[Nvidia Tegra Note 7] Stark0095:
Shaky beg you to re upload the link to download. It's infected, and I desperately need it.
[Nvidia Tegra Note 7] madmatt2024:
The links to KitKat and Lolipop few comments up worked fine for me.
[Nvidia Tegra Note 7] Donz7733:
Can someone post a working link of lollipop kernel?

The main thread link and MediaFire link doesn't work

Thanks

Nvm, medaifire link works on Laptop. Was not able to download from Tab.
[Nvidia Tegra Note 7] razorjaw:
Yes this post above had good working links. thanks. the original post sent me on a goose chase to close popups...
[Nvidia Tegra Note 7] Chinmayezio@gmail.com:
can't find OC kernal link

there is no link to download Tegra Note 7 OC Kernel can any one provide that :)
[Nvidia Tegra Note 7] joseph 007:
The above given links are good bro

Bro scroll up your screen then you will see the of kernel for both KitKat and lollipop there . ( mediafire backup links )
[Nvidia Tegra Note 7] Addhyan:
Link not working. Can u update the link plz
[Nvidia Tegra Note 7] Donz7733:
The above links are working fine. Please try on PC if it doesn't work on Phone.
[Nvidia Tegra Note 7] jautor:
Can you please reupload stock kernel 4.4
[Nvidia Tegra Note 7] Donz7733:
Stock Kernel 4.4 - https://drive.google.com/file/d/0B_N-d9Atcar1bXRiYWhKYVFwRlU/view

Thanks to [MENTION=5839263]arunbiju969[/MENTION] for the reupload
[Nvidia Tegra Note 7] codec7:
thanks for sharing backup links for stock kernels.. had some troubles when I use oc kernel, my tn7 tend to heatup. and easily drains battery. thanks for the dev though.
[Nvidia Tegra Note 7] 3of12:
Any possibility you could contribute this work to the unofficial Cyanogen 12.1 rom? It would be very appreciated
[Nvidia Tegra Note 7] Superikz:
Is there another link?
[Nvidia Tegra Note 7] yamileon:
hey could I get a new link to the KitKat modded and stock kernel

if possible

thanks

edit my bad i assumed the links above were bad
[Nvidia Tegra Note 7] ToJa92:
Subjectively this kernel feels much faster compared to the stock kernel. Great work!

Also, did you tweak the accelerometer somehow? It feels more responsive, but that might just be placebo.
[Nvidia Tegra Note 7] Shaky156:
Thanks, the whole system should be fast. I had it originally set to 2.5Ghz but down clocked it to 2.1Ghz more safe at that speed
[Nvidia Tegra Note 7] neontigers:
Sorry I made a mistake, no need to be like that.

[Nvidia Tegra Note 7] Shaky156:
Either you do not have root access, or the application is incompatible with our Tegra note devices, I recommend set cpu

I am not sure, I do not flash it with CWM. I flash it with this http://xdaforums.com/showthread.php?t=2586432 , its faster, touchscreen works, its not upside down, and it now supports flashing of nvidia otas, enjoy :)
[Nvidia Tegra Note 7] potalifs:
Hi I flash it with twrp but WiFi doesn't work. Any idea?
[Nvidia Tegra Note 7] potalifs:
What app are you using forma set cpu clock, gpu and scheduler?

Inviato dal mio TegraNote-P1640 utilizzando Tapatalk
[Nvidia Tegra Note 7] Shaky156:
Can you please provide a log?

Set CPU to set CPU clock and schedular only, stock ROM power saving mode etc still works. I shall release an update which will make everything easier for users. Very busy so patience is required
[Nvidia Tegra Note 7] potalifs:
Thanks for fastly reply and I reboot the tab and wifi works perfectly.

Amazing! I didn't think my tablet could be this smooth and responsive.
[Nvidia Tegra Note 7] karehaqt:
Tablet runs a lot smoother now, was hoping it might fix the problem I have with music skipping in Poweramp and other players but alas no. Only seems to happen when I turn the screen off, will just keep using my iPod. Overall though a very positive experience.
[Nvidia Tegra Note 7] JohnnyHempseed:
Thank you, thank you, thank you
[Nvidia Tegra Note 7] ZeroWingUK:
Can you elaborate on the HDMI output? Can we now output at true1080p etc and not have the black borders that are present on the stock kernel? I have been waiting for nvidia to fix this via an ota but would be very happy if your kernel has fixed it!
[Nvidia Tegra Note 7] Shaky156:
You can test this on the next update if you dont mind, I shall attempt to fix this issue on next update.

