Full ARM support is coming to Ubuntu Linux in April '09 ... http://www.ubuntu.com/news/arm-linux
The press releases says it will support ARMv7 architecture, but I understand that the Qualcomm MSM7201A processor in our Raph's is a ARMv6 ... http://pdadb.net/index.php?m=cpu&id=a7201a
Do those who know more about this level of technical stuff than me (which is very minimal at the processor architecture level) know that although the Ubuntu Linux will support ARMv7, could it be used/support ARMv6 too? And thus it's likely we'll be able to run Ubuntu Linux on our Raph's?
ne updates on this ??

I have seen several QEMU setups, specifically on the Nexus One, Evo 3D, Xperia Neo, and other devices, all running various versions of Windows XP, 98, or 95. I'm looking at the source now. Is there any reason someone hasn't tried to run the Windows CE (PocketPC or WinMo) kernel within QEMU or can it only emulate x86 operating systems?

So according to these articles, ARM emulation is possible.

QEMU booted into the ARM port of Fedora 8
QEMU emulates the ARMv5TEJ instruction set and all the derivative processors families like ARM7, ARM9E, ARM10E and XScale. It emulates full systems like Integrator/CP board, Versatile baseboard, RealView Emulation baseboard, XScale-based PDAs, Palm Tungsten|E PDA, Nokia N800 and Nokia N810 internet tablets etc. QEMU also powers the Android emulator which is part of the Android SDK (most current Android implementations are ARM based). Under development is iEmu, emulator of Apple's iPhone. Starting from version 2.0.0 of their BADA SDK, Samsung has also chosen QEMU to help development on emulated 'Wave' devices.

I've had limited success booting a custom x86 Windows CE 4.0 NK image with the newer WinCE QEMU port for the HD2 but I wouldn't call it usable. CE booted and I could see the mouse cursor but the desktop never appeared. There are real CE drivers for most of QEMU's hardware on x86, so it might just take a bit of fiddling if the ARM qemu builds aren't just broken.
Bochs was able to boot the image fine but it was pretty slow and only worked in the 320x200 VESA mode. One of the newer mobile Bochs builds for Android worked a little better and displays in a higher resolution but it's still slow and lacks networking. I haven't had as much success with QEMU. It seems like there are major differences between the generic c/c++ CPU core for all architectures and the x86 one and I"m pretty sure QEMU runs some x86 code natively even in user mode. It's either that or the mobile versions are quick hacks with some dirty workarounds that break the more obscure OSes. The difference in compatibility between different processor architectures in the same build is evidence enough of that. Though, I haven't tried them in an ARM debian build yet.
And as cross platform as it is, QEMU seems highly optimized for x86 these days. So many OSes that have problems on ARM qemu work just fine on a desktop. It seems to me like QEMU-x86 wasn't ever really extensively tested on ARM and the other less used archs. There is also a newer QEMU port based on 1.x in the Android Market called Limbo which I have yet to try but the current versions use VNC so video output is pretty slow.
If you want to give it a go, the following Windows CE based PDA platforms had x86 images available: Handheld PC 2000, Pocket PC 2002, Smartphone 2002, Pocket PC 2003/SE, Smartphone 2003/SE and of course the generic builds from 2.0-7.0. Most of these will boot on a sufficiently compatible PC with the right nudging and it should be possible to cook custom ROMs with appropriate HDD drivers if you prefer Windows Mobile and know how to modify WM2003 ROMs.
You might want to keep an eye on QEMU-KVM for ARM Linux too. If it ever works well enough on android, that may be able to virtualize an ARM CE image at near native speeds. QEMU does emulate a few CE compatible dev boards but I'm not sure if anyone ever successfully booted CE on them as they're mainly for testing Linux and don't emulate everything.
Edit: Here's a few YouTube videos I found demonstrating an early build of KVM-QEMU booting Android and Ubuntu on a Cortex A15 running Ubuntu:

Color me impressed! If CE can be ported to one of the boards QEMU emulates, (almost) native CE on countless Android devices seems very possible. Porting it on an emulator/VM is likely easier than running it on the metal.
Also, here's a thread about the Raspberry Pi's debian and QEMU. Based on the comments, they seem to have the same odd issues the WinCE and Android ports have.

