Possible resolution for Netflix problem.

Here is what I just observed. I decided to clear caches and reflash Revolver 4.0.3 RC3 and Revolver Removed Apps and reflashed the version 21.11 build 607 kernel. I decided NOT to reflash the new nvidia codecs and also didn't reflash DSP Manager. After reboot, I just finished watching over 2 solid hours of Netflix videos without a hitch nor any noticeable artifacts. So, I think I can conclude that the problem was introduced either by the new nvidia codecs or DSP Manager. I will reboot later and observe some more to be sure and maybe test reintroducing one of the components at a time to see which causes the problem to re-emerge. Version 21.11 build 607 seems pretty snappy and stable now, so far.
[Eee Pad Transformer Android Development] DROITURK182:
my USB and micro and standard SD cards work fine on 21.11 kernel with ASUS stock ROM with enhancements, if you are having trouble with yours I would flash again but make sure to wipe cache and Dalvik cache.
[Eee Pad Transformer Android Development] AllanJacques:
Where did you find new nvidia codecs? Thanks a lot!
[Eee Pad Transformer Android Development] gideo:
There is a link on the first page

tnx!!!
[Eee Pad Transformer Android Development] pyro254750:
So far 21.11 is stable, no sods or rr and battery life is great, especially in deep sleep. I put very little time into the tf at work today, it was asleep most of the day, and only burned 5 percent over roughly 14 hours of deep sleep with intermittent usage.

Tf101 megatron 1.1.6 guevor 21.11 @ 1.5
[Eee Pad Transformer Android Development] Delacor:
Yeah, no SOD since the last 2 Nights. Now I can be proud of my

TF ;)

Thank you for your hard work!

Which versions work with cm9?
[Eee Pad Transformer Android Development] Thing O Doom:
Good stability on the AOKP one, b38, by far the best video playback so far, amazing.
[Eee Pad Transformer Android Development] redrol:
Holy moly! You were not kidding.. I can play ANY 720P file I own, high profile, whatever. Smooth scrolling.. freaking amazing. This is the best my TF has ever performed. Kudos!:D
[Eee Pad Transformer Android Development] sidneyk:
I've now reinstalled DSP Manager but NOT yet reinstalled the new nvidia codecs and Netflix seems to be just fine. I will now try to reinstall the new nvidia codecs and retest. At this point, version 21.11build 607 seems really stable on Revolver 4.0.3.1 RC3.

Hi, what's the mod used on your picture to show battery level ?

Thk.
[Eee Pad Transformer Android Development] devilpera64:
Ok, for my USB prob was my fault! It was a bad USB pendrive ^_^ it works! is very stable, no problems occurs!
[Eee Pad Transformer Android Development] guevor:
Yesterday I had a marathon workday (12 hours) so when I got home I was very tired and did not have energy to answer questions here.

Now will review the posts by if something was pending.

I carry 90 hours with 21.10 without problems (21.11 is the same with the internal tun), so I'll put on the first page as V22.

EDIT:

Yes, I use a chroot linux without problems.

Do not think I changed anything that could affect the normal operation of wifi, can you check that there is not some other problem (router, etc..)?

Will review the changes between versions to see if I can do something.

Await news about whether the new codecs introduce problems. If so, I could create a new package with the originals, so that each could be installed which will work best.

Good thing, because if had again this problem would have been a nuisance.
[Eee Pad Transformer Android Development] Someone09:
Did a few testruns with some of my vids and so far I can confirm this.

No lag whatsoever.

