Linux 4.1-rc1

Filed under
Linux

It's been a normal merge window, and I'm releasing according to the
normal schedule. The few days of travel didn't seem to matter, as I
had internet access at all times.

The merge window is pretty normal in terms of what got merged too.
Just eyeballing the size, it looks like this is going to fit right in
- while 4.0 was a bit smaller than usual, 4.1 seems to be smack dab in
the middle of the normal range for the last couple of years. And all
the patch statistics look normal as well: the bulk of the changes are
to drivers (just under 60% of the patch), with arch updates being
about 20% of it all, and the rest is spread all over.

No earth-shattering new features come to mind, even if initial support
for ACPI on arm64 looks funny. Depending on what you care about, your
notion of "big new feature" may differ from mine, of course. There's a
lot of work all over, and some of it might just make a big difference
to your use cases.

So go out and test. Even -rc1, as raw as it may sometimes be, has
tended to be pretty good. It's not that scary. Promise.

Linux-friendly i.MX6 SBC is loaded with I/O, supports PoE

Filed under
Linux

Gateworks’s latest Ventana SBC runs Linux, OpenWRT, and Android on an i.MX6 SoC, and offers A/V, serial, and mini-PCIe I/O, plus wide temperature operation.

The Ventana GW5220 is nearly identical to the Ventana GW5200 SBC announced in 2013, “but only supports PCIe signaling on one mIni-PCIe slot and adds SPI support,” says Gateworks. Like the other Ventana SBCs, including the recent, higher-end Ventana GW5520, the new GW5220 supports -40 to 85°C temperatures, and runs OpenWrt, OpenEmbedded/Yocto, or Android on a Freescale i.MX6 SoC. Like the GW5200, it supports the dual-core i.MX6 Dual version at 800MHz, and measures 100 x 70mm.

Open-source IoT kit runs OpenWRT, mimics Arduino Yun

Filed under
Linux

A “Domino.IO” Kickstarter project offers an Atheros AR9331 module running OpenWRT Linux, plus two tiny baseboards, one of which is Arduino Yun compatible.

To stand out from the growing number of OpenWRT Linux-based computer-on-modules and tiny, com-LIKE single board computers running Qualcomm’s WiFi-ready Atheros AR9331 system-on-chip, startups are now offering entire modular kit families based on an AR9331. Last month, we saw an Onion OmegaKickstarter project, which has since been funded, based on an AR9331 COM with stackable expansion modules. Now a Hong Kong based startup called Domino.IO has gone on Kickstarter to sell its own kit that expands on a Domino Core COM with Domino Pi and Domino Qi expansion boards, as well as smaller I/O modules that enable further customization.

World’s smallest i.MX6 module has onboard WiFi, eMMC

Filed under

Linux

Variscite unveiled a 50 x 20mm “DART-MX6″ module that runs Linux or Android on the Freescale i.MX6, with up to 64GB eMMC flash and -40 to 85°C support.

Variscite’s claim that the 50 x 20mm DART-MX6 is the world’s smallest computer-on-module based on Freescale’s i.MX6 system-on-chip appears to be a valid one. It beats the smallest ones we’ve seen to date: TechNexion’s 40 x 36mm PICO-IMX6, and Solid-Run’s 47 x 30mm microSOM i4. It’s also just a hair larger than Variscite’s own 52 x 17mm DART-4460, which is based on a dual-core TI OMAP4460 SoC, and Gumstix’s slightly larger 58 x 17mm Overo modules, which use TI Sitara AM37xx SoCs.

Btrfs In Linux 4.1 Has Fixes For File-Systems Of 20 Terabytes & Up

Filed under
Linux

It's nearing the end of the Linux 4.1 kernel and Chris Mason has now sent in his pull request of Btrfs file-system updates for this next kernel update.

This pull request is coming in late in part due to him running a longer series of load tests than normal. For this cycle he changed around the free space cache writeout and wanted to ensure the code is properly conditioned. Changing the free space cache writeout should fix stalls on large file-systems. In particular, over at Facebook they were seeing 10+ second stalls during commits on file-systems with around twenty terabytes of space and greater. Should you happen to have a 20TB+ Btrfs file-system, Linux 4.1 will perform better.

GCC 4.9.2 vs. GCC 5 Benchmarks On An Intel Xeon Haswell

For those craving some more GCC 5 compiler benchmark numbers following last week's release of GCC 5.1, here's some new comparison numbers between GCC 4.9.2 stable and the near-final release candidate of GCC 5.1. Pardon for this light article due to still finishing up work on migrating to the new Phoronix web server while separately working to take care of thermal issues coming about in the new Linux benchmarking server room.

First impressions of Ubuntu 15.04

Canonical's Ubuntu operating system is probably the most widely used Linux distribution in the world. Ubuntu is made available in several editions, including desktop builds, server builds and there is a branch of Ubuntu for mobile phones. Ubuntu provides installation images for the x86, ARM and Power PC architectures, allowing the distribution to run on a wide variety of hardware. The most recent release of Ubuntu, version 15.04, includes a fairly short list of changes compared to last year's Ubuntu 14.10, however some of the changes are significant. Some small changes include an upgrade of the kernel to Linux 3.19 and placing application menus inside the application window by default. A potentially larger change is the switch from Canonical's Upstart init software to systemd. Read more
