[Discussion][Perseus Kernel][GT-I9500] - Galaxy S 4 General

To keep Andrei from going crazy with non-development related questions, I've opened the following thread. That way we keep the development thread for development topics and this for general discussion.

Good deal.
First feature request: Fading in/out LEDs! I've pinged the dev for LightFlow, and while he can implement it on a software level, it would be supremely inefficient and probably drain the battery like crazy.

Actually that's something which belongs in the dev thread. If anything you can just post on the issue tracker on Github, I've grown vary of XDA.
There's a new TI LED controller so I can't port the old Philips controls from the old phones. I'll rewrite it eventually but I got other things to do now.

Done, posted on Github!

just got my s4 one day ago. rooted immediately, flashed omega7.0 and the latest perseus. did not touch anything on the u/v in stweak. no o/c as well. but the antutu score is so low 21000+, i thought it at least supposed to be 27000+?
i tried adam kernel, had the same result. is that normal? did i miss anything?

thanks for you response. as i mentioned i got it only one day, without touching anything on u/v & o/c. i guess this is considered lower score than the stock one? i merely care about bench mark, i just want to know is this normal? or i need few days to let it settle down? fyi, i tried more than 10 times and it only score between 20k-21k. perhaps you can be kind enough to give me some idea rather than congrats me.

It is normal for benchmark to be lower than on stock kernel all devices differ. Following the development of this kernel it has been stated that the kernel is not intended for high benchmarks but more for overall stability, smoothness and better battery life.
Benchmarks is just a number and a high benchmark does not always mean your phone is smooth and performs very well under normal user conditions.
Hope this answers your question and should I be mistaken about anything anyone welcome to rectify me on those points.

i never meant that perseus is running low on benchmark, in fact, it's the highest between chainfire's cfroot, wanam's adam. i tried all these 3 kernel, all score only between 19k-21k. i just wonder if i have accidentally limited my cpu speed? i will do a factory reset and re-test it.
again, i dont or merely care about benchmark, i just care if my s4 is running normally.

I have kanged Andrei's response with respect to benchmarks.

Benchmark freaks can enable the boost mode manually: /sys/class/thermal/thermal_zone0/boost_mode .
The first throttling speed is 1400MHz and that's why it spends a lot of time there during benchmarking.
Effectively, overclocking on this device makes very little sense unless you can achieve more thermal headroom with undervolting. I personally couldn't get over 1.8GHz on random loads, and couldn't get over 1.7GHz on benchmarking (Antutu 31300).
Nevertheless, the option is there for people who want to stick their phones into their freezers. For everybody else, stop being concerned about numbers.
This seems to affect only a rare number of people and I still don't know the cause. Just cycle the screen once and be done with it.

[KERNEL][GPL][ACS]Xtreme Kernel v1.2.0-Lucy-1.3GHz OC,Battery,Tweaked Voodoo(options)

