Yeah I was just thinking this morning how crazy it is that user experience varies soooo much with this tablet.

Would the variability between the nexus 7s make it difficult to make a kernel (even from scratch) that would work on all of them?

That's why I think there are different kernels. Like faux said no two chips are born equal and they all need special care :D
[Nexus 7 Original Development] osm0sis:
Franco has never used anything but the stock touch driver...

And on the contrary, I had the ghost touch problem with pinching to zoom and unzoom in Chrome on r62 and that's fixed in r64. It seems those who had problems with r62 are fixed now and those that didn't are broken.. :confused:
[Nexus 7 Original Development] mishko:
Was running stock for a while since I was getting issues with the older versions of this kernel. Returned to Franco with the release of r63. Now everything is great! Thumbs up!

I can also confirm that the touch on r62 was much better. Just went back to r62 and felt a significant improvement in touch sensitivity. Now back to enjoying my N7 with r62 :)

Thanks Franco for all your great work and efforts, I really hope you would find what causing then touch problems with r64

Cool mate, using on my mako and grouper with one week old, little baby ahah.

If you rebase, can you make channel like por mako like milestone, nightlies, etc. It's easier to browse.

As you know I build kernel based on your base for mako, and going to build also for grouper, top quality as always franco, thanks :highfive:

Just to point out how variable n7s can be, the touch response is better for me on r64. Go figure.

Personally I have no issues with mine, r63 touch screen was sometimes unresponsive when playing GTA vice city and I haven't been able to reproduce it in r64. For me r64 is giving fantastic battery life and great performance, in fact I'm probably going to lower hispeed freq and increase high load threshold to 65-70 on next battery cycle.

no games, but my keyboard would become unresponsive in landscape mode, i believe on r63 (possibly r62 can't remember). either way, the issue has not presented itself again since flashing r64

I tried Franco's battery saving settings back on post #7098 and I can't seem to find any performance hiccups as if it were on stock settings. Very good! :good:
[Nexus 7 Original Development] franciscofranco:
Don't even get me started on that... On Mako is the same crap with all that "soc" thing. Saddens me that people don't even know that SoC means System-on-Chip, but they go all "I've set my soc to C2 and amg it crashed". C-states are Power States for the cpus they are scaled either via cpuidle menu governor or a specific vendor implementation. I like when they say that using C1 or C2 crashed their devices, but they don't even bother to go read CAF's commit messages explaining how how states working on Mako's APQ8064 and how broken it is.

Well enough rant, it would rain hell if I wrote this on my Mako thread :)

Lets talk business. Today I've been working a bit on Interactive again and got to some nice things. I don't really want to go into details because I've wrote about it on my commit message, so check git to read them! And I've added a small change on the load calculator which now takes into account iowait time as non-idle time. When the device is waiting for IO means that its active and not idle, so during idle calculation time the iowait time should be subtraced from the idle time. This will improve performance during high IO peak times since the Hotplug driver will most likely online all cores to compensate for the busy time.

I also reverted a probably-problematic patch which "should" fix all those utorrent hard reboots. Let me know if they still happen.

Oh and hai r65, couldn't help it! Uploading now!

Yes, same here, I am on r65 now, and changed Hotplug driver first_level threshold to 80 and also decreased input_boost_freq and hispeed_freq to 760MHz. Don't notice much of a difference, still pretty smooth.
[Nexus 7 Original Development] MarthaFokker:
I was on r47 before upgrading to r61 and I just noticed that I can't mount my thumb drive using a usb otg cable. I flashed r47 just to test and it seems to work fine on that kernel. I've since tried r62 and r64 too and they all can't seem to mount a thumb drive off a otg cable. I am on PA-3.6 rom by the way.

Hi all,

i just encountered a strange issue.

I am on R65.

I just copied some Files from my Laptop to my N7 and it was super responding until the copy started.

It was laggy as hell, and took 10 secodns to open the app drawer for example.

i can easily reproduce the issues.

btw. N7 responded super fast as soon as the transfer ended... maybe something wrong with the new IO algorithm?

attached Last:Kmesg, DMESG, dunno if it is anyhow usefull

I still find r62 the fastest and most touch friendly. Must be some incompatibility between the newer versions and cm 10.1

Is the default scheduler ROW? Because in the r64 changelog it says that it has changed to ROW but when I clear the app data or use the emergency kernel reset.zip it stays at deadline.

Same here.
[Nexus 7 Original Development] Bobtehblob:
I figured out what's causing the lock up on wake. If I have wifi set to turn off on sleep then it locks upon wake. Doesn't happen if wifi is kept on. I'm on cm10.1 does this happen to you guys on stock? Not sure if it's a Dom issue or not.
[Nexus 7 Original Development] fgenari:
I have to agree....r62 is the best kernel for cm10.1 ROMs....

N7 is another device with him...

I tried r63, r64 and now r65....r64 is the best of them.( in my opinion)

But r62, I don't know why, is perfect...very smooth, touch response and faster.

Nice job on r65, touch seems better and it is butter smooth.
[Nexus 7 Original Development] MarthaFokker:
I'm back on r47 because all the r6x kernels I've tried had a weird delay on touch response.

I would put my finger on the screen to scroll and my finger travels 1.5 to 2.0 inches before the page or screen starts scrolling. After that, if i don't take my finger off the screen after the page/screen has started scrolling, there is no delay if i scroll back and forth. As soon as i take my finger off the screen and try to scroll again, same the same thing happens all over again. Happens when scrolling between home screens on nova launcher and web pages on various browsers. It even happens on the xda app.

I also have to hit a link/button 2 or 3 times before a touch registers
[Nexus 7 Original Development] osm0sis:
Did we discover those having issues have Trebuchet in common? Does that still seem to be the case?
[Nexus 7 Original Development] why always me:
r62 is the best for me here on Rasbeanjelly and Purity too.
[Nexus 7 Original Development] Timo_SGS2:
Thanks for the hint, forgot about the scheduler in this moment.

Scheduler that had somehow trouble was deadline...

changed to row, and copying the same data / and other data, and the issues is still persistens...

couldn´t resist myself... flashed emergency reset script and R63 in top, and cleared franco kernal app settings...

copied same data once more, and i have this lag as well... change scheduler from deadline(default) to row while copiyng, but on both it stutters like hell...

right after transfer is finished, system is running flawlessly again...

somehow strange

Nevertheless, i don´t copy that much data onto my N7, and therefore Franco is still the best kernel :)

Btw. I am running Nova Prime not trebuchet...
[Nexus 7 Original Development] osm0sis:
row = read over write, so yeah, I wouldn't expect choking from writes to improve there.. Try cfq. Also, please go to my odds and ends thread and grab settingsdump.sh and pastie the output file. I want to know if we're dealing with ROM interference here.

I am on r65 and it seems Wi-Fi doesn't turn off anymore when the tablet is sleeping. My setting is to only keep Wi-Fi on when tablet plugged in, so maybe the sleep state doesn't get reported correctly. Anybody else notice that?

---------- Post added at 08:20 AM ---------- Previous post was at 08:17 AM ----------

Noticed the same thing on mine when doing large installs from the app store. It becomes almost unusable until the install is complete. R61 and prior versions didn't have this issue.
[Nexus 7 Original Development] osm0sis:
Nothing changed with io from r5x to r6x.
[Nexus 7 Original Development] sjknight413:
Sorry to say it again Franco, i know i'm not being at all helpful but r65 is worse than r64 was for me. I honestly cannot scroll past my first homescreen because it keeps flicking back.

What changed from r62 to r63 that could have affected me so much? Everything was super responsive on r62 and past that my tablet becomes the most unresponsive i have ever seen it.

I want to stick with r62 but the problem with that is only get 3 and a half hours screen on time which is really bad, thats with the hispeed freq set at 760mhz!
[Nexus 7 Original Development] yukkio:
Hi, here with r65 with uv,hi speed freq at 760 and hotplug at 90. No problems with speed but I have 1.2h sot and 60% of battery left.

I love the speed of this kernel but I think there is a battery problem.

[Nexus 7 Original Development] poondog:
If you only just flashed it, the battery reading won't be very accurate. Give it a few days :)
[Nexus 7 Original Development] mpokwsths:
The good thing is that there is a kernel version for everyone.

r62 for many is the most touch responsive kernel ever and r64/65 for the rest.

Everyone is happy, except, maybe, Franco who cannot figure out WTF is happening and what changed between r62 and r64 that changed the touchscreen behavior...
[Nexus 7 Original Development] yukkio:
I flashed r62 a few days ago. I will try to drain battery to 0% and then I will see if the problem is gone.

Thanks.

[Nexus 7 Original Development] Kaiyes:
R65.... The torrent issue is gone. At least when not on overnight charge. I downloaded torrent while it wasn't plugged in for charging and screen was off/locked. The torrent downloaded fine !!!!!! Tonight I will try with the combination that always reproduced the torrent problem. The combination:

1. Plug in for over night charge.

2 start downloading a torrent .

3. Either screen off(will try tonight; froze tab everytime)/screen on (try tomorrow; froze tab some times).

Today is the first day that it downloaded the full thing while screen was off (locked) which is a pleasure. Thank you so much Franco. I believe the torrent patch worked.

Edit: no need to test with screen on, that was a painful work around as screen off downloading + charge caused freezing. But if screen off works, no need for that. It will be plain foolish.

Just flashed r65 a couple hours ago. Initial impressions are super snappy and smooth with excellent touch response. The best kernel I have used yet for my N7. Here's hoping battery life is decent (rarely do you get it all in life, let alone a kernel).

[Nexus 7 Original Development] sjknight413:
So do you think that's good or bad?

Because that is really bad battery life.
[Nexus 7 Original Development] Krayvon:
!

i think he was making a statement. period.:p
[Nexus 7 Original Development] Gspin96:
I think it's bad. But it looks to me like the battery life has been decreasing since I bought the device (6 months ago). I don't get better battery life on CM kernel.

Also, my nexus 7 is the 3g version (it was the only available in stores when I bought it, otherwise I'd have gone with the 32GB WiFi), and altohugh there's NO SIM inserted and it's permanently on airplane mode, on the battery graph I see some (little) lines indicating that it caught network signal. So, I think that the 3g module is draining my battery while it should be turned off. I attach screenshots.

Now on r65, changed high load threshold in hotplug settings to 80, and lowered input boost and highload frequency to 740MHz. Will charge overnight (=12 hours from now) and check the next discharge.
[Nexus 7 Original Development] konradsa:
Drad... just had another instance of the tablet being locked into low cpu speed with r65. :( Strangely, even though it was stuck in low speed, it seemed to have drained my better completely. It was 95% when I left this morning, and when I came home it was stuck in low speed and down to 15%, even though it had been sleeping all day and nobody was using it.

Think I am going back to r47 again. That version is still the benchmark in terms of stability, battery life, and responsiveness.

True, I have random restarts on r47, but still better than pulling your tablet out of your pocket before a 2 hour bus ride and find out your battery has been completely drained while sleeping.

R65 it's great, if not for battery and stability issues. R65 performance in a stable kernel would be perfect though.

HAHAHHAHA

On another note, I wanted to see if someone could recreate an issue I've been having using the following things:

RootBox 06.21.2013

20130301 Gapps (not that the gapps should matter with this issue)

Franco Kernel r65 (flashed via Franco App

Poweramp (I'm using the Pro version, whether that makes a difference with this issue, I'm not sure)

Listen to music via A2DP

While streaming music in my car with A2DP, the music is VERY choppy, it isn't even "listenable". I think the longest music played without skipping/chopping was about 3 seconds. I reflashed the ROM to get the RootBox kernel back on, and everything went back to streaming just fine, therefore, it seems to be related to the kernel if i'm not mistaken (i mean, changing kernels fixed it IMMEDIATELY)

Can anyone else confirm this, and does anyone know what I can tweak regarding the kernel to prevent this from happening?

I have a question, been using this kernel for about 2 weeks, progressing through the changes. PACman rom. Not having a real problem with anything really other then when streaming audio through Play. I expect it's more a tweak rather than an issue with the kernel because I had the same issue with the he previous kernel. It works perfect while the screen is on. Once I let it fall asleep or do it with the power button it always happens. Anybody else notice periodic popping when streaming? I toggled the Wifi PM_Fast back and forth between testing the different governors and schedulers trying to fine something that works, still popping. What settings are people doing using?

Thanks in advance.

[Nexus 7 Original Development] konradsa:
Ok, so it happened again this morning, where the tablet was stuck in low speed. This time it happened when I was charging overnight.

I suspect it has something to do with the Wi-Fi settings. It wasn't happening before I changed the setting under "Advanced" - "Keep Wi-Fi on during sleep" to "Never". It also seems to be caused by wpa_supplicant.

Can someone else confirm that this causes the problem? You may have to wait a day or two after changing the setting until the problem occurs.
