development] deepongi:
well.. decided to try this kernel again... got stuck at boot first. used GS2_KernelWipe script to clear CM/Siyah, flashed again the kernel, and its working fine.

i asked Gustavo_S for permission to post his STweaks settings in CWM format, :cowboy: so all you have to do is flash after the first boot and after entering STweaks app, reboot, enter recovery, and flash one of the two settings:

Gustavo_S_Stweaks_CWM.zip

infected_Stweaks_CWM.zip

my settings are the most friendly possible to optimize the use of the battery. Gustavo_S settings are the ones in the first post.

use what settings you want, of course.

regards,

PS: if the screen is too dark for you, raise the "gamma" value, and leave brightness in "Auto" on the phone settings.
[Galaxy S II Android Development] Gustavo_s:
im not angry :) feel free to post and give feedback, i was in class earlier and couldn't reply your pm

if i change a single letter in customconfig.xml which generates stweaks' UI the settings get reseted to default when flashed, i will try to implement a basic backup/restore option for settings, that is a must have
[Galaxy S II Android Development] deepongi:
i'm glad you’re not angry at me .. :)

and i agree. backup/restore is a must have. is always useful when exchanging rom/kernel... there must be a way to do a backup of /data/.siyah/*, and then do a restore.
[Galaxy S II Android Development] grafenberg:
A little confused about the wifi_pm explanation on tweaks tab... :what:

In my case, a reboot doesn't reset it. It stays on my last choice. So cmiiw, the power saving feature is on if we choose "off (default)"?

Thanks...
[Galaxy S II Android Development] Gustavo_s:
new version keeps settings after reboot and has a better description:

https://github.com/gustavoss/initramfs3/commit/22fd65248e12f6b99f25d2a64f08634b6aecdf93

also added a backup/restore tab, tap backup and your settings will be saved/restored after flashing a new version

I recovered everything, but never managed to get this kernel working. 9/10 boots it will still hang on the loading screen, plus sometimes additionally the screen goes progressively dimmer when it's stuck...

Same ratio trying to get into Recovery - hold Vol down + Home + Power... and oftentimes it goes into Download mode :eek:

[Galaxy S II Android Development] Muchoaliento:
I never mentioned that I have Gustavo's kernel working BTW...as a matter of fact, I had the same problems as you. I just pointed out the steps I took in order to recover my phone, now I am on stock CM kernel.

I may try again with Gustavo's kernel but this time using kernel wiping scripts posted by someone before. Will keep you posted.

guys.. youre doing something wrong... i'm using build 15/05 without any issues and working great !! :cowboy:
[Galaxy S II Android Development] OrangePL:
Boot into recovery... run kernel cleanup scripts, flash, reboot... Where can we possibly go wrong?

The kernel needs work, that's all... It's obviously not safe on every S2 hardware.
[Galaxy S II Android Development] deepongi:
maybe your stweaks settings, no? what kernel cleaning script are you using?

and

AFAIK, the "hardware" its always the same.... maybe your S2 is a quad core or something, with 2Gb of RAM, 64Gb of storage, and a 24MP cam? :rolleyes:
[Galaxy S II Android Development] :
BFQ not needed???

Hi Gustavo,

As seen on Dorimanx Thread about 9.17 release :

"Removed BFQ I/O gov, it's not supported any more, after merges with 3.10.y source. (it's was made for spinning disks, and we have SSD, so it's was waste of RAM)"

I did found few evidences that BFQ performs very well on hard drives but is not optimized for SSD, where NOOP or deadline seem to suit much better.

I previously asked you to add BFQ scheduler because I had my Linux Boxes in mind (with BFQ scheduler).

But I forgot that they use Hard Drives, not SSD.

And our smartphones are some kind of SSDs.

Sorry for the extra work I gave you, but It seems you can finaly remove BFQ in your next release...
[Galaxy S II Android Development] Diechel:
Thanks boostpulse disabled the right way :P :good:

---------- Post added at 11:44 PM ---------- Previous post was at 11:42 PM ----------

http://algo.ing.unimo.it/people/paolo/disk_sched/

"High throughput

BFQ achieves up to 30% higher throughput than CFQ on hard disks with most parallel workloads, and about the same throughput with the rest of the workloads we have considered. BFQ achieves the same throughput as CFQ, NOOP, DEADLINE and SIO on SSDs."
[Galaxy S II Android Development] :
Hi, I saw this article, but if you look at the first part :

It seems that BFQ is really NOT suited for our needs ;)
[Galaxy S II Android Development] OrangePL:
GS2KernelWipe of course.

And by different hardware I meant the chip build. E.g. some people manage to achieve certain UV values, why others report their phone just crashes at the same conditions/ROM. Read about it, then roll your eyes in the mirror.
[Galaxy S II Android Development] deepongi:
ohh ok then... thought your s2 was a quantum computer ... :cowboy:

nevertheless... its working fine for me, soooooo.... :rolleyes:
[Galaxy S II Android Development] grafenberg:
what do you mean? i use this kernel & rootbox nightly all the time...
[Galaxy S II Android Development] Diechel:
True story, so Gustavo can delete it from kernel ?
[Galaxy S II Android Development] :
I'm not sure yet. Because I saw this :

Then latency issues where sorted out with BFQ V6 and addition of EQM Mechanism.

And looking at the commit related to BFQ in Siyah v6 : https://github.com/gustavoss/siyah/commit/2c2a895b077f227e4cfc71da9f51d7427d3d1019

It seems we have BFQ-v6r1 shipped with EQM :

So for now I suggest giving BFQ a chance as it finally seems able to compete with ROW or VR : fingers-crossed:

I'll try to make some I/O Benchmarks between CFQ, BFQ, NOOP, DEADLINE, ROW and VR.

For the latency, it won't be easy to measure because Interactivity and responsiveness are mainly subjective.

Of course Gustavo, the final decision regarding BFQ future is yours ;)

Hey all.

Im wondering if this kernel cant work On sentinel rom v4.50

I tried installing and using the kernel On 3 dif ways.

1.normaly flashing it and start rom.

2. Use kernel wipe script. Instal this kernel and start rom.

3. Use rom and kernel wipe script. Instal the Rom fresh. Then installed kernel. Boot rom.

(ofcourse I tried the wipe cache /dalvik etc.)

I can boot the Rom (in whatever way I installed it) maybe 1 out of 10 times.

The rest of the time my fone Will bootloop or hang at bootscreen and gets very very Hot. There is also no way to get back in recovery Then.

As I said around 1 out of 10 times im Lucky to boot the Rom.

I also tried some other settings /governers /scheduler etc.

But no luck.

Maybe 1 of you have a answer for me?

Cause I always used siyah and would really like to still use it!
[Galaxy S II Android Development] genyagilin:
