[DER KERNEL] Trinity Seven (4.2/4.3)

Remoteconcern · Aug 5, 2012

Just turned off force CPU online option, and I'm hoping this explains my bad battery life.

I think this option is turned on by default, which should probably be changed.

Just out of interest, is the same toggle on the Nexus prime trinity kernel also best left as offline for battery? It defaults to online. I always assumed that offline meant you were forcing single core, and now I'm confused.

Thanks guys.

online means all the CPUs. offline isn't all of them. in the nexus prime, shutting off one CPU might save a little battery, maybe. but at a big loss in performance(rendering issues in the browser/ gallery). I leave it online all the time. in the nexus 7, leaving it online all the time will lead to excessive heat and battery loss. so, while the concept is the same on both devices, it leads to different outcomes. BTW, if you don't enable it in the nexus 7, it'll still go online from time to time, then back. only when the n7 decides it needs all four CPUs. you just don't want to enable it manually, so that they are all running all the time. except for benchmarking

So what's everyone using for governor and scheduler?

Apothegm · Aug 5, 2012

My N7 doesn't seem to like anything past 1.5, regardless of any settings. But the way I see it... if I can feel or show a performance difference at the stock clock speed then the kernel is an improvement and not a bunch of useless placebo additions masked by overclocking. Morfics kernels have always made my devices better, even without overclocking. So I'm happy even though I won't see 1.6 on my device.

However, on my d2tmo... the 1.8xx works like a charm. Thanks for all your hard work morfic.

Well I joined the party here as well

Morfic, I know you don't Dev strictly for the money but I will seriously pay for just one Sprint variant S3 kernel. I have TeamViewer so you could work off of my phone. I am not talking $20 either. I will take care of you if you can make one

hmm..
i dont know that i would trust someone named John Corleone to "take care" of me.. :silly:

I will donate $50

Where's the 1700+ builds? I am cruising along at 1640...edit...can someone post an Antutu link, shows not compatible

btw, from your screenshot, turn fsync off and turn on force gpu acceleration in developer settings

Was playing it safe. I wanted to see if it made it through some tests with fsync on

the option is only in alpha37, none earlier.

Getting some lines/artifacts on 37. Had to flash back to stock kernel just to make sure I wasn't seeing things. Is the GPU oced in 37?

install on phone, move from phone to The Seven
via dropbox, adb, your choice

Yeah, back on 446MHz and while it seems less noticeable, i see the occasional jump on screen , presumably when switching frequencies because it tends to happen within a time frame of not using it, while swiping, opening apps, displaying things it behaves.

Edit: Stock is 416MHz, so it's a measly 30MHz to bring on the glitchyness.

Same here, mostly on tapatalk though.

Damn just 30mhz, was hoping for a bit more headroom than that. Granted it doesn't really need more power but it's fun to see how far you can push it.

Speaking of which, does anyone know how cold a temp is safe to subject the n7 too? Can't seem to find operating temps anywhere

Code:

pcm.usbdac {
type hw;
card Audio;
}
ctl.usbdac {
type hw;
card Audio;
}
pcm.!default usbdac

Back up your asound.conf and add this (or for simplicity sake, replace it with this)

This allows me to use my Nexus 7 to play over my Fiio E10 USB DAC, N7 + E10 + HD380 == fun.

it's too late for me to work on combining this with the stock asound.conf

We are lucky, no such file or luck on GN or SGS3 yet, need to first understand how alsa works on those phones.

This kernel is dirty.. check this battery life. On pace for nearly 10hours of on screen! ;S