Previously our device hardware was incapable of outputting 4k resolution output, now the device is capable of outputting 4k to external monitor/tv. This is only the kernel side, I havent checked out the ROM side which could be the limiting output resolution.

I am not aware of black borders, if you can send me logs when using the feature I may be able to fix the border issue, that is not a promise though.
[Nvidia Tegra Note 7] ZeroWingUK:
It is most likely the rom, the problem is that it is outputting to external display at 1200x800 not 720p so most tvs will add black borders to the left and right to correct the aspect ratio.

It also leaves the tablet screen on whilst it is connected to the external screen so the battery draw is high.

(All of this is on stock, I have yet to flash your kernel).
[Nvidia Tegra Note 7] Shaky156:
Can you please flash my kernel and test? Provide logs please when you output to external device

Adb shell dmesg

Adb shell logcat

Thanks

Edit: in future I won't be requesting from users.

Users reporting or complaining about issues from stock or this kernel without logs will be ignored, no log = timewasting

A quick question also, is it possible to further enhance the cpu or gpu frequency? When I load setcpu it shows 2.1ghz as the max. Thank you.
[Nvidia Tegra Note 7] Shaky156:
Pushing the GPU clocks any higher is impossible, I have already tested this our devices are incapable of supporting the voltage and freq for higher clocks. Regarding CPU Yes clocks have been pushed higher and can be pushed higher but we have a limitation. There's a reason why the Increase in performance is not linear, this is due to band with limitations, and I have already checked, its impossible to increase RAM speed. This is why I have removed 2.5Ghz clock speed, there is no benefit, just overheats the device more quickly and drains battery due to high voltage requirement.

True performance gains will be noticed on a custom ROM as I will be changing kernel for custom ROM, while benchmarking the CPU hits low power core a lot I have noticed, If using power save mode then 2 CPU Cores are active and the SOC is limited.
[Nvidia Tegra Note 7] ToJa92:
Could you enable /proc/last_kmsg in the next version of the kernel? My Tegra Note has been freezing entirely shortly after unlocking sometimes, and when it happens my computer doesn't recognize the tablet at all, therefore making it impossible to pull the system log. Perhaps they are saved to /proc/last_kmsg however, which would mean I'm able to post that log.
[Nvidia Tegra Note 7] Shaky156:
I haven't disabled last_kmsg, if an error occurs and system boots, make sure you have USB debugging enabled, adb pull /proc/last_kmsg
[Nvidia Tegra Note 7] BENETNATH:
Hi shaky156, i was wondering if you are planning to put your kernel sources on your github ?

I'm currently working on HP slatebook X2 kernel, which is using Tegra 4 too, might be a good help.

Credits would of course be given to you for any commits coming from your sources,

ben
[Nvidia Tegra Note 7] Shaky156:
I'm away for 10 days so shall be back in roughly 8 days, will upload my sources, you can use the source link to download and compile for your device too, it works
[Nvidia Tegra Note 7] BENETNATH:
Thanks
[Nvidia Tegra Note 7] rchrdcrg:
All I can say is FREAKING SWEET! I still hadn't unlocked my bootloader, but now I *finally* have a reason to void my warranty and get my hands dirty with this thing! Thanks so much... my games are all running a good bit smoother than before! Now if only Nvidia would do something about the 1280x800 HDMI output... if the Shield can output a 1080p signal for games, this thing should be able to as well.

One question, is the minimum frequency locked to no less than 1.122 GHz? I can't set it any lower than that, but I don't know if that's a limitation of the kernel or if it's just the CPU app I'm using (No-frills CPU Control).
[Nvidia Tegra Note 7] Shaky156:
Hdmi output supported at hardware level previously was 1080p but with this kernel it now supports 4k resolution output. The ROM side may need development for outputting 4k. I havent tested it.

