Flashed this alpha M Kernel. After settling it's running pretty well so far. Will report back after pitting it through the paces. No lag and everything quick fluid so far.
[Nexus 7 Android Development] Jay Aristide:
Will do. Also having a time with Death Dome.. damn game forgot all my fights but I kept my gear. Forgot my xp and skull doubler, too and that was like 65 credits... also kept skulls and credits. Oh, and now every enemy I get besides bosses is bruiser...

Wtfmeng

Thanks, the kernel works great, I'm running 100-1300 MHz -50 mV, everything feels fast and smooth. The only issue is heat: the device heats up considerably during a simple benchmark. I

Would it be possible to lower GPU and/or LP core o/c?
[Nexus 7 Android Development] G.Goret:
Thanks for the great kernel!

Do you have plans to update the "M plus" with stock and 484MHz GPU settings?
[Nexus 7 Android Development] O2Blevel:
With android 4.2 coming out near the end of this month, will this process of redoing the kernel have to be repeated?
[Nexus 7 Android Development] MetalPainis:
Without a look at the sources that's not really predictable. But since they always try to improve speed, battery and balance + smoothness, it's highly likely ;)

I seem to be getting much worse standby time on my N7. I fully charged it the other day, used it down to about 90%, then let it sit idle for about 36 hours. I came back and it was at 57%. In the past, I would lose at most 10% a day - but usually more like 5%. It could just be coincidence, or possibly something to do with the rest of the 4.1.2 upgrade, but though I would mention it.

Can you release a 520mhz gpu version please? I need the extra performance for Gameloft games like nova 3
[Nexus 7 Android Development] mrbeardy:
Ive been running the M-Kernel Plus since the 16th and its been performing well and appears quite stable, first charge got 7h45m screen time over 3 days, browsing and games. Overclocked to 1500 and interactive governor.

I havent noticed it getting any warmer than it did before, but i will monitor the cpuspy readings and see if its the 620 doing it.
[Nexus 7 Android Development] prestige777:
I've been using the m kernel for the last couple of days, it's stable but runs hot for some reason, just browsing makes it pretty warm. The processor

froze up on me just now, I had it on1300mhz and it stuck there, the tablet didn't freeze up, but it was getting pretty hot, a reboot fixed it. With the classic kernel and the screen off, the screen would feel cool to the touch with the draft from the a/c blowing on it, with the m kernel its warm all the time, battery life is great though.

Battery life was a little on the short side, not too bad.
[Nexus 7 Android Development] kzakhar:
I'm also having a weird sound issue with the alpha kernel: instead of a normal output the device randomly produces a crackling sound, then the sound output stops completely until another application produces some sound or the device is rebooted.

I didn't have this issue with other kernels, including motley 4.1.1 or classic 4.1.2 (now removed). The device is running at 100-1300 MHz, -25 mV u/v as usual.

What could be causing this?
[Nexus 7 Android Development] Kearkan:
I'm getting the random sounds too. The time I notice it the most is when I unlock the tablet, just as I slide across to unlock it there is a very noticeable 'pop' noise, if I straight away lock and unlock, it doesn't do it again, but if it puts itself to sleep and I unlock it it does it.

Also heat is a big problem, I've been playing offworld for about 20 mins and system tuner is saying the cpu is at 57C. And along the left side toward the bottom of the tablet (when holding it in portrait) is very hot. In the time I'm writing this its cooled back down, but before it never even got that hot playing thd games.

Hope this can be fixed soon, might be a good idea to keep the classic kernel up for those worried about the heat till its fixed.
[Nexus 7 Android Development] tobitronics:
Having this issue here too. Didnt notice heat yet, however i dont play lots of 2d games, mostly i play gameloft type games.

Hey.

Just tried to flash this kernel this morning but it didn't work : (

Currently running the latest Cm10 nightly. Was using the 4.1.1 motley and it worked super.

Flashed this but now it won't boot. Not even recovery! Just gets to the boot loader.

Can anyone please explain why?

I get it. I could have included all the PMs as well, but I figured this was enough to make my point.

I understand you have a problem. Things take time to figure out and fix. That's assuming there actually is a problem. Believe it or not, but I actually have a life and other commitments that take precedence over making sure your happy with the kernel.

