geez, I didn't know that until I saw this post. :(

Actually, it "sees" it, but for some reason just can't access it.

Yes it is a nag, hopefully this can be fixed.
[Galaxy S II Original Android Development] Orpheus1120:
I'm on VR2.0 and n2.0.1 and still no dice. I'm using the L2TP/IPSec PSK VPN option. Reverted back to Cf-Root and it was a go?

Dumbfounded. :confused:
[Galaxy S II Original Android Development] reidar.ostrem:
Have not tried any other vpn options than pptp, works with n201 and cf root. My only problem with any other kernel is wakelocks, that is not a problem on CF 4.1

[Galaxy S II Original Android Development] Hacre:
Then your phone isn't stable at 800mV @ 200MHz.

Sure I'll get 2.0.2 posted later today.

EDIT: IKCONFIG is already enabled and it has nothing to do with VPNs.
[Galaxy S II Original Android Development] Hacre:
2.0.2 posted.
[Galaxy S II Original Android Development] da13:
I know IKCONFIG doesn't have anything to do with VPN. I couldn't see /proc/config.gz, but maybe I was using older version. Seeing what's there makes it easier to add more feature requests :)
[Galaxy S II Original Android Development] Hacre:
It's there and has always been there. I'd suggest you take the time to learn more about kernel options if you're going to start asking for them, since CONFIG_IKCONFIG=y doesn't put anything into /proc/config.gz anyway, the option CONFIG_IKCONFIG_PROC=y does (which has also always been enabled).

All CONFIG_IKCONFIG does is allow you to extract a config file from the zImage itself.

[Galaxy S II Original Android Development] Testraindrop:
Hi Hacre, maybe this will be a post 5 post ... :)

I don't know much about Kernel development, but I couldn't figure out why you aren't using CWM Recovery 4.0.1.4. or is this planned for future releases?

Also have you considered or already disabled some debugging features like Hardcore did in his kernel? That seem to help with Android OS Battery usage (I know AOS must always run and the sum will always be 100%...)

Using 2.0.0 without any problems so far on LeoMar75 2.2 Rom, keep up the great work :D
[Galaxy S II Original Android Development] Hacre:
Is there something in CWM 4.0.1.4 we should be using?

Debugging features in the kernel are already disabled. Have I disabled adb/logcat? No. Will I? No. I'm at 50 hours uptime on my phone with just under 40% battery remaining. I see no battery issue. Whether the life can be slightly improved or not, removing a key debugging function from the land of custom ROMs is a stupid idea.
[Galaxy S II Original Android Development] Testraindrop:
Honestly I don't know :o, but newer = better? :D

Nevermind, the version you are using working also just fine.

Yeah, I also have no problems with battery life. Have 25 hours and 72% left :)

Was just an idea, hope Samsung will release a 2.3.4 source soon, apparently they fixed some stuff there.
[Galaxy S II Original Android Development] AvRS:
I saw posts saying the speedmod kernel has removed the AOS bug (something I don't believe is actually real and has been manifested by one person and spread like a plague into people's thinking). Is it not that he's hiding the AOS reported usage rather than solving anything so more to fool people into believing it's solved. I pay no attention to the %'s as it told me a little while ago my dialer had taken 13% when it had only kept the phone awake 5s from 5hours uptime, a calculation that is clearly not true. So pinch of salt is all I say.
[Galaxy S II Original Android Development] Hacre:

hi there. With 2.0.2 I get a sudden reboot when trying to make a pptp vpn connection. I cannot provide a log because I am on the road atm. Could do it when at home if required.

Cheers
[Galaxy S II Original Android Development] adyscorpius:
Hey Hacre,

Could you build a CM7 supporting kernel with all your tweaks and support for OC/UV?
[Galaxy S II Original Android Development] SimpleNick:
running 200MHz-1600MHz "OnDemand" since two, three days ago, not one random reboot, may i ask where/how can i locate the instability?
[Galaxy S II Original Android Development] veyka:
In CWM, fix for the inability to access the external SD card, so people say.

And disabling adb and logcat is rather silly, its not like most people can/will log, but still you are losing a valuable source of info about the workings of the rom.

(i did try the kernel, wasnt my cupa tea)
[Galaxy S II Original Android Development] Hacre:
CM developers have asked that people refrain from making custom kernels for CM7 on the SGS2 until CM7 is at least considered stable on the SGS2. I understand this request and intend to abide by it.

So, no.

Actually it's a modification to the initrd that makes mounting external_sd possible. I'll look into it later.