Does anyone know of any virtualization/emulation software that can run on ARM processors?
I haven't seen anything other than that WINE is being developed such that soon ARM and X86 will have interchangeble compatibility (windows ARM on x86 linux and windows x86 on linux ARM)
I'm getting one of those ARM Chromebooks and it would be cool to be able to keep ChromeOS intact by installing something through the terminal in dev mode and using something like php virtualbox to open the gui through the browser
I'm not too opposed to just putting Ubuntu on it but would like to be able to try out like the ARM version of backtrack
windows support would be assume but unexpected
QEMU?
QEMU supposedly has intermittent support for running on an ARM host, and supports both system (full OS) and user (individual application) level emulation of x86 target. However, they say on their site that ARM host support is only of secondary importance (wiki.qemu.org/Features) and so it may not work too well.
Could be worth a try anyway!
We are look for making tablets for students. I have compared both ARM and Intel based tablet. Also most opt for ARM based. I have specific question in mind.
If we write an apps (or software in case if we use Linux based OS) , will it differ from Intel and ARM processors ? Is it necessary to write processor specific softwares ?
P.S: I guess, this question falls in general category.
I've got a tablet with a dual core Atom Z2560 x86 CPU and 1GB RAM on Android 4.3. After seeing that the CPU officially supports VT-x it came to mind that this kind of hardware can be enough to fully virtualize at least Windows XP or Ubuntu, and even do it pretty smoothly, since I've done it on slower PCs. But I quickly found out that there is no software for doing this. Neither Vmware or Virtualbox seem to have released hosts for Android, and the only software I found that could be sufficient is QEMU, which appears to be designed to translate x86 commands to ARM, and therefore is insanely slow. I'm not even sure if it will work on x86.
Is there any software that can do what I'm asking for ? Or any software in development for this at all ?
As far as I know, there's no such software at this time.
Basically, on the Mate site there is now a Mate download for the GPD Pocket, which does look like a cracking good machine.
Basically, has anybody had the gumption to try this on their Gemini? I have only one Gemini and don't have the skill or the courage to do this myself. If, and it is if, Mate worked on the Gemini, that would be excellent. I know people have Debian working, which is the fork for Ubuntu, which is the fork for....... which is why I'm thinking / hoping it may work.
Thoughts from anyone?
P.
GPD Pocket runs on an Intel x86 processor (like most computers and laptops), which means that it can basically run anything available. Gemini runs on ARM, which is basically the processor that powers mobile phones and some tablets. ARM is a completely different architecture and is not compatible with x86 software. Most of the desktop operating systems (like Windows, mac OS, Ubuntu, etc) focus their development on the x86 platform, since the vast majority of desktops use this architecture of processors. Because Linux is a free and open source OS, it is possible to get the kernel source code and (with a few modifications) compile it to a different architecture. That's what was done for the Gemini (and all other ARM devices that can run Linux), they got the Debian source code and compiled it for the ARM cpu. Some specific hardware settings and drivers were added for the Gemini PDA to make our custom Gemian, a Debian for the Gemini. Ubuntu is based on Debian, and not the other way around. So, to have Ubuntu Mate running on the Gemini requires one step further, to get Ubuntu source code and Gemian customization and drivers, mix it all together to make some "Ubuntian" of some sort... Honestly, I see no advantage in running Ubuntu, since Debian is the root of it. I don't know of a thing you can do on Ubuntu that you can't on Debian. But still, if you really want to have Ubuntu Mate running on your Gemini, on the Android side you can install Linux Deploy. This app only works on rooted Android, but it is totally worth it if you want to run Linux on your device. It allows you to install several distributions of Linux on top of Android, including Ubuntu Mate.
