Is Microsoft Blocking Linux Booting on ARM Hardware?

Back in September last year, there was a bit of a to-do about Microsoft's UEFI Secure Boot technology in Windows 8, when a Red Hat engineer posted the following:

As British as Raspberry Pi?

There's been a lot of chatter about Apple possibly switching to ARM chips for its laptops and even its desktops. Whether or not that is true, it's certainly the case that the ARM architecture is a major success, as a glance at the huge list of major manufacturers employing it for their products confirms: as well many Android phones, the Apple iPhone and iPod touch are to be found there.

Why Linux is Alpha and Omega

I'm sure most people remember DEC - Digital Equipment Corporation - that later rebranded itself as the singularly unmemorable “Digital” before being swallowed up by Compaq in 1998, which was itself digested by HP a few years later. But I wonder how many people remember the DEC Alpha chip.

Microsoft's Pyrrhic Victory in the Netbook War

The rise of the netbook has been an extraordinary saga. When the Asus Eee PC was first launched at the end of 2007, it seemed to come from nowhere: there was no real precedent for such a low-cost, small machine, using solid state storage and running GNU/Linux. The brilliance of Asus's move was shown not just by the rapid uptake of this new form-factor, but also the high level of satisfaction – the only element viewed less positively was the small size of keyboard, an inevitable consequence of the design....

ARMing GNU/Linux Netbooks for Success in 2009

One of the surprises of 2008 was the runaway success of the ultaportable/netbook form factor. Now that systems running Windows XP are available people tend to forget that it was the low cost and small footprint of GNU/Linux that made this category possible in the first place. Without free software, the new machines would have been forced to run Windows Vista, making them too slow and too expensive - and hence failures. It was only because Microsoft saw GNU/Linux walking away with this nascent market that it executed a massive U-turn over Windows XP, and allowed it to be installed on these systems.

ARMed and Dangerous - to Microsoft

It's often forgotten that one of the strengths of GNU/Linux is the extraordinary range of platforms it supports. Where the full Windows stack is only available for Intel processors - even Windows CE, a distinct code-base, only supports four platforms - GNU/Linux is available on a dizzying array of other hardware.

Here's an interesting addition to the list:

ARM and Canonical Ltd, the commercial sponsor of Ubuntu, today announced that they will bring the full Ubuntu Desktop operating system to the ARMv7 processor architecture to address demand from device manufacturers. The addition of the new operating system will enable new netbooks and hybrid computers, targeting energy-efficient ARM technology-based SoCs, to deliver a rich, always-connected, mobile computing experience, without compromising battery life.

The combination of a commercially supported, optimized Ubuntu distribution for ARM, together with Canonical’s ability to tailor solutions to specific ARM technology-based devices and OEM requirements, ensures that highly-optimized systems can be rapidly deployed into the fast growing mobile computing market. ARM’s wide partnership with leading semiconductor and device manufacturers strengthens the mobile computing software ecosystem and extends the market reach for Ubuntu-based products.

Since ARM is based on original work by the ancient Acorn Computers (hello, BBC Micro), this represents a nice coming together of two British-based companies, albeit with global reach.

Opening OpenPandora's Box of Openness

After the open source mobile from Android we have the open source game platform from OpenPandora:

* ARM® Cortex™-A8 600Mhz+ CPU running Linux
* 430-MHz TMS320C64x+™ DSP Core
* PowerVR SGX OpenGL 2.0 ES compliant 3D hardware
* 800x480 4.3" 16.7 million colours touchscreen LCD
* Wifi 802.11b/g, Bluetooth & High Speed USB 2.0 Host
* Dual SDHC card slots & SVideo TV output
* Dual Analogue and Digital gaming controls
* 43 button QWERTY and numeric keypad
* Around 10+ Hours battery life

Why Ubuntu on ARM Could be a Rich Seam

You may have heard of the ARM architecture, but you may not know just how widespread it is:

ARM today announced that the total number of processors shipped by its Partners has exceeded ten billion. The company developed its first embeddable RISC core, the ARM6 processor, in 1991, and its semiconductor Partners currently ship almost three billion ARM Powered processors each year.

So news that Ubuntu is being ported to the architecture is pretty cool:

A Nokia-sponsored project is porting Ubuntu Linux to the ARM architecture. The "Handheld Mojo" team has completed ARM builds of Feisty Fawn (dubbed "Frisky Firedrake") and Gutsy Gibbon ("Grumpy Griffin"), with Hardy Heron compilation starting soon.

Whatever the Question, the Answer's GNU/Linux

It's interesting that whenever people try to come up with low-cost machines for developing countries, the answer is GNU/Linux. The OLPC/XO is the best-known example, but here's another one:

Rather than one inexpensive laptop per child, the answer being presented is a somewhat more powerful computer, with zero maintenance or moving parts, which can be shared by a number of children running free and open source software.

Of course, it's pretty obvious why: the cost of software is zero, which means there's no money there wasted on fat cats in Western countries. But there's another interesting angle:

Perhaps the oddest technical feature of the tablet-style PC is the fact that it runs an ARM-based RISC CPU, the Freescale i.mx31. The key reason for choosing this RISC CPU over a conventional x86 Intel or AMD processor was battery life. Morgan explained that this CPU's power envelope of just 3.5 watts made an 8-hour use possible. The other key reason was that this particular chip had strong video and graphics capabilities, which would be needed to show videos and animations in a classroom environment.

The downside is that it does not run the vast amount of x86 software out there.

The operating system is a cut down version of Debian Linux, recompiled for the ARM architecture, complete with most of the office and communications software expected in a GNU/Linux system.

Oh look: there's that wide platform support again: is this turning into one of open source's best-kept secrets? (Via Linux Today).
