K16-6:

- Switched back to TINY_RCU

- Disabled debugging: FRAME_POINTER

- Modified IO tweaks (write flush timing)
[Galaxy S I9000 Android Development] flonec:
hi

speedmod-kernel-k16-6..... CMW

please.. thank!
[Galaxy S I9000 Android Development] jocke_lulle:
Just download neldars sgs kernel flasher from market and use it. It works for .tar files. Very useful app.
[Galaxy S I9000 Android Development] DocMarc73:
Seems a little bit more "stutterish" than 16-5. Are the mentioned tweaks aimed at stability or performance?
[Galaxy S I9000 Android Development] hardcore:
A bit of both. Tiny RCU and less debugging should bring better performance.

The write flush timing thing might fix the black screen problem.
[Galaxy S I9000 Android Development] Denfic:
I flashed the 16-5 kernel ...but my screen seems to be giving some weird stripes rolling down ... when i put semaphore kernel on it i do not have that issue ... is there something to do about it ?? its verry anoying ..!! And is there a bootanimation support in 16-6 ?? (No black screen by the way..just blurring screen) ..!!

JVT wifi bug

Is there a fix yet to the JVT wifi frequent disconnection?
[Galaxy S I9000 Android Development] ZaneZam:
Nope, atm there are just the two workarounds available : 1. setting static ip on the phone or 2. if possible set dhcp lease time to < infinite on the router.
[Galaxy S I9000 Android Development] Jamirobe:
CPU? Phone gets very hot
[Galaxy S I9000 Android Development] jiujitiancai:
I'm on jvs stock rom and flash k16-6,every thing is OK but I fell the touch screen is not sensitive as stock jvs kennel.
[Galaxy S I9000 Android Development] DocMarc73:
Had the same perception, although it think its more some sort of general lack of responsiveness.

I must admit that i switched to semaphore kernel today. Seems a lot smoother again and has a lot of tweaking options.

Sad but true ...
[Galaxy S I9000 Android Development] 6688xp:
I also had used semaphore 1.81. but now i switched back to speedmod. true that semaphore.loks smoother and get a higher scores for benchmarking sw. but at the same time, it eats up a lot of power. which i couldnt bear.
[Galaxy S I9000 Android Development] hardcore:
K16-7:

- Using wifi driver compiled from source

- Added TCP timeout tweaks
[Galaxy S I9000 Android Development] NickDunn:
thanks for the update.
[Galaxy S I9000 Android Development] LupusInvictus:
Ran K16 -6 for about a week, with no black screen issues.

But found it to be a bit laggy at times.

Installed K16-7 and it feels a lot smoother.

Thanks HardCore ;)

Speedmod is still the best for me...
[Galaxy S I9000 Android Development] DocMarc73:
Had never black screen issues with any speedmod kernel (tested ALL except 16 - 7). Stock jvq here. But i clean dalvik cache and cache partition after a couple of krnel upgrades.

Sorry but speedmod got far to slow imo, so i temporarely switched to semaphore. Will come back once performance gets back into focus.
[Galaxy S I9000 Android Development] Jwtiyar:
why JPJV6 not exist???

thanks.
[Galaxy S I9000 Android Development] hardcore:
You can use this kernel on JPJV6, or any other Samsung Gingerbread ROM.
[Galaxy S I9000 Android Development] emelie:
Just flashed K16-7 on JVT. System works as snappy as ever but I can't get into recovery mode.

Only "Galaxy S GT-I9000 Samsung" is showing up but nothing else.

"adb devices" - recognizes the device being in recovery mode.

"adb reboot recovery" - reboots to recovery but still only showing standard text that is shown just before boot animation

Also tried to pull out the battery and enter recovery mode with the 3-button-combo - it enters recovery mode but still doesn't show the menu.

Any clues?
[Galaxy S I9000 Android Development] hardcore:
Recovery mode works fine for me. Maybe try re-flashing the kernel again?
[Galaxy S I9000 Android Development] clonfsp:
I have seen black screen a few times. I suspect it happens when pressing back button repeatedly and fast.

regards
[Galaxy S I9000 Android Development] emelie:
Unfortunately that didn't work. I'm just going to wait for the next release.

