I've has the same rom for a while.

No wake problems with other kernels

Randomly I had like ten second wake times with the thalamus driver in r47 (Franco's modded one)

Then with r48 took two seconds to turn on every time

Now it's fine :)

I do think it's related to thalamus hot plug from my experience
[Nexus 7 Original Development] franciscofranco:
I have no idea what is that frandom module.

I'm very happy with the results from this new driver, Mako users are also happy :)
[Nexus 7 Original Development] arhung:
I think the battery life with r52 is very bad, with the same setting in Franco's app but now I got 66%left with 3.5hr unplug and about 2hr screen on time.

p.s I still get lag with r52.
[Nexus 7 Original Development] zaclimon:
Here's some info about frandom:

[Nexus 7 Original Development] franciscofranco:
Nothing in Android uses urandom or any of that entropy ****, a Google engineer explained that himself in one of the Google groups some months ago, so I don't see a reason to include such thing. Why would you need that though?
[Nexus 7 Original Development] keyra74:
R52, no more delay in wake up for me, i'll check more later
[Nexus 7 Original Development] LOVE ME PLEASE:
There is completely no onscreen delay :) thanks Franco!
[Nexus 7 Original Development] Twau:
Thanks for updating the N7 Franco, r52 works really good so far, not had a single slowdown yet. Could reproduce this quite fast with the r50 build using Chrome.
[Nexus 7 Original Development] MaNFr3:
Anyone could post me cpu/governor configuration for a good battery life?

[Nexus 7 Original Development] poondog:
The best balance from our testing over a long time has been found and posted

They are what Franco includes stock :) obviously it can be tuned for more battery, you could start be lowering the High-speed freq

I'd keep it stock though, its good enough for most people :)
[Nexus 7 Original Development] k29er:
Getting random temporary freezes when streaming with r52. No other problems.

So smooth it almost makes xda scrolling smooth.

Edit: spoke too soon, xda just fc.
[Nexus 7 Original Development] osm0sis:
Streaming what and how? Please be specific so Francisco can try and recreate and improve further.
[Nexus 7 Original Development] LOVE ME PLEASE:
I think he's talking about video streaming. I have T1 speed and as I was playing a few YouTube videos, I came across a lot of video lag. Other than that, kernel is beastly!
[Nexus 7 Original Development] osm0sis:
A link to the specific (HD I assume) videos then would probably help. :)

I did some streaming with some reasonably lengthy YouTube vids yesterday and had no problems.
[Nexus 7 Original Development] Shano56:
A single fc is probably your apps fault. Happens occasionally
[Nexus 7 Original Development] franciscofranco:
I just tried and I found no lag or slowdowns in Youtube videos using Youtube app. There is obviously still room for improvement though, but now with the Hotplug driver ported from Mako I can sync the changes on both platforms easily!
[Nexus 7 Original Development] k29er:
Streaming netflicks. Tried again and it fc. Then again tried it with ondemand and it froze needing a hard reset. Then I tried conservative, boot was OK but xda launch said search disabled so I gave up and put it to sleep. Ten minutes later I looked at it and xda had launch itself and was holding the screen on. I have it set to sleep after two minutes. Francos was the kernel I used the most up to r38 because battery life is important to me. I retry it every new release since the smoother setting came about but battery is no better than what most ROMs come with now. I have purchased all the dev's apps and try most when there is a new release. If I am the only one having problems I don't send crash info, if it does not work I move on.
[Nexus 7 Original Development] franciscofranco:
Force closes have nothing to do with the kernel :crying:

Everything you described is rom/app business!
[Nexus 7 Original Development] LOVE ME PLEASE:
Sorry Franco, I rebooted the system and tried again and everything is perfect. I should've knew that YouTube can be a little funny on speeds at times.:confused:
[Nexus 7 Original Development] GedBlake:
Having problems with r52... in YouTube, iMDB (movie trailers), BBC iPlayer, ITV Player - a sort of transient (comes and goes; sometimes, just touching the screen smooths everything out) 'staccato' lag... like a broken microphone or failure to buffer correctly.

Switching to 'on demand' fixes it.

Back on r47... and everything is golden again. Rock solid and stable... and very smooth.

-------

r52 is great in all other regards... smooth and fast... Temple Run 2 runs great. BUT... there's still something not quite right with it. It's difficult to nail down the specifics...

-------

Anyway, just some feedback - absolutely no criticism intended.