Need some more testing though.
[Eee Pad Transformer Android Development] devilpera64:
I think that better video is provided also by this last "CPU io_is_busy" feature...i was thought that if my Adreno 200 + Qualcomm scorpio can handle 720p (and is 1Ghz single core!) why our TF101 can't handle 1080p? (into the specs Tegra 2 could be capable to show fullHD)
[Eee Pad Transformer Android Development] akyboy:
Hi

Its one included in megatron,...
[Eee Pad Transformer Android Development] sidneyk:
Now I'm scratching my head again. I've re-flashed the new-nvidia-codecs again and Netflix video is running like a champ for the past 30 minutes or so. Maybe Netflix servers were having problems or, again, maybe it was the wi-fi at work, although I was seeing some of the same problem at home, too. Maybe I had a bad flash of ROM or something before.

The only other changes, settings wise, that I have made recently include turning off the 'Force GPU rendering' option in 'Developer options', as I read somewhere that any properly written app will have this enabled anyway and that enabling it may actually cause problems with some apps. I also enabled 4 stagefright options through the app Blade Buddy, enabling player,meta,scan,and http options.I have also set CPU Master with 1200MHz max. and 216MHz min. CPU frequency settings, using interactive scaling and noop i/o scheduler with 50000 min. sample rate and 99% GoMaxSpeed Load and I'm using the default voltages and have everything set on boot.

At any rate, at first I thought maybe the new-nvidia-codecs were using something more 'linux' and less 'Android' since they were from the linux4tegra project, if I understand correctly, but apparently that thought is misplaced. Thanks for a strong performing and stable kernel.
[Eee Pad Transformer Android Development] guevor:
A new version to be tested on TF101G. Should work on TF101 but the changes are oriented to 3g version.

Please test and report if it work better.

Not sure if AOKP supports 3G, in this case could compile a version too.

EDIT:

By the way, before anyone asks, asus kernel 9.2.1.25 is exactly like the 9.2.1.24
[Eee Pad Transformer Android Development] kukky:
excuse me...what is new nvidia codec in second post? do i have to flash zip using cmw? wich benefits?

Inviato dal mio Transformer TF101 usando Tapatalk
[Eee Pad Transformer Android Development] guevor:
The codecs are the nvidia binary part that encodes/decodes media formats, like h264, mp3 etc..

It affects the video decoding.

They are more modern, and some users have reported the videos run smoother.

The zip is for flashing on recovery, like the kernel.
[Eee Pad Transformer Android Development] devilpera64:
Hey guevor now that you reached stability, what are your improvements plans 4 this fantastic kernel? :-)
[Eee Pad Transformer Android Development] Thing O Doom:
I'll confirm that AOKP supports 3g, since the tf101 model is built from phone based source. It's actually more inconvenient for people without the G since we have to remove the phone.apks xD

[Eee Pad Transformer Android Development] Danzano:
I got told nvidia didnt sign even though samsung did and that most linaro tweaks and improvements would not work. Then again it was just someone speaking not a dev so maybe I mean I would like to see it start to happen where possible even if that were the case.
[Eee Pad Transformer Android Development] GrijzeGeest:
Just installed v22 (and the codecs) on megatron 1.1.6 after cache and dalvik wipe. Boots just fine but when I tried to shut down it froze (circle animation stopped). This happened on 2 tries, anybody else have this also? (Was OK with 17c)
[Eee Pad Transformer Android Development] aerdman:
I have to agree. After reading this, I tried flashing the package over v21.6 (the first version to completely eliminate SoDs with ARHD for me, so far), and I couldn't believe the difference in playback. Using H/W decoding with mx player, I can actually smoothly watch all the 720p mkv videos that I couldn't before. I had started to believe that the

transformer hardware could just not keep up, but I'm glad you finally proved otherwise.

Great work Guevor!

EDIT: You are right: Guevor said that the codecs comes separately.
[Eee Pad Transformer Android Development] sidneyk:
No offense, but I don't see in this thread where Guevor said that. I believe the newer codecs are still a separate flashable package and not included in the kernel package. There is a link on the first page of this thread.
[Eee Pad Transformer Android Development] Kasush:
That is correct. Since the codecs have absolutely nothing to do with the kernel they are a separate package. Guevor found them when he was doing some research and made a flashable package for us. That is the extent of it.