It's not that bad, I just wanted to enable logging and check the tweak settings.

But the device is running smoothly so I'm a happy user ;)
[Galaxy S I9000 Android Development] jiujitiancai:
Please hardcore can you look at this?
[Galaxy S I9000 Android Development] umberto1978:
Do you think Hardcore has only Android development?

I guess that he has a real life too, and he does this work only for passion and free.

If you don't like his work CHANGE kernel and don't ask him similar question.

Or may consider that you can make a better one.:)
[Galaxy S I9000 Android Development] DaRkMyk:
Have you tried entering into recovery via the ROM Manager app?

I Swyped this on my Galaxy S
[Galaxy S I9000 Android Development] LupusInvictus:
Hi Hardcore,

Just to let you know.

I had 2 issues in the last days.

1. Random reboots (2x) One while using Chainfire 3D, the other one just random.

2. Black screen - while using WiFi and stock browser and hitting the return button.

Hope it helps makeing the best kernel even better :)
[Galaxy S I9000 Android Development] hardcore:
K16-8:

- Nicer looking kernel version string

- Rebuilt using Linaro GCC 4.6 2011.10

- Ondemand governor patched
[Galaxy S I9000 Android Development] LupusInvictus:
Now that was fast.. :)

Just flashed K16-8

Will report on issues. (will try to repeat the situations K16-7 gave me problems)

Thanks HardCore..
[Galaxy S I9000 Android Development] DocMarc73:
What did you patch? Does it lead to better responsiveness? !-)
[Galaxy S I9000 Android Development] emelie:
I tried via QuickBoot and via adb.

Does ROM Manager provide a different approach than those two?
[Galaxy S I9000 Android Development] teonicci:
I have problems with the new version. If active together bt wifi and mobile networks, one of the three does not work
[Galaxy S I9000 Android Development] hardcore:
If the phone is connected to Wifi, the 3g data will be disconnected.
[Galaxy S I9000 Android Development] teonicci:
is hard to explain ... the phone connects but does not download with wifi .. if I turn off and power back up .. I can download with wifi but I can't call
[Galaxy S I9000 Android Development] NickDunn:
i am using K16-8, and i just convert to ext4 in recovery, i lost alllll my data & apps!!!! is that normal???

please!!!!! :(:confused::o:(
[Galaxy S I9000 Android Development] hardcore:
Not normal. ext4 conversion should work fine without loosing your data. Just tried it on K16-8, no problem for me.
[Galaxy S I9000 Android Development] edy_priyanto:
hi hardcore is there any chance to release kernel for gaming purpose without sacrifice 720 video recording?
[Galaxy S I9000 Android Development] guika:
Xxjvr 16.8 ext4 no problem at all.
[Galaxy S I9000 Android Development] guika:
Xxjvr i tested wifi and chainfire no problem at all.
[Galaxy S I9000 Android Development] LupusInvictus:
No more issues for a week now.

Tried to recreate the reboot/blackscreen situations, but no more problems.

So no clue what triggered it.

Keep up the great work Hardcore.
[Galaxy S I9000 Android Development] derbysig:

no issues found so far. fast and smooth.

thanks hardcore!

K16-9:

- Rebuilt using Linaro GCC 4.4 2011.02

- High resolution timer HRTICK enabled in CFS scheduler

- Some minor tweaks
[Galaxy S I9000 Android Development] cwc289:
High resolution timer HRTICK enabled in CFS scheduler？ More detail plz.
[Galaxy S I9000 Android Development] hardcore:
K16-10:

- Scheduler patched and tweaks adjusted

- Cleanup to kernel configs

This version is much smoother than previous ones. :)
[Galaxy S I9000 Android Development] LupusInvictus:
2 updates in one weekend \o/

Thanks Hardcore for your continued work on the SGS.

ps. Any plans for an ICS kernel ?
[Galaxy S I9000 Android Development] manudevil:
Thank you! I'm trying K16-10. First reboot is very long. After, it seems to be smoother.
[Galaxy S I9000 Android Development] emelie:
Running K16-10 - feels smoother and faster ;)
[Galaxy S I9000 Android Development] emelie:
On another note:

What's your roadmap regarding an update of CWM to a more current version?

