Linux ARM compatibility

  • 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.

  • 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 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 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.

  • 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.

  • Linux on ARMThe Genode OS operating system framework now supports direct memory access via IOMMUs and it also has initial support for ARM Cortex-A15 SoCs. This work can be found in the brand new Genode OS 13.02 release.

  • Linux on ARMhe Linux 3.9 kernel will be another exciting update not only for common x86 users but the ARM hardware support continues to advance too. The 3.9 ARM SoC pull was sent in on Thursday by Arnd Bergmann. Among the noteworthy updates this time around include:

  • Linux on ARMRight before Wine on Android was shown for running Windows applications on Google's Android operating system, the state of Wine for the ARM architecture was talked about. There's a few different Wine ARM scenarios possible, including the ability to run Win32 binaries on a Linux-based ARM system.

  • Linux on ARMFrom the by start of Linaro there has been much confusion about Linaro and distributions. Part of this, I'm sure is because Linaro is different from most open source entities which, by and large, are either industry consortiums or distributions or a mixture of the two.  So what is the relationship between Linaro and ARM Linux based distributions?

  • Linux on ARMGoogle has been working on Native Client for years and it's got years more work if it wants it to become a widely used web technology. One step in that direction is the new support for ARM processors that comes with the new Native Client SDK, version 25, i.e. targeted at Chrome 25, currently in beta.

  • Linux on ARMThe latest bi-weekly release of the Wine software, v1.5.22, has a couple of interesting features. The official change-log for Wine 1.5.22 as released today cites the following highlights:

  • Linux on ARMSince Linus Torvalds raised warnings about the state of the ARM architecture support in the Linux kernel, a huge amount of effort and reorganization has happened in the way Linux supports ARM SoCs. From the addition of the device tree to the pinctrl subsystem, from the new clock framework to the new rules in code organization and design, the changes have been significant over the last one and half year in theARM Linux kernel world.

  • Linux on ARMPiglit is a collection of automated tests for OpenGL implementations that aims at improving the quality of open source OpenGL drivers by providing developers with a simple means to perform regression tests.
