Any comments on the performance of T13 on 2.3.3/2.3.4?
[Galaxy S I9000 Android Development] cyberspaceguy:
when I installed this kernel via Odin I have to convert ext4 on recovery mode? thanks
[Galaxy S I9000 Android Development] hardcore:
You have to boot into CWM to install root. This kernel does not install it automatically.
[Galaxy S I9000 Android Development] cyberspaceguy:
I converted filesystems to EXT4 and in recovery mode there is an other step "convert SYSTEM filesystem" is a good thing to do"? ;-P
[Galaxy S I9000 Android Development] sKweezr:
Yes, do the system conversion as well. Otherwise it stays at rfs.
[Galaxy S I9000 Android Development] DocMarc73:
I would't recommend ext4 on system cos it's useless! System is read only, so ext4 wouldn't have any advantages over rfs, but more cpu overhead. Do some reading.
[Galaxy S I9000 Android Development] Perka:
Maybe you can explain or link us?
[Galaxy S I9000 Android Development] cyberspaceguy:
ok thanks for your suggestion!! I will not do it! ;)
[Galaxy S I9000 Android Development] DocMarc73:
Simplified: Ext4 increases write speed but uses more cpu power (battery) while rfs is a bit slower in writing data. The system partition is by default just read-only. So in everyday usage nothing gets written on system partition. Hence reading speed is the same (ext4-rfs), there's no advantage in changing filesystem.
[Galaxy S I9000 Android Development] xchasa:
I've tested rfs and ext4 on filesystems and ext4 is much better for me. Noticeable lag opening apps or going back to home on rfs.
[Galaxy S I9000 Android Development] manudevil:
Thanks Hardcore for the JVS version ! You're the best !
[Galaxy S I9000 Android Development] hardcore:
I found that may not necessarily be true. Nowadays I find that switching /system to ext4 actually improves my battery life! Not sure why, but could be something to do with the way the rfs journaling works.
[Galaxy S I9000 Android Development] Mull1s:
Does the newest SpeedMod (T13) work with an older firmware like JVH?
[Galaxy S I9000 Android Development] hardcore:
Yes it should.
[Galaxy S I9000 Android Development] elhennig:
I found that Antutu Benchmarks gives a slightly higher score than with Voodoo or DarkCore (2900 instead of 2800)

Now I am in the middle of every day use benchmark ;-)
[Galaxy S I9000 Android Development] fcck:
Donated some $ to you hardcore! Keep up the good work!
[Galaxy S I9000 Android Development] LupusInvictus:
Yeb can confirm this.

T13 runs smooth as butter with JVH.

Been running it for a day now and no probs what so ever.

Too early to report on batt. life.

Again a great kernel, thanks Hardcore.
[Galaxy S I9000 Android Development] Mr Majestyk:
Can I just confirm that with this kernel, I don't install voodoo control as the fixes are incorporated into the ROM? I miss having the control over sound properties mainly headphone levels.

I assume T13 will work with JVR. The ROM I'm on is using T10.
[Galaxy S I9000 Android Development] daut:
same here..

ext4 is better for me.

beside that lag, I found that loading much longer with RFS when I open picture using QuickPic..
[Galaxy S I9000 Android Development] flo2lacanau:
It works fine on JVS

JVS odex + K15I-T13 = works fine, no bug detected.
[Galaxy S I9000 Android Development] clonfsp:
I dont know you, but from when I installed T12 I have having problems with calls. It interrups after a seconds of conversation. I can hear others but they can't hear me. I didn't have this problems with T10. I suppose is T13 would be the same.

I have Continuum 6.1 ROM (2.3.4 based)

Does anyone here have the same problem as me?

---------- Post added at 05:53 PM ---------- Previous post was at 05:50 PM ----------

The speedmod kernel looks like does not log any information in log file. Possible hardcode has dissabled it in order to save cpu time and battery. When I run aLogCat I dont see any log register.

Does anybody knows how can I (temporaly) enable it? I need to send a log file to a programmer to help him to fix a bug in his app.

thx
[Galaxy S I9000 Android Development] s3xkiller:
@clonfsp

I think maybe you are using call recording app.

Please try to disable the call recording option and try calling someone to see if the other can hear you.
[Galaxy S I9000 Android Development] clonfsp:
thx but I dont have any call recording app.
[Galaxy S I9000 Android Development] DocMarc73:
I remember hardcore diabled logcat. But i think you can reenable it in cwm.
[Galaxy S I9000 Android Development] clonfsp:
what does cwm mean?
[Galaxy S I9000 Android Development] extralife:
You can't.

Android logging yes, through recovery - but no logcat.

