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;

[Q] install Windows 7 on TF101

Before all the hardcore Android fans start swearing at me for asking this question.... there is a reason for asking it.
As the title explains...... has anyone been able to install Windows 7 on the TF101 (aka Transformer) ?
I've read a couple of articles online that the tablet was suppose to come with Windows 7 on it, which would mean that somewhere, someone at Asus has already done it.
Any of the developers on here know how to install Windows 7 on the TF101 ?
Article links below :

http://topsgadget.info/asus-eee-pad-tf101-comes-to-fcc-tablet-with-windows-7/990

Well, I am a Windows guy and I would love to have it running in the Decepticon but as far as I know there is no Tegra version of Windows 7.
You will have to wait for Windows 8.
It would be cool to have VMWare for Android.

I read here somewhere that there might be a problem with drivers. I would like to see that too!
Sent from my TF101

Yeah its an issue with the CPU type, its the same reason you couldn't virtualize or install windows on Macs before they changed to an x86 architecture. Windows 8 is the first one designed to run both on x86 and ARM processors, its much deeper than drivers though, even the applications will have to behave differently.

check out the links..... someone obviously has a TF101 with windows 7 on it.
Just a matter of finding out how it was done.

Since the TF101 uses a Tegra 2 processor (not an Intel CULV as some early press reports stated), and Windows 7 does not support the Tegra 2 architecture, unfortunately installing Windows 7 on it is not possible.
Windows 8 will have ARM support, so there'll be a chance that works...

forgive me for being dumb...... but check the date release on those articles. They are only 2 weeks old. I dont think it would be humanly possible to swap out the chipset, redesign the boards architecture and have it fully released in stores in just 1 week. These guys must have gotten their info from somewhere.

Its not a matter of switching the chip set and redesigning it. Those articles are just plain wrong and off base. It seems like they were just speculating based on other similar tablets being released at the time. The TF101 has an the Tegra 2 which is clearly a fact. All these articles mention completely different hardware. One of them even mentions a core i5.
It is not possible with the hardware that is in the tablet to run any current version of Windows. I promise there is not a TF101 somewhere running Windows 7, even internally at ASUS.

Someone, somewhere, made a mistake and others ran with the story.

Apparently reading comprehension is low here or many of you didn't actually read the article attached and just assumed by looking at the pictures.
1. Pictures are not of the TF101, look at the placement of the mini HDMI vs the headphone jack. This is obviously a different model
2. CPU is claimed to be an Intel CULV model not a nVidia SOC of any kind.
3. As previously stated there is no current Windows desktop version that will run on any type of ARM device, so the current TF won't/can't run windows.
4. Just because the headline is dated two months ago doesn't mean there is a working version, there seems to be just enough to send to the FCC for certification.
5. Most likely a pre-production tablet used for testing and/or development, so yes they can swap internal parts and test to their hearts content.
Just because we may wish it to be true doesn't make it so.
If you really want an Asus tablet running Windows they already have the ASUS Eee Pad (Eee Slate) EP121-1A011M Intel Core i5.

woops... i meant 2 months. (fingers ran away from me..my bad)
...still, that isn't a lot of time to completely redesign tablet architecture.
But, given the benefit of the doubt....what are the chances of even dual booting the WP7, WM6.5 or even the Windows 8 Beta version on these tablets ?
Heck, they were able to install Windows 98 on the HD2. I hadn't done it personally, but saw a thread on how to make it happen.

Why is this in the Dev thread?

Could 1 of the Developers give an indication whether it would be possible to port another OS to these tablets ?

Unless we get a version of NVFlash that works with the Transformer, zero.
Even with a version of NVFlash that works with the Transformer, the chances are pretty close to zero without access to source.

Why is this thread even here?
Maybe it's cocky of me to even ask, but I find it hard to believe that people in the dev section don't understand that Windows is currently x86 and not ARM. It's been that way forever. You'll never get Windows on an Android tablet until x86 versions of Android become commonplace.
Speculation is that Windows 8 will support ARM but I'm extremely skeptical. It makes no sense. ARM versions of windows wouldn't be able to run x86 executables unless there's some sort of emulation layer, and the performance would be horrible. I wouldn't be surprised if Microsoft shelves that feature before Windows 8 is released.
I'm hopeful we'll see native Ubuntu on ARM, but even then, who cares. I mean, we're expecting all this from a $399 tablet here. We splurged on this expensive toy; if we can spend that on a toy, we can buy a cheap laptop/netbook and throw or OS(es) of choice on it.
</rant>

It's definitely NOT possible as others have already stated in this thread. Windows does not currently run on the ARM CPU architecture at all. People have gotten older versions of windows working, only Windows 3.1 and early afaik but they did so through a DOS emulator that you launch from within Android and the performance is supposed to be ****ty.
When Windows 8 comes out, that is said to have an ARM compatible version that we might be able to install, but that's not going to be for a while.

Someone lock and move this thread to trash...

XOOM 2013 Development [B2G][ChromeOS][Ubuntu|Touch][4.4][Linux]

As its taking our community a lot of time to build 4.4 if it ever becomes possible i thought it would be a good idea to start a thread of ideas and any new information for other developments on the xoom.
The idea of this thread is to look to alternative sources of development for the Xoom!
This is what I have seen so far in terms of Ideas from sources other than Android:
IDEAS:
Chromium OS for Tegra (port using tegra 2 drivers)
Kernel based on tegra 2 Open Source Driver Project
Ubuntu Touch (half working port somewhere)
I have a feeling the open source driver could help with the Kernel for KitKat. ive been doing a lot of reading on kernels so i hope to do lots of experimenting =]
CONTRIBUTE HERE ANY IDEAS OR KNOWLEDGE I WILL ADD IT TO THE POST!

Files found for people to mess around with
FOUND NVIDIA TEGRA 2 AND 3 DRIVERS... i dont know if this is the source havnt had the chance to look but heres a zip (SOURCE: Linux for Tegra r16.3)

cousins
Devices that belong to our Xoom Family
Maybe some of the Xooms cousins which share the Nvidia Tegra 2 Gene can help us out !
(image wont upload so heres a link to Tegra Wiki)
XOOM TEGRA SPECS:
Tegra 250 AP20H (Ventana)... 300Mhz GPU.. the Tegra T20 (Harmony) has 333Mhz and appears to be the only difference... theres also the Tegra 3D Ap25 and T25 which have 1.2Ghz CPU's and 400Mhz GPU's
INCLUDES:
Motorola Atrix 4G
Moto Droid X2 (4.4 dev - i dont think its been successful yet)
Moto Photon (? never heard of this!)
and other brands
WIll be watching the Moto sources carefully then have a look at other manufacturers! (a good 15.. another 25 on the othe version of Tegra 2)

Yeah it would be nice, im looking at chromeOs for arm though if i could get a build working apparently Hexxeh got it ported to the nexus 7 which i believe uses tegra 4?
the main thing im looking at is porting things over from other Nvidia Tegra 2 based projects so anyone with any information on other devices with Tegra 2 give me a shout... any open source work may spark some ideas! =]