I'v just tested V22.1_fb_608 kernel with ARHD 3.3.1_3G rom on my TF101G, 2 SOD's within a hour.

So I reverted back to the 9.2.2.4 stock kernel which was stable for more than one week.
[Eee Pad Transformer Android Development] j3tt3:

Hi!

I have SOD with all kernel's except 15 :mad:

V21.11 Megatron TF101 B50 Frozen at shutdown
[Eee Pad Transformer Android Development] sidneyk:
No problems

I'm running Guevor's latest, 22.1 build 608 on Revolver 4.0.3.1 with no problems at all. I'm on a TF101 and haven't had any RRs or SODs for several kernel versions now, I believe pre-17c. Videos run great, any games I've tried run great, UI is super smooth and responsive. My tablet is docked most of the time and deep-sleep works well. Keep up the good work Guevor.
[Eee Pad Transformer Android Development] klau7:
Is this kernel for cm9 based roms too or only for stock based roms?
[Eee Pad Transformer Android Development] GrijzeGeest:
The same happens with v22.1 , reboot to recovery with the Megatron menu does work (for v22 and v22.1).
[Eee Pad Transformer Android Development] inigoml:
Hi Guevor.

After problems with v21 series (SOD) I've tested V22. As expected, SOD remains since It's V21.11.

This time I've been testing WITHOUT DOCK and problem remains. Reverting to V20 solve this issue

Of course V22 performance is great, but since my power button is failing SOD implies having to remove part of the case in order to reach power switch.

My base ROM is Revolver 4.0.3 RC3 and my TF is a TF101 B60 series.

I could install a debug kernel in order to get more information.

Thanks in advance.
[Eee Pad Transformer Android Development] ethraza:
I' m getting SODs with 21.10 and 21.11 too on ARHD 3.4.1.

I believe 21.4 was ok, going come back to it.

[Eee Pad Transformer Android Development] farsight73:
I went for a short away trip and wanted no headache with my TF stability. So I flashed stock .24 kernel back. After 3 days it is really stable and everything work too.

If only Guevor can use this stock .24 kernel as base for the overclock and other enhancing system tweaking would be really awesome..!
[Eee Pad Transformer Android Development] gkillerx:
"T

It is partly based on. 24 and its rock stable!

Like i mentioned every page or so. Wipe cache plus dalvik!

Geuvor can't you add this in the main topic?
[Eee Pad Transformer Android Development] guevor:
Yesterday was another crazy day, so I could not come even once to the forum. At least I have a couple of weeks where I'll be pressed for time.

After that, maybe I can make a couple of additional variants of the kernel.

This (which works for me perfect), where I have made ​​profound changes in much of the kernel.

Another based on the latest official version for TF101 and one for the TF101G.

These last two, would not have all changes (obviously, if not end up being the same) and will try to put only some of the changes related to performance.

Now review the thread to see if there any questions to answer.

EDIT:

Since V20 I used linaro compilers, but I think that it's much more important to use it on the system that in kernel.

I never turn off the tablet, so I have not noticed the problem. I will check to see if I can find the cause.

Ok, it is clear that the problem persists with TF101G. The information that worked with v15 (and I understand that in the v16 not) can serve to locate the problem.

Always the best information to locate a problem, if we know which version just appeared.

Have you tried all the intermediate versions?

It can be tiring, but if we can determine which version you showed up the problem, the solution would be much easier.

In your case, with the problem of the button, do not ask that you try it, only if you remember the tests.

For others, if they notice problems, the ideal is to determine from which version actually exists (sometimes we have not encountered the problem in intermediate versions and we think that there not exist, which leads to error)

Using dock? If so, maybe the kernel log could help.

In my case now have 140 hours uptime with the kernel and I have done 3 charges, but the latter I'm still at 100% / 60%. I use both with and without the dock (usually at home with dock and outside almost always without)

I use it a lot, and has been lasting me about 3 days per charge (tablet + dock).