There is no lock on frequency, my minimum and maximum frequency is set using set cpu app. Other apps i haven't tested and may not be supported
[Nvidia Tegra Note 7] rchrdcrg:
Well, in terms of output resolution, I was mainly referencing how the Shield, with its 1280x800 screen (same as the TN7) can output in Console Mode to a TV in full 1080p for gaming... that's the feature I've been waiting for since last November when this thing came out. I'm sure that would need to be done on the ROM level, maybe with some features ported over from the Shield.

Also, quick bug report, when using your kernel, I was unable to pair my Moga controller to the tablet, not in native Mode A or in generic HID Mode B, so I had to switch back. I also noticed that, even though I got better scores with 3DMark with the kernel, actual game performance seemed to suffer with a lot of stuttering and lagging. Maybe I should've played around with governors or something, but I just decided to stick with the stock kernel for now. I'll definitely keep my eye on this for updates, though... I do love me some custom kernels!
[Nvidia Tegra Note 7] ToJa92:
I managed to get a log (from /proc/last_kmsg) after a crash that forced my Tegra to reboot automatically after about a minute: http://pastebin.com/raw.php?i=fTrxCAvT

It seems this happened after my Tegra had been charging for 10 hours. What I did was simply unlocking it using my passcode.
[Nvidia Tegra Note 7] Shaky156:
OP Updated with my kernel source with cpu oc gpu oc etc.

That sounds like ROM level. You can attempt using nvidia shield files if you want to test 1080p.

Cant diagnose moga controller issue without a log, same goes for game stuttering and lagging.

charging a device for 10 hours? not really a good idea. Also t takes less than 2 hours to charge tegra note 7

Reason for your reboot looks to be touchscreen.

@ developers, Call this kernel a alpha, just to show what our device is capable of and ofcourse more can be achieved. This kernel will no longer be updated, but developers can grab the official source code from OP and compile.
[Nvidia Tegra Note 7] BENETNATH:
thanks for the source upload !

---------- Post added at 09:20 AM ---------- Previous post was at 08:58 AM ----------

shaky156, i presume you've used the "rel-tegranote-r4" branch, am i correct ?

which toolchain are you using ?
[Nvidia Tegra Note 7] xxeldaddyjrxx:
Will this work on the Slate 7 Extreme?

I was wondering if this will work on the S7E because its based on the TN7
[Nvidia Tegra Note 7] rchrdcrg:
Well, since both the custom kernel and the original one are available, you should be able to give it a try without the risk of bricking your device (but don't hold me to that!), but I do know that the HP S7E isn't quite the same as the TN7, so my best guess is that it may cause issues or not work at all... I'm not quite sure what all HP did to the device, but I know that software updates for it come from HP and not from Nvidia, so there's clearly a difference on some level.
[Nvidia Tegra Note 7] you5urf:
confirmed as working on advent variant of tegra note. Used it for a week. Battery life up and snappier. Thanks Shaky
[Nvidia Tegra Note 7] Syol:
Thank you shaky! And a special thanks for the sources, made some tweaks myself ;)
[Nvidia Tegra Note 7] xxeldaddyjrxx:
its working

Confirmed , its working with no issues :D
[Nvidia Tegra Note 7] akii rock:
further release of android

If there will be further release of new android like android L then this kernal will be supporting that rom? Or we hav to flash stock kernal again if we have to update it to new android? I dont knw ! Plz tell
[Nvidia Tegra Note 7] hacktrix2006:
New Android branches normally bring new kernel requirements so their might be a possibility that this kernel will not work with Android L.
[Nvidia Tegra Note 7] perez6991:
Battery Drain

I don't know how all of you have been getting better battery life, my note drains it's battery a few percent in a few minutes. On balanced mode with no overclock apps installed.
[Nvidia Tegra Note 7] x-dira:
...kernel support swap ram !?

Thanks
[Nvidia Tegra Note 7] Shaky156:
Yes it supports swap, you need to setup and enable it yourself
[Nvidia Tegra Note 7] chp2:
Many thanks Shaky156 for your hard work.

I hope I'll be back at home very soon to test your new Kernel.

I'm wondering if it's possible to flash it with CWM (I don't use TWRP yet) and wich tools we need (you recommend) to get the best from all the new features.

