Re: [KERNEL][3G+WIFI][4.2.1] M-Kernel - a36

Sit down and shut the... I mean chill. a36 was dropped what, 24 hours ago? Metallice has developed a very well respected kernel for both performance and battery life. And he has made it very configurable so the benchmark and battery life chasers can push the kernel as hard as they want.

If you feel the need to report a benchmark, report it and let it go. Let the result stand on its own and let people take from it what they will. The whole defending the usefulness of benchmarks is a VERY/VERY tired and useless topic for a post.

a36 feels fine to me in how I use my device. And it feels no slower that the other kernels I tired this week. But I haven't pushed it, but I will now with Zen pinball because more I'm curious.
[Nexus 7 Android Development] eduardo_b:
Benchmarks are overrated. In the real world, it's battery usage and performance while using a phone, tablet, laptop/notebook that matter. If these are good and the hardware runs reliably, benchmarks serve no purpose other than to distract one from what actually matters.
[Nexus 7 Android Development] ezas:
Re: [KERNEL][3G+WIFI][4.2.1] M-Kernel - a36

I set my usual settings (1500/520) and Zen Pinball played the same it always has. I played it first on standard quality and then enhanced to see if there as a difference and enhanced felt just as fast.

For giggles rebooted to all default kernel settings and Zen Pinball played pretty much the same. Maybe a hair slower. It was as smooth but my timing was a bit off on the flippers. This may not be the best test since it runs the same on both default and OC settings, but it's my 'benchmark' and I have run it on many kernels.

Update: I decided to do some other testing to see if Zen Pinball does push the CPU/GPU hard enough too make it a somewhat valid comparison of kernel performance. And I can say with confidence that it does.

I'm using Dirty AOKP 4.2

Re: [KERNEL][3G+WIFI][4.2.1] M-Kernel - a36

I'm more officially sick of Zen Pinball.

I want to make clear that I understand that metallice is trying new things and is always trying new things. This is a kernel that is in development.

I have run 5 kernels thru my device this morning. 3 by other devs and a36 and a35. a35 is faster and is as fast as anything I threw at it. a36 was about on par with two of the kernels I tried, and one kernel was only matched by a35 for game play. In all cases Zen Pinball was smooth and had good game play. a36 at default settings has not turned this kernel into some performance basement dweller.

======

In short, in sound compression is making the quieter stuff louder and the louder stuff softer. Depending on the settings the effect achieved can vary greatly. That's the two sentence description. Wikipedia has some good articles on sound processing. Try searching on audio compression and/or limiter.

Benchmarks, and reporting benchmarks, and installing benchmark apps is gay. I for one prefer to actually use my device instead of staring at lame benchmarks. I don't even understand why people bother since THEY ARE NOT ACCURATE. It’s like those retarded "Internet speed" tests. Waste of time, battery and device life.

[Nexus 7 Android Development] skylinegt77:
to those who say benchmarks arent accurate, that statement is right for most benchmarks, though it doesnt apply to cf-bench for example, i tried running it with 2 different p990, and also tried runing it with 2 different nexus 7, and results were very consistent, with the same rom, same kernel it wont give u even 100 points difference between 2 similar systems, plus, usualy benchmarks arent accurate due to background apps eating up resources, therefore if you eliminate the background apps from the equation, you will have a much better starting point to compare 2 systems. but i would advise to stay away from easily influenced benchmarks such as quadrant which can be fouled into higher scores just by simple tricks and scripts. also qhen benchmarking graphics you should go for a benchmark such as nenamark that doesnt give you any higher scores due to increased fps limit.

So out of curiosity, I tried motley's kernel for a week and it gave me better battery life than this one. I just flashed a36, hopefully it gets better this time, for battery is important for me at this time because I am busy at school.:3 Anyway, I do prefer this more than motley's because I can OC my gpu a little bit. Just a question though, does increasing my touch_min_cores affect performance and battery drain?
[Nexus 7 Android Development] skylinegt77:
i would surely tell you that if you have a higher drain with this kernel than u do with motleys is because you did something wrong, coz theres no other possibility, no other kernel out there can touch this 1 when it comes to battery life and trust me, i tried em all ;)
[Nexus 7 Android Development] Leonhan:

AW: [KERNEL][3G+WIFI][4.2.1] M-Kernel - a36

It's not limiting the overall number of cores, it forces a minimum number of cores to be active on touch interaction.