Or did you hear from someone who update CWM via ROM Manager after flashing one of your kernel updates?

Was wondering about that because that may prove to be a solution to my CWM problem. And of course my urge to always use the most current version of everything ;)

---------- Post added at 06:22 PM ---------- Previous post was at 05:41 PM ----------

Regarding my recovery mode problem (device enters recovery mode but I'm not able to see that on the display, only through ddms screenshots):

Forgot to flash the gingerbread bootloaders, addicted2088 pointed me to the metaguide and now I'm a happy recovery mode user again!

EDIT:

just mentioning that over here because I thought the kernel was to blame, instead it was my foolishness to neglect the bootloader
[Galaxy S I9000 Android Development] boldeagle:
Slow Quarant, only 987??

Hi

I have installed Speedmod K16-10 and ran the Quadrant Benchmark and got a score of only 987. I am using a stock Samsung ROM, totally original.

I have installed Speedmod before when my SGS was still running 2.2 and I remember getting a Quadrant of 1200+. I was using stock Samsung ROM, not rooted, completely original as well.

What's happening?

Model: GT-i9000

Firmware version: 2.3.3

Baseband version: I9000DXJV9

Kernel version: 2.6.35.7-I9000XXJVT-CL617736 hardcore@speedmod #k16-10

Build number: GINGERBREAD.DXJV9

Any advise will be much appreciated.

thanks
[Galaxy S I9000 Android Development] pikachu01:
Don't believe in Quadrant. Is your SGS smooth? If so, do Quadrant scores matter?

Convert your partition to ext4 to get higher scores, though your performance will be about the same. Conclusion: Quadrant scores are useless.
[Galaxy S I9000 Android Development] boldeagle:
Thanks for your reply.

How do I check if my device has been converted to ext4?

I know when I was on Froyo 2.2, the improvement was tremendous after converting RFS to ext4.

thanks
[Galaxy S I9000 Android Development] powerdams:
K16-10 running great, i notice a performance boost in scolling (between homescreens with spb shell 3D), no micro lag at all.

In my opinion it's the better kernel for JVT for the moment, thanks Hardcore ;)

PS: For the next release it's possible to upgrade the 3D driver to the lastest nexus S one ?
[Galaxy S I9000 Android Development] pikachu01:
I'm not on speedmod but you can go to the recovery and convert to ext4 there.

And the RFS drivers are improved in Gingerbread hence the performance improvement in ext4 is not really noticeable, unless you're using ThunderBolt!
[Galaxy S I9000 Android Development] boldeagle:
Sadly, my SGS is still laggy even with the current Speedmod kernel.

Any suggestions? I am hoping not to have to root or change from the stock ROM as some of my office apps (eg Cisco AnyConnect) require the stock SGS.

cheers
[Galaxy S I9000 Android Development] pikachu01:
Tried ThunderBolt! yet? :)
[Galaxy S I9000 Android Development] boldeagle:
haha I would love to but when I was looking through your Thunderbolt thread, I realize it is a lot more complicated to install vs Speedmod and will most certainly cause some corporate apps to fail.

Oh well, I am hoping hardcore will be able to shed some light on my situation and maybe future versions will help my situation.

cheers
[Galaxy S I9000 Android Development] teonicci:
I have problem with the last version.. if i have bt connected and mobile net connected if i try to connect with wifi, the connection is ok but i can't download data
[Galaxy S I9000 Android Development] kevjcs:
Hi all, i recently using i9000 2.3.5jvt with speedmood K16-9. i m facing wifi disconnect and reconnect in 1min...

any command?
[Galaxy S I9000 Android Development] pikachu01:
If you're not afraid of having to restore from a nandroid, you can try if it works or not for your corporate apps. I have a corporate mail app installed and had no problems running it :)

