Performance improvements

hi , i know the change log is "Update to Kernel 3.0.61 source".

Are there any performance updates because of this over Nova Kernel 1.4??

Also can you make a version for Xperia SL with 1900MHZ or 2 GHZ Processor speed since my stock processor is already 1.7GHZ. Thanks in advance.

It's not safe. SL has same chipset as S, so it safe to overclock to 1.7 Ghz.

I know this has been discussed before and i forgot who answered me that it had problems with linking and stuff like that, but i see its compiled with 4.4.3.

What is the possibility to use another one? ie 4.5,4.6 or 4.7?
[Sony Xperia S, Acro S, Ion] qbzee007:
Thanks for this kernel it works like a charm.. havent had any problems except for some random reboots every now and then, which i am willing to live with.

Just a quick question (i am not sure if this is the place to ask it). Is it possible to automatically shutdown one core after the battery level reaches a certain level in order to save battery. if so do i need an app for that or what.. otherwise thank you again.

I dont know whether it happened to someone else or not but after playing game for some 15-20 min the first cpu clocked to max 1728 mhz even I set it to 1620 mhz on boot.Whereas the second cpu reduced its mhz.I can understand to get reduced when temperature increases but increase,that too on 1st cpu

Hy Hei 1125

I use your kernel ver. 1.5 with PA 2.57 ROM. I use Intellidemand and SIO at stock frequencies. Your kernel works great, and am very pleased. I see you've implemented Letama patch for the sound, which works well, however, when I begin to talk on a cell phone earpiece sound level is always the same. Only when I press vol + or vol - the sound to reduce or amplify.

I'm not sure if you and I noticed this problem?

PS

Do You follow the old thread of LG O2X, I see that there are plenty new ROM's based on CM10 (CM10.1).

Thanks for great kernel and keep the good work.

Yes, it's normal. But it's annoying. I've experienced lag when the phone's getting hot :)

And the first core setting should intact. What's your overclock/cpu application? Or, I don't think it's matter, but what's your governor for cpu0? The increase should be happen only in the second core. As it can get a fully offline (and forget its settings), while the first core can't go fully offline when your phone is on.

when I was on ICS (KA SSPEED ROM) I tried a few times OC to 1.89GHz but it was no-sense, because when running some Benchmarks, phone got so hot that it decreased frequency and the final score was lower than on 1.728GHz for example :) and when I was playing games, my phone sometimes overheated so much that it rebooted itself and than it was problem to start it because it was still hot...but agree, we are on Android so if there is some posibillity to do something, it should be done and users can decide it it fits their needs ;)

dunno then. maybe change your governor to something else. like intelidemand or something. and did your cpu1 setting's stick? or u dont lower the max freq for cpu1? imho, it's not really good if u lower the freq of cpu0, as for cpu1 it will always go to max freq, so you'll get wasted resource. it's better to use better governor that scale nice, or if u want, do the undervolting. i've tried myself, the cpu0 max freq setting in kernel turner always intact, even when it got hot, or when after deep sleep.

if ur phone's hot. the max freq will go to 810 mHz. not to 1.1 gHz.. :) there's something else that cause this.

i've this problem too. idk what's the cause. maybe the governor, or it's in the Antutu itself. my workaround to this problem is: change the max & min freq for both core to 1.7 gHz (in Kernel Tuner) and change the governor to performance. then my Antutu showed 1.7 gHz. :)

when you are working with phone and ondemand, can you see (in for example Kernel Tuner) that both cores are used and running on freqs higher than 1134MHz??

---------- Post added at 03:04 PM ---------- Previous post was at 02:57 PM ----------

Deadline is your selected IO scheduler, it has nothing to do with GPU (which is currently OCed in this kernel) and I was using it before, now I use SIO, you can try it, it's similar, but I have a bit better performance with it, according to BMs results

and also Sampling rate and Upthreshold values have nothing to do with GPU, these are settings of OnDemand governor ;)

but, if your phone changes these values, try to install Kernel Tuner (for me it's the best) and set all things there and check "Prevent other applications changes" or something like that, or uninstall (freeze) apps you use now for setting CPU like Set CPU etc., it seems that some other app is "talking" to your CPU settings

