One month ago I detailed the construction process of building a new server room in my basement where Linux performance tests are constantly being done and it's up to about 50 systems running down there. While initially there weren't any thermal concerns, now that it's getting warmer here in the midwest of the United States, temperatures are quickly rising... Here's the steps I did to add some power venting to the basement and already it's sharply dropped the temperatures in this server farm.
With Btrfs recently landing RAID 5/6 improvements and other enhancements, I've been working on some fresh Btrfs RAID benchmarks using the Linux 4.0 kernel.
For those curious about the many hardware components powering "the basement server room" with continuous open-source and Linux benchmarking, here's a list of the key components that have made it thus far.
It was just last month that our new, large-scale test farm was completed while already it's being expanded... Another 42U rack is being added to allow for more systems to go through rigorous benchmarking via the Phoronix Test Suite's Phoromatic.
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.
There's yet more to talk about with regard to the Linux 4.1 kernel and some of the latest patches queued up for merging are the numerous ARM improvements.
My favorite computer desk of the past decade, and arguably my favorite ever, is back on sale and costing less than $100. In the past few years I've bought at least eight of them according to my transaction history and I continue to be very pleased by their quality and price.
For those running Linux on Apple MacBook Pro laptops that have both Intel HD Graphics and a discrete NVIDIA GPU, there's new patches underway for proper GPU switching support.
With the recent big update to ZFS On Linux I've begun running some new ZFS Linux file-system tests. Today are just some preliminary numbers from running ZOL 0.6.4 with various RAID levels across six 300GB H106030SDSUN300G 10K RPM SAS drives.
Launched this week on Kickstarters was Endless Computers, a $169 Linux PC for the developing world. Quite quickly the project has already surpassed its $100k USD goal.
Takashi Iwai sent in his sound driver updates for Linux 4.1, which includes major modernization with the standard bus for ALSA in the sequencer core and HD-audio code.
It's going on one month now that our massive new server/benchmarking Linux and open-source benchmarking farm has been operational. So far things are going great and continuing to churn out a lot of performance data for the very latest Git code of the Linux kernel, Mesa, LLVM/Clang, and other projects on a daily basis.
While usually not presenting any major features each release cycle, the libata feature pull request for Linux 4.1 is a bit more interesting this time around.
As part of the work towards allowing easy UEFI/BIOS updates from the Linux desktop in a standardized manner, Richard Hughes has been developing the new fwupd component.
Allwinner has been taking a lot of heat lately for violating open-source licenses with their Linux binary blob components. They then got caught obfuscating their code to try to hide their usage of open-source code, shifted around their licenses, and has continued jerking around the open-source community.
In continuation of this morning's article about Turning A Basement Into A Big Linux Server Room that detailed my month-long process of building out the new Linux automated benchmark server room, here's details on the software deployment side.
When constantly benchmarking dozens of systems daily in a fully-automated manner there's one issue particularly on Ubuntu that's proved over the past few months to be most annoying...
While Allwinner has been caught violating the (L)GPL and resulted in obfuscating their code and playing around with their advertised licenses, now this ARM vendor is taking things a step further.
Libinput 0.13 was released today as one of the final steps before Libinput 1.0.
A new Apple Mac Mini happened to arrive at Phoronix that sports Intel Iris Graphics. It's now time to start benchmarking this Apple system with Intel Core i5 processor and run some comparative tests against Linux.
Allwinner has yet to clarify their license position on their media codec code or fully open up their encode/decode library for that matter when it's fairly clear they're violating the GPL and recently they've been trying to cover it up by obfuscating their binaries.
Allwinner is pushing their way to the top of the list of companies hated by the open-source community...
The ColorHug ALS is an ambient light sensor developed by Richard Hughes to dynamically control the brightness of laptop panels -- for laptops that don't have a built-in light sensor for said purpose.
The HSA Foundation yesterday announced the official v1.0 release of their Heterogeneous System Architecture specification.
Qualcomm announced the DragonBoard 410c yesterday as their first design in compliance with Linaro's 96Boards standard. The DragonBoard 410c will be available to developers this summer and be powered by Qualcomm's 64-bit Snapdragon SoC.
A Phoronix reader pointed out this weekend the Nyuzi Processor, an GPL/LGPL-licensed design that's inspired by Intel's failed Larrabee graphics processor design. The Nyuzi Processor is fully open-source with its Verilog, documentation, tests, compiler/tools, etc.
Qualcomm's Innovation Center continues contributing to the open-source MDP DRM driver that started out as a reverse-engineered display driver for Qualcomm's ARM SoCs via Rob Clark as part of the Freedreno project.
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.
Valve has started showing off the Steam Controller and the many different Steam Machines within the Steam Store.
Here's another update on the construction of the new Linux benchmarking test farm.