Remove the "Address Reservation" setting in your router. Also, set the wifi "lease time" to something that is not "Forever" i.e. 2 days.
[Galaxy S I9000 Android Development] burner07:
i always used speedmod back in froyo days... but now i don`t know is it better than semaphore and galaxian?
[Galaxy S I9000 Android Development] ZaneZam:
Hey hardcore, can u plz shed some light in what exactly this version makes it smoother than the previous ones by releasing the source, :) thx!
[Galaxy S I9000 Android Development] powerdams:
In my point of view, speedmod K16 (-10) is more stable than other two, it's not a kernel "catch-all" (= no random reboot !)

If you need a functional phone, it's the best option.
[Galaxy S I9000 Android Development] burner07:
with semaphore i got a reboot every time... even after fresh firmware resoft. but i don`t like i at semaphore because i don`t have voodoo color and sound.. but sound quality is ok
[Galaxy S I9000 Android Development] powerdams:
Agree, the lack of support for the

free version

of Voodoo control and BLN can be a showstopper for some users.

(You probably already know that... with the paid version you can use voodoo control and voodoo sound v10 in every sgs kernel. And you make a good action for supercurio ^^)
[Galaxy S I9000 Android Development] burner07:
so its safe to install paid version of voodoo on this kernel? because it already has some tweaks by supercurio like Improvements to sound quality: 128x oversampling, disable DRC and de-emphasis

- Microphone recording levels using Voodoo Sound "Balanced" preset

BTW i cant install thunderbolt :| why?
[Galaxy S I9000 Android Development] powerdams:
Yes it's safe, you can use voodoo control (the full voodoo driver v10 is included in the paid app)

And for "pokemon 's script", maybe you have forget to root your device in cwm:

In recovery:

- advanced speedmod features

- Root / install superuser

- simple: install busybox+su
[Galaxy S I9000 Android Development] burner07:
i rooted... the problem is i dont get blotscripts on sdcard... why? system and data are mounted
[Galaxy S I9000 Android Development] powerdams:
Honestly i don't know, did you try already to put the thunderbolt files manually with root explorer ?
[Galaxy S I9000 Android Development] burner07:
no ... i never had this problem i think is because cwm...:(
[Galaxy S I9000 Android Development] pikachu01:
Maybe speedmod doesn't mount the /sdcard automatically. Can you also mount your sdcard and see if it works?
[Galaxy S I9000 Android Development] SamHaLeKe:
Hi Hardcore!

Hope to have an update of your amazing SpeedMod kernel with modules from the all new XXJVX (including wifi module) :D

@ Hardcore.

I have been using your kernels since the Froyo versions and they are great. The main thing I miss in the Gingerbread versions are the lower brightness settings. Are you planning to add these sometime?

Hi Hardcore,

Sad to have to report that I had 2 black screen (deep sleep) issues in the last 2 week.

Not sure if it's related but both times Tweetcaster was running in the back ground.

Maybe someone else here can confirm it ...

Still a great Kernel ;)
[Galaxy S I9000 Android Development] thiskar:
root

the root and busybox dosnt work, it never has in my case worked before, cant update superuser and cant install busybox
[Galaxy S I9000 Android Development] clonfsp:
I am developing an application and I am concerned if current speedKernel has something to do with the behaviour of the system.

My app is running a foreground service for an hour more or less. It puts a notification in the tray and start running. It does very little work, only put an alarm for when time is reached the fire another notification and stop the service, and also listen for a few intents. It occupies very little memory (1MB).

My problems come when for some circunstance, when I am not doing nothing with the phone, android kills my service and it takes hours to restart it. To kill the service is normal, but to take so long time to restart it no, as my service is "time based", so when restart it I dont need it. In 'settings/application/services' it appears as restarting for long time.

Can SP kernel do something in this behaviour? Is there any way to tell android to restore application only when passing very little time?

thanks.
[Galaxy S I9000 Android Development] Wossner:
Hi, thank you for speedmod, my first kernel.

One problem, can't root..no su added

Stock jvr
[Galaxy S I9000 Android Development] SamHaLeKe:
Kernel should be pre rooted...

Go to CWM recovery and install root manually (there should be an option in the menus...)

If that fails, flash stock JVZ/JW1 again and then this kernel...
[Galaxy S I9000 Android Development] clonfsp:
I was wrong. After lots of hours of investigation I discovered the problem I was refering was not the kernel. It was about a feature of sdk which is not well documented by google. Sorry. This is a great kernel.
[Galaxy S I9000 Android Development] roundbelly:
can i use the k16-10 with the JVT gb version ? and how to ext4?is app included? sorry noob question
[Galaxy S I9000 Android Development] ZaneZam:
Yes u can use it with JVT as stated in topic ;) and u can convert to ext4 (and do other nice things!) in CWM recovery. To enter CWM recovery u have to use the 3 button combo: turn off the phone then press home+vol up+power at the same time and hold them till phone screen goes on. If the combo worked u will see now a menu in green colored char. If u want to convert system partition to ext4 be sure u have enough free space available in system partition, u could run into troubles if there is too less space free. I suggest to move the ringtones from /system/media/audio/ringtones to sdcard/media/audio/ringtones but to be able to move things out of system u have to root your phone first (also from CWM) and install a app like root explorer, then the conversion should work without troubles.
[Galaxy S I9000 Android Development] Wossner:
So I ve to flash stock jvz, because I ve already tried manual root on cwm and it fails.. No other options?

More: if I convert to ext4 i'm gonna lose data? it's worth doing it?

[Galaxy S I9000 Android Development] Elad92:
Hey, I'm using Captivate and I wonder if you will port this kernel to captivate too, because I was using this kernel when I had froyo, and I liked it a lot!!

Thanks
[Galaxy S I9000 Android Development] ZaneZam:
How exactly does it fail to install root, any error messages? If nothing wired happens during conversion to ext4 you will not loose data but its allways good to have a backup. ;)
[Galaxy S I9000 Android Development] Vogie:
Dose it work for "XWJVZ" ?

Editet: I flashed and working.
[Galaxy S I9000 Android Development] Wossner:
No error mex, simply I select root on cwm then reboot but cant find any su..

Ext4 will make faster gingerbread?

ty
[Galaxy S I9000 Android Development] ZaneZam:
hmm, so you don't have superuser app installed and you can not execute "su" command on console for example with connectbot? Maybe you have too less space left on System partition to install su binary? You could try to flash cf-root kernel before flashing speedmod kernel. cf-root removes the bootup/shutdown sounds from system to free up some space to be able to install stuff in system, details here: http://xdaforums.com/showthread.php?t=788108

rfs is getting better but yeah i think ext4 is faster at least with some tuning, for example the speedmod tuning ;)

hope it helps somehow!
[Galaxy S I9000 Android Development] Wossner:
Mmh good idea.. I ll try it. Just flash cf root with odin? And than flash still speedmod?

In any case I think the problem is my stock jvr, even if I remember it was one of the smaller rom (in MB).. I mean.. For system left space... Wrong tought?
[Galaxy S I9000 Android Development] ZaneZam:
As you have not much options without root installed on your rom you

will have to flash with odin, yep ;) and that's in any case the saver way!

Well, i don't know where you got your stock JVR rom but all the roms that i used in the past (all from samfirmware) had a system size of about 285mb +- 1mb and there was allways enough free space to install at least "su" and superuser app. But i must honestly say that i stopped using speedmod a while ago so i can't say if there are problems with newer roms and speedmod superuser installation.

"And than flash still speedmod?" As i mentioned i don't use speedmod anymore. I used it a long time and loved it! It's a great kernel but i needed some more functionality and that led me to Semaphore. Ok, i don't wanna woo people from here but maybe you can give it a try :) www.semaphore.gr

This kernel is based on cf-root so there is no need to install superuser after flashing

as it will be done automaticly on first boot.

good luck!
