[Nexus 7 Original Development] Thvmh:
Isn't it something to use the low activety cpu too support it by high load on the other cpu's so the load is lower overall. As franco says that it is maybe just a underclocked normal cpu?

[Nexus 7 Original Development] slybunda:
nop its not just underclocked, its built on a different process to have less leakage so its more efficient.
[Nexus 7 Original Development] sshädow:
This is an application problem. My Nexus 7 is in general very smooth and responsive, however the Engadget app does take forever to load up and become responsive. Using System Monitor I can see that there is almost no disk I/O, only a very small spike right when starting. 98 % of the loading time is spent on CPU, where one core just sits at 1,2 ghz and under full load. So the issue is not related to memory, trim, or anything like that in this case. The app is just useless and hangs for some reason.
[Nexus 7 Original Development] khaytsus:
Facepalm.....

Except that it doesn't happen on everyone's N7, and it loads in less than 5s on my Galaxy Note. So badly designed app, cool, but why does it take over a minute on my N7, 5s on my phone, and very fast on some N7's? Just bugs me, I routinely used this app 3-4 times a day, maybe more when something is going on, and since 4.3 it's useless on the N7. Oh well.
[Nexus 7 Original Development] sshädow:
It is probably just some kind of random bug. Things like that happens, the best you can do is send a report when the app hangs.
[Nexus 7 Original Development] khaytsus:
It'd be nice if it were random, it's 100% reproducible. Or I wouldn't have mentioned it ;) Anyway, way off topic in francos kernel thread.

I just noticed a little issue with r65:

Every time I put my N7 into standby by pressing the power button the played sound stutters a little. This happens with Spotify and with BeyondPod.

Going back to the CM kernel solved this issue!

I was using both kernels (CM kernel and r65) with the default config.
[Nexus 7 Original Development] khaytsus:
Already is brilliant..

dear francisco i have a big questions,i use your r65 kernel on my nexus 7 with aospa 3+ android 4.2.2,now the paranoidandroid team have update the rom to android 4.3,your kernel r65 is compatible? or i have a problem if install it? i expect if you compiling a new kernel for android 4.3? thanks for your great job and sorry for my bad english,with maximum respect

There is a r70 nightly working fine on 4.3, but you have to flash it via fastboot.
[Nexus 7 Original Development] galaningenieros:
Or use flashify :)
[Nexus 7 Original Development] peneoark:
Ive never heard of that. I just made a flashable zip lol
[Nexus 7 Original Development] NYLimited:
I am not certain but the N7 charges *much* faster in the docking station or with direct AC plugin. My car charger is quite powerful and I use the charge only (shorted) cable but if the screen is on charge is slowly decreasing. Not so in the docking station.

So, I don't know the answer but it is puzzling.

[Nexus 7 Original Development] stranger97:
Sorry man i was in a hurry so didnt notice anyways thanks
[Nexus 7 Original Development] bsoplinger:
That's why I keep the fsync_on zip handy and immediately flash it after flashing a new kernel. Which is also why I flash kernel updates manually. I don't get many, if any, random reboots or device crashes but I do get the occasional "phantom reboot" where the device appears to reboot but in actuality only the Android interface died. But that's still enough to stop apps and cause data loss.

[Nexus 7 Original Development] slybunda:
Also I noticed I get poor standby battery life with r70 on stock 4.3, deep sleep is not working, how do I fix that or is the kernel just bugged still?

