Linux on ARM
Summary: A new draft of Microsoft's Windows 8 hardware certification specs confirms what we already knew: the new Secure Boot feature won't lock out Linux on hundreds of millions of new PCs. But Linux backers are demanding the right to hack a new class of devices that doesn't yet exist.
Microsoft is planning to require ARM-based devices carrying the Windows 8 logo use Secure Boot, making it difficult or impossible to install Linux or other operating systems.
With Windows 8 coming out later this year, there has already been controversy about whether computers that ship with Windows 8 will have the ability to run Linux, either as a replacement for Windows or in a dual-boot setup.
Microsoft's Secure Boot feature will be mandatory on ARM-based Windows 8 tablets, according to a discovery in Windows hardware certification documents just found this weekend. While it will be optional on x86, disabling Secure Boot "must not be possible" on ARM. As described, it would prevent any unsigned operating system from running on the resulting hardware, including Linux and variants on it, like Android.
I had previously installed Sourcery G++ ARM Linux toolchain in Ubuntu to build some software running in Debian, but I encountered some issues with some libraries (libavg) that use gethostbyname in static libraries without any easy way to make it dynamic.
We're happy to announce that the new Pogoplug Series 4 plug computer has joined the ranks of our officially supported devices, complete with an updated U-Boot installation and a shiny new kernel that enables those USB 3.0 ports people have been itching to make good use of. The installation is also done in such a way that reverting back to stock functionality is dead simple, should you decide that a full Linux install isn't the right thing for you.
UEFI is a technology that forces a computer to only load a digitally signed operating system. This has some security benefits, as it makes parts of the operating system unbootable if they become infected, since the viruses won’t be digitally signed by a reputable vendor.
Microsoft has been discovered to have changed its requirements for the upcoming ARM version of Windows 8. The change essentially will prohibit ARM devices, including PCs, from running operating systems other than Windows 8 after they ship to customers.
The CompuLab Trim-Slice is quite an interesting dual-core ARM Tegra 2 device. This nettop/desktop-oriented system ships with Ubuntu 11.04 by default, but it is also well supported by Arch Linux. In this article are some tests of the dual-core ARM Cortex-A9 1.0GHz system running under Arch.
Could Microsoft block dual booting of another operating system such as Linux in its ARM version of Windows 8? That's the conclusion from Computerworld.uk.com which discovered a provision in Microsoft's Windows Hardware Certification Requirements, which were first posted in December.
Several security vulnerabilities that were discovered in the Linux kernel for OMAP4 packages by various developers, this time affecting the Ubuntu 11.10 (Oneiric Ocelot) operating system, were announced by Canonical.
A security vulnerability that was discovered in the Linux kernel for OMAP4 packages by Han-Wen Nienhuys, affecting the Ubuntu 11.04 (Natty Narwhal) operating system, was announced by Canonical.
Fears that Microsoft would abuse the UEFI Secure Boot feature for their own ends are coming true. - Advice from Microsoft to makers of ARM hardware says that allowing the disabling of the contentious UEFI Secure Boot feature required for Windows 8 must NOT be possible.
OpenFIMG, the open-source graphics driver project that began as the GLES6410 driver for providing a full open-source 3D stack for some Samsung ARM SoCs, continues to be developed and is moving on with its OpenGL ES accelerated support.
