Tegra kernel 2.6.36 on android 2.3

Just noticed this over on Notion Ink's website...
Android 2.3 comes with Kernel version 2.6.35. The latest which NVidia Tegra works with is 2.6.36! http://android.git.kernel.org/?p=kernel/tegra.git;a=summary

Perhaps some one far smarter than me can make use of this info...

I don't think the stock tegra kernel has all the drivers necessary for the G Tablet. Because I think people have known about that repository, and as far as I know, nobody's built their own kernel that's worked with the G Tablet, but rather have been using kernels pre-built for the G Tablet or the ZPad.
This is why people keep talking about wanting the source from Viewsonic.
But if somebody wants to try doing a kernel build and seeing what does or doesn't work, more power to you!

This is actually only sort of related, but I noticed screenshots a few days ago of what was supposedly 2.3, but the about phone item show a 2.6.29 kernel version like 2.0 & 2.1 use, while 2.2 uses 2.6.32, and I knew that 2.3 was also getting a kernel update..
Oddly enough noone commented on that in the comment section on that site, and I just couldn't be bothered to create an acct to comment...

I've searched nvidia's git repo for our touchscreen drivers and they are not there. Therefore, trying to build from nvidia's git for the gtab won't do us any good until Viewsonic (malata, etc.) posts the kernel source.

this may sound silly. but can we somehow maybe get drivers from the touchscreen for the tegra? instead of looking for drivers from nvidia for the screen can we look for drivers from the screen maker for the tegra?

Dexter (Possible kernel/driver source) A7

Was searching around about our elocity interesting how this offers a built in 3g or bluetooths and sim card option this product seems quite a bit like our elocity same components too.
Dexter and any other developer see what you kind find out about this, looks like different interface could be the break in the kernel we wanted.
pioneercomputers.com.au/products/configure.asp?c1=183&c2=185&id=3203
Drivers and more under support tab
Hope this is what we needed to really get this ball rolling on other O.S.

Anyone feel free to find out what you can about thisw site and the drivers listed and lets work on pulling what we need from it and establishing a center for all the drivers.

Nice findings.. i tried search naz10 and epad n700, aigo N700 etc.. but no luck, but i guess you hit jackpot here
thanks..

ok, the site does not have any files for this tablet..

Dex I know it list everything for every product they have or so it would seem under driver tab. I wonder if we can email thier support and them compile the files or point them out for us.

Anyone have an in at Compal?
It would be awesome to get our hands on the boards they were making before they removed the GSM provisions.
As for that site, it just looks like a reseller to me.

but you understand your PC?
so if you board has a core2duo with 2GB memory, and you add a Geforce, and as modems are rare, you find a nice windows7 compatible modem card + a wifi from broadcom with integrated bluetooth.
Next guy does almost the same but he uses a different wifi and bluetooth card for his pc..
so we got 2 pc's equipped almost the same but with different wifi/bt and of course on chose panasonic touch display , where the other one got LG touchscreen which again uses different drivers.
its all about drivers, not just the chipset

I will continue the search for every driver for this device. If you could list any known manaufacters and the part they made. I will search for every driver I can, and will keep you up to date with my progress. Keep me informed on your break throughs with honeycomb or if there is something you need to find and I will help.

u-boot, drivers and kernel source
Does anyone have the nvidia Tegra 250 devkit? Supposedly they were going to include u-boot support and source. See tegradeveloper.nvidia.com/tegra/forum/uboot-tegra-250
Does the dev kit even have open source for drivers and kernel patches. Is full support for the tegra 250 already at kernel.org or is it missing some key features?
I've held up on ordering the dev kit since my experience with nvidia is that they tend to keep as much information private as possible even with an NDA in place.
I'd gladly help develop a completely open bootloader with u-boot, Linux kernel and distro for this device if hardware specifications are actually available. Google was talking about a possible tegra based device that surely would include open source, but I don't think that project ever made it to market.

you sign a NDA with Nvidia, so no chance of anyone releasing it to community. if they do if will be figured out, and a lawsuit coming their way..
so thats a no go.
Registered developers with Nvidia, know this, so they wouldn't dare risking a lawsuit..