---------- Post added at 11:58 PM ---------- Previous post was at 11:43 PM ----------

franco: I was wondering, I know you have mentioned before that the low power companion core is not worth using, but would it make a difference if for example, when the screen is off have the cpu limited to 475mhz and let it use companion core only, so things like notifications/message checking, mp3 playing etc can be done off the single low power core.

and when screen is turned back on have it stick back over to the regular quad core cluster and resume as normal?

this way the companion core will only be used when screen is off.

also I have tried turning off wifi, and still deep sleep is not working meaning Im getting a drain of 1% per hour on standby, when before on stock 4.3 kernel I was using like 2% overnight.
[Nexus 7 Original Development] franciscofranco:
Just released the first nightly r75. It contains everything but GPU OC and UV interfaces. Also fully compatible with CM and derivates. Theres quite some changes since r70 that I pushed out as a test a week ago. Have fun!
[Nexus 7 Original Development] icu64:
Is there a place that shows the changes and features that you have in your kernel other than the op? Its not as descriptive as I would like... Hope I'm not being annoying I'm just curious :-\
[Nexus 7 Original Development] franciscofranco:
github link in the OP has all the commits I pushed.
[Nexus 7 Original Development] icu64:
OK thanks, I'm not to familiar with how it works but I'll look and learn. Thanks for the response! XD
[Nexus 7 Original Development] kevin0164:
Just auto-flash the r75-nightly with FKU on my stock-4.3 nexus 7 16GB.

After re-boot, the supersu poped up a notification that "There is no SU binary installed and SuperSU cannot install it. This is a problem!".

This issue is solved after I re-flash the current latest UPDATE-SuperSU-v1.51.zip with CWM.

It's butter-smoothy now. Great work and thanks Franco !!
[Nexus 7 Original Development] gpzbc:

the 4.3 ota update fails for me on my nexus 7 wifi...i tried to install the update with twrp recovery...i am on rooted stock 4.2.2 rom and i flashed the stock 4.2.2 kernel for the update...the only thing i did was flashing francos kernel...all other is/was stock.the problem seems do be a power.grouper.so file in lib/hw folder...does anybody can upload the stock file for me so i can replace that file with the stock power.grouper.so file for 4.2.2 nexus 7 wifi?

Edit:

I searched in my lib/hw folder but i didn't find that file...i only have a power.default.so file...is that the same file so i can rename it to power.grouper.so?
[Nexus 7 Original Development] blipp:
I suggest just getting the factory image from googles site and flash it via a Toolkit or however else people do it if the ota isn't working. Itll probably run better from a fresh 4.3 install anyway.
[Nexus 7 Original Development] eng.stk:
Hey franco, smoothy smooth as always :highfive:

Can you commit that sysfs entries please?

This is almost at 4.2.2 stage, nice work. Only GPU OC, UV (this is very important for most of us, squeeze that bat:p) and the hotplug sysfs

[Nexus 7 Original Development] sjknight413:
R75 and cm10.2 combined gave me some of the worst lag I have ever experienced on my nexus 7, I wish there was a way to go back to r62 level smoothness on 4.3. The touch was so much more responsive with no lag or stuttering to be found.

For now I guess I'm stuck on cm10.1
[Nexus 7 Original Development] pit84:
new r75 for android 4.3 is supported by the apps?
[Nexus 7 Original Development] why always me:
Exactly the same feeling here with r75, here on my device r70 is somehow even better than r75.
[Nexus 7 Original Development] franciscofranco:
O.o

That is a bit impossible, when you touch the device it ramps up to max frequency while you're touching it, its impossible to have lag in that scenario unless the rom is ****ing something up. Unless you can reproduce lag on stock rom there is nothing I can and will do because on stock it works just great.
[Nexus 7 Original Development] jfmcbrayer:
I had to re-flash SuperSU (was already at 1.51), but other than that r75 is so-far, so-good. Will undervolt when available, but I'm not missing GPU overclock, since my GPU doesn't tolerate overclocking very well.
[Nexus 7 Original Development] sjknight413:
Okay I'm going to backup up everything now and flash stock 4.3 in that case, let's see if it fares any better :)
[Nexus 7 Original Development] jfmcbrayer:
Oh, one thing I just noticed that is not so great (but honestly pretty trivial) is that the interface used by CurrentWidget to get charging values hasn't been added back yet in r75.
[Nexus 7 Original Development] why always me:
My bad maybe rom it self like you're said I was using r70 on fresh stock rom and r75 on dirty PA(flash r75 over some other kernel).
[Nexus 7 Original Development] sjknight413:
Still exactly the same behaviour with r75 on totally stock 4.3, honestly it renders my device almost unuseable! homescreens become really sticky and scrolling through any sort of list is an absolute chore.
[Nexus 7 Original Development] igerup:
Is it just a 4.3 thing that root gets disabled when we flash r75? Not that it matters much to anyone in this thread, seeing as we all have a custom recovery installed. Well, I hope we all have:)

Anyway, it's nice to have a 4.3 kernel available so soon after the source was made public. Thanks for all your coding/compiling everyone.

