Linux graphics tests of Intel's Broadwell hardware are finally here! Going back to November of 2013 is when Intel began putting out open-source Broadwell HD Graphics code. Since the initial Broadwell code drop, I've written dozens of articles to date covering the Linux kernel work, Mesa DRI OpenGL driver progress, Beignet OpenCL compute support, and other key Linux components work on Intel Broadwell support. A few days ago I received the Lenovo ThinkPad X1 Carbon with Core i7 Broadwell CPU to finally see how the Linux support has panned out for this next-generation line-up succeeding Haswell.
Bryce Harrington, the former Canonical employee part of Ubuntu's X/Mir team turned Samsung open-source employee, has issued the first maintenance update for Wayland 1.6.
Wayland 1.6.1 and the reference compositor Weston 1.6.1 were released on Friday night by Harrington. The Wayland 1.6.1 stable update has just over a dozen changes and they're mostly tiny bug-fixes/corrections but there is also improved handling for some error situations between servers and clients. The brief Wayland 1.6.1 release announcement can be read on the Wayland mailing list.
Following yesterday's NVIDIA GeForce GTX 960 launch, here's an 11-way comparison looking at all of NVIDIA's Maxwell GPUs as well as many Kepler and Fermi GeForce graphics cards under Linux. Beyond the raw OpenGL performance, the thermal and power efficiency data is also available for the tested range of GeForce 900/700/600/500/400 series graphics cards.
Alex Deucher has sent in his DRM-Next changes for the open-source Radeon graphics driver updates that will target the Linux 3.20 kernel.
The new AMDGPU kernel driver for supporting the R9 285 / GCN 1.2 GPUs and newer has yet to publicly appear. However, for the Radeon DRM driver there's still an exciting number of improvements for this next kernel version. The Radeon DRM changes for Linux 3.20 include.
This morning NVIDIA is formally announcing the GeForce GTX 960 as the latest Maxwell GPU. The GeForce GTX 960 is a mid-range GPU priced starting out at $200 and comes with a compelling set of features. The past few days I've been testing out the eVGA GeForce GTX 960 2GB graphics card and in this article are some initial performance figures under Linux.
Martin Peres is now one of the newest members of Intel's Open-Source Technology Center, working to improve the open-source Linux graphics support. On Monday there was a trivial Mesa commit but what was interesting is that it marked Martin Peres' new email address as coming from "linux.intel.com." After checking, on the X.Org BoD page it also now lists Martin's affiliate as Intel. I've also confirmed Martin working for Intel through a source at XDC2014 last year in France where he originally heard this information, which was organized by Martin. (To be clear, Martin isn't replacing Keith, the timing is just a coincidence.)
Like the reasoning for the mass OpenCL Linux comparison, the 2D benchmarks were done since having all of these graphics cards out and testing them on the latest proprietary drivers for the Unreal Engine 4 / Metro Redux game comparison. With not having done any big 2D performance comparison in a while, I ran these few extra tests to look at the 2D performance with the NVIDIA 346.22 driver compared to Catalyst 14.12 for the many different graphics cards.
While Wayland by default replacing the X.Org Server as the default display environment has been talked about for a while within the next-generation Fedora world, it looks like Fedora 23 could finally be the time that the switch happens.
Fedora 23 already has ambitious possibilities like only supporting 64-bit software while one of the more likely proposals is enabling Wayland by default. With Fedora 21, Wayland is shipped with Fedora Workstation as a log-in-time switch for GNOME, but the X.Org Server is still depended upon. With Fedora 22, the Wayland experience will be even better and then for Fedora 23 is when there might be the switch.