So in their typical control freak fashion they don't want specs or source getting out into the open. Looks like I'll be skipping the A7 until it gets at least a touchscreen update.

not entirely true, its only the parts you asked about..
kernel is GPL and parts of related drivers follows.. but bootloaders are a protected part, and some the vendor specific parts used to manage the chipset together with their nv drivers.. but thats how i read it..
more might be available, but i have not seen all of it.
toshiba + xoom is the only kernels with drivers i seen so far..

cyanogenmod 7 FINAL BUILD gingerbread tegra harmony release

Wrong: CYANOGENMOD 7 RELEASED, HARMONY SUPPORT, DIDN'T NOTICE ANY POSTS REFERING TO IT
Right: CM7 was released, with Harmony support.
Wrong: SHAME THAT NVIDIA ARE NOT SUPPORTING DEVELOPMENT FOR HARMONY CHIP FROM 2.2 ONWARDS IF REPORTS ARE TRUE
Right: It's a shame that nVidia isn't supporting Harmony developers from 2.2 onwards, if reports are true.
Mod Edit: All caps is annoying. Please don't use it. Thanks.

Yes if you actually look at the other CM7 threads you will see that the Vega changes have been added to the official tree now.....
and how can you go and say that we have cm7 (2.3) and then complain about the lack of nvidia support beyond 2.2 in the same post, completely contradicts itself....

but doesnt the tegra 2 already power a bunch of honeycomb tablets already?

there are two types of tegra 2 boards, Harmony which the vega has supported to android 2.2 and Ventana which the xoom has, supported beyond 2.2

Useless posts removed, OP reformatted. All caps is just annoying.
Also, thank you Lennyuk for your expertise. I actually wasn't aware of the two Tegra 2 revisions. What are the differences between Harmony and Ventana?

as far as I know there is not actually a great deal of differences between the two, I think the ventana board has an extra GPU slot, that might be it.

Interesting. I wonder why that would be since these SOCs don't have modular components, with the GPU being directly integrated into the SOC itself... Weird.

UPDATE 12 APRIL 2011:
Sorry folks looks like I caused a bit of confusion. Since this is a developer forum my comments
were targeted at Tegra Honeycomb developers and for this we’d like to focus on Ventana. For shipping or production products, customers should contact the device makers directly for OS support plans. They are responsible for the OS shipping on their device.
In relation to our linux kernel git repository, NVIDIA will continue to provide full open-source support for all of our kernel components and will push more of that upstream over time.

haha to right

UPDATE 13 APRIL 2011
A lot has been read into a very short post about a Tegra development kit. I'd like to clear up a few points.
First, nothing changes in what we’re delivering to the open source community or customers. NVIDIA will continue to post the Tegra kernel to kernel.org and publish our Android code to our public git servers. Additionally, we will continue to make our BSP (codecs, GPU driver etc) available to all our hardware partners. We will continue to do this and nothing about these processes has changed.
For our partners' Android devices, NVIDIA provides support until the hardware partner chooses to no longer support the device. So, for instance, NVIDIA will support the Xoom on all versions of Android Motorola requests until Motorola ceases to support the Xoom. The same goes for ViewSonic with the G-Tablet, Notion Ink with the Adam, Acer with the Iconia, LG with the Optimus 2X and so on.
In relation to my original reply, that was a response to a specific question about a Tegra 250 Development Kit. Given the confusion, we will work with owners of Tegra 250 Development Kits individually to determine their needs. The term "Harmony" is an internal codename for the Tegra 250 Development Kit. It is not a tablet reference design. Each shipping tablet is a custom design with varying hardware components and requires a custom OS image from the OEM who made the tablet.
Finally, while we cannot support or give out third party peripheral drivers or provide the Android 3.0 source before Google does, we do want to explore whether we can assist the open source ROM makers. We will be reaching out to them today.

Can anyone translate this for me? Are we (Advent Vega users) getting the Tegra 2 update? And is this the one for Honeycomb?
From what I can tell, Yes. Or am I reading this wrong?

There is no "Tegra 2" Update
You are getting confused.
Basically when the Tegra2 boards were given to manufacturers they had one of two designs
Harmony which the vega has
or Ventana which newer tablets have
These are not set in stone, they were just designs that then get built to specific needs by each manufacturer.
Nvidia are not releasing their own stock images beyond android 2.2 for Harmony however they have made it very clear that it is down to each manufacturer to do this, Nvidia will support the manufacturers for as long as they want to continue service on each device.
Advent do not yet know if the manufacturer (Shuttle) will give us a HC rom, however at least 2 other clones of the Vega have confirmed it, so it looks promising.