Re: [KERNEL 3.0.61][GPL][JAN28] Nova Kernel v1.5 | Butter Smooth & Battery Save

Please read few previous pages. This has been discussed before. I'll say again for last time: when the phone's hot, the Max freq will go to 810 MHz, not 1.1 or any other freq. Unless you alter the /system (which is unlikely)

And I saw that by setting it to performance (and ondemand) gov., u got the 1.7 gHz again in antutu. So what's the problem now? And I do think that u should use performance governor for benchmarks. If u worry bout small difference in scores (as long as all those scores came from same freq, not the lower one), take a good look in detailed score (in antutu). From my experience, the things that got lower easily are: ram, database io, and sdcard read/write. So I think it's better to reboot first before do the benchmark.

And lastly, I don't think that antutu matters much. If ur most enjoyed games (or apps) are getting lag while in other kernel (with same rom) or other version of this kernel, ur getting no lag then you can ask the developer about it (though he/she have the rights to ignore that. :D )

[Sony Xperia S, Acro S, Ion] nhnt11:
I've been undervolting bit by bit for the last few days and I've stopped at 1087mV for 1728MHz as a stable value (couple of reboots at 1065). I'm surprised at how low it has gone - what's the usual safe undervolt for this cpu? An average perhaps?

Anyways, my other settings are:

CPU0 - 192-1350MHz intellidemand

CPU1 - 192-1728MHz interactive

Mpdecision - Threshold Up load 65%, Down load 35%, Idle freq. 192MHz

OOM at 512 aggressive (still playing with this though, need to do more research)

So far it's been smooth and zippy, and I've been getting decent battery life during the tweaking process (easily a day of moderate-heavy usage from a 70% charge). I think I'll keep the current settings and see how the battery responds for a couple of days.

Edit: I'd appreciate it if someone could mention exactly what the OOM values signify. For example, what exactly does a value of 8MB or 120MB mean?

[Sony Xperia S, Acro S, Ion] nileshgr:
Re: [KERNEL 3.0.61][GPL][JAN28] Nova Kernel v1.5 | Butter Smooth & Battery Save

The OOM values are basically priorities. I don't know why it is displayed in terms of megabytes.

The empty application will get killed first when you run of memory then the next from below and so on.

I'm on the 512 multitasking profile, zram at 10% with swappiness at 1% (modified /system/bin/compcache).
[Sony Xperia S, Acro S, Ion] nhnt11:
Hmm. My guess would be that the megabyte value is the amount of free RAM left before that category of app is killed.
[Sony Xperia S, Acro S, Ion] m1st3r1:
Re: [KERNEL 3.0.61][GPL][JAN28] Nova Kernel v1.5 | Butter Smooth & Battery Save

The megabytes tell you what's the amount of available ram needed for android to kill apps in one of the groups. Eg: u've set 120 MB for hidden applications means when ur available ram goes to 120 MB, the apps in this group will be killed. And so on, so forth.

Bigger value of these oom, will give you faster performance in single app (meaning no lags, cause most of lags in android happened when android killing other apps when that single app needs more ram), as the other apps will be killed so that the single app have more available ram for it, apps (mostly games) need bigger and bigger ram when it's running, so if u made bigger value of oom, it'll be killed beforehand, not when the app's running) but u'll lose multitasking and it'll be little slow when opening new apps.

So if ur favorite app is lagging, change these oom is recommended, but if u feel there's no lag, leave those settings, as the one of main selling point of android is its multi tasking.

And I think that this explained why the amount of available ram is not necessarily matters for android.
[Sony Xperia S, Acro S, Ion] nileshgr:
Re: [KERNEL 3.0.61][GPL][JAN28] Nova Kernel v1.5 | Butter Smooth & Battery Save

Cool, thanks for the information.

On the same lines, I remember reading somewhere "free RAM on Android is wasted RAM"

Also there's the zram thing which contributes some to multitasking.

The kernel by default comes with swappiness as 30%, I found that my phone was spending to much CPU moving stuff into swap (zram), so reduced swappiness to 1% which means it will use zram when it totally runs out of memory.

Well, each CPU differs. You got a really good chip when you bought your device. Since silicon diodes don't work below 0.7/0 8 volts, 0.8 volts is the dire minimum.

Mine doesn't undervolt below 1200 mV for 1728 Mhz, phone freezes and reboots.
