Feedback will be appreciated. ...
[Galaxy S 4 General] cmd512:
Everything is scaling fine, you just need to make sure you turn off DVFS in Wanam Xposed as that will fight the custom scaling in Perseus. I am getting odd freeze/reboots sometimes immediately after a boot, then it's stable until I manually boot it again. Could be because I flashed from 4.3 directly, but overall, it's working very well and battery life is looking good.
[Galaxy S 4 General] AndreiLux:
BTW I'm running odex since the beginning and never had issues. So so much for that theory.
[Galaxy S 4 General] cmd512:
Spoke too soon, phone is having deep sleep issues with this ROM and Perseus as well
[Galaxy S 4 General] zetlaw:
Im trying for the last 2 weeks to figure out whats couasing this issue. I cannot find it. But what i could find is that after few reboot you will get a system that works with a15 and deep sleep. But when you reboot again it will comw back stuck at a7 and no deep sleep.
[Galaxy S 4 General] cmd512:
l2_hsic wakelock just goes crazy when I shut off the screen and is what's keeping it awake and preventing deep sleep, has to be fastdormancy related as there is an lcdon vs lcdoff setting under nwkinfo. Just changed all values to 0 for my network ID, and phone is deep sleeping after reboot with l2_hsic behaving now, will keep monitoring.
[Galaxy S 4 General] zetlaw:
What about a15 cores ?
[Galaxy S 4 General] cmd512:
Working fine

UPDATE 1:

At some point after the screenshot was taken above, the phone again stopped going into deep sleep and also noticed it was no longer scaling to the A15 cores. In the hunt for this elusive bug, sent Kernel, Modem, and logcat over to Andrei, already got the following feedback:

"Bravo as you're the first person in 3 months with the apparently very rare gift of being able to provide logs.

The mobiCore driver is acting stupid and ends up in a error loop. The mobiCore driver is the secure OS layer which resides in the TrustZone partition among others and handles stuff like secure storage an DRM shenanigans. The issue might be highly dependent on the tz.img and your current bootloader, but there might as well be magical unicorns in there and nobody would know, so nothing is certain.

I suggest verifying that your build.prop of the ROM has secure storage, selinux and TIMA disabled. The kernel should change these, but I see SELinux Might maybe as well look into a way to disable the mobiCore daemon service. I'll try to see what happens if I disable the kernel driver if the phone will even properly work."

Will keep everyone posted.

UPDATE 2:

Just checked my build.prop, tima and selinux are all set to 0. However, ro.securestorage.support was set to true, I've set that to false to test. After 10 minutes, still deep sleeping and scaling up to A15 fine.
[Galaxy S 4 General] zetlaw:
Try rebooting and see if it still works.

i've notice sometimes everything working perfectly until i reboot.
[Galaxy S 4 General] cmd512:
Nope, it stops scaling to A15 and going to deep sleep even if it worked initially after a boot. Point is, it's not a matter of if but rather when, it WILL eventually fail.

But after setting secure storage to false, has been working perfectly. Will continue to monitor.
[Galaxy S 4 General] zetlaw:
just updated my own cooked 4.3 rom to own cooked 4.4 rom changed ro.securestorage=false and it works.

AMAZING.

thanks [MENTION=1984051]cmd512[/MENTION] and ofcourse the great of all [MENTION=4167023]AndreiLux[/MENTION]
[Galaxy S 4 General] cmd512:
I didn't do anything except grab some logs, credit goes to Andrei.

AGAIN PROVING people: Devs can't address / fix stuff if you don't provide logs!!
[Galaxy S 4 General] zetlaw:
What kind of log did you sent ? Because i checked catlog of boot and when a15 start to stuck. I didnt see anything suspicios.
[Galaxy S 4 General] cmd512:
Not knowing what was causing the l2_hsic, I grabbed and sent all 3 logs: Kernel, modem, and logcat. The Mobicore finding wasn't in the logcat but rather the kernel log I believe.
[Galaxy S 4 General] zetlaw:
Ohh. -:) i didnt know kernel and modem logs were existed -:)

S4 is my first android phone.
[Galaxy S 4 General] cmd512:
Grab the app Syslog from the Play Store, will grab all 3 and email or upload to cloud... super easy to use.
[Galaxy S 4 General] AndreiLux:
The error was plastered all over your logcat.