[Nexus 7 Original Development] zPacKRat:
Same here on the Engadget app, most likely due to changes in 4.3

Sad thing is they are slow to update the app.
[Nexus 7 Original Development] khaytsus:
Yeah I think the app is just badly designed, maybe they did some poor programming. Market comments agree that it is a mess on 4.3 on all devices.
[Nexus 7 Original Development] jfmcbrayer:
On r75, what's the GPU frequency set to? I ask, because my device doesn't seem to like any frequency above 416 (stock) -- I've tried on various 4.2 kernels (Motley, M-Kernel, franco, faux), and after about 12 hours, I start getting media stuttering and slow scrolling that persists until I reboot.I can happily use franco.Kernel as long as I can set the GPU frequency back down to stock. But with r75, I got the problem after 12 hours or so. So I guess that we don't have the GPU overclocking interface yet, but that it's currently hardcoded to 446 or something (that's reasonable for most people, but not for me)?
[Nexus 7 Original Development] franciscofranco:
GPU frequency is stock, I havent messed with it. The drivers are also stock so I dunno.
[Nexus 7 Original Development] combatdeity:
Are you planning on reintroducing GPU over clock to the kernel?
[Nexus 7 Original Development] jfmcbrayer:
Huh. My theory about what's happening is most likely wrong, then. I was working from _motley's theory (at the bottom of this post), and always setting the GPU max speed back down to 416 was working for me with the 4.2 franco and motley kernels. But if the GPU frequency in r75 is stock, it must be something else happening. It's not exactly reliably testable, so all I can say is that my device is vaguely flaky, and slightly more flaky on any kernels other than stock. Which makes no sense, I know.

Compared to stock kernel, since r63 I don't have a good battery life with this kernel. I get drain by simply reading (like 2% on 5 minutes)

I will say that reading books on nexus 7 drains battery more on franco kernel than stock kernel, this is expected though due to franco having 2 cores active all the time and stock uses the low power core.

It seems the SU daemon was not started on franco kernel. I preceeded to fastboot flash back stock kernel and i got root access again.
[Nexus 7 Original Development] Z23:
You flashed SuperSU v1.51? Older versions won't work!
[Nexus 7 Original Development] bsoplinger:
I don't know if Chainfire changed the OP for SuperSU but the latest versions, those usable with 4.3, require you to correctly answer the question about disabling (or was it replacing) custom recovery. If you answer the wrong way it seems like you've installed and rooted but you haven't and you'll get the errors about root not installed. If this is what happened to you just flash again and answer the question correctly. I don't remember the specifics of the question unfortunately but hopefully I've put enough here to help.

[Nexus 7 Original Development] osm0sis:
Actually it doesn't matter what you select because Chainfire chattr +i'd /system/etc/install-recovery.sh making it unable to be deleted by any method until it has -i applied, and either way f.K shouldn't require that file since daemonsu should be running as a native service called from one of the init.*.rc files.

I did just fix up some stuff in init.superuser.rc yesterday with the GN, so maybe that needs some work over here too. I'll check it out early next week if [MENTION=3292224]franciscofranco[/MENTION] doesn't beat me to it.

By the way you can make that warning/question in CWM 6.0.3.5+ go away by creating an empty file at /system/etc/.installed_su_daemon :good:

Hopefully Chainfire adds that to his zip in the future.

:)

Edit: Yup, r75 has root problems if you delete the init.d script SuperSU v1.51 installs. Here's the command that needs to be in an init.d script to maintain root until this gets fixed:
