If they do not work for you, please give us some debug info (errer after insmod? error after ntfs-3g?).

Good luck!

Just noted an issue. I went back to 1.8 for a compare/contrast to make sure my impressions of 2.0beta7 weren't placebo. Came back to 2.0 and auto rotation was not functional. Turned it on/off, and rebooted to no avail. I cannot recall if I had this issue the first time I used beta7 or not.

No problem, after all, it was the second part of a long post. Just report back when it works / doesn't work ;-). For me, it works starting with the first Siyah-kernel I tried (which was something like 1.7.7 or so).

Furthermore, I did not know that this forum joins double-posts by default... Can this be turned off for cases like this, when you address different persons?

[Galaxy S II Original Android Development] AndreiLux:
Gökhan, can you please increase CONFIG_LOG_BUF_SHIFT to 19 like this? Also, if you having noting better to do it would be great if the system printed out a message to dmesg with the current timestamp when the CPU wakes up from sleep :p:o

Edit: And it would be great to have CONFIG_PM_DEBUG set. For that matter it would be better if you could make a separate debug kernel with LOG_BUF to even higher, say 22.
[Galaxy S II Original Android Development] bala_gamer:
So smooth with beta7, and im happy to inform that the screen warming issue when hearing songs in background is fixed.

Edit:

Id really love to see either a custom slider for overlocking or some 1.5 ghz clock, i know gokhan has already made a reply regarding this.

Asking the same again bcos i have seen many users unstable at 1.6 ghz, so a custom slider would give them an oppurtunity provide what would be their best setting,also "the custom slider" for overclocking is in the todo list, am i right?
[Galaxy S II Original Android Development] Entropy512:
After testing, I don't think CONFIG_PM_VERBOSE is going to be that useful, at least not yet. It's REALLY spammy. Wait a sec, you must've edited that just as I clicked quote...

I'm going to try and figure out some way to print wallclock time on resume, might make gokhanmoral's job easier.
[Galaxy S II Original Android Development] :
Keep in mind that your battery indication can be funky at first as the kernel wipes your phone's battery stats, assuming you charged to 100% after flashing. Regardless this kernel is excellent on battery.
[Galaxy S II Original Android Development] Entropy512:
Wiping battery stats does nothing to our state of charge estimates.

gokhanmoral - I suggest reading through drivers/power/max17042-fuelgauge.c - you'll see that our fuel gauge driver has no provisions for loading battery stats or heuristics, and while it has advanced features not present in the 17040, they aren't enabled, and it is behaving functionally almost identically to the 17040, which was specifically designed not to require calibration. (Google MAX17040 for more information.)
[Galaxy S II Original Android Development] bala_gamer:
One good question regarding development, can we monitor the temperature of our cpu? Does s2 have those appropriate sensors? Awaiting reply
[Galaxy S II Original Android Development] :
Thanks for the clarification, I was going by the statement below, from post #1, and funky battery behaviour I've noticed on the first charge after a new kernel. Google will have to wait until I fire up my laptop.

I hope it works out for you.

I could not use KI4 so I am glad to hear they are about the same. The reason I like is not just for about better signal but about good quality signal. Your mileage may be different due to our differences in location.
[Galaxy S II Original Android Development] el_tute:
I found the values, but, how can I change them?

I can't change r/w permission with root explorer in order to change the file charge_current

thanks in advance and great kernel!!!
[Galaxy S II Original Android Development] hausmanis:
If i have a working "version" of touch-X power+ with the included kernel that is optimized for that rom, will i still benefit from installing your newest non optimized beta ?
[Galaxy S II Original Android Development] eybee1970:
for all you guys playing around with UV in SetCPU....don't check 'Set on boot' til you are not sure the values running stable! Otherwise this will cause one wakelock and/or reboot after the other when values are too low --> I guess this is main reason for some of you experiencing lots of reboots!
[Galaxy S II Original Android Development] :
Still stable with values posted before, you can release this mofo as far as I am concerned.

Will you leave bfq-v2 for next version then?
[Galaxy S II Original Android Development] diddsen:
can confirm this...

the changes wount be saved... i have also rootexplorer, set full permissions and r/w.

the file seems saved, but after open again the old values in :-(
[Galaxy S II Original Android Development] gokhanmoral:
You only need to echo "1000 1000 450" to that file
[Galaxy S II Original Android Development] kwerdenker:
Guys, these aren't real files. These are just stubs by the system to read/write from/to hardware registers. You have to use adb shell or terminal emulator in superuser mode and then do

echo "1000 1000 450" > sys/devices/virtual/misc/charge_current/charge_current

This will get reset on a reboot, so if you want it permanent you'll have to add it to a init-script.