Worse for battery life if it is not needed, but might improve the perception of smoothness.

As this is clearly subjective, everyone should try for themselves if they notice a difference.

[Nexus 7 Android Development] FReaKRaNT:
Re: [KERNEL][3G+WIFI][4.2.1] M-Kernel - a36

According to Metalice it is more or less hype until Google releases a future OS that actually will be coded to use 4 cores. Right now all it uses it for is stuff like swiping widgets. Other than that the 3rd and 4th cores don't even come on. Best thing is to test it and evaluate for your self.

Cheers, FReaKRaNT
[Nexus 7 Android Development] SquireSCA:
So while I understand that benchmark scores are not the end all be all of gauging performance, they do have a place. Disabling or not using 2 cores can help battery life, but there is a performance impact somewhere, no?

Like maybe when the device is multitasking? Downloading and installing apps in the background, updating widgets, etc...?

And what is really weird, is that I am running A36, but I do not see in Trickster MOD where you can change the min core value. My Antutu scores are down in the 7,000 range which is half of what it used to be.

[Nexus 7 Android Development] adstraylight:
I know - but thank you for explaining it to those that didn't ;) ,and I wasn't asking which was better 2 or 4, I can, as you say, make my own mind up on that. I do find it curious though that turning off 2 cores that are barely being used anyway saves so much power (going by the anecdotal evidence here).

On a different note, for those gamers that are seeing occasionally stuttering graphics: I installed Temple Run 2 (and do you know - it's actually rather good :) ), to see the problem for myself. After much messing with the settings I think the problem lies not with the GPU but the CPU, as the problem persists when you turn off 3D scaling, and so run the GPU at max Mhz. BTW, the problem only shows up in TR2 when using the highest graphics quality, and all that does is add proper shadows to the characters AFAICT.

After more experimentation, I all but eliminated the issue by changing the sampling down factor from 2 to 4 in the touchdemand governor settings, so I contend that aggressively ramping down the CPU speed to save power may impact some game engines.

I hope this helps, and it's not just on my device :laugh:

Re: [KERNEL][3G+WIFI][4.2.1] M-Kernel - a36

The only difference I see between a35 and a36 is that Antutu scores on a36 are 2/3 of those on a35. In terms of perceived performance I can't tell any difference - both are smooth and snappy.

Battery life for me has been the same on a32, a35, and a36. I lose 10% per hour of screen-on time plus 10% per day.

So, from my perspective, there's no value in limiting the device to just 2 cores. You might just as well leave the settings as per a35 and avoid the hue and cries about poor benchmarks.

I'm on CM 10.1 or Saber mod, and I use my device for browsing, reading, and watching movies. I don't play games on my tablet.

Not wrong actually, but coming from a different perspective -- discernible as meaningful.

I remember over the years all the benchmarks for different Windows setups -- hardware and OS tuning -- and how quickly apps would boot in numbers of seconds. Yes, there were differences, but they weren't enough to actually matter, and became irrelevant after app was open.

Re: [KERNEL][3G+WIFI][4.2.1] M-Kernel - a36

I have not seen significant difference using two or four cores, neither in performance, nor in battery life. Looking at the stats, it seems that most cores are offline anyway.
[Nexus 7 Android Development] grooltor:
My two cents. If Android is made to use only two cores, you can leave 4 enabled without draining the battery too much. They will be activated only when really needed, so they won't impact on battery life. I leave them enabled, so OS can use them if needed. Most of the time there'll be only 2 cores active. Rarely you'll see all the 4, in those cases when needed. So no big performance gain, nor battery drain. Better to have the possibility to access all the 4, it's stupid to limit them in advance, IMHO. :)
