Linux ARM 64-bit

  • Linux on ARMI like to check the ARM Linux kernel mailing list from time to time, as you may discover a few upcoming ARM processors. This week I found out Exynos 5433 and Exynos 7 are actually two different processors (thanks David!), and that AMD had submitted code for their 64-bit ARM Opteron A1100 SoC for servers.

  • Linux on ARMLinaro 14.11 has been released with Linux kernel 3.18-rc5 (baseline), Linux 3.10.61 & 3.14.25 (LSK, same versions as last month), and Android 4.4.2, 4.4.4, and for the first time Android 5.0 Lollipop.

  • Linux on ARMLinda from HP describes HP's new Moonshot systems, including the new m400 ARM server cartridge, which was demoed at Linaro Connect. HP has launched the TI 32bit and the AppliedMicro X-Gene 64bit ARM Server in HP Moonshot.

  • Linux on ARMClark and Linda of HP give an inside look at HP's Moonshot system configured with their new m400 ARM cartridges. Each cartridge is an individual 64-bit ARM server using AppliedMicro's X-Gene SOC, with 8 cores and 64Gb of RAM with 2 Mellanox 10G NICs. The servers are running OpenStack with a mix of cloud controller services and Nova compute nodes.

  • Linux on ARMA group of researcher at CERN have evaluated Applied Micro X-Gene 1 64-bit ARM XC-1 development board against Intel Xeon E5-2650 and Xeon Phi SE10/7120 systems, and one of them, David Abdurachmanov, presented their findings at ACAT’ 14 conference (Advanced Computing and Analysis Techniques) by listing some of the issues they had to port their software to 64-bit ARM, and performance efficiency of the three systems for data processing of High Energy Physics (HEP) experiments like those at the Large Hadron Collider (LHC), where performance-per-watt is important, as computing systems may scale to several hundred thousands cores.

  • Linux on ARMJon Masters, Chief ARM Architect at Red Hat, talks about Red Hat showing off their ARM Partner Early Access Program (http://connect.redhat.com/early-acces...) running on AMD's ARMv8 64bit Seattle and on the Applied Micro ARMv8 64bit X-Gene Mustang booting both with UEFI and ACPI on a single same Kernel with no changes, common platform.

  • Linux on ARMLinuxCon 2014 - It's practically a given that the ARM processor architecture – so beloved by makers of small devices everywhere – will graduate to servers soon. But before ARM servers can ship in any significant volume, a standardized hardware platform that specifically targets the data center is a must.

  • Linux on ARMWith the Fedora 21 Alpha freeze looming in the rear view mirror, although the object wasn’t as close as it would appear, I thought it was high time that I gave a brief overview of the state of ARM aarch64 in Fedora. Some might assume the silence means not a lot has been happening but this is extremely far from the truth!

  • Linux on ARMThe great thing about Linux is that it runs on nearly everything, and if ARM servers ever take off, they will do so because Linux workloads are ported from X86 and other architectures to run on 64-bit ARM processors. The classic chicken and egg problem is making it difficult for an ARM server ecosystem to develop, and Red Hat is going to help this along with an effort it calls the ARM Partner Early Access Program.

  • Linux on ARMAMD (NYSE: AMD) today announced the immediate availability of the AMD Opteron™ A1100-Series developer kit, which features AMD’s first 64-bit ARM®-based processor, codenamed “Seattle.” AMD is the first company to provide a standard ARM Cortex®-A57- based server platform for software developers and integrators. Software and hardware developers as well as early adopters in large datacenters are eligible and can apply on AMD’s website.

  • Linux on ARMFollowing the recent announcement of the Android™ L Developer Preview, Linaro, the collaborative engineering organization developing open source software for the ARM® architecture, today announced that a port of the Android Open Source Project (AOSP) to the ARMv8-A architecture has been made available as part of the Linaro 14.06 release.

  • Linux on ARMSouthampton, UK, 19th June 2014 - SoftIron® today announced it will showcase its 64-bit ARMv8 based enterprise-grade server motherboard at the 2014 International Supercomputing Conference (ISC), taking place in Leipzig, Germany from June 22-26, 2014.

  • Linux on ARMWhile it will still be a while before consumers are able to see 64-bit ARM hardware on their desk, Mozilla's Firefox web-browser on AArch64 (64-bit ARM) is working.

  • Linux on ARMSummary: Are 64-bit ARM processors ready for the datacenter? Applied Micro and Canonical claim they are with an upcoming demo of the OpenStack cloud using Ubuntu Linux on an X-Gene server.

  • Linux on ARMBack in March Apple open-sourced their ARM 64-bit LLVM back-end (dubbed ARM64) many months after other ARM vendors had already developed a competing 64-bit ARM back-end (dubbed "AArch64" as ARM's official name for architecture).

  • how-toIt is a pity that smartphones and tablets did not come along earlier and did not need 64-bit processing and memory addressing sooner than they did. Had these consumer devices (which are now generally thought of as being indispensable for business as well) required such rich circuitry earlier, then the collective of chip manufacturers who are part of the ARM collective might have put some server-class chips into the field a lot earlier and given datacenters some real alternatives to the X86 architecture by now.

  • Linux on ARMYesterday on Phoronix we covered 12 new feature proposals for Fedora 21 and following that story yesterday were a handful of new feature proposals for this next major Fedora release. On top of the features already approved, the features talked about yesterday and last week's approved features, a few more proposals were sent in yesterday for the approval by the Fedora Engineering and Steering Committee (FESCo) this week. These very latest proposals include:

  • Linux on ARMBack in September of last year after Apple unveiled the iPhone 5S smart-phone with a 64-bit processor, they said they would ultimately open-source their 64-bit ARM compiler back-end... A half-year later, we're finally seeing this code that yields another AArch64 back-end for LLVM.

  • Linux on ARMWhy 64-bit? It seems that is a question with many answers! For some, it will be the need to address more than 2GB or 4GB of memory, for others the need for wider registers and greater accuracy of 64-bit data processing, for still others the attraction of a larger register set. Either way, the 64-bit train is gathering speed and if you don't get on board it may leave you behind!

  • Linux on ARMJon Masters is responsible for leading research and development efforts around the ARM Architecture at Red Hat (in particular, the 64-bit ARM Architecture known as AArch64), instrumental in the creation of the Linaro Enterprise Group, sitting on the LEG Technical Steering Committee, and is elected to represent LEG on the core Linaro Technical Steering Committee.