Also, wich ROMs are supported (4.2, 4.3, 4.4)?
[Nvidia Tegra Note 7] Shaky156:
It should be possible to flash with the CWM I first released I'm not too sure if itll work on the other CWM but I recommend flashing the TWRP recovery which is fully functional and much more advanced than CWM.

The latest Stock ROM 4.4 is supported
[Nvidia Tegra Note 7] chp2:
Tested and approved...:good:

Very good Kernel. Very good performances. I love it.

Question 1 : Any plans to offer the ability to tweak the voltages? I'm planning to do some UnderVolting because @ 2.1GHz it eat a lot of juice.

Question 2 : I can't change the governors. It always revert to "UserSpace" and I'm intersted to test "Interactive" (I used CPU Adjuster, Trickster MOD & System Tuner Pro).
[Nvidia Tegra Note 7] Andy4Shurr:
I used this kernel for the first time last night and paired it with my moga controller (moga pro). It took about 4 or 5 attempts to initially get it to pair on the initial A mode but once it did I didn't have any further issues, B mode paired instantly after. No dropouts or anything like that.

Tested on Riptide and MC4, both seem fluid and responsive. No stuttering or lag. I have't touched the governors yet, I'll probably get SetCPU over the weekend.

I couldn't get GT Racing 2 to load but I haven't played that in ages so in all likeliness it's probably the game or install. I'll reinstall at some point, test and if it's still crashing on load I'll test with the standard kernel and see if it makes any difference.

Shaky - big thanks for this. Battery does seem to hold charge a bit better and it definitely seems more snappy!
[Nvidia Tegra Note 7] chp2:
Just wanted to do a (more than a month) feedback.

This Kernel is fabulous.

Until now, so far, so good. Everything work as expected. I even forgot I use a modified and overclocked kernel.

I use my tablet every day heavily for my business, for gaming, viewing movies during my journeys and I see no problems at all.

Really a good job was done here. My only regrets are to see there are no more activity in this thread.
[Nvidia Tegra Note 7] rchrdcrg:
I 100% agree, I've enjoyed using it and am also sad to see no updates any more.
[Nvidia Tegra Note 7] Shaky156:
What features did you guys want added to this kernel???
[Nvidia Tegra Note 7] chp2:
Hi Shaky156,

WOW, Nice to see you again in the ring.:highfive:

The first things I see wich make interest, for me, are :

- The ability to change the governors. I tried almost all the kernel tweaking apps and none allow me to change to something else than "User Space".

- Some new type of governors like 'DynInteractive" and I/O schedullers like "RAW" or "BFQ"

- Ability to tweak the voltages by ourself (perhaps my device is able to UV better?)

Also, many kernel related questions :

Does it exist ways to OC the GPU part alone?

Any new kernel tweaks you discovered since the one you was kind enough to share with us?

And finally, perhaps, have you worked on a new custom ROM ?

So many questions we are so pleased to ask to a skilled programer.....;)
[Nvidia Tegra Note 7] hacktrix2006:
Hi all this Kernel is great! as chp2 said would be a nice set of features, also a version that integrates the External to Internal mod would be smashing.

[Nvidia Tegra Note 7] nelsonw:
I agree with this! :)
[Nvidia Tegra Note 7] GlaciaDDF:
If we're going to talk about things that need addressing when it comes to this kernel, although amazing, then we have to talk about the GPU frequency which is too high and causing some graphically intense games to crash for me.

During many benchmark tests too, they will never complete due to the crashing of the gpu.

Another issue I've been having, is occasionally I'll be doing some thing.. And then the app I will be using will crash, much like the gpu and glitch out quite a bit on touch.

Other than those two issues, your kernel is amazing.. And I only wish we had more devs on our device
[Nvidia Tegra Note 7] chp2:
Never had such symptoms. but as I sayd every device has his own life. Perhaps your's is more sensible to heavy OC.

Have you tried to lower the CPU frequency?
[Nvidia Tegra Note 7] nelsonw:
Which app can we use to control kernel?
[Nvidia Tegra Note 7] GlaciaDDF:
It's not the CPU, I've lowered it to that standard clock.

It's the GPU, every time I try to do anything that's heavy on the GPU my device freezes and bugs out.
[Nvidia Tegra Note 7] Shaky156:
I havent touched the controller code area within the kernel if it exists lol so unsure how those issues are happening without a log?

