Linux ARM 64-bit

  • 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.

  • Linux on ARMDebian developers are trying to land upstream support for 64-bit ARM (AArch64) in the Qt tool-kit.

     

  • Linux on ARMLinaro, the open-source development consortium for Linux on ARM architecture, is working on software, tools and drivers that could hasten the release of 64-bit Android. The move is significant because, apart from Apple’s iPhone 5s, no 64-bit smartphones have been announced, a situation that analysts partly attribute to the lack of 64-bit Android for ARM processors, which are the most widely used in handsets and tablets.

  • Linux on ARMCavium talks about and shows their latest enterprise, data center, wired and wireless networking OCTEON and OCTEON Fusion SoCs based on ARMv8 64bit and MIPS, making customized optimized core designs for each in use for cloud servers and base stations among other. CAVIUM claims that their ARMv8 64bit enterprise/server design, due to be released later this year, provides more performance at lower power consumption than Intel´s x86.

  • 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 ARMXen 4.4 is a major release of the open-source virtualization stack commonly used on Linux systems but has increasing support for BSD and other platforms. Xen 4.4 is bringing with it many new features and today 4.4-RC4 was released.

  • Linux on ARMDell offers prototype ARM-based 64-bit server for private testing to 'select customers,' but actual data center use is still a long way off - During the last two years, Dell's been pushing its nose all the more into the low-power 64-bit ARM server tent -- but only by slow inches, much like the rest of the industry.

  • Linux on ARM64-bit ARM based servers should hit the market later this year or earlier in 2015 with SoCs such as Applied Micro X-Gene or AMD Opteron A1100. ARM still has the lead in terms of efficiency with a lower dollar per watt ratio, but Intel is closing in with their new Avoton server-on-chips. However, there’s one aspect where Intel is clearly in the lead: standardization and compatibility.

  • Linux on ARMAround 15 months ago, AMD announced that it would be building 64-bit ARM based SoCs for servers in 2014. Less than a month into 2014, AMD made good on its promise and officially announced the Opteron A1100: a 64-bit ARM Cortex A57 based SoC.

  • 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 ARMShowing off the latest Applied Micro 64bit X-Gene ARM Server Development Board https://myxgene.apm.com/ (which Rob Savoye of Linaro eagerly wants to start playing with), a Dell's 64bit ARM Server solution running Fedora 19 advancing quite a bit with advancing usability, working on a proof of concept for early 2014 for Dell's key cloud server customers before going into mass production (Dell already did some 32bit ARM Server tests in Europe with some customers), some things like Oracle JDK still has to fully come over (needs some tuning) to the platform.

  • Linux on ARMAMD in 2014 will be delivering a 64bit ARM processor for servers. The ARM Architecture and Ecosystem enables servers to achieve greater performance per watt and greater performance per dollar. The code name for the product is Seattle. AMD Seattle is expected to reach mass market cloud servers in the second half of 2014.

  • Linux on ARMUpdated - ARM server chip designer Calxeda has shut down as one of its executives told The Register: "We simply ran out of money."
