  • Linux Kernel 3.13.4 Brings ARM64 (AArch64) Improvements

    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.

  • First Public Evidence Of Samsung’s 64-bit SoC Surfaces But It’s Light On Details

    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.

  • New ARM Platforms Supported By Linux 3.14 Kernel

    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:

  • ARM vs. Intel: What It Means for Windows, Chromebook, and Android Software Compatibility

    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.

  • Unregisterised GHC HEAD build for ARM64 (ARMv8/AArch64) platform

    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.

  • LLVM Picks Up Support For ARM's Cortex-A57

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

  • Comparing Linux/Arm JVMs Revisited

    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:

  • Change.org petition, ARM SoC changes for Linux 3.12 invite Torvalds’ fury

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

  • ARM Changes Come About For Linux 3.12 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.

  • Universal ARM/x86 COM standard gets a boost

    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.

  • PyPy 2.1 Ships With Python ARM JIT Support

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

  • Xen 4.3 releases today with ARM server support

    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.

  • Allwinner SoC Still Unlikely For Upstream Linux Kernel

    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.

  • ARM Support Will Change A Lot With Linux 3.10

    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.

  • ARM64 Support Will Improve In Linux 3.10 (AArch64)

    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.

  • New Linux Kernel 3.9 Adds New Features Including KVM on ARM and SSD Caching Support

    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.

  • GDB supports AArch64 Linux

    Linux on ARMThe developers of the GNU Project Debugger (GDB) have released version 7.6 of their tool. Among GDB's new features are native as well as target configurations for ARM's new AArch 64 architecture and the addition numerous new commands and options.

  • Linux 3.10 May Have New Multi-Platform Support

    Linux on ARMThe Linux 3.7 kernel brought ARM multi-platform support and now with the Linux 3.10 kernel it may be extended to support the Samsung Exynos SoC family.
     

  • Linux kernel: Licence problems for old ARM FPU code

    Linux on ARMThe arch/arm/nwfpe/ directory of the ARM code in the Linux kernel includes code which has a licence that contains an indemnity clause. Russell King has pointed out that the Free Software Foundation (FSF) feels that such clauses are not compatible with section 6 of the GPLv2, which is used for the Linux kernel.

  • "Very Disruptive" Change Hurts ARM Linux Support

    Linux on ARMThe Linux kernel is having to remove support for NWFPE and VFP emulation code due to a licensing conflict. Removing NWFPE and VFP from the kernel will effectively render older ARM hardware on Linux useless until a solution is determined.
