This kernel is so much faster than any other grouper kernel. Just one word: WOW! Love that mpdecision-thing :)
[Nexus 7 Original Development] aLNG:
this kernel is for jss or jwr rom?
[Nexus 7 Original Development] slebit:
Should work with both.
[Nexus 7 Original Development] bjcrj:
What min and max clock settings are you all using? I flashed with all default settings and it seems to like to stay at 370 for min mostly. Is it worth refreshing that as the min setting anyway?
[Nexus 7 Original Development] ximmox:
51 - 1300 MHz, undervolted -100mV.

The performance is amazing! Dennis, besten Dank! :thumbup:
[Nexus 7 Original Development] show-p1984:
Both.

That's normal.

g-mode (quadcore, power hog) goes from 370 - max.

lp-mode (low-power ninja core) from 51 - 475.

Depending on what you are doing (watching the freq for example) it might be enough to trigger the switch to g-mode / prevent the switch from g-mode to lp mode.

tegra_mpdecision has a hysteresis protection to prevent switches from/to lp mode that are only for a few ms. This avoids tiny micro-lags while switching between modes to affect performance (games/scrolling/etc). For the values see the 3rd post.

It also has an immediate switch from lp to g-mode if your governor requests any frequency higher than the max supported lp-mode frequency. (This kernel: 475Mhz).

So naturally you won't see the lp-mode much online while you are watching it, since that creates load. (Like the Weeping Angels it's sorta quantum locked :p)

tegra_mpdecision also enforces the lp-mode while the screen is offline as default (switches to gmode will not be allowed, should the soc do that on it's own for whatever reason we switch back to lp-mode immediately).

Yes, this kernel is something special. The score is not that high when you run quadrant. But who cares what score it gets when it's just so incredible smooth. Nice work Dennis!
[Nexus 7 Original Development] d0ge01:
Man , i ****ing love your kernel, is something exceptional about performance and battery but i have one issue...

There's one version ( zip or boot.img ) that don't require Aroma installer? Aroma installer each time finish installation stuck my device into black screen and i will force reboot
[Nexus 7 Original Development] show-p1984:
Install twrp, then you won't have any issues. :)

(Except that touchscreen doubletap to confirm aroma issue on the grouper)

I was just wondering why I had to press twice. Now I understand. :)

idk what i'm wrong but each time i press finish ( when install kernel , tried 3 times ) , nexus stuck on sod :/
[Nexus 7 Original Development] androidkid311:
Running this on tilipia, slim bean. I can't get the min frequency to stick on anything. Keeps jumping to 9100 as min when checking it using trickster.
[Nexus 7 Original Development] slebit:
Which version are you trying to flash?

---------- Post added at 10:52 PM ---------- Previous post was at 10:35 PM ----------

When you touch the screen it will go up to 910mhz. When you don't press the screen it will go back to your usual minimum frequency.
[Nexus 7 Original Development] dobbs69:
Same thing happened to me. After aroma finished, got a dead tablet. I plugged it into wall charger, nothing. I was holding the power button when I finally unplugged so not sure what caused it to come on but suddenly the google screen came on and all was good. I'm using 2.6 twrp also. Great kernel
[Nexus 7 Original Development] draggehn:
Is this JSS or JWR? Wanna use it on PA 3.97, which only supports JWR.
[Nexus 7 Original Development] show-p1984:
tilapia? grouper?

I think you confuse this with the mako. The n7 (2012) had no life changing kernel commits between JWR and JSS like the mako did.

This kernel will work on both just fine.
[Nexus 7 Original Development] draggehn:
Ohhhhh ok. My dad has mako, so is your mako version for JWR or JSS or does it not matter if he's not running a custom rom?

Thanks for your help, looking forward to flashing this soon.

Edit: does this not have swipe2wake or is that not possible for grouper?
[Nexus 7 Original Development] poondog:
Have a look into showp's mako kernel and ROM threads :)

No s2w atm on this kernel but there is one kernel that has it, which was ported from flo

Nice kernel show-p, very smooth and working like a boss! Seems like I have to enjoy my Grouper a few months longer before I purchase a Flo...
[Nexus 7 Original Development] poondog:
Aroma issue? I have had this happen a few times on grouper. It used to happen all the time on One because of the old aroma binary (there's a 2.70beta that fixes on One)

Usually if I rebooted with hardware combo the kernel wpould be installed no problem? I find that using the hardware power vol buttons to navigate in aroma somehow increases reliability

Why is everybody leaving :(
[Nexus 7 Original Development] Lazy Rich:
I have a question regarding GPU overclocking. Will it consume more power when I use 520 MHz instead of 484 when using the tablet for normal things like browsing, Tapatalk etc. or just when I play 3d games? Does the GPU have different modes for 2d/3d?

I like this kernel more and more. Battery life is getting better every charge I do. First charge I had around 4h screen on time, second I had 6h, and this charge is looking to be even better. Really nice work!
[Nexus 7 Original Development] ximmox:
To the ones that had problems with a black screen and unresponsive device after finishing the Aroma installer (like me, too), I think I might have found the cause: I just updated PA and flashed Bricked again, but did disable the screen timeout function in TWRP beforehand. Had no problems now and could return from Aroma to TWRP and reboot from there as usual.

My guess is, that TWRP doesn't count the Aroma installer as active task and the screen "times out in the background". So exiting Aroma = black, unresponsive screen.

Thanks for the kernel, running great so far.

Just one question to (a trickster setting which came with the last update) to GPU Fast Response: does a lower or higher value raise the frequency earlier? (or is it for a complete different thing).

Sorry for the maybe stupid question.
[Nexus 7 Original Development] tibere86:
Higher raises the frequency earlier.

---------- Post added at 05:13 PM ---------- Previous post was at 05:12 PM ----------

This is by far the fastest and smoothest kernel, thanks. My only issue is, with this kernel, my Nexus heats up like no other while watching Netflix or YouTube videos. Anyone else?
[Nexus 7 Original Development] Lazy Rich:
Can somebody answer this? :)

Gesendet von meinem Nexus 4 mit Tapatalk 4
[Nexus 7 Original Development] show-p1984:
I didn't answer this because this is common sense and hence does not require answering.

If you drive faster you need more gas and if you overclock something it draws more power.

The amount might be negligible here though.
[Nexus 7 Original Development] Lazy Rich:
Just thought there might be some 2d/ browsing mode in the GPU. So it runs at the desired frequency all the time? Than it is really common sense ;)

[Nexus 7 Original Development] show-p1984:
No it's scaling between different power levels.

But all of them are slightly risen in oc mode + it scales to max pretty quickly.

I'm not sure that it is a kernel problem, but this issue start from bricked kernel flash ( stable )

Sometimes my device spam 'shell' request on superuser and device become unusable because lag, and touch don't respond

You are triggering a bug report (iirc it was a vol down/up combination). That can be disabled in the ramdisk and is not kernel related.

Thanks for fast reply :) , i sospected it is related to volume keys issue solved :)
[Nexus 7 Original Development] ximmox:
Still an awesome kernel, but lately I noticed some weird "color gradient" issues I hadn't seen before. Once you noticed them, they can't be unseen.

Most visible they are on the blue Facebook app splash screen, but also when slowly pulling down the quick drawers, there they show on the background. Sadly the Screenshot functionality is too slow to grab a picture of the FB splash screen to directly show what I mean, but in general color gradients are not smooth and show very visible "steps".

If I remember correctly, the were also present in the stock kernel of the 4.3 PA versions, but I didn't have them with M-Kernel. I think someone mentioned that they were fixed in M-Kernel somehow, so maybe Dennis you could merge this fix into bricked, too?
[Nexus 7 Original Development] joshtb86:
flashed onto stock 4.3 and got stuck in a boot loop after first boot with most recent releease. reinstalls did not fix the problem.
[Nexus 7 Original Development] show-p1984:
"most recent release" and "stock 4.3" are far from accurate version descriptions. Also no last_kmsg was given.
[Nexus 7 Original Development] ximmox:
I looked into my request regarding the choppy gradients this evening and think I have found what is the difference in Metallice's M-Kernel.

He describes this feature/change as "Switch to higher quality dithering mode for better gradient quality (error diffusion)" , I looked through his github and this seems to be the corresponding commit: https://github.com/Metallice/android_kernel_grouper/commit/48a358a345c4051665e9a343807d0aa96f7053c0

Could you look into that Dennis or does anything speak against changing the dithering mode?

Or am I the only one bothered by the gradient quality? :confused:

Can't seem to get this kernel to run on my N7. I flashed the 0818 version. Went through Aroma with the default settings and my tablet just keeps booting to the Google screen and then restarting, even after the Aroma install completes successfully. Is there a more recent version for 4.3 CM ROMs?
[Nexus 7 Original Development] show-p1984:
This is also completely vague.

Which device? grouper/tilapia?

Which rom build version?

Most importantly: which kernel did you flash? There are 2 versions from August the 18th, a beta (20130818_161014_exp-f6d6ab2) and a stable (20130818_163259_master-5c316b9). Either just mention the hash (which is unique, even on a rebase with the exact same code), or write down the full uname -a or cat /proc/version.

Where is the last_kmsg with the failure of booting?

[Nexus 7 Original Development] ximmox:
Well, I only know that the gradients on M-Kernel look considerably better/smoother, also on bigger pictures like the Facebook splash screen (but I don't know if that might be stretched from a smaller image, if that is the 640px limitation).

Also that link is over 2 years old, way older than the grouper, couldn't it be that there were changes to that width limitation?
[Nexus 7 Original Development] show-p1984:
I didn't post that to express my negative feelings towards this change.

I will test it and see if it improves the situation without impacting performance, because lets face it, that tegra 3 has enough memory bottlenecks :p

I know I have been saying this before, but I can't say it enough. This kernel is running extremely well. Even after a couple of days uptime, it's still really solid.

I like to test kernels and this one has the highest performace... the only show-stopper for me is asphalt 8, its totally unplayable with this kernel, lags alot even at lowest settings... The game runs fine with other kernels.
