Indeed, 021 does NOT boot with latest Bliss, but I have built Temasek v11.4 with KL-021 and no problem after flashing over KLX-021... Maybe a problem because jump to 5.5.1_r2 code... ??
[Shield Tablet Android Development] Pariahnoble:
OK well now I feel like a moron, so there I was, making the move from cwm to twrp (was gonna start working on getting skyrim to run on native Ubuntu mrom.) and twrp BORKED on me. Recovery is dead, gonna have to adb flash, buuuuut, I have to wait to get at a pc. Looking like about a month before I'm up and running on my shield again..... After all my excitement I'm gonna have to sit back and watch for while. I'll be back to crack flashing updates again soon, thanks for the work bito, compared to my phone, you turned my shield into a god lol

EDIT!!!! got it to take a stock ota through factory recovery!!! Just need to to get it rooted again lol. Yayeah!!!! Guess that counts as the fastest month ever !! :D

PS...anyone know how to root with no pc?!?!? O_O

Hello, I flashed kl19 but got into a boot loop. Wiped both caches. Ended up going to superpichu kernel to stabilize. Is kl17 the recommended kernel for stock usage on a stock rom or should I jump to kl21??

Thanks.

Edit: went with kl17 and booted fine. So far so good. Thanks for the development.

[Shield Tablet Android Development] RedFuryJr5:
just curious...

just out of curiosity, is there a kernel you recommend for the temasek build you uploaded? I know that if its not broke, don't fix it but I was just curious if you had a kernel you think we should use. I am currently using KL 019 and not having issues, but I dont know if there is a better one to be using. Thanks in advance!
[Shield Tablet Android Development] BitOBSessiOn:
Last Temasek v11.4 build includes KL-021... That's the kernel I recommend. You can flash KLX-021 over it if you want OC or test ROW IO scheduler.
[Shield Tablet Android Development] BitOBSessiOn:
Mpdecission is a specific hotplug driver for qualcomm cpus. It's not used in nvidia socs. We have a generic cpu hotplug driver managed at kernel level.

An alternative could be using intelliplug, as alternative and (in theory) more efficient cpu hotplug driver.

Anyway, in my experience, sound issues are produced because a bad sound driver implementation by nvidia.

We can treat to use another driver, or get a full (and correct) working version (next OTA 3.0..?).

We have a beast, but bad managed by default nvidia sw.
[Shield Tablet Android Development] feelpt:
Step by step I see you opening this beast's cage. Last temasek with kl21 is close to perfection. Yesterday after 30mins music on YouTube I finally heard the glitch... Besides that the ROM/kernel are running better than ever.
[Shield Tablet Android Development] Mojar7070:
Hello again, kl21 booted fine and running well. My issue for all 3 kernels kl 17,19,21 is that when I plug the tablet into a TV via hdmi the the shield console mode window either freezes when I select an option and would have to restart or when it doesn't freeze the selection does not register onto the TV. Ex: when choosing the console mode, it applies as mirror mode. Or when mirror is chosen right after. The mode selection freezes.

I'm on stock Rom 2.2.1 ota. Currently switching back and forth between kl17,19,21 and superpichu kernel. I wiped cache and dalvik in between each flash. No sound mods, I do have adaway installed and some other rooted apps.

Thanks I advance for the help.

[Shield Tablet Android Development] BitOBSessiOn:
I'm trying a modified version with revised HD audio parameters, how can I reproduce audio glitch/problems...?

I'm thinking about an intermediate kernel version with extra features (extra no official code) but no OC... We can try with Sabermod instead of UBER/Linaro toolchain...

Hi,

I've an EU LTE tablet.

Is the wx_un_do Kernel the right variant for this model?

Thanks.
[Shield Tablet Android Development] BitOBSessiOn:
Yes, for stock. For CM variants you can use wx_na_do.
[Shield Tablet Android Development] Primetime_de:
Just tried KL-020 and KL-021 (wx_un_do). With both Kernels the tablet hangs while booting (Nvidia Logo) sometimes.

After ~30 sec. the device reboots automaticly and the Stock ROM is booting normaly.

Think this happens randomly. Any ideas?

Apart from that the Kernel is great! Outstanding job!
[Shield Tablet Android Development] BitOBSessiOn:
I know this happens sometimes after flashing... (TWRP??) Never after a normal reboot... Can it be your case?
[Shield Tablet Android Development] Primetime_de:
I flashed with fastboot and it happened on the first boot indeed but also afterwards too.

Any logs I can give you? How?
[Shield Tablet Android Development] feelpt:
Someone mentioned that new cm sources handle partitions a little different than before. I had that while trying to flash new kernel in older version of cm. Solved it by wiping internal sdcard and flashing ROM and kernel again
[Shield Tablet Android Development] Primetime_de:
Edit:

Here was rubbish, sorry.

