  • Smooth Scrolling Implemented For XWayland

    One of the latest commits to the xorg-server that's seen relatively few commits this development cycle is support for smooth scrolling with XWayland.

  • AMD Forms A Tiger Team For Catalyst Improvements, Including Linux

    I've found out from various people in the know that AMD has assembled a "tiger team" to tackle outstanding Catalyst driver issues. This tiger team isn't Linux specific, but Linux driver issues will be fully evaluated and tackled by this new group of driver specialists.

  • AMD Releases Open-Source VCE 1.0 Support

    Last year AMD open-sourced their VCE video encode engine code for use by their open-source Linux graphics driver stack with the Radeon DRM kernel driver and RadeonSI Gallium3D and worked out a new OpenMAX state tracker. That open-source code drop only worked on the support for "VCE2" hardware found with the AMD GCN hardware and newer (Sea Islands, Kabini, etc). AMD's open-source Linux team has now gained permission for providing open-source VCE 1.0 support to offer video encode to older Radeon graphics processors.

Linux 4.1 Power Consumption Appears To Improve For Intel Users

Filed under
Graphics/Benchmarks
Linux

A Red Hat developer mentioned to us at Phoronix that they're seeing "drastically improved battery life" in some cases with the Linux 4.1 kernel to the extent that it's up to 2~4 hours of extra battery life with the kernel upgrade to Git. I've since started some fresh Linux laptop battery tests.

Arduino IDE now boarding for all

Filed under
Graphics/Benchmarks

The Arduino IDE is heading into a rather neat consolidation of the numerous Arduino inspired boards out there. The introduction of a mechanism, in version 1.6.2, to allow people to plug their boards into the IDE easily is starting to snowball. To understand why this is important, before 1.6.2’s release if you had a custom board and the tools to make it work with the IDE, then to install them involved copying files into directories, editing files and crossing fingers (and being disappointed often). Anyone who used a lot of boards would find themselves with multiple copies of various versions of the IDE just to keep life simple.

Linux

While I've posted some new AMD OpenGL benchmarks on Ubuntu 15.04 since last week's release of the Vivid Vervet, the Radeon R9 290 wasn't tested since at that time this Hawaii graphics card was busy on other Phoronix test systems. However, due to the interest level in seeing some fresh Ubuntu 15.04 numbers for the Radeon R9 290 series, here's some numbers.

  • CUDA enabled programs

    There is a new repository available with CUDA enabled programs in package format. This contains programs that have been linked to CUDA libraries or have CUDA support enabled. At the moment this is available only on Fedora 21, if there is sufficient feedback I will enable it also for other distributions.

  • Making It Easier To Deploy CUDA On Fedora

    While Fedora 21 ships with decent OpenCL support, if you're running the binary NVIDIA graphics driver on Fedora Linux and wishing to use CUDA-accelerated programs, it's a little bit easier today thanks to a new third-party package repository.

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.

    Linux 4.1 will feature an updated Multiple Device (MD) driver to improve the RAID 5/6 potential for those relying upon Linux Software RAID.

  • 6-Disk ZFS On Linux RAID Server Benchmarks

    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.

KDE and Akademy

  • Akademy Day 4
    For most of the year, KDE—one of the largest free and open software communities in the world—works online by email, IRC, forums and mailing lists. Akademy provides all KDE contributors the opportunity to meet in person to foster social bonds, work on concrete technology issues, consider new ideas, and reinforce the innovative, dynamic culture of KDE. Akademy brings together artists, designers, developers, translators, users, writers, sponsors and many other types of KDE contributors to celebrate the achievements of the past year and help determine the direction for the next year. Hands-on sessions offer the opportunity for intense work bringing those plans to reality. The KDE Community welcomes companies building on KDE technology, and those that are looking for opportunities.
  • KDE Reveals Plasma Mobile
    There are a lot of interesting developments occurring in the field of Linux smartphones right now. With so many different options popping up, fragmentation is a risk, as apps built on one platform fail to migrate to another. KDE's new offering may help to make those apps available to a broader audience.