Anyway, I think is a very reasonable time, so if time is short, there must be a specific problem (such as SOD that some people have regularly, while others do not suffer) and not something generic, so need to locate the problem.
[Eee Pad Transformer Android Development] qwertyleiria:
I can test every kernel if you want... Actually going to start today

Note: on v15 the screen came on from time to time (average 10min), but cpu spy shows that is able to enter in deep sleep.

I let you know the test for all kernels on TF101g b90 later

There is no need to try them all, only until you detect the fault.

V22 on a tf101 with ARHD rom, no dock hangs at shutdown. This is the first version in a long time with any problem. Thanks
[Eee Pad Transformer Android Development] DammedKiller:
I am using v22/21.11 in a tf101 with Megatron and without dock. In my tablet, this kernel is the smoothest ever and no sods nor RR. The only problems I had were some battery drain, which were solved with a cache and dalvik wipe.

Good work Guevor!
[Eee Pad Transformer Android Development] nergrum:
Would it be possible to add to the primary post that these kernels do not work with CM9 nightlys?

If i am doing something wrong, and they do in fact work, I apologize. I was not able to get my WiFi to work with any of the variants of the kernel I tried.

I do, however, appreciate the work you have put into these kernels, all the testing and complining. My tablet was extremely responsive, unlike it has ever been, with your kernels. However, the lack of wifi was obviously a deal breaker for me. Thank you anyways. :)
[Eee Pad Transformer Android Development] cecilyen:
I also observed the shutdown hang problem here. My tablet is B90 with ARHD ROM 3.4.1. If my memory is correct, this was also happen in 21.10, but not in 21.4. I even did super-wipe lite after upgrading to 21.10 from 21.4, but not helping.
[Eee Pad Transformer Android Development] thejust:
same here using aokpcb 2.1 , v21.11 "22" , works fine choosing restart but if i choose shutdown it freezes just before turning off.
[Eee Pad Transformer Android Development] marcmarshall:
version

Sorry if I am missing something obvious here. I have been having bad battery drain with sleeping when docked in recent versions. Finally flashed one of them back that seems good but I don't remember which version it is. In settings it reads as 2.6.39.4-g96e8fd1-dirty.

Can anyone tell me which version this is?

Thanks
[Eee Pad Transformer Android Development] GrijzeGeest:
If you look a bit further it should say a number behind the "#" and before "smp". This build number you can use to find the version by looking in the first few posts of this thread.
[Eee Pad Transformer Android Development] marcmarshall:
I had not noticed that when I looked on the first page of the thread. Thanks but I just decided to try Revolver RC3 again and the ROM puts me back to stock. Can't check that unless I decide to reflash from my Nandroid (although that may not restore the kernel). It would be nice if the "about" info just gave a simple version # so you can know what you are running without having to check on the thread.
[Eee Pad Transformer Android Development] sidneyk:
For me, reboot and power off are working fine. Battery longevity seems to better also. Configuration is in my sig.
[Eee Pad Transformer Android Development] qwertyleiria:
Kernel Tests

Test conditions:

TF101g B90 Docked & Undocked (HD Revolution 3.3.1(3g) rom)

Flashed kernel no wipes, reboot.

After reboot opened gmail, browser and CPU Spy.

Let it enter in sleep automatically (1min).

