With 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!
Itus Networks is set to launch a $149 “iGuardian” network security appliance on Kickstarter that runs OpenWRT Linux and the Snort IPS stack on a MIPS64 SoC.
Few vendors have targeted the consumer network security appliance market, and even fewer have done so with pricing under $500. A San Jose, Calif.-based startup called Itus Networks, however, plans to protect your home WiFi router with a $149, open source Linux iGuardian device that offers both a network intrusion prevention system (NIPS) and a network intrusion detection system (NIDS). The device blocks cyber attacks while also filtering out malware “and other undesirable content,” says the company. Like other network security appliances, it sits between your Internet source and your WiFi router, acting as a security firewall.
[Updated 12:00PM] — Marvell has posted detailed datasheets on its previously opaque Armada 370 and XP SoCs, used in Linux-based NAS systems from Buffalo, Netgear, and Synology.
Until now, datasheets and other details about the ARM-based Armada 370 and Armada XP system-on-chips have been available only under NDA to Marvell customers and partners. During the past month, however, the chipmaker released detailed datasheets on the SoCs, with no restriction or registration required. Both functional and hardware spec datasheets were released, each of which is more like a manual than a typical datasheet.
We were tipped to the Marvell Armada 370 and XP datasheet releases by embedded Linux development and training specialist Free Electrons. (The company is well known here for its regular contributions of videos and slide decks from shows like the Embedded Linux Conference, released under a Creative Commons license.)
Denon debuted a line of Sonos-like wireless multi-room HiFi speakers that stream audio from both Internet and local sources, and run on embedded Linux.
Like the similarly Linux-powered devices available from Sonos, Denon’s “Heos” wireless streaming speakers offer multi-room (multi-speaker) synchronized audio, and can deliver multiple audio streams from disparate sources to individual speakers or stereo-configured speaker pairs distributed around the home. Subscription streaming sources initially offered by Denon include Rhapsody, Pandora, Spotify, and TuneIn, with additional services offering DRM-free tracks “coming soon,” says the company.
While the Radeon R9 290 series is now mature in the marketplace, the open-source Linux driver support has lagged. The Hawaii support had been broken for months (no working 3D on the open-source driver, but will work under the Catalyst Linux driver) and the few open-source AMD developers weren't tasked with fixing it over not being sure why it wasn't working and having no immediate business cases for fixing the support. Fortunately, with a bug comment made tonight, it seems things might be in order.
TinyGreenPC launched a Raspberry Pi and Linux based digital signage player that runs on just 7 Watts, and offers optional WiFi and an OPS interface.
The Pi Media Player is one of the most power-efficient signage players on the market, according to TinyGreenPC, a subsidiary of UK-based embedded manufacturer and distributor AndersDX. It helps that the 7 Watt, Raspian Linux-enabled signage player runs on a Raspberry Pi.
Fresh off the release of ACPI 5.1 by the UEFI Forum, Linux developers are updating their support against this latest revision to the Advanced Configuration and Power Interface. In particular, ACPI 5.1 is supposed to help out ARM.
While accessing the ACPI/UEFI specifications still require jumping through some hoops, the ACPI 5.1 update is reported to fix major gaps in supporting ACPI on ARM. Hanjun Guo has already laid out patches for providing Linux ARM64 support compliant with the ACPI 5.1 specification. ACPI 5.1 has "major changes" to the MADT, FADT, GTDT, and _DSD for bettering up this non-x86 platform support.
Beginning in 2011, Red Hat began providing assistance to the fledgling Fedora ARM distribution. I was Red Hat’s project manager for this initiative. Back then it was a humble secondary architecture under the stewardship of Seneca College. Seneca was working on an OS distribution for the Raspberry Pi, a promising educational tool. Red Hat partnered with Seneca, provided resources to advance development and helped build a community, the open source way. Though Linux had been used on ARM for many years, kernel ports tended to exist in different source trees. Likewise, many userspace packages had been written without multi-core, thread-safe ARM code, so there was a lot of work to be done.