Anyway if this does indeed fix most people's issues, it's fair to call you all idiots for not being capable of posting logs for over 3 months.
[Galaxy S 4 General] cmd512:
Got it, don't have my logs in front of me now so wasn't sure. But yeah, I just upgraded to KK yesterday, grabbed logs today, and it's resolved... sad.
[Galaxy S 4 General] wyumhk:
I also had the "l2_hisc wakelocks and"no deep sleep" issue, I just upgraded my modem to XXUFNC1 (XXUEMK8 before) yesterday.

I am using RomSwitcher, dual booting Omega V20 and CM11. I have rebooted my phone and switched the roms many times, it "seems" the new modem has fixed the issue.
[Galaxy S 4 General] cmd512:
MK8 isn't even a KK modem, our issue has nothing to do with that as we've been using KK modems. The build.prop fix completely eliminated the issue for me, phone is still functioning perfectly after 8 hours.
[Galaxy S 4 General] zetlaw:
Working great in here also after changed the securestorage. Maybe andrei can solve our last bug that is wifi hot spot.
[Galaxy S 4 General] cmd512:
I'll try Wi-Fi hotspot later and if it doesn't work, I'll grab logs.
[Galaxy S 4 General] cmd512:
So, confirmed that when I turn on Wifi Hotspot Tethering, no wireless devices can find the AP. Is this what you guys are seeing as well?
[Galaxy S 4 General] Anakha56:
Wow!

Thank you for providing logs to Andrei for getting this fixed and for teaching me that besides logcat there are two other log files to give. I am loving the wakelocks for l2_hsic dropping thanks to this fix. :) *fingers crossed it stays put*
[Galaxy S 4 General] makaroonzkr:
my phone freezes then reboots after installing perseus on Thunder Universe 6 :crying:
[Galaxy S 4 General] KnifeHead:
Naaah... for me, they who report to you that bug is exist is not an idiot. They are users that want your kernel more better and better.

Why this happen for 3 mont? Becoz you just underestimate them. You are a big dev and them just user.

You will not call them "idiot" if you can debug yourself.

But, you just ignored them, you said "mine works perfectly", just becoz you use your tweaked rom made by yourself so you didnt notice the bug.

You will defend yourself by saying "I need a log", naahh...you can did that yourself by change your perpective to an "user", by try flashing stock rom or other cusrom and see if that reported bug exist, debug it, fix it, done.

So what about wifi tether? Wait for other user log again?

Hahahahaha :D
[Galaxy S 4 General] NEOAethyr:
I asked before about logs and there was no answer.

I even tried to figure it how to log it out on my own but the kernel stops logging after a point when it shuts down and doesn't show the charging crash.

Hell I think I even posted that log pages back...
[Galaxy S 4 General] AndreiLux:
I have absolutely no responsibilitiy to go to flash ROMs around and hunt for something that I've proven that is not directly related to the kernel. SecureStorage should be disabled because it will cause problems with Wi-Fi not remembering their passwords. I've told enough times that I can't reproduce it and that you're responsible for providing me information because I won't search for a needle in a haystack that may not even exist.

Stupid posts like these is why the "development" thread got closed and why I didn't bother to reopen it. Except for cmd512 (who managed to identify this 3 month issue in a 1 minute act) and some other exceptions I don't remember the last time any of you actually contributed anything at all since I bought this device over a year ago. And no NEO, you did not post any worthwhile log.

I'm tired of this sense of entitlement and why I don't care to invest more of my time and energy into something I get nothing back but annoyances. The kernel runs perfectly for me and I already brought up all essential stuff long long time ago. I'm having more enjoyment working on Synapse in my free time since other developers are actually involved in it, and did some really great stuff with it on the Nexus 4 and 7.

I'm also busy with other stuff, so if you're not willing to put the absolute minimum in effort into an issue then don't expect anything in return. You should be in fact ashamed of your ignorance and unwillingness to contribute.

There's a bunch of other devs on this device and others who don't even publish their work due to the frustration that comes with having to deal with such a community. If it comes to it, I have no issue with doing the same.
[Galaxy S 4 General] Paolonicus:
Guys, have some respect for him. If most of us were so smart, we could have created and keep on improving the Kernel ourselves. Creating and updating this takes knowledge and time, and for us it is something we don't have on a daily basis. Give credits to him coz' he deserves it, and don't drive him crazy or we'll be left hanging.
[Galaxy S 4 General] NEOAethyr:
I don't have any "sense of entitlement", I'm just asking for help lol.

If you could tell me what logs I should be posting I would do so in a heartbeat, well maybe, I get busy too :P.

The only prob I have is the darned sleep of death prob...

And it only effects custom kernels.

Like I said million times, I can't even use a custom kernel on an older rom "anymore".

If you really don't care then I'll be off doing my own thing then, I gotta eventually compile my own anyways.

I just really don't wanna do it right now, I got so much on my plate as it is.

Anyways thanks for the older ver's that actually worked on 4.3 and 4.2.2 (well I wouldn't count the 4.2.2 ones as actually working 100% though).

But still, thanks :).

sigh

Well anyways I'm gonna at least give these build.prob tweaks a try to see if that fixes my prob too :\.

Edit:

well that didn't work, had the secure storage enabled, disabled it but nottas.
[Galaxy S 4 General] KnifeHead:
Thank you for your hard work :)
[Galaxy S 4 General] AndreiLux:
If I would know what logs I need to figure out an unidentified issue, then I wouldn't need it in the first place. Cmd512 just sent me everything, kernel/modem/logcat and I just looked through them and it was resolved 10 minutes later.

As for your sleep of death issue, I already removed the devfreq controls that caused instabilities for most users.

In the last few weeks I also had my phone just shut off and after several days of debugging, it ended up simply being that my Zerolemon battery was at fault because it didn't make physical contact anymore or something, and put my stock one back and haven't had issues since.

Imagine you have something even remotely to that, how the hell am I supposed to even fathom it would be the cause of an issue?

A little more pro-active thinking and self-action is all that's needed...
[Galaxy S 4 General] NEOAethyr:
Ah lol, I was about to say, why not state what sort of logs are needed on the front page for bug reports... :)

I use the stock battery, never had a prob with it actually (Cousin is looking into 'other types of batts).

I have been looking for solutions on my own, just not much lol.

I did read something a while back about logging the kernel via adb, but I need root in that, not sudo/su.

I tried to mod your kernel's default settings for both 4.3 and 4.4.2 (v19 supported both apparently).

But the prog I used to do that was flaky and caused a no boot, had to recover (and yeah I know about the diff 0x0a0d, 0x0 whatever it was... cr/lf text stuff).

I'de need a custom one time kernel for that, and that's if it would do any good, I really don't know for sure if there's going to be any logs of use yet.

I figure that's something you probably wouldn't do anyways, you would of already done so probably.

Well I guess, can I req a test ver with adb secure whatever it was disabled so I can log this sucker remotely?

I've been working my butt off on other things too, I haven't gotten my bios bugs reported yet for my new mobo (r4be), it's been 7 months lol.

I need to order some smd resistors, and pop one off my 2nd gpu, solder one onto my 1st, finish my unix os thing.

Capture my tapes..., capture my recently deceased great uncle adventures in vietnam, blah blah blah lol.

Oh there is something I can probably recommend though.

Deadline is probably better then noop...

The benches online seem to indicate such anyways.

Alot of peeps like bfq though, not for me though...
[Galaxy S 4 General] cmd512:
The onus has always been on

US

as users to not just report bugs, we have to support all bugs with adequate logs. You just coming in here complaining about issues doesn't help, it doesn't matter how legitimate you think your issue is.

Keep in mind, the devs are doing all of this development in their own spare time. If your expectation is for them to also go bug hunting for every little damn thing that gets reported as well, then you really have your head screwed on backwards.

(I get that some of you don't know how to grab existing logs, especial kernel and modem logs. I didn't know either, until I searched on Google / Play Store and found the appropriate app. Frankly, if I can do it, so can you. A little effort goes a long way.)

I've already grabbed all 3 logs of the Wifi HotSpot Tether issue: I can enable it fine on my device, but no wireless devices can see it when scanning for APs. Andrei, let me know if I need to grab any other info for you regarding those logs.
[Galaxy S 4 General] Silver Wx:
Good kernel for me !
[Galaxy S 4 General] zetlaw:
Hi [MENTION=4167023]AndreiLux[/MENTION] i found another bug related to tethering.

this bug occours when using USB tether, the CPU goes up to max frequency and never goes down until i cancel the usb tether.

Logs

look at the end of the logs. i generated the problem and then took the logs.

i hope it will help you solve the WIFI tether issue.
[Galaxy S 4 General] ice.modding:
warned that the idea of ​​this when it happens is that they use up the syslog and logcat to help the dev to fix the bugs that are :)
[Galaxy S 4 General] davtse:
I don't think you have EVER developed a kernel or been part of a beta team, so you don't know how difficult it is to do anything without logs provided from user end. As part of a beta team for a kernel, every time someone claims/states there is a bug, we have to download the ROM and install it to try and reproduce the bug. We have to do a clean install to eliminate any errors from user end. And then we have to try and do any and every thing to try and reproduce the bug, all because some user states "there is a bug" and provides no other useful information. All this takes HOURS on our end. This is not a job. It's a hobby(if you could call it that),and we are provided with no incentive or remuneration to do so, except that we help make something good, even better. If you have no idea how disruptive this is to the personal life of the people who do this, let alone the developer, you have ABSOLUTELY no right to make the comment you just made.
[Galaxy S 4 General] DarkMD:
One noob question.

I have raised my min freq to get only the a15 cores running. But is not working =(

Update: i change the secured storage to false in build.prop and nlw im scaling a15 xD. Sorry for being so noob and sorry for my bad english
[Galaxy S 4 General] Jacynth:
is this kernel unstable? when i use this kernel my phone get free and randomly boots sometimes. but i like your kernel :victory: btw im using UnchartedRom
[Galaxy S 4 General] ice.modding:
you can install syslog (PlayStore) to help the dev to fix the bugs that are :D
[Galaxy S 4 General] NZnewbie:
Yes i think its stable. No probs apart from wifi tether issue but usb wifi works so its not really a big deal.

Best around for the I9500 i think.
[Galaxy S 4 General] cmd512:
Read the last two pages, the fix has already been discussed to death and confirmed. I'm running the exact configuration you're asking about with zero problems.
[Galaxy S 4 General] Jacynth:
thanks guys :highfive:

last question do i need to wide cache and dalvik cache ?
[Galaxy S 4 General] ice.modding:
+1

not necessarily
[Galaxy S 4 General] lukair1983:
Hey guys

Does any of you have, or had, some ocasional sound disturbances, while listening to music with screen off? Using Andrei's latest kernel on kitkat, gives me on some ocasions some stuttering or very short sound glitches and I was wondering if any of you had same expieriences?
[Galaxy S 4 General] cmd512:
None for me, just sometimes the sound disappears after using headphone and unplugging it.
[Galaxy S 4 General] adibhaniff:
Did you undervolt your cpu/gpu?
[Galaxy S 4 General] cmd512:
Of course, but that's not the issue, no problems otherwise and had the same settings in 4.2.2 without issues. But again, it's random, and a quick reboot fixes it, so not a big deal.

This phone's been weird with audio disappearing anyway, did that on stock kernel for many of us as well.
[Galaxy S 4 General] adibhaniff:
Can u share your UV settings for cpu and gpu? Did u undervolt memory interface also? I have a lot of questions to ask you. I'm new to undervolting with perseus. I do know if we UV the cpu too low the device will crash coz of unstability. But what about the gpu? What sign of gpu unstability can i notice if i UV the gpu too low?