[Nexus 7 Android Development] Metallice:
You could have just held power and volume down until it rebooted to the bootloader... entered recovery... and installed a19...
[Nexus 7 Android Development] jombo2323:
no, i dont know if its a bug with a couple month old twrp but for me it has to be plugged into a computer with the fastboot/bootloader drivers installed before it will boot into recovery, UNLESS, i do it from holding the power button down in android, clicking reboot, then clicking reboot to recovery. :(

if you guys dont have to do this, tell me so i know whether or not i should update twrp

Also just saw you put up a22, whats in store for this :S
[Nexus 7 Android Development] Metallice:
It's a bug with the old bootloader. You need to update to the newest one. There are flashable zips for it around here. Just search.
[Nexus 7 Android Development] jombo2323:
jeeze, first of all, thats only semi-safe, right? it could cause my device to be perfectly bricked because if the bootloader is messed up then you cant do ****. and secondly

of course its not the obvious XD

anyways, i cant seem to find the newer bootloader other than one for 4.1.2 that "fixes" that problem.

possible you can post the one you used? or give me a link?

also, flashing a22 now, if it doesnt boot, im gonna **** a brick

Thats the s word btw, i wouldent want to F a brick :l

[Nexus 7 Android Development] jombo2323:
nice timing metallice, i flashed it, rebooted, waited while it was on the google logo for a minute, nothing happened, went and took a leak, sat down and it popped up on the homescreen.

You wouldent happen to be able to add other governors in like powersave would you? it comes in handy when you dont care how slow it runs, but it saves power and can still run fast if you push it hard enough

Happy to report that a22/666 is running great so far. Apologies for everyone who had to read through all of the testing posts between Metallice and I, but a small inconvenience for what came out of it IMO, thanks for bearing with us. Loving how trickster compliments all of the voltage settings in this kernel now. Now I just have to spend some time tweaking the voltages although I'm a bit hesitant bc everything is running so well right now. Maybe somebody with a little more experience in that field can share some of their settings.

Keep up the excellent work Metallice, but not before you finish your studies ;) And then you can treat yourself to a drink on me Confirmation number: 6MP87244PK8946714. :good:

Alright time to unplug the router and get working.
[Nexus 7 Android Development] Stuphologist:
Thanks! I didn't know there was a solution to that little annoyance.

Also, A22/550 wouldn't boot, but A22/666 did. Except that after I flashed the new boot loader my N7 wouldn't boot. I about had a stroke. But it did (whew!) go to the boot loader and from there I re-flashed A22/666 and then it booted. Was that expected? I don't at this point know if flashing twice would fix A22/550, but it feels possible, so I'm going to give it a try.

As it turns out, though my N7 really is vindicated. It can run a 666 kernel, so apparently it's just an oddball, not a wimp.

But enough! Aren't you supposed to be studying?

Since some are having mixed results:

a22/666 running fine on Clean ROM.

Settings

GPU 520

CPU 204 - 1500

MinFree tweaked a bit more aggressive.

Everything else what ever is baked into the kernel. It's running very smooth but not as snappy as I have seen. Don't get me wrong it's not slow at all. If snappy is 10 this is about 8-9 with no laggy spots.

A22 still giving me the same oc issues. Does anyone else have trouble hitting 666? As I said before I don't think its my device as trinity gets it to 700+ no problem.

Do you know if there is a difference between this and trinity that could make it have this reaction? It's not actually rebooting, it just freezes, sometimes as soon as I apply, sometimes after a minute or 2.

I'm going to try the other usergpu versions to see if any of them get there.

Update: clean flashed pabeta6 and the kernel (only formatted system) and gave it a while after booting to change anything, my tab is now about half way through a gpumark benchmark.... And now just restarded as I was halfway through this edit =\ was at 666@1450 on a22

Btw metallice im sorry to be a pain about this, if it turns out I'm the only one experience this then ill leave it, 600 is enough of an oc anyway, its just odd considering i know under other conditions I can get these speeds =S
[Nexus 7 Android Development] Kearkan:
Just tried gpu oc with Franco, did 750mhz without an issue.

I'll keep trying but because I prefer m-kernel.

a22 666lp boot correctly here, but ui is slightly less snappy than with a19. Furthermore, with a22 my device is not very stable (even with max CPU = 1300 mhz) and antutu often crash. scores are on par with a19 when benchmark does not crash.

I tried Franco kernel and antutu score is higher than a22. However, with that kernel, I almost can not increase the lp freq. Even at 550 my device crash.

a19 LP666 with GPU 550 works fine for me, however after flashing a22 LP666 it hangs at the pattern lock page.