ANDROID CREATIVE SYNDICATE​presents​XTREME KERNEL V1.2.0​
First of all, I want to put my thank yous up here at the top, so, here they are:
-geniusdog254 - My primary teammate, been helping me every step of way.
-nullghost - One really cool dude. Always on when I ask for help. Git would still be a scary thing if not for him.
-rjmjr69 - Funny, funny dude. Keeps me motivated to keep going
-The Voodoo Team - Your work is awesome!
-My beta testers - You were/are all great. Thanks for helping me with this!
-All the devs across the board - Seriously, you're all a bunch of absolutely awesome people.
-Anyone I forgot - You're all great!
Now, here we go:
THE STANDARD DISCLAIMER
I, DevinXtreme, AM NOT responsible for what happens to your phone, your cat, your house, or anything relating to you! If your phone bricks, OH WELL. Have a nice day.
This kernel has a MixUp kernel base. DI18, blah blah. I deviated once Interactive got working. I also removed the Voodoo color modification. So, there's that.
It is built and designed for Syndicate ROM, which will be out later tonight. Sickest ROM you've ever seen. The version released with the ROM is slightly different, but only for fun's sake
Changelog:
v1.2.0
-Removed the 1.6GHz step. The time machine is gone. Plus, was causing more problems than it was helping.
-Added 1.3GHz step courtesy Herver
-Switched from MPLL to APLL. Smoothness and speed increase. Thanks to nullghost for help on this.
-Added Voodoo color mod, tweaked version, courtesy Herver. I will be maintaining a no-voodoo version. I just haven't yet.
-Tweaked the light sensor, adding a new step and made it not jump to the brightest setting as much. Should save battery and transition smoother. Also pols a little more often.
-Tweaked scaling rules for 1.3GHz. Should scale there less, thus saving battery.
ADDITION: The file ending in 'nv.zip' is a no-voodoo version. The file ending in 'ov.zip' is the version for the original voodoo mod, not the tweaked one.
v1.0.1
-Fixed scaling. Linpack scores and tests work fine now.
-Disabled Carrier IQ in init.rc. Carrier IQ is essentially Sprint spyware. Kernel devs: This is really easy to do. Just comment out the iqmsd lines at the end.
v1.0
-Overclock to 1.6GHz!! Requires SetCPU which is, for some reason, defaulting to performance. Make sure you change it to conservative.
-Default governor without SetCPU is conservative with 200MHz-1GHz steps.
-Removed Voodoo
-Framerate unlocked (78-80fps)
-Built for ROMs with a custom boot. Makes stock boot look like garbage. We're working (still) to fix this.
-Undervolted
KNOWN BUGS:
-In spare parts, if you set the WiFi policy to never sleep, it still sleeps with the screen off. -skandranon314
-Some weird vibration thing going on when 1.6GHz is hit.
NOTES:
Linpack is being strange with this. I'm getting between 9.2 and 9.8 with some REALLY strange numbers. I'll have this fixed this weekend.
SetCPU sets the default governor to performance. If you use it, be sure to change it immediately for battery life.
FOR 1.2
-I recommend 200MHz-1200MHz. Some phones can't reach 1.3GHz safely.
-200MHz - 800/1000MHz is a great setting for battery and you should still have a very smooth experience.
For those who care, I get 1135+ in quadrant.
You can read my source here.
Thanks, guys. I hope you enjoy!
How stable is this??
When is the rom out?

1.6 GHz???????
That's awesome, though I don't think I'll crank it that high.
Is there any advantage to this vs MixUp running at 1.0 Ghz?

Ok, good. I was worried for a sec
So would you recommend flashing the new one when it's up since you're tweaking it?
Hmm.. something's not right here. I just got 22 fps in Neocore with the removed kernel. What could I be doing wrong?
Edit: Switching from performance to conservative upped my results to 62 fps which is quite respectable.

Yeah, it'll be a good idea.
what kind of voltage are you giving it to get 1.6 stable? based on what im reading, anything above 1.3/1.4 is pretty much unachievable on these devices and is not really the speed that the device is running thus the unscaled rise in benchmark scores. iv been following hero_over and he couldnt get a stable 1.4 OC although he did get 1.3ghz on stock volts stable..which keeps me wondering if we really can hit 1.6 stable

All of it is on my git. I release my source, as devs should with GPL. The problem is that the fsb isn't scaled properly, affecting the floating point processor, causing low Linpack scores. I'll have it worked out this weekend,

[REQUEST] Kernel W/CPU & GPU OC

I was browsing the Optimas 2x forum today and ran into an awesome kernel with GPU overclock. which sounds pretty cool to me. also the dev mentioned something about overclocking "system bus" which improvers memory/2D/3D/etc. i think someone in this forum should take a look into this KERNEL and try letting us taste some of this goodness.

G2X
CPU overclock is something that makes sense for us right now but what would a GPU overclock get us? To me thats just something that will lower the life of our phone with no real reward until games come out that our phone can't run. Right now our phone can run pretty much all games at full speed.
gpu overclocking would be sweet... now my question would be has anyone tried to load Optimas 2x kernel/software on the g2x since they are pretty much the same hardware(in theory you would think it would work)... i might even try to load this kernel onto my phone when i get home from work so if i mess anything up ill have my gear to fix it

I remember reading a while ago that GPU/System bus overclocking was attempted by some kernel dev, then later on, the dev realized through extensive testing that GPU and system bus clocks were locked, the changes to the kernel source had no effect (hardwired). Now this was a few months ago when I was reading up on Tegra kernel development before I got my G2x. Now all these could have been obsolete, and maybe now someone has found a way to do the above via kernel source updates.
Another issue that most people don't mention here and many people have been guilty of, is the GPL issue. The guy who supposedly did this overclocking has not published his kernel source code anywhere (GPL/XDA rules issues), so no one can examine what he did and prove that it worked....

Someone in another thread tried this and it messed up their baseband. A restore doesn't fix it apparently.
Big rush dog, the tiamat kernel guru and Guy getting engadet headlines for oc the xoom to 1.7 ghz has gpu oc in his kernels. I will be honest though, I can't tell the difference except maybe video streaming works a little smoother. I personally don't think it is worth the devs time...
Sent from my LG-P999 using XDA App
Howdy! I'm the developer of that kernel
To be honest the GPU overclocks aren't all that beneficial. There is a little bit of a speed bump (I managed to get the highest score on nenamark2 for example). But the difference is was 27fps vs 32fps. If someone is interested in incorporating that into the g2x I'll be happy to show them the changes I've made. I haven't released the source because I'm lazy but there isn't too much to it.
Actually, if you look at the voltKernel sources for the O2X you'll see the same changes there.

Yes, superficial benchmarks like quadrant can be pushed to 5400 only with max cpu oc.
However, did you notice how 1.2 thru 1.5 gets you the same fps with no added benefit than more heat created?
Pushing other things other than cpu should let us remove bottlenecks and not tighten them up.
If you want your G2x to life 20yrs, 1.5ghz is not the way to go.
I have no kernel ready for release, to notice changes, I stuck to 1.5ghz, but the final result will be more likely 1.2 or 1.3ghz.
Maybe with a "don't hold my hand, give me freedom or give me death" DBU version at 1.5Ghz later.
I'm not shy to increase vcore on a SoC. But unlike the Nexus S, this thing gets HOT, fast.
Avetny pointed out that thread, I'll see if fallout hit something I have missed so far.
The clocks get compared to chip defaults in many places, choosing the smaller of the two, so it's just tedious replacing them with sane defaults, unless I stick to my current approach of offsets instead of absolutes.
We'll see.
That's also the reason I don't update my kernel often. Right now commits in cm git are only preparatory, config changes that made things smoother I already used.
I'll release something if they finish their version of BLN.
Or if I'm happy with gpu/bus/ram oc/tweaks.
not going to make people flash a kernel for no reason. As jlevy can attest, kernel not following cm git, not even based on it can work very well.
Not having latest cm commit on kernels that take another approach is not always useful.
Especially if we track regressions that cm devs back out later, that's all this gains.
So yes, there will be a gpu oc, when it's ready.
Great!
@ fallout0 thank you i hope that you can help out one of our devs on this.

You should talk to Fallout0 he seems like he got past the system bus/GPU locked issue. both of you can maybe learn something new from each other. & it would be awesome if the both of you can work on a kernel together.
Wouldn't a higher clocked G2x cause more heat? Heat being the reason this things reboots so often? Maybe a slower G2x is the way to go.
Would overclocking the gpu help run nds4droid any better? What else would ocing the gpu do? Everything seems to be very fast as it is lol

Pushing cpu more I don't see useful other than keep up with your buddy's Nexus S' quadrant scores and make sure your hands stay warm in a cold Chicago winter.
I build kernels usually when things stutter or otherwise annoy me. The pushing the OC usually comes by request of those who just want more more more.
I do like to remove bottle necks.
The hardwired clocks. Well the.cpu ones are hardwired too.
The gpu/bus oc works, until boost and throttling kick in, where again values are compared to hardwired values. using offsets after the comparison would be the way around without killing boosting and throttling.
Guess main thing that stopped me is the heat at 1.5ghz, and the frowns over 1.2ghz and 1.3ghz kernels, without further "what else is in there"
Still hoping fallout can share what he/she has, it'll help making this a reality, sooner.
It's tedious. Most of all.

Overclocking - pros & cons?

Yes, I FINALLY did it!!! I overclocked my G2X. I would appreciate if anyone could share their experiences with o.c. pros and cons... Should I retreat or stay where I am? Please some feed back!
Over 1300 seems to cause trouble on mine.
i dont think oc'ing is really that necessary with a phone this fast but if u must i wouldn't go above 1.3 (just seems unstable above that). I think the "Pros" come from being able to underclock. Setting up profiles for uc'ing when screen is off or as battery level drops etc really prolongs the life of the battery (at least in my case)
On my OG droid that came limited at 550 mhz, ya, oc'ing was def necessary but I cant really think of any "Pros" for oc'ing this phone.
each phone is different though so play around and you'll find a combination that works great for your phone, good luck
Well... you can get some serious bench scores... This thing rocks the Mandelbrot multithread test in smartbench 2011 at 1.5 ghz. Other than that it helps with games.

What about the CPU not having enough cooling and frying the CPU over time. I presume its just like Desktop overclocking but without all the extra cooling you can add to make it safe for the hardware.

But what i really want to know is if oc could damage the phone. After all if there is that danger it's noy worth it...
In all honesty I used to be really into benchmark scores and OCing the heck out of my phone and under volting it in the process but that led to many battery pulls ect. What I've noticed is just keep it at stock and mild uving seems to be the best for me its stable decently fast just 2 cents though
Overclocking a cpu is the same as on a pc, only a bit more dangerous on a phone. (This phone already has overheating problems running at stock speeds ) On a computer, people pay a premium for parts that are easily overclocked, and have either very good fans/heatsinks or a liquid cooling rig.
Overclocking is dangerous, especially because not all chips are going to be made equal, even if they come off the same production line. These chips are designed to run at a certain voltage, and certain clock speed. As far as real world use, (NOT benchmarks. Sure, they look pretty and all, but benchmarks are never very accurate.)
Sure, you might get 2-3 more fps on your games, but is that worth the risk of shortening the life of your chip/phone?
(And just so you know, I've been building/overclocking pc's for years, but I also understand what you need to do to keep it stable, and it's *all about cooling*.)
If you're not convinced, try this. Don't overclock your phone, and use it for a few days. Tell me honestly that you really notice a real-usable difference with the chip overclocked or not. (Games set aside, but like I said, getting a couple extra fps on a game to me isn't worth the risk without a proper cooling setup)
For those of you that really don't understand what you're doing to your chips when you overclock, I'd suggest doing some reading about it. A good place to start would be here: http://en.wikipedia.org/wiki/Overclocking
So you think using fauxs kernel is not safe or reduces the life of the chip? I just flashed it and didnt oc or uv further then fauxs default settings...

I'm not saying it's for sure, I'm saying there's a chance.
Plus keep in mind that these kernels have other really nice additions besides overclocking and undervolting. I'm using faux's stock voltage kernel ext4, and leaving it at stock settings, and it really works great.
I just posted this up because I see a lot of people more interested in quadrant scores (which to me are pretty useless) than stability of their phones. If you do overclock, and it works for you, more power to you. I just want to inform people. I'd HIGHLY suggest if you aren't sure, read that wiki article, it's a great place to start. (not all information is there, but it gives a very good general idea on how and what overclocking is.)
Thanks! i always like reading knowledgeable and informative posts!

OK, you definitely convinced me.... I have also faux (let me tell you exactly - Kernel Version 2.6.32.9 FR Faux 123-v0.03) on EagleBlood 1.05. Could you please tell me what I need to do set up in order to be safe? Thanks!
I'd just go to faux's thread in the development section (his froyo thread, not the cm7 one, since you're using eagleblood), and download his stock voltage kernel. (It's in the first post.) He's on .04 now, by the way.
Then reboot into recovery, and flash the file you downloaded. It'll overwrite your current kernel and modules with the new one, then reboot.

I could not find this thread under G2X Android Development Section... I found threads Kernel Trinity, Kernel CM7, Kernel LGE Stock Froyo, Kernel Morphine... Which one is it...? Please do have some patience, at least I learn fast!

You passed right by it. LGE stock froyo. (That doesn't mean it's a stock froyo rom, it means it's *based* on one )
http://forum.xda-developers.com/showthread.php?t=1102720
Choose the stock voltage one. (ext3 or 4, depending on your preference.)

And a lot of times the kernel will be credited to the developer. So if you see "faux's kernel" people are referring to kernels by faux123. Trinity kernels were developed by morfic. If you are having a hard time finding a specific one, look at the top left to see who started the thread and sometimes that will help find it. Does that make sense? I had to pull an overnight at work so I am a little loopy....

[Q] Question Regarding ROM "Ultimate ICS V2"

Hey there! OK before I start, please understand that I am WELL AWARE that quadrant scores don't necessarily mean a whole lot when it comes to the performance of a rom. I get that. However I do have one question regarding this one. I notice in the ...what, 3rd video test? I dunno, the one with the moon orbiting the planet. It won't go over 10FPS. This to me is not right considering how great it performs on all the other tests and also considering that my old Optimus One usually gets 55-65FPS on that exact test. I tried with the kernel that comes with the rom and also with GlaDOS 2.5 kernel, both at 1GHz and 1.2GHz and the results are exactly the same. Is this a bug? Is there a fix, or a work around to improve this? I see the nexus S scoring 2400-2700 on quadrant and with this 10FPS on that test I am still scoring 2100 or so. Any help as to why it lags on that one test would be most helpful!....well, would be SOMEWHAT helpful. A FIX would be MOST helpful lol
Thanks!
I don't think quadrant had been updated to run properly on ICS so it may not be pulling the GPU to render that scene. So you may not need a fix because what your looking at and what quadrant may be reporting could be incorrect.
With root explore go into system/lib/egl and delete eGLES_android.so then reboot and the plants will run around 56-60fps

Wow thanks that worked! what does that file do anyway? Does deleting it have any other impact on the phone?
And it looks like you were both correct because even though the fps on that test improved, my score his exactly the same lol
Thank you for the replies!

Like I said. Quadrant isn't updated to know what its supposed to test.

Low benchmark scores after franco kernel r33

i used to get around 32k in antutu and around 18k in quadrant before franco kernel r33 but now i am getting around 24k and 11k respectively i highlt doubt this is due to kernel (i didnt screw up anything (no custom roms nothing...)) can some confirm this ?? plzz
Why does it matter? Does the phone still run good? Can you notice any difference while using your phone normally?

in practical sense the phone works perfect apps run smoothly and battery life is awesome (5-6hrs)...but theoritical sense why did the scores become less ?? did franco limit the processor speed or something??

sir , can u plz run antutu from ur phone (i.e if ur using franco kernel)? and tell me ur score i know this may sound childish and geeky whatever u call it but it is still important for me

This bit is the only thing you should be caring about...
The 'score' is meaningless. Let it go, uninstall any benchmark apps and don't bother running a test ever again.
Put it this way...if you suddenly scored 234069823987693827469823764 after flashing a new kernel, but performance and battery actually got worse, which one would you prefer?

Hi,
Franciso explained that he had decreased the CPU temp limit before thermal throttling, that could explain your lower score (earlier thermal throttle)... Check also your max CPU freq.
Let cool down your phone before you run Antutu and see, or play with the thermal settings (raise a bit the CPU temp before thermal throttling, core also).
The user is in its right to know why he have a lower score in benches between two different version of a kernel, whatever if a bench is useful or useless... Obviously if all is smooth and run perfectly for you, it's the principal.
nexus 5 is high end device, benchmark score doesn't effect the performance of device using any kernel.
i never experience any lag on my nexus, i always get different score in antutu.
r32 I got around 32k with antutu now I get around 29k on r33 but battery life is so incredible I'm willing to sacrifice benchmark points useless in day to day use .... isn't benchmarking moslty about bragging?
thank you very much