Try to wake it up every 10min

I tested all of the fowling kernels:

test15-OC1700-fb_266 OK (Tested for more than 24h)

test16-OC1700-fb_275 30min -> ok

test16b-OC1700_311-fb 40min -> ok

test17-OC1700-fb_377 10min -> SOD

test17b-OC1700-fb_381 50min -> ok

test17c-OC1700_387 60min -> ok

test18-OC1700-fb_449 30min -> no SOD but no Deep Sleep

test18d-OC1700-fb_459 20min -> no SOD but no Deep Sleep

test18e-OC1700-fb_460 20min -> no SOD but no Deep Sleep

V19.2-OC1700-fb_477 40min -> no SOD but no Deep Sleep

V19.4-OC1700-fb_504 120min -> no SOD but no Deep Sleep

V20-OC1700-fb_505 10min-> SOD

V21-OC1700-fb_527 30min -> no SOD but no Deep Sleep

V21.3-OC1700-fb_559 60min -> no SOD but no Deep Sleep

V21.4-OC1700-fb_564 20min -> no SOD but no Deep Sleep

V22 -> 10min SOD

I know that time was limited, but all the kernels that i tested before, if i didn't get a SOD in the 1st 5 min, i'll never have them after.

Hope its useful...

keep the good work and THANKS.

V22 #605 on Megatron 1.1.6

shutdown using Rebooter and/or Reboot2Recovery seems ok ;)

no freezing

impressively fast
[Eee Pad Transformer Android Development] guevor:
Many thanks for your effort.

Will try to extract some information, but difficult to find the cause because it not seems to be a simple change. There is no version after which the problem always occurs.

On the problem with shutdown, I can't reproduce it on my tablet/rom (shutdown correctly), so if someone can capture the kernel log and system log, maybe give me some information of the problem.

Ideally, capture the log from the pc with adb. Capture the log while perform the shutdown on the tablet.

From PC to see the kernel log while shutdown, type this before:

adb shell cat /proc/kmsg

And to see the logcat:

adb logcat

Thanks

A normal shutdown kernel log looks like this (I just try again and powered off correctly with this messages.)

logcat and kernel log attached. started the logs then hit power button went to power off, clicked ok on the popup. Tablet says turning off, then it hangs. AOKP 38 Kernel v22. of note these are from two different shutdowns but same thing happens every time.
[Eee Pad Transformer Android Development] tsachi:
I had a couple SOD with V22. I didn't have problems with all the 21 tests, but since this happens so rarely it may have been just luck. The only version that had absolutely no SOD for me was 17c. I started with 15 and kipped 20. I am running revolver and have the dock in almost 100% + micro SD always in. The only thing I noticed about last night was that the system stopped reacting around midnight. I have a scheduler that turns airplane mode on at 11:59. Since I am usually up at that time, the combination of scheduler and deep sleep doesn't happen alot.

I'll try to replicate that and see if I can get a log out.

On the power down, I have no problems turning the unit off or restarting it.
[Eee Pad Transformer Android Development] DroidGnome:
Exactly same problem.. I've no clue if the kernel didn't flash, or what is going on.

I TRIED to flash Kernel-ICS-V21.4-OC1700-fb_564.zip

However About Tablet - Kernel reads: 2.6.39.4-g8066a5a-dirty livux@Tragon)))

There is no # sign, nor smp... did something go wrong? I've never had an issue flashing anything before on any device i owned, but I'm not sure what the 'version' is supposed to show, as it appears obvious that it won't reflect the file name itself.

I've wiped dalvik and normal cache before flashing.

Is this the correct version number for 21.4?

UPDATE:

Ok I managed to figure it out. It seems on some ROMs (Using Revolver 4 by Gnufabio, RC 3.1) the Kernel listing in the About Tablet does NOT show the entire version string.

On a hunch I opened up CPU Spy and it shows the ENTIRE Kernel string as:

Linux Version 2.6.39.4-g8066a5a-dirty (livux@Tragon) (gcc version 4.5.4 20111003 (prerelease) (Linaro GCC 4.5-2011.10) #564 SMP PREEMPT Fri Jun 1 13:00:48 CEST 2012​

And according to the page #1, version 21.4 should be build #564 so I believe it worked just fine. It's just a PITA when the version number isn't as easily identifiable as other ROMs I've dealt with.
[Eee Pad Transformer Android Development] DevourDarkness:
