Cool... runs fine but it seems to have the same problem SetCPU has on my device where the min/max clocks get reset every so often when using the "ondemand" governor. Any idea whats behind that?
[T-Mobile Samsung Galaxy S II SGH-T989] Romanbb:
Max stays fine for me. It's the min that resets incorrectly... I'll try and find the cause of this

romanbb, you planning on committing any of your changes in the last 3 days to git? it's 2 kernel revisions behind now. I sent yah a pm but maybe you didn't get it.

Id like to take a look at your tree compared to mine and see if i can pin down a few issues i've been having as well as see if i can spot where i am going wrong with bln.

Awesome battery life, same here my phone doesn't like the 1.89.. Roboots:/

---------- Post added at 10:09 PM ---------- Previous post was at 10:05 PM ----------

How much should I raise it up to?
[T-Mobile Samsung Galaxy S II SGH-T989] Romanbb:
I don't know, every phone is different. If you're using system tuner just raise it up by 12.5 and see if it works. If not raise it by another 12.5
[T-Mobile Samsung Galaxy S II SGH-T989] bubbabfp:
I tried raising it up to 1400+ still nothing:(

Just jumped off stock and took the plunge. No problems so far juggernaut 2 and latest kernel. Handling 1.89 smoothly. Tweaking voltages now. Thanks guys. running
[T-Mobile Samsung Galaxy S II SGH-T989] hah2110:
Isn't it already undervolted? I don't get it... I just want good battery life.
[T-Mobile Samsung Galaxy S II SGH-T989] hazard99:
Wouldnt best battery come from stock ?
[T-Mobile Samsung Galaxy S II SGH-T989] kenvan19:
No. its set to give maximum stability to the widest possible group of devices. Under volting can sometimes be unstable for some devices but it uses less power as well.

Also, I tried upping the voltage for 1.89 with no luck. It appears i'm sol as well :( oh well, still a great kernel.

My point was that everyone is making modifications but wanting super duper battery life. Its like putting a modded ecu in your car and expecting better gas mileage while driving 90 mph all the time.
[T-Mobile Samsung Galaxy S II SGH-T989] mikeyinid:
If you flash this kernel and only mess with your Max clock speed you will get the best possible battery life. Not even the stock kernel is better. Roman uv'd jugs so there is really not a need to go down any more. If you think you can squeeze an extra couple of minutes of battery life reducing voltage even more, be prepared to have issues.
[T-Mobile Samsung Galaxy S II SGH-T989] kenvan19:
That's not the best example but I'll ruin with it: the difference here is that under volted kernels DO do that. Its like that new ecu also changed how much fuel was injected to obtain a set speed; lower the amount of fuel and up the amount of air then you WILL get better fuel economy.

Is it a bad thing if i modify init.qcom.post_boot.sh and change min clock speed from 384 to 192? 192mhz would stick this way but not sure if it's a good idea.
[T-Mobile Samsung Galaxy S II SGH-T989] bucrx7:
Roman actually increased the mv back to stock like mv as stated in the 0.2 change log.
[T-Mobile Samsung Galaxy S II SGH-T989] bucrx7:
Your battery life should be good with jug rom and kernel. I optionally undervolted to see what I can get out of my phone.
[T-Mobile Samsung Galaxy S II SGH-T989] mikeyinid:
OK. I still get better battery life than I ever did with the stock kernel

Oh for sure 9 hour and on 75% of course it depends on usage during that time but def see a difference
[T-Mobile Samsung Galaxy S II SGH-T989] djy:
Thanks Roman. After I flashed Jugs 0.3, each time when i wake the phone, a white horizontal line flashes in the middle of the screen. I have CRT animation off. I am also running system tuner with the following changes (governor = on demand, max cpu = 1.72, min cpu = 384, re-apply CPU settings = init.d script, no other tweaks). Anyone else have it? What is this? It is slowing the wake process down.

Edit, I just realized the cpu settings are per core, not min and max. Just uninstalled system tuner and rebooted. The line disappeared.
[T-Mobile Samsung Galaxy S II SGH-T989] Romanbb:
It's an issue with Juggernaut that very few people have been seeing.

Use http://db.tt/qO9Cdk3N as a temporary solution. Rename it to services.jar and replace yours in /system/framework. Adb or root explorer should work. Reboot after.

I'll try and get us a proper one in Juggernaut later today.
[T-Mobile Samsung Galaxy S II SGH-T989] djy:
See my edit. I uninstalled system tuner and the anomaly disappeared. Gonna play with it more after work.
[T-Mobile Samsung Galaxy S II SGH-T989] :
Sorry if this seems redundant. I've been reading but want to make sure I have the settings right. Is this how it should look like? init.d on CPU? And I do have the min reset once in a while. it seems like it has bipolar disorder.
[T-Mobile Samsung Galaxy S II SGH-T989] Romanbb:
Use my app (linked in the first post below the dl link). Much simpler. The minimum will not stick on 192. That's a kernel issue (core 2 will stick on 192, but core 1 will reset to 384).
[T-Mobile Samsung Galaxy S II SGH-T989] Pellel2:
go to CWM. wipe all caches and fix permissions. reboot and that should fix it
[T-Mobile Samsung Galaxy S II SGH-T989] -Mr. X-:
its not a kernel issue, its the permissions that are set on the script that you dont edit or remove from your roms.

its setting root:system on /sys/devices/system/cpu/mfreq and perm 220 on it. this makes the min freq adjustments not still with apps that are not in the group root:system

there is quite a large bit of crap in that script that i've mentioned a few times should be edited out at the very least.
[T-Mobile Samsung Galaxy S II SGH-T989] :
Thank you. This definitely flows.. Seems snappier . System tuner was causing some slow downs.
[T-Mobile Samsung Galaxy S II SGH-T989] Romanbb:
Can you please refrain from posting ****, atleast in my thread, that you can't backup with proof or actual knowledge.

Thanks.
[T-Mobile Samsung Galaxy S II SGH-T989] faux123:
Please STOP spewing crap and non-sense about kernels.

mfreq is used to FORCE MAX FREQUENCY for CPU governors and has ABSOLUTELY NOTHING to do with min frequency adjustments. It is set to root write only as protection against accident overrides from user space binaries.

here's the code snippet from cpufreq from the kernel:

static ssize_t store_mfreq(struct sysdev_class *class,
struct sysdev_class_attribute *attr,
const char *buf, size_t count)
{
u64 val;

if (strict_strtoull(buf, 0, &val) < 0) {
pr_err("Invalid parameter to mfreq\n");
return 0;
}
if (val)
override_cpu = 1;
else
override_cpu = 0;
return count;
}

static int set_cpu_freq(struct cpufreq_policy *policy, unsigned int new_freq)
{
int ret = 0;
struct cpufreq_freqs freqs;

freqs.old = policy->cur;
if ([COLOR="Red"]override_cpu[/COLOR]) {
[COLOR="Red"]if (policy->cur == policy->max)[/COLOR]
return 0;
else

You guys have plenty of your own kernels, why do you want this one? It won't -- the two phones use two different processors so the kernels are very very different.

Hey, can you get this kernel to work on my Galaxy Nexus Prime and also on my wife's Galaxy S IXV. Also, I noticed there's some script that needs to be changed. Sesssh, I don't know how you guys do it? Patience truly is a virtue.
[T-Mobile Samsung Galaxy S II SGH-T989] Strapt:
ok I got to ask .. why is it that when I do an overclock kernal on either the stock ROM or the Juggernaut one that my antutu and cf-bench speeds drop by 1000 each? now i know that people say that these are just numbers and all . but wouldnt they go up if the performance of the phone goes up? I have seen someone else running the Juggernaut setup with this kernal and got over 8000 with CF-Bench. I have tried the lagfree option and then the on demand one as well .. and still says its about where it was stock .. if not a little under. I have it set to 1.7 now .. 1.8 bootloops my phone.
[T-Mobile Samsung Galaxy S II SGH-T989] :
Performance is really based on real life performance. Not worthless numbers. Certain benchmark apps test standard performance. Not all optimization make benchmarks go up.

Some of them even make scores go down. Developers make kernels to boost real life performance not benchmark numbers.
[T-Mobile Samsung Galaxy S II SGH-T989] Strapt:
Well I get that but I don't understand why on another phone it would go up but mine goes down....and I haven't really noticed anything different with performance really
[T-Mobile Samsung Galaxy S II SGH-T989] :
I suppose for the same reasons some phones can handle the overclock and others cannot.
[T-Mobile Samsung Galaxy S II SGH-T989] :
Everyone phone performs different my mytouch 4g can get 4,000 in quadrant on a single core clocked at 1.8. Which is higher than my gs2. But my gs2 still performs better than it in every single task. I wouldn't worry about who can score higher or not. The best thing to do is not mess with any scripts and tweaks. When developers make a kernel or rom they give it the best optimization they can in the way they left it. Certain programs and task running also make the score go down as well. Usually when people run benchmark apps they clear the ram. Then run the program to get the best results.
[T-Mobile Samsung Galaxy S II SGH-T989] Wildchld:
You want to see what the kernel can do set your min to the same as your max then run test

[T-Mobile Samsung Galaxy S II SGH-T989] jjrumph:
I had the same problem. Other things would download but not the faux clock. Then read somewhere about issues with stock browser. So I tried xscope which I also use and it downloaded quickly.

This is what I read in another thread.

"The download problem has to do with android browser. Happens on all roms not the developers fault. You need to get an app called astro file manager. Go to preferences in the app and enable the browser to download anything regardless of files. Google really needs to fix the stock browser use any other browser opera or dolphin and it will download anything as well."

Hopefully it works for you as well.

Hi Roman, loving your kernel so far! As per the OP, I installed Faux Clock 0.8 to tune the CPU clock speeds. I set them to the same speeds I had using Synergy (max:1836, min: 384) and chose to set at boot. I left the governor at Ondemand and rebooted the phone.

It seems like, no matter how hard I try, I cannot get the OC settings to stick.. Is it possible to use any other CPU overclock program, such as SetCPU to manage speeds for this kernel?