Rgrds,

Ged.
[Nexus 7 Original Development] quadracin42:
I tried the r52 it works fine until you lock the screen and come back to use it lags real bad and screen tearing. I tried using a reset kernel from faux and still the same thing. I'm i missing a step?

Thank you
[Nexus 7 Original Development] xonone:
try to use the kernel wipe script. it works pretty well on most roms. On PA I had to alteast try a few times for a full wipe for some reason.

[Nexus 7 Original Development] k29er:
Then I am using the wrong term.

I use my nexus 5-8 hours a day using all aspects of it, streaming, ereading , lots of news/rss reading, podcast listening with Bluetooth, gaming, surfing and even navigating so I know how it works. I don't flash ROMs frequently anymore and do a full wipe install when I do. I have run this current ROM(Carbon) with no updates or dirty flashes for over two weeks so that's well over 60 hours of use with no problems.

You say my problems are ROM,app related but they only happened when I installed r52. I tried it yesterday and it felt great but after a half hour problems started. I uninstalled it and everything was fine for the next hour. In tried it again today and could not get it to work well. I uninstalled and has been fine since.

Again if I'm the only one having problems I will move on.

Not complaining just trying things out and giving my results.
[Nexus 7 Original Development] quadracin42:
Where can I find the script i looked and searched don't see it. Sorry if I'm just blind :rolleyes:

I'm getting quite a delay from the time I hit the power button until the screen comes on with R52.
[Nexus 7 Original Development] osm0sis:
With a random single attempt or with multiple rapid fire off-on's? The latter will do that anyway.
[Nexus 7 Original Development] The Gingerbread Man:
This thread is getting funny, some loving the update and others still reporting bugs which others are claiming to be fixed (screen on lag in particular). Those who think they are facing screen on lag please see if it helps removing 3rd party lock screen widgets and clear Franco app data and reflash r52. Personally I have no problems here running stock 4.2.2 rooted.

Sounds good to me, I think people think people on a whole think this device progress is moving slowly and it would be good to show **** is being done and the stuff from "the other place" shows its not just most of it is behind the scenes at the moment
[Nexus 7 Original Development] NoobieExtraordinare:
Went back to trinity. Couldn't stand the lag and lockscreen delay. battery was also draining pretty quick. Will come back to this once things are a bit more stable. However I love the features of Francos app over the Trinity toolbox app.
[Nexus 7 Original Development] farmerbb:
On r52 today, my Nexus 7 was stuck on single core at 102mhz for about 5-10 minutes or so before it resumed hotplugging normally.

kmsg attached, it if will help diagnose this issue.

Interesting! I wonder what the actual problem was. Glad it works for you now. :)
[Nexus 7 Original Development] airmaxx23:
This is after waiting about a minute or more and then one single turn on. Even if it sits for a while there is a delay when turning the screen on.

Edit: It's still there on R53.
[Nexus 7 Original Development] franciscofranco:
I have stock rom and I cannot reproduce that as much as I try!!!

What kind of delay are we talking about? 1 second? 2 second? 10 hours?
[Nexus 7 Original Development] Grakel:
Instant wakeups on aokp pub ;)
[Nexus 7 Original Development] Twau:
I can't reproduce that unlock screen delay with r53 either, you should try to fastboot the factory system.img and then flash r53 again to see if that helps.

I used to get that on like every ROM with thalamus

Can safely say that *so far* this hasn't occurred with the new hotplug, although I haven't updated to 53

[Nexus 7 Original Development] sjknight413:
R53 is a winner here. Your new hotplug is certainly smoother :)

Battery life still seems really bad though, currently on 66% after an hour and thirty seven minutes screen on time.
[Nexus 7 Original Development] airmaxx23:
A second and a half, it isn't there with m- kernel, I'll flash r47 and see how it goes. I'm on xenon ROM.
[Nexus 7 Original Development] osm0sis:
Give it a full cycle first maybe.
[Nexus 7 Original Development] sjknight413:
Yeah I'll do that anyway but it never makes a difference. I did give r52 a full cycle and the battery life was still awful.
[Nexus 7 Original Development] airmaxx23:
There is no delay on r47, I'll flash r48 and see if its present there or not.
[Nexus 7 Original Development] formicae:
With just a megabit and a half, I'm surprised you don't see video lag all the time. If I remember correctly, YouTube uses just over 2 megabits per second just for 720p.

Check for wakelocks using BetterBatteryStats or Wakelock Detector, that seems fishy. I flashed r52 about nine hours ago with about 96% battery, went out for about eight hours and it's at 93%.
[Nexus 7 Original Development] franciscofranco:
Lets give it a few cycles for battery life. I'll use my N7 a bit more to get some data.
[Nexus 7 Original Development] k29er:
On r53. Getting small freezes in netflicks after pausing. Its very smooth at start and if I exit and restart but if I pause for any time it will not resume smooth play. I have not tried any games but everything else is good now.

I was just asking if he says no I will continue to use his kernel as I have been

Sent from my Epic Touch armed with a Jellybean army to kill you Apple!
[Nexus 7 Original Development] The Gingerbread Man:
It probably will take 2-3 cycles for your battery stats to recalibrate, don't expect instant results in terms of battery, you should how ever find performce boost straight away. May as well use r53 as its newest build.

Don't both r48 is quite out dated already use latest r53

Probably an app issue with netflicks, see if westwood TCP helps with this as generally internet speed is increased using it
[Nexus 7 Original Development] sjknight413:
Like i said, it never makes a difference, battery stats calibration is a myth. As long as you flash the kernel at full battery it will be absolutely fine.

With stock cm kernel I get six hours screen on with the first run, m kernel I always get around seven hours upon first run and with franco's I get around the four- four and a half hour mark every time.

Performance is great however :)
[Nexus 7 Original Development] The Gingerbread Man:
Going by my battery stats im set for pretty good battery life, probably more than 4 hours. In my screen shots you can even see when I flashed r53

Sent from my Galaxy Nexus
[Nexus 7 Original Development] sjknight413:
Between four and five hours isn't good battery life though, especially for a nexus 7.

7 hours is roughly what could be quantified as good battery life.
[Nexus 7 Original Development] osm0sis:
Okay now that we're running a smoother hotplug driver, those with battery complaints could try these sightly less aggressive interactive governor tunables based on what we came up with for winners on the GN: 15000 / 95 / 760MHz / 45000 / 30000 / 85.

Seem to be working very nicely here.

If you read my stats again youl see I'm already over 2 hour screen on with 63% battery left and that's with flashing a kernel at no where near 100% battery.

[Nexus 7 Original Development] farmerbb:
I'm still getting these random slowdowns where I'll be stuck on only one core at 102mhz... is anyone else still having these? On r53 with 100% default kernel settings.

Not quite sure how to reproduce this, it just seems to come through normal usage. This time, it started shortly after I loaded up the Play Store, lasted for about a minute or so before I turned the screen off/on which fixed it. Rebooted the device shortly thereafter to grab the last_kmsg.
[Nexus 7 Original Development] franciscofranco:
That is so weird, I can't reproduce at all. We'll see about r54, I cleaned up the Hotplug driver: https://github.com/franciscofranco/mako/commit/d39d8d44005117ef63ba8e7c827615ac48a89707 maybe I squashed bugs in the process.

[Nexus 7 Original Development] sjknight413:
Franco, just to let you know the system monitor in your app seems to be a bit useless as drawing the graph itself causes the CPU usage to stay at around 15-20% thus making the frequency stay at around 760mhz and up whilst the graph is running. When I use your other simpler monitor panel the frequency stays at 102mhz because it isn't in use.
[Nexus 7 Original Development] scottx .:
Been using your kernel for a long time. First on my GSM gnex and now on both 4 & 7. Bought the paid app last night and I'm glad I did.

Keep up the good work!

The gpu on the n7 isn't configurable with colors and such like the other devices, and never will be? I'd like it and I'm sure if you could you would. Must not be possible.

"Maybe its time for an upgrade" haha. If I was testing a nook color does it tell me to set it on fire? Because this tablet is not slow by any means.

[Nexus 7 Original Development] franciscofranco:
I might have found out why theres some weird **** when turning the screen on. Theres a bunch of stuff being done by NVIDIA when the screen goes on/off that is related to their autohotplug drivers and some other weird routines. I'm cleaning it up which should clear out most problems... its an utter mess. Just check arch/arm/mach-tegra/cpu-tegra.c and rejoice.
[Nexus 7 Original Development] franciscofranco:
Pushing r55:

* Sync the hotplug driver cleanup from Mako - routines are the same, just cleaned up for upstream Kernel standards

* Updated interactive winning values - thanks guys

* Cleaned up some Tegra drivers: cleanup suspend/resume mess, remove useless functions that capspeeds for edp and other clocks, tweak the power states latency residency, make sure the device enters LP0 on suspend. Hope nothing major breaks with this

* Fix https://code.google.com/p/android/issues/detail?id=42993
