Nothing is wrong let it cool and then enter Synapse I think you were over the thermal throttle. While in a bench the first throttle is at 100c on CPU and again throttles if reaches 105c. If not in bench the throttle is 90 then 95c. Not to be confused with battery temp. It should run at the max you set in Synapse. But let it cool before entering so it doesn't think something set 1400mhz..

It goes from the max mhz you set to 1400mhz on the first throttle and if the second throttle temp is hit it will drop Max mhz to 1200mhz a15. Then again at that temp 1000mhz and finally again it will drop to 600mhz (1200mhz) a7 cores.

There is a power throttle you can't avoid if you reach it for a short time it will limit CPU to 600(1200mhz) a7 to keep from pulling more power than battery can supply.

You mention asking if there is no way to avoid the heat. Well in daily use heat should be fine but you can prevent much heat by just using a7 as your Max... It just as I mentioned places performance around the international unlocked galaxy S3 i9300...
[Galaxy S 4 General] AndreiLux:
The current 5420 devices don't use the CCI, even if they could.

I'll have to see what the 5260 brought with itself, but from screenshots it looked like a 3.4 kernel so who knows what they back-ported.

As for the next device, I'll have to see. I might be able to fix my situation with Google in the next few weeks. From the current rumors it seems the standard S5 will be crap and won't be touching that for sure. As for the premium, depends on what the 5430 will bring on 20nm.

Oh and about 4.4 on the i9500, it's still coming but it had some delays.
[Galaxy S 4 General] iede:
Never know this, so worst case our CPU will run at 1200 Mhz A7 on max temp :mad:. I'm wondering for the next 20nm process, should be more power efficient and colder.

Looking at the Note 3 Neo if it has HMP and performance much more better I think I will look at it :). Because S series lack of S-Pen. Because of this 5410 implementation maybe I will wait until samsung really develop truly 8 core with HMP then buy the new phone.

5430 for S5? it will be interesting with 20 nm.

Andrei, just a little bit off another topic. "Greyscale addend" in Screen tab increment is alway 0.39%? can we do it for 0.1 or 0.2% increment?
[Galaxy S 4 General] mw86:
Thanks Andrei was unsure :)

My opinion mirrors Andrei's... The S5 standard is same as a note 3 nothing life changing there. Especially since they are still 28nm chips. The 20nm will allow a bit more performance and a better power bracket than this 5410. I don't know if the premium price will be even worth the 5430.

I can't find info on the 5460 for awhile now. Is 14nm coming?
[Galaxy S 4 General] AndreiLux:
5260, there is no 5460. 14nm should come in a year.

0.39% is the smallest increment. 1 out of 255.
[Galaxy S 4 General] iede:
Because of each RGB component range is 0-255. And can we only adjust the Green channel? (R=0 G=3 (1.17%) B=0) I'm wondering because purple smearing, purple come from R+B. So my understanding the G channel is lagging while power-gating. Is it possible to do this? Thanks :)
[Galaxy S 4 General] mw86:
Did my homework now :) Yeah I hope the HMP is perfected, the 5260 in what seems to be one of many cpus in the Exynos 5000 series that are test cpus released to the public or atleast the 5410 was.. It would be great to see 8 cores independent to the OS in the 5430 and have them working together since this 5260 seems to be the 6core attempt at that. Samsung seems to use their many countless new device releases as testing on the public. Hopefully the jump from 28nm to 20nm is enough to drop the heat and power draw we see now on the high performance cores.

I read of cortex a53/57 last year does anyone know if 5430 may use these instead of the ARM cortex a7/15?
[Galaxy S 4 General] yahyoh:
Hmmm.... interesting : Exynos 5260 with HMP seems beat 5410 and S600 in most benchmarks its even close to s800 at way lower clock :D

Hi,

sorry for the stupid question but I have searched and I can't find it (might be it's too early in the morning for me and I'm a completely stupid right now).

Should a 'kernel cleaner' script be used prior Perseus flashing like it used to be in the S2?

Thanks.

[Galaxy S 4 General] farid993:
I have problem with wlan_rx wacklock and saw in this kernel he has fix like this:

Decrease RX wakelock time on WIFI driver

Reduced the wakelock time of RX packet in Wireless driver

Can we have fix/patch like these in Perseus?
[Galaxy S 4 General] iede:
I've never had this issue. Maybe something wrong with your network or access point.
[Galaxy S 4 General] farid993:
Before 4.3 I didn't have issue too. But i think if there was no such issue with other people then why "halaszk" tried to fix it twice?
[Galaxy S 4 General] iede:
Not sure about Note 3. But this kernel is for S4 and I think I never heard people complaining on this issue with S4 before
[Galaxy S 4 General] farid993:
I don't understand you! If Andrei use that fix, will you be angry or sad? I have a problem and a suggestion/request for it. I can not get it

Perseus for KitKat

Please! I Love this kernel, I've moved from 4.3 to 4.4, before I start Rooting&Booting is version 16.1 compatible, If Not any idea When? Many Thanks in advance!
[Galaxy S 4 General] mw86:
As for now guys the current kernels available are 4.3 tw or 4.4 aosp compatible... should be true for both alpha 17 and alpha 16.1
[Galaxy S 4 General] gp545:
There'll be 4.4.2 compatible kernel when Samsung releases latest Kernel Sources. :)
[Galaxy S 4 General] cmd512:
Yep, with so many features in Perseus I consider "essential," I'm not even bothering with 4.4.2 until Perseus kernel is available for it. :)
[Galaxy S 4 General] asia559571:
THANKS! mw89 & gp545 for the answer. Kind Regards

[Galaxy S 4 General] HassanM:
Can anyone plz post the download/changelog link for v17....

Thanks in advance. ..
[Galaxy S 4 General] iede:
Stable enough for me. I reduced all internal and memory voltage by -25 mV. No random reboot so far :)

And it's colder than before

"You can find the download link yourselves" means "Older kernel versions in case of regressions to be found here" ;)
[Galaxy S 4 General] mw86:
-25mv was working acceptable for me as well.
[Galaxy S 4 General] skivnit:
-12 mv gets me few reboots.. My chip sux
[Galaxy S 4 General] danveer:
Guys I know I am late to the party but I have recently installed perseus on my phone...:D

I just want to know any good auduo setrings to boost its output without loosing much quality..

Also do you guys get any random reboots?.. I get 2 to 3 every day:confused:
[Galaxy S 4 General] AndreiLux:
On 17 or 16.1?
[Galaxy S 4 General] iede:
Just now want to test even further. Decreased all internal & memory voltage by -37.5 mV and working good, no random reboot :)

Further I will try to decrease by -50 mV but I think that's my chip's limit
[Galaxy S 4 General] mw86:
Andrei if it helps additionally HassanM had boot issues on alpha 17. He said gets stripes accross screen and reboots. I often had seen that on gpu over clock crash in past. I mentioned try reboot a time or two to get Synapse to skip apply at boot and try to reset settings in synapse globally and apply but I don't think he retested that. I had same thing actually and its all I did and it got me running fine before on 17. I didnt test much with those volts changed but stock I ran a few bench on stock synapse settings for my cpu on 17 and it stayed stable no random reboot. Mine has one of the higher cpu bins so higher voltage table defaults... perhaps the better binned cpu on lower stock volt have issue on the new change. HassanM's table is definitely one step below mine for volts cpu gpu etc
[Galaxy S 4 General] cmd512:
My device won't even do -12.5mV on alpha17, screen turns bright cyan and system freezes.

Back to 16.1 for now, super stable.
[Galaxy S 4 General] iede:
Yes, actually it did happen to me when I flashed Perseus 17 first time. After that just reboot and now it's working all the time :).

I just realize now when I put -37.5 mV to all voltages then switch on Airplane mode. Switch off Airplane mode my phone can't get the signal back (need to power off). Then set back to -25 mV and problem solved.

Really curious what part of voltage that affects mobile signal reception? because so far with -37.5 mV that's the only issue for me.
[Galaxy S 4 General] mw86:
Interesting iede and yeah that's what I found second boot 17 ran fine consistently after
[Galaxy S 4 General] depooltrd:
When release the version of perseus for kitkat?
[Galaxy S 4 General] skivnit:
Yep first time booting got me cyan stripes and screen froze, I'm on - 12mv and i got 2 reboots already
[Galaxy S 4 General] AndreiLux:
Stripes are caused by undervoltage of internal. I don't have issues and even lowered it even more.

For those having reboots give me your ASV.
[Galaxy S 4 General] iede:
where can I find my CPU bind or ASV table?
[Galaxy S 4 General] AndreiLux:

[Galaxy S 4 General] farid993:
No i don't have this problem.

Guys If you use v17+ beside of Wanam Xposed you must uncheck "Enable Touchwiz DVFS".

Edit:

Ok. I am not so sure about that! because i was thinking because of that i can not reach to A15 freq ( over 1400. I overclock A7 to 1400) but now i do not know the reason because check or uncheck "Enable Touchwiz DVFS" isn't change that.

Sometimes it goes over 1400 and mostly it doesn't. Of course i did not change any voltages neither Cpu/Gpu nor internal.

I don't know what you're even talking about. The devfreq changes had nothing to do with the clusters. I also didn't see anything in the new sources touching the cpufreq drivers.

As for your deep sleep issue, I think it was again selinux/know/tima related. Not sure what version you're running there but I'm disabling all of that in the last release, and have good battery life.
[Galaxy S 4 General] dragon135:
Using v18 I have no deep sleep -.-.

Thanks. But i think something is wrong here because i'm not the only one have problem with A15.

I uninstall xposed completly so i think it is not wanam xposes fault.

Also i still don't get deep sleep ( v18 final) i wish you made one version without recent change of v17. At least we can sure are this change broke A15 or not. It's just a suggestion because i didn't have any problems with v16.

Ok i freeze synaps then reboot and now A15 work pefectly.

[Galaxy S 4 General] Jimmy34742:
In "Issues and Solutions," Andrei reports that the camera issue is "fixed as of alpha4," but I still have the camera bug. The link to the old camera fix quoted above is dead. When I manually copy the old camera files to /system/vendor/firmware as I was doing on the previous versions of Perseus, it no longer fixes the camera bug. Do people have a working camera with alpha4?

Nevermind, it's fixed. After installing Wanam 1.7, I installed alpha4 and immediately applied the old camera fix. That way, I trashed the ROM's camera files, and alpha4 no longer works with the old camera files on Wanam 1.7. After I realized I had to reinstall the ROM to get the camera files back, I did that and reinstalled alpha4. Then everything was OK.

I really like Wanam's Rom's and have tons of respect for him as a developer. But for some reason, stock MF8 (INU) performs a bit better than v1.7. Like cmd512, using stock MF8 + Pers V4 gives excellent deep sleep for me. On V1.7 I was getting odd wakelocks with BBS.
