Feasibility of desktop on ARM cpu

Filed under
GNU
Linux
OLPC

Thinkpad X60 is old, Core Duo@1.8GHz, 2GB RAM notebook. But it is still pretty usable desktop machine, as long as Gnome2 is used, number of Chromium tabs does not grow "unreasonable", and development is not attempted there. But eats a bit too much power.

OLPC 1.75 is ARM v7@0.8GHz, .5GB RAM. According to my tests, it should be equivalent to Core Solo@0.43GHz. Would that make an usable desktop?

Open-Source Radeon Performance Boosted By Linux 3.16

Filed under
Graphics/Benchmarks
Linux

Besides the Nouveau driver performance being faster thanks to experimental re-clocking when using the Linux 3.16 kernel, there are also performance improvements to note with some generations of AMD graphics processors.

The changes found within Linux 3.16 to benefit the Radeon DRM graphics performance are the GPU VM optimizations and large PTE support. Separate from this performance-related work for this kernel-side open-source AMD update is also HDMI deep color support, HDMI audio clean-ups, and other bug-fixes.

Performance benchmarks: KVM vs. Xen

Filed under
Graphics/Benchmarks
Linux
Server

After having some interesting discussions last week around KVM and Xen performance improvements over the past years, I decided to do a little research on my own. The last complete set of benchmarks I could find were from the Phoronix Haswell tests in 2013. There were some other benchmarks from 2011 but those were hotly debated due to the Xen patches headed into kernel 3.0.

Raspberry Pi DRM+Gallium3D Driver Makes Great Progress In One Week

Filed under
Graphics/Benchmarks
Linux

Last week Eric Anholt left Intel's Linux graphics driver team to go work for Broadcom developing a VC4 DRM/KMS and Gallium3D driver for the GPU that supports the Raspberry Pi.

Eric ended up making more progress in his first week than he anticipated in starting off this new open-source Linux graphics driver project. He ended up getting his work items done that originally he anticipated would take him about one month. The basic "hack driver" is now working to run triangle code running on a kernel with a relocations-based GEM interface. Thursday he already started on the Broadcom VC4 Gallium3D driver, which in turn is based upon the Freedreno driver for Qualcomm's ARM hardware.

Re-Testing NVIDIA's Threaded OpenGL Optimizations For Linux Gaming

Filed under
Graphics/Benchmarks
Linux

Back in 2012 with the NVIDIA 310 Linux driver series a threaded OpenGL optimization was added to the proprietary graphics driver. When this driver premiered we tested NVIDIA's Linux threaded OpenGL optimizations to mixed results. We're back now re-testing the OpenGL threaded optimizations to see if it makes any more of a difference now with modern Linux games and OpenGL workloads while using the latest 337.25 Linux driver.

NVIDIA's OpenGL threaded optimization feature allows offloading the CPU computational workload to a separate processor thread. This feature is designed to benefit CPU-heavy workloads but can potentially worsen the performance depending upon the game/application's particular OpenGL calls. As a result, the threaded optimization feature remains disabled by default while it's been around for two years. For more information on the threaded optimization feature and how to enable it, see the earlier article.

Russia's Baikal processor will be built around an ARM Cortex A57, which ties into Vladimir Putin's goal, established in 2010, to move all government computers over to Linux - another move that's easy to understand given the OS' open-source and modular nature.

Asus C200 Chromebook review: Long battery life, moderate performance

Google

The Asus C200 Chromebook is a 2.5 pound laptop that offers up to 12 hours of battery life and sells for just $249. It’s not the fastest notebook around, doesn’t have the best screen, and some folks might find Google’s Chrome OS operating system limiting. But there’s a lot to like about this little laptop… especially given the low price.

CentOS vs Ubuntu: Which one is better for a server

Finally decided to get a VPS but can’t decide which Linux distro to use? We’ve all been there. The choice may even be overwhelming, even for Linux distros, considering all the different flavors and distros that are out there. Though, the two most widely used and most popular server distros are CentOS and Ubuntu. This is the main dilemma among admins, both beginners and professionals. Having experience with both (and more) distros, we decided to do a comparison of CentOS and Ubuntu when used for a server. Read more

  • FLOSS Weekly 417: OpenHMD
    Fredrik Hultin is the Co-founder of the OpenHMD project (together with Jakob Bornecrantz). OpenHMD aims to provide a Free and Open Source API and drivers for immersive technology, such as head-mounted displays with built-in head tracking. The project's aim is to implement support for as many devices as possible in a portable, cross-platform package.
  • My next EP will be released as a corrupted GPT image
    Endless OS is distributed as a compressed disk image, so you just write it to disk to install it. On first boot, it resizes itself to fill the whole disk. So, to “install” it to a file we decompress the image file, then extend it to the desired length. When booting, in principle we want to loopback-mount the image file and treat that as the root device. But there’s a problem: NTFS-3G, the most mature NTFS implementation for Linux, runs in userspace using FUSE. There are some practical problems arranging for the userspace processes to survive the transition out of the initramfs, but the bigger problem is that accessing a loopback-mounted image on an NTFS partition is slow, presumably because every disk access has an extra round-trip to userspace and back. Is there some way we can avoid this performance penalty?

  • Monday's security updates
  • What does security and USB-C have in common?
    I've decided to create yet another security analogy! You can’t tell, but I’m very excited to do this. One of my long standing complaints about security is there are basically no good analogies that make sense. We always try to talk about auto safety, or food safety, or maybe building security, how about pollution. There’s always some sort of existing real world scenario we try warp and twist in a way so we can tell a security story that makes sense. So far they’ve all failed. The analogy always starts out strong, then something happens that makes everything fall apart. I imagine a big part of this is because security is really new, but it’s also really hard to understand. It’s just not something humans are good at understanding. [...] The TL;DR is essentially the world of USB-C cables is sort of a modern day wild west. There’s no way to really tell which ones are good and which ones are bad, so there are some people who test the cables. It’s nothing official, they’re basically volunteers doing this in their free time. Their feedback is literally the only real way to decide which cables are good and which are bad. That’s sort of crazy if you think about it.