Then, proceed to try a22 L550 and it works fine. A little puzzled on the difference, what is LP actually?
[Nexus 7 Android Development] Kearkan:
Well, I spent the whole night trying every speed/voltage combo I could, I even did a proper clean wipe/flash (system and data) with pa beta 6 to eliminate anything else being a problem.

The best I could get was 620@1300mV

The voltage seemed to be unrelated to the reboots but, I could push them wherever I wanted at lower speeds and it was fine, but the second I put the speed up, it would freeze and reboot usually the second I hit apply in trickster.

Flashed both trinity and Franco, and still using trickster I pushed both all the way to 700, Franco actually went right up to 750.

This was mostly on a22, but a19 had the same problems this afternoon.
[Nexus 7 Android Development] jombo2323:
If you are having trouble hitting frequencies, bump op the voltage. For example.....

Whenever I turned the GPU above 500mhz, it would get me terrible fps on anything and putting it on 490 fixed it. In trickster mod, I turned up the high side voltage on it up 30mv now it hits 700 and is buttery smooth

---------- Post added at 02:01 PM ---------- Previous post was at 01:58 PM ----------

Sorry for double post

LP is the one on the quad plus one CPU. Basically its the low power companion core that runs when your not doing anything heavy to save battery
[Nexus 7 Android Development] Kearkan:
That's what I've been doing, I have been doing about +100 - +150, ill try a smaller push to see if it makes a difference but I don't see how that makes much sense.

The issue isn't framerate, this issue is the second I apply the speed my tablet crashes

Update: did a +30 didn't even get "applied" pop up in trickster before it froze

[Nexus 7 Android Development] jombo2323:
The auto brightness is something that can be turned off with trickster. The actual auto brightness where it flickers is fixed by covering the WiFi ground connector with a small piece of tape

Jesus, you might just be unlucky..

Wait, actually

Turn it to the highest GPU clock possible with no crash

Close trickster

Open trickster

Go back to GPU voltage table. The new highest value is your previous max oc instead of the 446 or whatever stock was

Try turning up the voltage on that.

I was turning up the voltage for 600mhz GPU speed when I did that.

Hope it works ;)

Edit*

Just thought I should give you numbers.....

@600mhz I was running 1230mv no problem 700's voltage was auto calculated by trickster

It always does for some odd reason. After flashing any kernels, not anykernel, it takes a long time to get off the Google screen. Just give it time. It can take up to 15 minutes in some cases
[Nexus 7 Android Development] Metallice:
I have an idea of what your issue may be. After finals I can try.
[Nexus 7 Android Development] jombo2323:
You should put in the first post, for extended battery life with minimal performance loss, in trickster mod, edit the ondemand governor up threshold to 95 and turn sampling rate to 40000

Got me ~30-45 mins of battery under normal use
[Nexus 7 Android Development] SpikeySpy:
so does it mean that 550 saves more battery than 666?
[Nexus 7 Android Development] jombo2323:
Yes and no, and I think metallice should read what I have to say.

In theory, it switches to quad core once the companion hits x usage

Its much more efficient to run a single core than a quad, even if the single is over clocked.

So.....

That means that being over clocked, the single cores usage is generally lower because of more clock cycles per second

So that means it should technically stay on the single core longer, saving battery.

In theory the lp666 should be the most efficient.
[Nexus 7 Android Development] Metallice:
No.

That governor never runs fast. It's designed to run at minimum frequency at all times no matter what. In this case it would run at 102 constantly. Pointless.
[Nexus 7 Android Development] jombo2323:
What about a performance battery saver?
[Nexus 7 Android Development] jombo2323:
Like a performance mode that is easily affected by CPU usage. I guess what I mean is like another on demand, like ondemand2 so I can set it to jump up frequencies when it hits 40% usage but keep my battery saving one
[Nexus 7 Android Development] SquireSCA:
Using Trickster, what's the most performance oriented governor to use? Not too worried about battery life, I am always near a charger, so having 30-45min less isn't an issue for me.
[Nexus 7 Android Development] Metallice:
Interactive. Although you could use on demand and set a low up threshold in governor settings. I would personally recommend the latter.
[Nexus 7 Android Development] Nburnes:
"Performance"....Though it will run at Max freq the entire time so you will have far less than 30-45min less
[Nexus 7 Android Development] Metallice:
Not going to happen. Sorry. Up threshold is a user controllable parameter for a reason.