Edit: Sorry gokhanmoral, didn't check for new posts before hitting reply ^^
[Galaxy S II Original Android Development] yay1974:
@gokhan

100 mhz with default voltage locked the system with ondemand governor and caused spontaneous boots in Batista 3.7.7 so I reverted back to abyss 1.4 since it supported oc daemon too :(
[Galaxy S II Original Android Development] gokhanmoral:
Batista rom doesn't count. It has something that conflicts with this kernel but I don't know what it is
[Galaxy S II Original Android Development] galanakop:
thanks very mootch
[Galaxy S II Original Android Development] el_tute:
Thanks kwerdenker and gokhanmoral for your replies.

I never did a script for init.d only modified some of them. So, could you please upload your current script, so if I want less speed I can modified myself?

Thanks and sorry my rusty English and my ignore in these matters.
[Galaxy S II Original Android Development] kwerdenker:
I don't use it, so I don't have it in/as a script but have you seen one, you have seen them all ^^ Just save the following text in the code block as a file (no file extension!, for example 95chargingvalues) and copy it to /etc/init.d/. Then change permissions so it's executable (via shell this is done by "chmod 777 95chargingvalues"), most root-fileexplorer can do this via long press on the file I think.

#!/system/bin/sh

#customize voltages to your values

Hi guys,

I was curious to try this interesting kernel. I'm on LeoMar Rom with speedmod T40 kernel.

Just flashed your 1.7beta2 and I lost root (you are mentioning this is an auto-root). What can I do?

Thanks!
[Galaxy S II Original Android Development] kwerdenker:
This is curious. I'm also on Revolution and I didn't experience anything like this. How did you flash the kernel? Via CWM App, via CWM directly or via ODIN?
[Galaxy S II Original Android Development] fish80:
Thanks for your feedback. Flashed via CWM App...
[Galaxy S II Original Android Development] el_tute:
Many Thanks !!!!!

last question,

AC is obviously AC charger

USB, ok, is usb

but wtf is MISC ??

thanks again
[Galaxy S II Original Android Development] kwerdenker:
That's strange. Done this the same way for all kernel versions and never had this kind of problem. Could you try reflashing in CWM with the zip from this post and see if this maybe helps.
[Galaxy S II Original Android Development] android_888:
I am also on Revolution and have no problems..
[Galaxy S II Original Android Development] fish80:
Ok mate, I'll try in a couple of hours (now can't shutdown my phone) and let you know!

However with all stock settings (obviously can't change anything because the root) I feel everything very smooth... Very promising.

Thanks again.
[Galaxy S II Original Android Development] gokhanmoral:
try flashing a CWM flashable su package.

it seems that you had a problem with permissions.

try clearing cache and dalvik cache and fix permissions. that may fix it.

I don't know why that happens but it happened to me several times with other kernels
[Galaxy S II Original Android Development] eukaryote:
Just a note: Orbot (from the tor project) doesn't work with siyah kernel (only tried it on version 2 so far), but does with the stock CM7 kernel.
[Galaxy S II Original Android Development] lpsi2000:
Come on, you could solve that problem your self by flashing cfroot when you need to do a restore from 4.0.x.x. By the way how often are you using the restore / backup? And if you are using backup / restore a lot then why bother maintain compatibility when you can very well use the latest version.

I personally do lots of backups and restore. If I get an MD5 error then I will flash the right kernel, then reboot to recovery again, then proceed with the restore. Also the latest version seems to work fine and provide additional capabilities that are not in 4.x.x.x version.

Bug kernel Siyah

Hello guys and sorry for my English, indeed, sorry google translator for his English, today, after so much hard work, I discovered a bug in the kernel 1.8 Siyah final hope is not dragged to version 2, I tell you. Always use an alternate Launcher, Launcher Go ita former, since there is I, I never had any problem except the day I put on the Kernel Siyah (but until now I did not know) 1.7.8 from the final version 1.8. Virtually replaced the various Rom, but it always kept my kernel in consumption because I liked it. It often happened that after turning off the terminal to restart, I was not previously installed applications installed, so a little blame on the Rom, a little guilty at Go launcher, a little blame on the microSD, various formats, I came to the result, today , that the blame lay with the kernel. What have I done for the pleasure of experiencing, I changed my kernel, and I installed the Nimphetamine, to restart, voilà, all programs applied. So, I doubt arose, turned on again and the terminal for 10 times, the result, all applications affixed, the Siyah Reinstallai 1.8, guess what, I switched off and back on the terminal, and 10 times I have found some application uninstalled. I put the Nimphetamine, turned off and on again for 10 times, no application is uninstalled. Now I wonder, a kernel, it has to do with applications? Why after what happened to me, I challenge anyone to tell me otherwise. Davo blame the Rom to Go launcher, the Micro SD, that tomorrow was despite being new, I wanted to go to buy back, only to be understood only by accident that whole mess was the Siyah. I have not tried the version 2 of the Siyah, but I wrote this to prevent this issue from being dragged for this and future versions. Thanks

PS: This problem occurs only with the applications installed on the micro sd and not on those installed on the terminal.