Point of View is supposed to deliver us a fresh HC ROM, I would be really thankful!
All I need is a rom w/o cellphone stuff, just tablet things to work always with optimizations and no slow downs.. That's why I bought a tablet with tegra... but after news like this, customers like me get pretty sad and will regret buying another device from them. Gz;

[webtop] NVIDIA Releases Tegra 12 Alpha 1 Ubuntu-Based Linux

Being released by NVIDIA this afternoon is the Tegra 12 Alpha 1 Linux release. This is a Linux software release intended for developers using NVIDIA's Tegra 2 platform.

O.... so this replaced webtop? (or might/will?)
Edit: We don't have the Tegra 250 chip, I think we have have the Tegra 200 chip... the driver package is for 250.

The changelog says it supports the 200 series.

Nice but this belongs in the General forum.
If you didn't create it, it doesn't belong in development. It's a nice sticky that is on other devices' development forum and i think it applies here as well.

But it looks like the Alpha Release only supports Tegra 250 "Harmony".
Taking directly from the Release Notes,
Code:
Note: This alpha release of Tegra Linux Driver Package (L4T.ER1 ) is a
release for Tegra 250 “Harmony” only. The information in these release
notes is preliminary

According to pdadb.net Atrix has Tegra 2 250 chip, also wikipedia says it has Tegra 250 AP20H (H stands for Harmony?)

That is correct. There is no Tegra 200.
The Tegra 250 AP20H is the chip used in phones, Tegra 250 T20 is used in tablets. As far as I can tell, the biggest difference between the two SoCs is that the Geforce ULP GPU is clocked higher on the tablets (333mhz vs 300).

So this could be huge for WebTop?

Possibly... but to be honest, I'm not willing to give up Flash to go up to 11.04, let alone things like the Android-In-Window functionality. Updated versions of those are a lot harder to get. It might be able to get an updated Flash if we could find a Linux-based device out there that we could hack, but the others...? Good luck.
I'll be trying an upgrade to Ubuntu 10.04 at some later point in time, but I can't make any promises that it will succeed.

NVIDIA might provide one to some of its OEM/ODM customers, but I don't think they publicly distribute Flash for public consumption. I expect it'll be the same in this case - if we could somehow get our hands on a leak of Flash for Ubuntu 10.10 or 11.04, we might be able to get something working, but otherwise, we're pretty much out of luck.

Depending on what kind of performance gains there are, this could be awesome. Although you wouldn't directly replace it, you'd be better off making a custom "distro" for the atrix using bits and pieces from webtop and combining them with the nvidia build.
Does anyone know exactly how the webtop environment boots? Important thing being the kernel. If it runs similar to a chroot you'd need a custom kernel as well.

Look up tegra on wikipedia we have 200 it says.

There's no such thing as a Tegra 200 chip! Whenever it is referred to that way it is the because it's part of the 200 SERIES. Each being near identical with different clock speeds and possible some specific optimisations for the 3D models.
The Atrix has a Tegra 250 AP20H.

An opensource Mali-400 driver is being developed

A reverse engineered, open-source, Mali-400 driver.
Pretty cool, but don't expect to see it running on the Note soon.
It would be nice to see more opensource drivers!
Imagine if a new Android build's source comes out and a developer already has access to drivers for i.e the camera.
I don't understand why ARM or any other company doesn't make their drivers opensource in the first place.
Popular hardware will get reverse engineered opensource drivers eventually.
Nvidia's optimus for example. It just takes a lot of time.
But a driver is software and software has to be closed source for some reason
Here's a link for some more information if you're interested.

So the waiting begins. Bump this thread next year when they're done

I think its just one of those bloody minded ideas in business. "We don't do it that way because thats not the way we do things." Kind of circular logic stupidity.
If you are selling a product then surely its in your interest for your product to be more useful and become more popular!
Imagine buying a sports car which required you to use a driver with it as you were never allowed to know how to drive it yourself ;-)