Well without any logging running while you try to connect to the VPN I'll have no idea what the cause is, so yes logging would be required. :)
[Galaxy S II Original Android Development] mr.gibran85:
i'm curruntly at litening 4.0 KG3 which is running Ninphetamine-2.0.1 Kernel so was wondering if updating to 2.0.2 cause any problem ?
[Galaxy S II Original Android Development] Sonic7:
Yeah you will notice the following problems:

More VPN features added.

JHash updated to version 3.

[Galaxy S II Original Android Development] steveman29:
Hello Hacre thank you for theis great kernel! Could you add an extra step before 1600? Something like 1504 or 1540, beause some of us can't run the device on 1600 but it runs ok on 1504-1540.

Also could you make an extra version with the gpu set to 400 mhz with 1100 voltage? I am willing to try and i think many other users are. Also i tried this setting with tegrak overclock and it runs ok.

Thank you in advance.
[Galaxy S II Original Android Development] Hacre:
No I won't add a 1500MHz step. Doing so would increase battery drain for people who use 1600MHz. To eliminate that we'd need to get rid of the 1400MHz step, but then what about all the people that can run at 1400MHz but not at 1500MHz?

The difference between 1400MHz and 1500MHz is negligible, so if you can't run at 1600MHz you have the following options:

Run at 1400MHz

Use a different kernel.

I don't really care which. With the speed table I'm using, we cater for the broadest range of people, those that have phones that can just about manage to clock past 1.2GHz and those with golden phones that can run at 1.6GHz while minimising the battery drain for those using 1.6GHz.

As for the GPU it's been stated many times in this thread that it is on our to do list.
[Galaxy S II Original Android Development] tolis626:

[Galaxy S II Original Android Development] zikarus:
Ok, small update concerning bt rSAP connections:

Had the posibility to try out a bit more. Starting with Litenin 3.2 and Ninphetamine 2.01 vs. Tegrak v11 (KG2). Same result as before - instable rSAP with Ninphetamine 2.01, stable with Tegraks v11 (KG2).

Today I switched over to Litenin 4 (being a KG3 Rom). This time Ninphetamine 2.01 and 2.02 as well as - first time - Tegraks v11 (KG2) could not deliver stable connections !

This may lead to the clue, no ? Could it have to do with the initramfs ? May try out Tegraks new, just released v11 (based on KG3 initramfs) tomorrow. First I will have to flash Litenin 4.1 ... ;-))
[Galaxy S II Original Android Development] d3l1:
Sorry in advance for the noob question but can I use that kernel with my stock kf3 rom?

Sent from my GT-I9100
[Galaxy S II Original Android Development] Hacre:
If Tegrak KG2 delivers stable connections with one ROM but not another, why would it be the initramfs?

READ THE FAQ ON THE FIRST SODDING PAGE OF THE THREAD!
[Galaxy S II Original Android Development] zikarus:
Tegraks v11 (KG2) delivered stable connections with a KG2 ROM.

The first time I could not get stable connections being on Tegrak v11 (KG2) was with Litenin 4 which is a KG 3 ROM. Therefore my thought (and because the new Tegrak v11 - which I could not try yet - seems to be mostly the same as before besides being based on KG3 initramsfs now)...
[Galaxy S II Original Android Development] Hacre:
You're not making any sense. You said Tegrak v11 (KG2) gives a stable bluetooth connection on a KG2 ROM but not on a KG3 ROM. Therefore the initramfs hasn't changed.
[Galaxy S II Original Android Development] tolis626:
No I'm not.Thankfully.In fact,hopefully. :p

Well,I love some of the Greek people.Have you seen our ex Prime Minister?Our Minister for Economics?Or,the best one,our old Honorary Minister or whatever he's called(If not,search for Μητσοτάκης or Mitsotakis on Google.Be sitted and have an ambulance stand by in case of a heart attack :p ).Or better,let me give you a taste of what I mean.

@Major Sarcasm

To whose mind don't our financial stuff come in?It's more ****ed up than a hottie hit by a speeding track.Then hit by a meteor.Then shot with a shotgun in the head.Then burned.You get the idea. :D

No,say whatever you want about Greece's economics.I'll only agree. :p
[Galaxy S II Original Android Development] tolis626:
On another note,who would like to see all the "Post 5" stuff covered by Azrienoch or SamCaplat on XDA TV?I for one would love to! :D
[Galaxy S II Original Android Development] zikarus:
Hmh maybe I could not express myself the way I should. Forgive a non-native tongue.... I was just trying to highlight, that using the KG3 ROM with a KG2 Tegrak kernel failed to deliver stable rSAP which was the first time this did happen to my device. The only obvious reason for this behaviour seems to be the fact, that during the latest test the kernel and ROM versions were NOT identical (as in my former tests). Since you have cleared up that bt wise Ninphetamine and Tegrak should not differ, the latest failure of Tegraks KG2 kernel on a KG3 ROM led my noob mind to the conclusion, that the mere difference between Tegraks (old) v11 KG2 and the new v11 KG3 being that the latter is based on KG3 initramfs may give a hint. One could be sure, if the new KG3 based Tegrak works fine with Litenin 4.x which I have not tried yet. Anyways oao for today...

[Galaxy S II Original Android Development] Hacre:
Great stuff, I'll update the OPs. Does Voltage Control control only voltage or speeds as well?
[Galaxy S II Original Android Development] tolis626:
No,we do worry.We worry because some...politicians(I'm not allowed to swear enough in these forums) are between your money,our money,and what would save us all.Those guys are either far too stupid to be in charge of a country,or too smart and control us all the way they see fit.Either way,they don't do what they are supposed to do.

F*ck what you hear in the news.You know what the Greek taxpayer pays?You don't wanna know.Imagine the level of incompetence of our politicians who can't make things at least start going to the right direction with all that money.

Then there's Mrs Merkel...No comment because German guys are in the forums too! :)

[Galaxy S II Original Android Development] Hacre:
This is by design. Since MIUI likes to look like an iPhone, I figured if you hold your SGS2, with MIUI running, WiFi won't work.
[Galaxy S II Original Android Development] jerdog:
or if you hold your SGS2 while running with MIUI a rift may open in time and space and a few million iPhone's will actually begin to make and receive phone calls thus canceling out our very existence and the world will collapse on itself. So for the sake of the rest of us - and not to mention treating your SGS2 with respect - don't use MIUI! Buy an iPhone if you want MIUI.

Yes,give up on 1.6GHz.If it doesn't run it at 1.5V,then your CPU is not meant for it.And even if it did,you are pushing the envelope far too much with 1.5V.I'd suggest you try 1.4Mhz,it's insanely fast too. :)

Maybe your phone cant go that high? Mine runs 1,6Ghz@1400mV, and even 1375mV at times but i havent tried much more then som benchmark runs.

Well,I think I saw these nice gel cases the other day that have an inner layer that has liquid nitrogen trapped between two layers of the silicone.Phone looks good in them,it's just that anyone using it must wear the protective 25mm thick gloves so that their hands don't completely freeze.They are on the phase where they are trying to get the phone to register touches through the gloves.That is IF they manage to unfreeze the phone.After that,I want to overclock to 4.2GHz(I am conservative with overclocks,4.9GHz is too high). :p

[Galaxy S II Original Android Development] SimpleNick:
in the event where it freezes due to undervolt, press and hold the power button until it power down, power up again, and u shall have a short window time to come back to SetCPU to tweak the settings.

the key is, always leave at least a stepping up and a stepping down to the MHz stepping that you are testing, for the CPU to hover around, to buy you that window time.

i did 25mV stepping for freq > 200MHz, too lazy to fine tune it at smaller steppings.

my processor doesn't reboot or freezes with 760mV@200MHz.. guess a slightly hungry horse is a good work horse..

and my question on the software cap to 800mV still not answered .

if there's a cap, nothing should matter even the lower i set, yet it does and it does freeze if go lower than allowed (750mV in my case).

so, there's no cap..?

pptp vpn

Here are my logs on the pptp vpn reboot (one with CF-Root-SGS2_XX_OXA_KG2-v4.1 that connects successfully and one with Ninphetamine-2.0.2 that reboots). I hope they are useful (not sure if I should truncate.. or if its missing sth at the start, but they are getting big really fast). Just tell me if I should log differently.
[Galaxy S II Original Android Development] Hacre:
Um, no. Besides it doesn't hurt to have more than one kernel around. As for merging his ideas, jhash3 has been on our to do list for a while, we just got side tracked with the random reboots in 1.x. Take a look at netarchy's nexus-s kernel, it's had jhash3 for some time.

Thanks I'll take a look.

EDIT: There's absolutely nothing useful in those logs whatsoever.

Don't edit anything. Just do the following:

adb logcat > vpn-logcat.log

adb shell cat /proc/kmsg > vpn-kmsg.log

You'll need two terminal windows for those commands, one command per window. Then start the VPN, the logs will automatically terminate when the phone reboots. Then zip up and post the two files here.