Maybe a conflict with the Launcher only alternative?

[Galaxy S II Original Android Development] vnvman:
Yeah, standby battery life is awesome on this kernel: it's much better on that side compared cm stock one. I'd just love to have a gui for gpu oc-uv and the other tweaks, but using the scripts isn't hard at all either.

Switched back from Siyah kernel 1.8 to the stock XXKI3 kernel and the clock drift problems appear to have gone away. So something about the Siyah kernel is causing the clock to fall behind by about 30 seconds an hour on my phone.
[Galaxy S II Original Android Development] tolis626:
I want you to be completely honest with me,alright?Do you see anything about ondemandx in that thread?I'm either very retarded,or you just copy/paste the thread's url each time you see the word governor. :)
[Galaxy S II Original Android Development] tonysac:
Lol..if I remember right the only difference between ondemand and ondemandx is sleep profile for the second one...but the strange for me is that the ondemand has no lag and ondemandx seems to have a little bit lag...seems strange if the only difference is the sleep profile...

Save water..drink beer...
[Galaxy S II Original Android Development] tolis626:
I try to stop being "sarcastic" if I can call it that,but some are provoking me. :p

Anyway,that's what I was saying man.Ondemandx lags for some seconds after idling(doesn't necessarily mean sleeping) but then becomes super-smooth,while ondemand is relatively smooth all the time.Strange.

So,if someone really knows,besides the sleep profile and the "X"(Obviously :p ),what are the differences between ondemand and ondemandX?
[Galaxy S II Original Android Development] bala_gamer:
No one bothered to answer these???
[Galaxy S II Original Android Development] pappschlumpf:
I think you're right, there must be more difference between ondemand and ondemandx. Around 2500 Quadrant benchmark points for example. With ondemandx 1500, with ondemand over 4000 with 1400 mhz. Running the benchmark several times isn't changing the score for ondemandx.

One more problem. I don't know which version it was, but this one is behaving like a previous version in one point. Superuser rights for. for example LBE Security, Widgetlocker and so on are granted a very long time after unlocking the device.

Anyway, my favorite kernel!
[Galaxy S II Original Android Development] ludow:
Okay. I just like to use CF's CWM manager. If thats compatible.
[Galaxy S II Original Android Development] jsompis:
I also have clock problem, it slow down about 3-4 mins per day.

[Galaxy S II Original Android Development] tolis626:
Yeah.OndemandX seems to have a tendency to scale down too much and it does it quickly.That's a deal breaker for me.

Btw,I am using the same settings for both governors(50000ms sampling rate and 75% up threshold).
[Galaxy S II Original Android Development] gundin59:
Exactly such problem sunce time
[Galaxy S II Original Android Development] tolis626:
I don't know about you,but I lika!Beta7 ftw! :D

EDIT:Guys,I'd like to point out that,with our devices having dual-core CPUs,the most valid synthetic benchmark is probably Smartbench.Quadrant it ****,we can all agree on that one.Antutu is good,but,unless I'm missing something,it's not multi-threaded.Other than that,the only benchmarks that do show things that matter in everyday performance are those that focus on a certain aspect of the device,like Linpack for CPU and Nenamark for graphics.
[Galaxy S II Original Android Development] efegue:
Unfortunatelly, the kernel might have good battery life, but performance wise.. it's not for me :(

Dude,what governor are you using?If you are using one of the battery-friendly governors it's bound to not be as smooth.You want smoothness?Try ondemand(Not ondemandX) or lagfree.It should be smooth as **** if you don't use anything less than 1000Mhz.Maybe even 800MHz.I for one use 1.6GHz and it makes the iPhone turn green from envy. :D

I have uploaded beta8.

I hope time related problems will be solved in this beta.
[Galaxy S II Original Android Development] vnvman:
What i like about this kernel is how smooth it is at lower frequencies. Also, the gpu runs very well and it's very responsive in games: i can run all of them @500 mhz with perfect smoothness. This, coupled with severe gpu uv allows me to have my daily bit of gaming without draining all the juice. Also, the device feels almost cold in the hand, even after a long session, and that's just amazing. If some Siyah tuning/whatever app will ever be released i'll buy it as soon as it hits the market. This is pure awesomeness people, get some.
