[KERNEL][AOSP/TW][27 Dec] War Kernel r3 // colder than ever
- Thread starter GeeckoDev
- Start date
Agreed. I tried reflash the ROM and kernel without the MOD, the ROM runs smoothly too. Cheers
+1. All that I miss in this kennel are few additional Arnies
SmartAssv2, HYPER and Lionheart would be awesome. I remember from my LG P970, that Linheart was amazing. Very battery friendly, yet great in terms of overall performance.
I don't have the time or the motivation to add these schedulers. To me it's mostly placebo and barely make a difference.+1. All that I miss in this kennel are few additional Arnies
Not entirely placebo. One thing that must be understood, is that a P970 is quite different than a N7000. First dual core vs single core, then the power profile, e could go on endlessly. The sweet spot of our cpu is in getting the most performance WITHOUT reaching the thermal throttling. Also, because of single vs dual, not every governor is suited to the task...
I've read somewhere that the best governor for our cpu is still the pegasusq, followed by ondemand. Yet, i miss Interactive and it's touch-boost feature
Yeah, pegasusq seems a bit less dumb than ondemand and is multi-core aware. I'm not sure what you mean by "touch-boost", but I think there's a similar feature with pegasusq. Check the frequency when you touch the screen, it's never under 500MHz.Not entirely placebo. One thing that must be understood, is that a P970 is quite different than a N7000.

One other area to improve performance is to set the thermal threshold higher, but I won't destroy my Note with this. Anyway, our hardware is fast enough, it's just a giant software cluster**** that kills usability. The most annoying thing is not that the framerate is low, but rather inconsistent.

You're the guy who knows that s**t better than me - a simple user and a consumer. That means, I am downloading Raw r4, which will replace Asylum 3.0.64.BTW. After about 2 months of using SmartAssV2 I hope, that Pegasusq will be more battery efficient and hopefully nearly as fast
Well, IIRC interactive is one of the many parts of project jellybean. Two settings i refer:Yeah, pegasusq seems a bit less dumb than ondemand and is multi-core aware.

hispeed_freq -> Hi speed to bump to from lo speed when load burst.
input_boost -> Immediately scale to the hispeed_freq on touch input.
hisped_freq is not the max clock, just a pretty high clock that it's jumped to on any touch event. That, allied to go_hispeed_load, above_hispeed_delay and min_sample_time guarantee a pleasent cpu experience without THAT much battery waste (assuming the values are not crazy)
If this setting exists on pegasusq (even withouth any config available) it's quite broken. Observing the cpu freq, a touch can get me 500, 800 or 1400.

I have set max cup frequency at 1200mhz @1075 mv and it almost solved the thermal throttle problem.Yeah, pegasusq seems a bit less dumb than ondemand and is multi-core aware.

At 1400mhz the cpu very quickly reaches the maximum temperature, i think that increasing the maximum temperature from 65C to 70C would give many improvements and do not think that damages the cpu.

I am using the xposed module "cputemp in status bar" for see the cpu temperature.

Nice, let's try it
True, the secret lies on not allowing the device to remain there for long. Also, since ICS/JB is gpu acelerated (in contrast to GB), the cpu speed is not so important.
Depends, most chips allow for some margin, but you don't want to find yours the hard way do you ?
Carefull there, that Xposed module reports a temperature, but you'll never be sure if it's the soc or the battery temp.
Now, one thing you're forgeting is the GPU... that's a major heat source. And mine has all it's 3 levels overclocked.

On the N7000 there is no board sensor. The readings are from the battery sensor.
It is the cpu temperature

The battery temp is generally much lower and you can see it with another app

Try open an heavy app like google maps, with the maximum frequency at 1400 MHz, in seconds reaches 65C, it activates the thermal throttle and the temperature drops, at 60C the termal throttle is disabled and the temperature rises again.

Sure... I have undervolted it too
I am using 160 mhz 800mv, 200mhz 875mv, 267 mhz 950 mv.
But the major heat souce i think is the cpu.

It's very difficult to use GPU without the CPU being abused also. The inverse not so true. Yes, the CPU is the major source of heat, but the GPU overheats much more. REmember, a GPS uses the GPU to draw the map. A GPS app is not so cpu intensive, perhaps when calculating route, but is quite GPU intensive.
Well, the s3 got the android 4.3 update:
http://www.sammobile.com/2013/11/04...olling-out-for-samsung-galaxy-s-iii-gt-i9300/
According to sammobile, it comes with the new GPU drivers ("- GPU drivers have been updated (Higher GPU benchmark scores)
"). Let's hope that they release the kernel source code soon (which samsung usually does anyway, shouldn't be more than 2 weeks judging by their past history).

Yep, saw that as well! I think we will have the sources before the end of this week. It took 5 days for the Galaxy S4.
Looks like I'll have a busy week-end
Mate... Your work is just amazing. I've never tought, that your kernel is that goodYep, saw that as well! I think we will have the sources before the end of this week. It took 5 days for the Galaxy S4.

Comparing to AsylumKennel, after 2 days I can see better battery efficiency, phone is running smoothly and it's incredibly stable I'm sticking to RAW till my Note dies