I use Stock, no CM.
[Shield Tablet Android Development] albertorodast2007:
Experiencing it also on stock (flashed from scratch, cero, nada) so it's not about CM partitions. Sometimes it boots sometimes it won't. I'm also experiencing an almost unnoticeable screen flickering. Could both issues be related to voltages? Voltages values are stock in KL and KLX buddy?
[Shield Tablet Android Development] BitOBSessiOn:
Yes, voltages are default in KL, little bit altered in KLX for higher freqs...

Working in a new (more stable?) version...
[Shield Tablet Android Development] xanthrax:
KL on stock ROM, Wi-Fi only version, no problems so far, using multirom, far smoother than stock kernel

Going to KL from KLX, lag is too much
[Shield Tablet Android Development] BitOBSessiOn:
Lags in KL o KLX...? KL is the same thing than KLX minus 300MHz on the top... MHz not needed under my point of view... and not noticeable in normal use... Wipes? Same config...?
[Shield Tablet Android Development] BitOBSessiOn:
I'm testing KSE-023 for stock and KAE-023 for latest CM builds... Available for downloading. Same config, with ROW and some audio and wifi tweaks... KSE is Sabermod TC and KAE is built under Arter TC. No OC.
[Shield Tablet Android Development] jarpo:
Actually i'm experiencing some lags with kl021 too, both stock and cm. But the most annoying thing is the streaming video problem; i have good wi-fi reception but always stucks buffering, youtube, chrome.... doesn't matter which app is. Don't know if it's really related to the kernel, but if some of you are having the same problems, would be nice to know it.

Tomorrow i'll test the new version.
[Shield Tablet Android Development] Pariahnoble:
Testing kae023 on temasek. Installed fine. Booted fine. Hung on first reboot. At the first nvidia logo, before mulitrom comes up. Primary internal. No secondary. That happens from time to time. It's never something I can recreate. Just boot hangs at times...

Also, is there somewhere I can read up on what the toolchains change/improve/optimize over the stock ones?
[Shield Tablet Android Development] BitOBSessiOn:
Not happy with these toolchains. I will revise Sabermod compiling suggestions and latest patches, anyway next version looking for stability. Probably again with Uber tc.

About booting problems, anybody has experienced it with no MultiROM...? Thnx
[Shield Tablet Android Development] xanthrax:
Yes, multirom may cause boot issues but normal on recovery it works fine

Uber toolchain looks pretty stable on many devices

[Shield Tablet Android Development] albertorodast2007:
Oh but OTA 3.0 is so smooth on my shield. Did you fully wiped the tablet after upgrading? Had to do that when updating to 2.2.1
[Shield Tablet Android Development] gqukyo:
I didn't wipe completely. Did a dirty flash and it works fine. Didn't notice any lag.
[Shield Tablet Android Development] Pariahnoble:
I agree, it's way smoother than the last ota, and yeah I fully wipeded. And I dunno what they did with the color management.... But my Gods, the color is so rich and vivid now.

[Shield Tablet Android Development] Sarge29490:

After playing around with ota 3.0 I dont know if much difference could be made with a custom kernel, i mean everything seems perfect... No lags, no wifi issues, no sound glitches, no hdmi or usb otg problems, battery drain during standby is low, viper and xposed are also running fine and no heat ups or stuttering during heavy use. Navigation is pretty smooth too like app switching etc. :)

[Shield Tablet Android Development] BitOBSessiOn:
Hehehe... ;) Kernel is still 3.10.xx linux version so it should work... other history is initrd scripts in 5.1 vs 5.01... In worst case, we can reflash and no problem... or we can try to put Bito-K kernel in a actual stock boot.img (instead generate a new one, because still we haven't OTA 3.0 sources...),, like [MENTION=1416222]Steel01[/MENTION] has done to provide a stock kexec patched MultiROM boot.img working in OTA 3.0.

hola Bito,

imagino la respuesta pero...

sabes si con la nueva version de tu kernel, se solucionan los problemas de "optimizando apps" al inicio, cada vez que reinicio la tablet, tengo mas de 160 aplicaciones que se tienen que "optimizar" y es un coñazo. se que es un problema del sistema de nvidia, pero pense que quiza el kernel tendria algo que ver.

PD: lei lo de añadir hotplugs, si te sirve de ayuda, aunque imagino que ya lo conoceras, en el foro de la nexus 9, hay ya unos cuantos kernels, entre ellos elemental, que te podrian servir de referencia para trabajar sobre tu kernel, ya que estamos hablando del mismo procesador, solo cambia la arquietectura, aunque creo que con tus conocimientos, seguro que puedes aprovechar muchas cosas.

un saludo y gracias!

---------------------------------------------------------------

hello Bito,

I imagine the answer but ...

You know whether the new version of your kernel, the problems of "optimizing apps" at the beginning, every time you restart the tablet, have more than 160 applications have to "optimize" and is a pain are solved. it is a system problem nvidia, but thought maybe the kernel would have something to do.

PS: I read it to add hotplugs, if it's any help, although I imagine you already will know, in the forum of the nexus 9 there are a few kernels, including elementary, you could be a reference to work on your kernel since we are talking about the same processor, just change the arquitecture, but I think with your knowledge, sure you can take advantage of many things.

greetings and thanks!