I can attempt something when I have time. All development I am doing has come to a halt, cause i'm just too busy right now. Whenever I do have free time I can

Allow modification of cpu governor

Other Governors will be added and I/O schedulars although FIOPS will still be set automatically as its the best for tablets.

I cannot 100% say that tweaking voltages will be done, but I can only attempt it, if someone can provide a commit for that I will implement it

Right now OC the gpu part alone may be achieved by setting max gpu clock in gpu sysfs, apart from that I havent created a special sysfs for overclocking the gpu

I worked on a custom ROM, but the only issue that was left to fix was Audio which I was close to getting working but did not achieve it so I left it. I may or may not work on fixing audio on custom ROM.

Internal to External mod is provided as a test, and for people that want it on stock kernel, A custom Kernel Internal to External MOD can be made.

Regarding Console mode, can you expand on what you mean??

With my testing I had those issues when the voltage was too high for my soc to handle and causing a kernel panic, crashed the whole system. Our devices cannot handle too high frequency and voltage. I can do one of two things:

1. Reduce frequency and voltage for GPU

2. Provide a SysFS for controlling gpu frequency, so you can select the max frequency that works for you.

I think 2 is the best option here as it crashes on some devices not on all devices.

App recommended is setcpu as it works on this device, but I am unaware of and havent tested other kernel controlling apps that work.
[Nvidia Tegra Note 7] nelsonw:
[MENTION=4802595]Shaky156[/MENTION] thanks for working on this.
[Nvidia Tegra Note 7] chp2:
Nice.

I understand you can be busy so am I. :o

First, thanks on the head up for the sysfs trick. I'll try to locate it and to take a look inside. if you can provide the actual place and the syntax it will help alot.

Concerning the CPU/Voltage settings, I agree with you : the second choice look the best. At least, we are all aware we have to do a backup first. He he ....

For the Custom ROM, you worked on wich version? Cyano, PAC, ...
[Nvidia Tegra Note 7] Somcom3X:
Kind of shocked there was no development going on, so I bought one as my little dev project. Might want to note it is the HP slate 7 extreme, a rebrand with some changes. Tegra devices aren't too gruesome to bring-up by the looks of it.

Just a quick note, how many active members are here?

Edit: reading the the post a few posts above:

Audio eh?
[Nvidia Tegra Note 7] chp2:
Many readers and followers. But...

Since there are so few developpement on our beloved tablet, we are few to post... Bad.

Well, NVidia allready made a great job with a decent and clean ROM, Tomsgt with a complete set of tools and Shaky156 with a great kernel as dev contributors (the rest of thanks goes to Xposed).

My scores are so high, I really don't know if it's even decent to show my PC-Mark score since it's higher than a Tegra Shield tablet (Tegra K1).

Hope something new/big (Lolipop?) will revive this forum.
[Nvidia Tegra Note 7] GodOfPsychos:
first of all, thanks for your awesome kernel [MENTION=4802595]Shaky156[/MENTION]

The following is just my opinion and doesn't mean to criticize your work.

i have to agree with [MENTION=4683845]GlaciaDDF[/MENTION] about the GPU crash problem on intense graphic processes. for an example, when i play 1-3 races in asphalt 8 , it will probably crash the graphic processing. this results in a kind of freeze and then the rendered graphics are glitching a little bit and after that you will get a message that the following app or game crashed.

now about benchmarking apps. it happened to me for the first time in the "3DMARK" app. i was going to run the icestorm extreme benchmark (1080p rendering). And already in the first graphic test, the app crashed in the same way as asphalt 8 did (freeze, glitching, crash message)

EDIT: i found an app to clock the max gpu clockrate down a bit from 708 to 700 mhz (to be specific 696 mhz because the gpu clock can only change in 12mhz steps), and now all the graphic intensive games or benchmark won't crash anymore. so [MENTION=4802595]Shaky156[/MENTION] , could you pls fix this little problem by setting the max gpu clock to 700mhz (specifically 696mhz)
[Nvidia Tegra Note 7] GlaciaDDF:
May I ask what that app was?
[Nvidia Tegra Note 7] GodOfPsychos:
its name is "tegra overclock" (and it is a paid app)

do not download "tegrak overclock" (yes, with the letter "K" in the end) because this is another app from another developer for other devices.