[Galaxy S I9000 Android Development] extralife:
ClockworkMod or the recovery menu

[Galaxy S I9000 Android Development] DocMarc73:
Of course you are right. My fault.

To get into recovery turn phone off. When its comletely shut down, press and hold vol. Up+home+power on.

Looks like on my sgs wifi won't get IP

In my Wifi settings it keeps saying gettin IP from [routername] but after that nothing happens. I have the international version of the SGS.. and flashed the latest which says wifi fix "should" be fixed

I'm on JVS
[Galaxy S I9000 Android Development] stef_ladefense:
tested with new JVT ?
[Galaxy S I9000 Android Development] Tumbling Dice:
No problem 'til now...

JVT successfully rooted with Speedmod in CWM
[Galaxy S I9000 Android Development] ChmT:
I'm on DarkCore kernel with lagfix enabled.

I would like to try Speedmod K15I-T13. Do I need to disable lagfix on DarkCore to flash this?

With DarkCore kernels it's important to have lagfix enabled before flashing it trough CWM or you get bootloop.
[Galaxy S I9000 Android Development] elhennig:
No, no need to disable ext4. I switched between DarkCore 4, Speedmod K15i T13 and Voodoo JVS forth and back without any additional changes...
[Galaxy S I9000 Android Development] stef_ladefense:
not work perfectly !

with easy reboot, dont find busybox

busybox don't have root right for update ...

su update to 3.0
[Galaxy S I9000 Android Development] Asterix040:
My wifi aslo have problems with getting IP. Every other time it won't connect to my routher.
[Galaxy S I9000 Android Development] biscuit26:
is this kernel working with stock bell galaxy s (gt-i9000m) ??
[Galaxy S I9000 Android Development] Silfar:
Same issue here.

BTW: any idea how to root the phone after applying stock and then K15I-T13?
[Galaxy S I9000 Android Development] nmcc89:
Go into cwm>advanced speedmod options and the option to root should be there
[Galaxy S I9000 Android Development] Silfar:
No CWM was installed :(
[Galaxy S I9000 Android Development] nmcc89:
You've tried to get into cwm using volume up--home--power? And you definitely installed the kernel, what does it say in "about phone"?
[Galaxy S I9000 Android Development] Silfar:
Silly me.

Under Advanced Clockworkmod I have 3 options

Reboot recovery

Wipe Dalvik Cache

Wipe Battery Status

Not used to this kind of rooting, therefore I'm unsure (well, wipe battery it isn't of course)
[Galaxy S I9000 Android Development] nmcc89:
No from the main menu you need to go into "advanced speedmod", you'll see it there
[Galaxy S I9000 Android Development] Silfar:
Ah there under ROOT / Superuser

Alright: I got

"Simple", "Adv." or "Ext"
[Galaxy S I9000 Android Development] nmcc89:
just choose simple
[Galaxy S I9000 Android Development] Silfar:
Done. According to Titanium Backup still no root.
[Galaxy S I9000 Android Development] qwan1101:
-->been using "K15I-T10:" for a while now.....

-->upgrading to "K15I-T13" hope nothing bad happen.....
[Galaxy S I9000 Android Development] joopbloack:
how do i install this via CWM? it used to be there is a zip and i can install it easily via CWM. now it's TAR, anyway i can install not by odin?
[Galaxy S I9000 Android Development] Silfar:
I think I know why it won't work. Superuser cannot update, it's giving me error messages. Also when using Midnight or any other Kernel build.

I'd put it on the least Samsung Official 2.3.5. Gonna try with 2.3.4 instead.
[Galaxy S I9000 Android Development] nmcc89:
hm I rooted JVT with midnight 0.7.6. you might not have enough space in /system to allow root. your best bet may be to flash chainfire's kernel which automatically removes the startup and shutdown sounds so frees up some space in /system, then you should have root. you can remove some of the bloatware like layar/aldiko/etc from /system and then reflash speedmod on top of that. I'm no expert at this though!
[Galaxy S I9000 Android Development] cha-ka-lak:
I had the same problems. After removing some unrequired system apps, there is enough diskspace on /system. The problems are gone.

T14 for JVT ?

I flash via ODIN the JVT deodexed by Ramad, then the kernel K15I-T13 with ODIN, and i had no problem.

Once the kernel is flash, you have to go in Recovery menu to root the phone, it install superuser+busybox.

Now i'm waiting for K15I-T14 : updated for JVT ... ;)
[Galaxy S I9000 Android Development] stef_ladefense:
+1 for JVT Version !
[Galaxy S I9000 Android Development] manudevil:
+2 for JVT version.
[Galaxy S I9000 Android Development] rG-:

[Galaxy S I9000 Android Development] Redwid:
Can't switch logger on (Logcat) in k15i-t13.

When pressed om menu item - there are nothing happens.

JVT firmware.
[Galaxy S I9000 Android Development] MiG-:
Same here on JVQ.
[Galaxy S I9000 Android Development] emeng87:
noob question here & im from Malaysia:

is it safe for me to flash this kernel, this is my phone info:

Firmware Version: 2.3.3 Stock Rom

Baseband Version: i9000ZSJV5

CURRENT KERNEL VERSION: 2.6.35.7-i9000XXJVO-CL182937 se.infra@SEP-51 #2

Build Number: GINGERBREAD.ZSJV5

please guide me all the expert here. tqvm.
[Galaxy S I9000 Android Development] MiG-:
Fixed this. It turns out I had no space left on system after performing root. I backed up a system app using titanium backup and then deleted it (just incase ;)).

Reboot into recovery, and try it again. Mine then says:

Enabled Options:
ANDROIDLOGGER (or something similar)

On reboot, if I do adb shell -> logcat I see the logs as normal :D

I assume the script fails due to not having space but doesn't tell us nicely. I forgot how nice the SGS screen can be with this Kernel. :D

Also, Voodoo Sound :D
[Galaxy S I9000 Android Development] GramiFIN:
What are the differences between these speedmod kernels?
[Galaxy S I9000 Android Development] hardcore:
K15I-T15:

- Updated modules from XXJVT

- Compiled using Linaro GCC 4.6 2011.10 toolchain

- SLUB max order set to 0
[Galaxy S I9000 Android Development] flo2lacanau:
Test of K15I-T15

K15I-T15 works fine on JVT. No bug or FC detected for the moment.

:)
[Galaxy S I9000 Android Development] LupusInvictus:
T15 with 2.3.3

Just installed T15 on 2.3.3 JVH [XEN]

Will report on any issues, not that I expect them ;)

Great work Hardcore....
[Galaxy S I9000 Android Development] ttf:
Salut Hardcore =),

As usual everything work as it should, thanks for your skill and time!

I use it with JVT deodexed and i'll report back if any issue.
[Galaxy S I9000 Android Development] fcck:
Unfortunaley i Switched to the Semaphore Kernel, Hardcore!

Had too much Sleep Of Deaths/BSOF, which was kind of annoying!

Anyhow i did enjoy having your Kernel! :)
[Galaxy S I9000 Android Development] CaraMuuu:
I've tried other kernels, but cannot use anyone of them for a long time; I always come back to hardcore's classic.

THANK YOU for continuing the development
[Galaxy S I9000 Android Development] michael_gmr:
Thanks for your update.
[Galaxy S I9000 Android Development] russell.nash:
Yes, all K15 kernels reboot. the first I tried was T9 which was the worst by far.

Stock JVK kernel never rebooted in the weeks I used it.

I have no flashable JVB kernel image, so I cannot tell that. If you have one I can check.

PS: It looks like I can check pretty easy if it crashes. If you want to try out several ideas, give me links to test versions.
[Galaxy S I9000 Android Development] jornbjorn:
i think ondemand is better if u use your phone very little... but conservative seems a lot better if u use to the things smartphones should ;)
[Galaxy S I9000 Android Development] hardcore:
Hmm I'm beginning to think it's something to do with the xxjvk firmware. I'm on xwjvb. Maybe the wifi firmware in the roms is different.
[Galaxy S I9000 Android Development] russell.nash:
Which makes the governor a first-class candidate for a configurable option :-)
[Galaxy S I9000 Android Development] theduckking:
I'm on deodexed stock jvk. Phone up since flash of K15b 20h (or so) ago, no reboots.
[Galaxy S I9000 Android Development] jornbjorn:
yes, u can use setcpu for that... i have tried, and it works without problem ;)

i only had one reboot earlier with the original 15C, just flashed the test2.

im on JVB and i never use wifi....
[Galaxy S I9000 Android Development] EseLoKo:
I did a clean upgrade to stock JVB and I suffered reboots too with K15A.
[Galaxy S I9000 Android Development] russell.nash:
Can you try this: link to a wlan (WPA), then leave the range by physically walking out of its range, wait a minute outside, then walk back into wlans' range.
[Galaxy S I9000 Android Development] madpete:
Mines been rebooting since flashing too, havent been able to put my finger on whats doing it so far...but I do have wifi switched on most of the time. Just flashed to test2 so will see if any different. On stock JVK at the moment.
[Galaxy S I9000 Android Development] arthos7:
i don't think it's the firmware because i'm also using jvb but deodexed version. 15C starts to reboot after 5 hours of use. now keep changing from 15A to 15C all keeps rebooting after a while....
[Galaxy S I9000 Android Development] theduckking:
Done, connected as expected, no reboot. I have a tasker profile to disable data and wifi a few seconds after the screen turns off and re enable it when the phone is unlocked. wifi sleep policy: when the screen turns off.
[Galaxy S I9000 Android Development] russell.nash:
ok, here is a check: my policy is on "never". can you switch to never (and delay tasker) and re-check if it crashes when leaving wlan range?

@hardcore: whats your policy setting?
[Galaxy S I9000 Android Development] theduckking:
Did that^^ It seemed kind of silly to turn off wifi, walk out of range, walk in again and turn it back on:D
[Galaxy S I9000 Android Development] hardcore:
I have mine on "never" as well. But I will manually turn off wifi once I leave my home (or area where I know I have wifi coverage).
[Galaxy S I9000 Android Development] theduckking:
How about the "Software Update" process which is rumored to cause battery drain? I deleted it on my phone.
[Galaxy S I9000 Android Development] liraindon:
Maybe reenabling the debug logs for the test kernels could give more data on what happens just before a reboot occurs?
[Galaxy S I9000 Android Development] russell.nash:
this is in fact the way I came to blaming wifi. I do the same thing, but when walking to the car in its port for a minute to fetch something I recognised the phone rebooting (sound). Obviously I did not switch off by hand because I only left the house for a minute. And I can reproduce that easily.
[Galaxy S I9000 Android Development] xfakexbloodx:
wew ??:eek::eek:

but i think its usefull to know the update for our apps ?

am i wrong ??
[Galaxy S I9000 Android Development] theduckking:
I guess it's not that one. I think it's for the samsung apps which I don't use.
[Galaxy S I9000 Android Development] hardcore:
Here are a few more versions to test for the reboot problem.

K15C-test3-ondemand: Same as K15C except switched to ondemand governor.

K15C-test4-dhd: Same as K15C-test3 except using pre-compiled dhd.ko from xwjvb kernel.

Would be great if those having the reboot problems can try them out, and see if either one of them fixes the problem for you.
[Galaxy S I9000 Android Development] hardcore:
K16-1:

- Reworked MDNIE driver (hopefully fixes black screen problem)

- Disabled warm/neutral/cold color selection
[Galaxy S I9000 Android Development] DocMarc73:
Can we use sgs kernelflasher to flas this one or does it has to be odin?
[Galaxy S I9000 Android Development] hardcore:
it's the same as other tar files. Should work the same as before.
[Galaxy S I9000 Android Development] jontoo:
No it's don't work with kernel flasher, and prevoios version on speedmod not work.Only with Odin
[Galaxy S I9000 Android Development] ZaneZam:
Hi hardcore,

May i ask you to update sources for download, latest is K15-T13.

Thx!
[Galaxy S I9000 Android Development] demonstone:
It always worked with sgs kernel flasher... I don't flash kernels with odin.

Sent from nobody knows where
[Galaxy S I9000 Android Development] madfix:
All kernels could be flashed with SGS Kernel Flasher. Without any restriction.

The only one to flash with CWM should be TALONDEV, for cleaning before flash...
[Galaxy S I9000 Android Development] LupusInvictus:
Thanks HardCore,

Did have the first black screen, last night.

But was still trying to figure out, if it was one of the new apps I installed before posting.

Will install and report on any issues.
[Galaxy S I9000 Android Development] ttf:
Same here the first time i experimented the black screen issue, with the K15.

In fact the phone is still working when it happen, the screen just doesn't respond anymore.

Will try the K16.
[Galaxy S I9000 Android Development] hardcore:
K16-2:

- Switched to default TREE_RCU (testing fix for black screen problem)
[Galaxy S I9000 Android Development] manudevil:
Thank you ! It is a very annoying problem... if you fix it you'll become one of the greatests in the Pantheon.
[Galaxy S I9000 Android Development] jontoo:
Are u try it by yourself or just speak by default, because I try to flash twise with SGS Kernel Flasher and it won't reboot :rolleyes:
[Galaxy S I9000 Android Development] miguelm75:
i did flash K16-1 and K16-2 by SGS Kernel Flasher and it booted OK.
[Galaxy S I9000 Android Development] jontoo:
Just preinstal sgs kernel flasher and now work fine and for me it was my mistake, now it is OK
[Galaxy S I9000 Android Development] flo2lacanau:
Someone have FC ou blackscreen with K16-2 ?

EDIT : no problem for me, i used ODIN to flash it
[Galaxy S I9000 Android Development] emeng87:
it work just fine with me flashing using SGS Kernel Flasher.:D
[Galaxy S I9000 Android Development] rizzy123:
does this kernal not have root with it?
[Galaxy S I9000 Android Development] ZaneZam:
After installation you can install it via recovery ;-)
[Galaxy S I9000 Android Development] ttf:
Yes apparently the blackscreen bug is still present. Had 2 of them since 24 hours with K16-2.
[Galaxy S I9000 Android Development] flo2lacanau:
outch ... still no black screen for me ... wainting for it to confirm !
[Galaxy S I9000 Android Development] EseLoKo:
I had a FC and a rebbot , few minutes ago with K16 - 2 in JVS stock ROM.
[Galaxy S I9000 Android Development] adamslast:
I had no FC or BS until now with K16-2 in JVT odex stock+.
[Galaxy S I9000 Android Development] burner07:
with blackscreen bug you mean SOD no? screen of death
[Galaxy S I9000 Android Development] ttf:
:) sorry but screen of death mean nothing to me. What i meant by "blackscreen" is an unresponsive screen or no screen wake up, if you prefer. When it happen the phone definatly work, put the charger in and you'll hear the plug "bip" sound (will try to access it with adb next time, to see if the phone is really working).

Something to do with the sleep/wakeup parameters maybe or the driver.

More data:

No others apps added or changed during the test:

JVT & k15i-t15 never experienced the bug

JVT & k16-1 happened 1 time during 2 days

JVT & k16-2 happened 8 times during 2 days
[Galaxy S I9000 Android Development] hardcore:
K16-3:

- Switched to Linaro GCC 4.4 2011.02 (testing fix for black screen problem)
[Galaxy S I9000 Android Development] LupusInvictus:
Black screen

Had another blackscreen this morning.

Hardcore beat me to it again with K16-3.

Will install and report on issues.

Btw never had a problem with K15-15

Thanks HardCore.
[Galaxy S I9000 Android Development] flo2lacanau:
No FC or Black Screen for me with K16-2, so I keep it !
[Galaxy S I9000 Android Development] hardcore:
K16-5:

- Changed compiler optimizations

This version is smoother than K16-3.
[Galaxy S I9000 Android Development] flo2lacanau:
K16-5 !!??

Hardcore, tel us if we have no pb with K16-2, should we change for K16-5 ?

Edit : "This version is smoother than K16-3." OK hardcore !! thanks

Edit 2 : K16-5 woks perfect for me ...
[Galaxy S I9000 Android Development] ttf:
Thx for your fast work. I don't exactly know what you changed on the K16-5 except the compiler, but this is blazing fast!.

Anyway let's hope that annoying bug is gone. Will report back in a few days.

I use K16-2 for 2 days, no issues. Battery is very good.
[Galaxy S I9000 Android Development] ttf:
Oh that's an interesting question =). i was using ext4, but you right, i switched to RFS since the first K16. I don't really see how it could be related, but well who know =D.

I'll switch back to ext4 to see it react.
[Galaxy S I9000 Android Development] hardcore:
Try ext4 for both SYSTEM and DATA. I suspect it might be something to do with the write flush tweaks, as pikachu1 was mentioning.
[Galaxy S I9000 Android Development] $omator:
i had bsod on clean (none kernel flashed) on all firmwares prior to jvt

now it seems theve done some fixmagic for jvt as i never experienced that on jvt (with cfroot)
[Galaxy S I9000 Android Development] ttf:
Ok i'll test that, thanks again =).

Anyway if the "flush tweak" is the culprit, any chance to get a kernel version without it? (or maybe an option to enable/disable it?). I know it sound useless, but as you know the system file switching can cause big trouble sometime (passing from a kernel to another/lack of space for backup etc) and the JVxx perform pretty well now with RFS.

What you think?
[Galaxy S I9000 Android Development] hardcore:
I'm going to upload a test version k16-6-test1 to the first post, which has different/lower IO tweaks. Can see if that helps.
[Galaxy S I9000 Android Development] ttf:

Downloaded, i'll see first if the ext4 do indeed definatly resolve the problem, 2 days test, then i'll switch to the test version and report back.

[Galaxy S I9000 Android Development] BusterSG:
does speedmod support CM7? i guess not...

are there any CM7 kernel based on speedmod's work?
[Galaxy S I9000 Android Development] ttf:
Good news!

Not a Single black screen with the K16-5, using Ext4. My question is how the "flush optimisation" can interact such a way on the screen (the phone is definatly alive when it happen, we can access it with ADB).

Will install the K-16-6 tomorow with RFS to see how good it is!
