Linux ARM compatibility

  • Linux on ARMAs we slowly meander our way towards the pointy end of the Fedora 21 release, with Alpha speeding up in the rear view mirror, the Fedora ARM team are starting to discuss the best way to deal with the blossoming amount of ARMv7 devices that can and do run out of the box on Fedora.

  • Linux on ARMSeveral new ARM devices will be supported by the in-development Linux 3.17 kernel while some less-than-optimally-supported ARM hardware is also getting stripped from the mainline kernel tree. Olof Johansson emailed in the large batch of ARM changes today for the Linux 3.17 merge window. Some highlights for the pull request consisting of around 750 patches include:

  • Linux on ARMAtrust unveiled a “t66″ thin client that runs Linux on a quad-core Freescale i.MX6 SoC, and supports Citrix ICA/HDX, RDP, and VMWare Horizon View protocols.

  • Linux on ARMThe latest Linux kernel's revision number may be 3.14, but don't expect any pi jokes in the release notes. Do, however, look past the matter-of-fact release announcement on the Linux kernel development mailing list for some intriguing improvements in ways that may have implications for cutting-edge processors and for cloud/VM environments.

  • Linux on ARMGreg Kroah-Hartman announced a few minutes ago, February 20, that Linux kernels 3.13.4, 3.12.12, 3.10.31 LTS, and 3.4.81 LTS are now available for download.

  • Linux on ARMAs the majority of our readers should be aware of, Apple’s A7 processor is the first mobile SoC to have adopted the 64-bit architecture. While this doesn’t offer a ton of benefits at this point in time, it’s still quite an achievement, and with the passage of time, you can be certain that more smartphones will feature 64-bit processors under the hood.

  • Linux on ARMThere's support for several new ARM SoC platforms with the upcoming Linux 3.14 kernel. Most of the ARM pull requests for the Linux 3.14 kernel merge window were submitted today. With the ARM SoC platform changes the noteworthy support that's been added includes:

  • Linux on ARMIntel x86 or x64 processors have traditionally been found in laptops and desktops, while ARM processors have been found in lower-power embedded devices, smartphones, and tablets. But you can now buy laptops with ARM chips and smartphones with Intel chips.

  • Linux on ARMI’ve thought I’ll have some ARM/GHC fun again after a while and thought to give a try to ARM64 port. I mean AArch64 mode of ARMv8 platform as the ARM64 of course.

  • Linux on ARMThe LLVM compiler infrastructure has now received support for the Cortex-A57, ARM's highest-end 64-bit AArch64 processor.

  • Linux on ARMIt's been about 18 months since we last compared Linux/Arm JVMs, and with the formal release of the much anticipated Java SE Embedded for Arm hard float binary, it marks a good time to revisit JVM performance. The information and results that follow will highlight the following comparisons:

  • Linux on ARMLinus Torvalds, in response to a petition on to remove RdRand from /dev/random, has lambasted the petitioner by called him ignorant for not understanding the code in Linux Kernel.

  • Linux on ARMAmong the ARM changes for the mainline Linux 3.12 kernel is adding platform support for the Allwinner A20 and A31 SoCs along with continued work on NVIDIA's Tegra 4 support.

  • Linux on ARMElectronics distributor Avnet has added Taiwan-based TechNexion’s computer-on-modules to its board-level embedded products portfolio. The deal raises the profile of TechNexion’s open EDM (Embedded Design Modules) standard that defines three COM sizes usable with both ARM and x86 CPUs, and which incidentally forms the computing core of the open hardware Wandboard SBC.

  • Linux on ARMPyPy, a fast yet compliant implementation of Python, has ARM Just-In-Time compiler support with today's version 2.1 release.

  • Linux on ARMThe Xen Project makes its first release as a Linux Foundation collaborative project today. Xen 4.3 includes a technology preview of support for ARM server hardware, improvements in the open source hypervisor's performance and security and updates to its collection of tools, including another technology preview of integration with the software driven network switching tool Open vSwitch.

  • Linux on ARMWhile Allwinner ARM SoCs are found within massive amounts of the low-cost Android tablets manufactured in China, and there is some open-source Allwinner Linux kernel support, it's still unlikely that the patches will land upstream anytime soon.

  • Linux on ARMIn addition to improved 64-bit ARM support with the Linux 3.10 kernel, ARM architecture support in general will improve a lot with this in-development kernel release.

  • Linux on ARMSupport for the emerging 64-bit ARM Architecture, a.k.a. ARM64 or AArch64, will see better support with the Linux 3.10 kernel.

  • Linux on ARMLinus Torvalds recently released a new version of the Linux kernel -- version 3.9 -- that advances the core of the GNU/Linux operating system with a number of new features. Among other tweaks, the new kernel rolls in new drivers, improves virtualization support, adds new hardware sleep modes, and tweaks file system and storage support.