My current setting:

Little cores -25mV all steps

Big cores -75mV all steps

GPU -50mV all steps

I did not overclock the cpu/gpu. A7 1200mHz, A15 1600mHz and GPU 480mHz. Also if i use 532mHz gpu for daily driver, what are the consequences? Sorry if i ask too much, i just need to make something clear.1
[Galaxy S 4 General] cmd512:
Every single device is different, there is no "magic formula." Just take the time to make adjustments, and if things are unstable / crash, bump up the voltages.

Only advice I can give you is: Do one adjustment at a time and thoroughly test it out before adjusting another. That's the only way you can isolate what is causing the instability.
[Galaxy S 4 General] adibhaniff:
Which software that i can use to stress my cpu or gpu to determine stability? By one adjustment at a time, do u mean check everything for each stepping? And how can i do that?
[Galaxy S 4 General] cmd512:
Search on Google Play, there are a ton of options...
[Galaxy S 4 General] farid993:
My Little cores is -50mV and it is stable.
[Galaxy S 4 General] MAX 404:
Thanks a lot for the great Job!!

Dealing with users is an ungrateful experience .....there are more regrets than rejoice but believe me your efforts are appreciated by many of us here.

THANK YOU !!!

When I flash this kernel, my phone is always unable to charge its connected but it doesnt charge even when showing the animation I have tried wipid clearing both dalvick and nornal cache but no luck on stock kernel problem does not happen.

Any ideas?
[Galaxy S 4 General] NZnewbie:
Hi, You could try opening synapse app and go to the battery tab, then check the readings under battery power at the top of the page.. you can from this tab see the input, average and now. This will help you work out if your charger/usb lead has dropped the soap(failed) :D.

Hope this helps.

Hi, there is any version of perseus to run on cm11 4.4.3 ?

if i flash the 19.1 when it boot it gives me com.android.phone has stopped unexpectedly and there is no way that goes away... so maybe im doing something wrong..

i9500

cm11 20140612-unofficial-i9500

i've tried to wipe cache, dalvik, data and still the same..

any clue someone?

Thanks in advance!
[Galaxy S 4 General] NZnewbie:
Hi,

You could try and clear the cache in application manager- com.android.phone and maybe that will clear the fc. Maybe the same process with contacts in application manager as well if the first doesnt help. After that.. Full wipe and retry.

Good luck.
[Galaxy S 4 General] ktouy:
Hi, i've already tried to clear cache and so on from those apps, but the thing its that it doesnt allow me to move across the sign wont go away no matter if i hit ok, and i also already do a full wipe cause i came from a tw rom. Also tried to clear cache and data from apps and reboot to flash but it isnt working.. I will flash the lastest nightly today and i will try again..

Thanks!
[Galaxy S 4 General] ice.modding:

[Galaxy S 4 General] zozoz13:
why there was a slight delay when I open recent apps. is there any solution?

Stock support?

Hi, i know this may be a real noob question but here goes..I have an i9500 international variant and it is rooted on stock 4.4.2, my question is can the perseus kernel be flashed on my device on stock firmware?

Not a noob question but rather a lazy ass one!

How about reading a few posts or searching the thread?
[Galaxy S 4 General] HassanM:
Yes!

[Galaxy S 4 General] HassanM:
Friends,

Im on Omega Rom v22 (4.4.2) w/ the latest Perseus 19.1.... Its an amazing combination!!!! The phone is running perfectly fine/smooth with no problems whatsoever.....

Somehow today I just realized that in Synapse (the latest version), the "Head Phone Amplification" under the Audio Section, doesnt seem to work. However, the equalizer settings for the speaker/earphones is working fine... I must mention here that I have modified some values in the default_gain.config....

Can anyone plz shed some light on it??? Could this be somehow related to default_gain.config modification or is there something else to it??

Thanks in advance....
