Linus Torvalds announced a few minutes ago, April 27, the immediate availability for download and testing of the first Release Candidate version of the upcoming Linux 4.1 kernel, due for release later this year.
Sasha Levin had the pleasure of announcing the immediate availability for download and upgrade of the Linux kernel 3.18.12, an LTS (Long Term Support) version that is maintained for a few more years.
Going back many months there's been work on adding ACPI support to ARM64/AArch64. That long journey may now be wrapping up with a pending pull request for landing full ACPI support for 64-bit ARM in Linux 4.1.
Linux 3.19 brought improvement to btrfs (raid), the network stack, added ARM Coresight, device tree overlays support, and more. Some key changes made to Linux 4.0 include:
After yesterday's announcement for Linux kernel 4.0, Greg Kroah-Hartman has announced today, April 13, the immediate availability for download of the fourth maintenance release of Linux 3.19 kernel, along with new point releases for the LTS (Long Term Support) Linux kernels 3.14 and 3.10.
Sasha Levin has announced the immediate availability for download and update of the Linux kernel 3.18.11 LTS (Long Term Support), a release that brings a great number of bugfixes, updated drivers, and other important improvements to the most advanced LTS version of the Linux kernel.
Peter Robinson, on behalf of the Fedora Project, has announced today, March 30, that the recently announced Fedora 22 Alpha Linux kernel-based operating system is now available for the AARCH64 and POWER64 (PPC64/PPC64LE) architectures.
Greg Kroah-Hartman has announced today, March 26, the immediate availability for download of the third maintenance releases for Linux 3.19 kernel, along with Linux kernels 3.14.37 LTS and 3.10.37 LTS. Additionally, Linux kernel 3.18.10 LTS was also unveiled a couple days ago.
Greg Kroah-Hartman had the pleasure of announcing earlier today, March 7, the immediate availability for download of the first point release for the Linux 3.19 kernel, which is the current stable branch of the Linux kernel, the core of any GNU/Linux operating system.
Announced last month was the HiKey 8-core 64-bit ARM development board being based upon the HiSilicon Cortex-A53 SoC. This HiKey board came out of 96Boards as the first certified board by the Linaro Community Board Group. I happen to have some early benchmarks of this eight-core AArch64 development board running Linaro/Debian.
Last year, Red Hat decided that the 64-bit ARM architecture was ready for the data center and cloud. This year, Red Hat announced that its Red Hat ARM Partner Early Access Program has expanded to include more than 35 companies. It also expects them to contribute open-source system-specific software and drivers to the upstream Linux ARM community.
With the next kernel -- regardless of whether it be known as Linux 3.20 or Linux 4.0 -- it will contain support for new ARM platforms.
HiSilicon has showcased their latest server SoC and board at Linaro Connect Hong Kong 2015, with up to two processors with 32 Cortex A57 cores @ 2.1GHz, 8 DIMM DDR3 slots (up to 128 GB RAM), 12 SATA ports, 4 PCIe slots, 10GbE / GbE ports.
With the first being the Hislicon Kirin620 Octa Core ARM Cortex-A53 based $129 HiKey development board, http://96Boards.org is a new open hardware specification for ARM 32bit and 64bit development boards, and a Community Program for software delivery to developers, makers and OEMs.
Linaro has just announced the first release of the year with Linux 3.19-rc3 (baseline), Linux 3.10.65 and 3.14.29 (LSK), Android 5.0.2, and Ubuntu Linaro Utopic.
Marcin Juszkiewicz, the ARM developer at Red Hat responsible for a lot of RHEL/Fedora ARM work, has finally managed to get an X11 Server running on real AArch64 hardware.
arm64 is officially a release architecture for Jessie, aka Debian version 8. That's taken a lot of manual porting and development effort over the last couple of years, and it's also taken a lot of CPU time - there are ~21,000 source packages in Debian Jessie!
HTC Nexus 9 is one of the first 64-bit ARM platform with powerful ARMv8 cores (e.g. not Cortex A53) that both commercially available, and relatively affordable at $399 to $599, at least significantly cheaper than the server boards such as Applied Micro X-C1.
I 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.
Linaro 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.
