XWayland Linux Gaming Performance With GNOME Wayland On Fedora 21

Filed under
Graphics/Benchmarks

Within this article from an updated Fedora 21 stack, I ran some Linux gaming tests under its stock X.Org Server 1.16 environment and then rebooted and logged into the GNOME on Wayland session. From there the Phoronix Test Suite ran and I used the variety of graphics tests at my disposal to push the limits of XWayland.

A Radeon HD 6870 graphics card with the mature R600 Gallium3D driver was used for testing with Linux 3.17-rc6 + Mesa 10.3-rc3. While modern versions of Mesa support OpenGL 3.3 for Radeon Gallium3D, when running the tests under the Wayland session only OpenGL 3.0 was being exposed off the same Mesa build.

Graphics/Benchmarks

A new AMD Catalyst Linux graphics driver has been released today that finally delivers OpenCL 2.0 to Catalyst.

Released today was AMD's OpenCL 2.0 Catalyst driver for both Windows and Linux. The Linux distributions AMD is officially supporting for this driver are Red Hat Enterprise Linux 6.5 and Ubuntu 14.04 LTS, but of course the other usual distributions should work too.

EXT4/Btrfs/XFS/F2FS Benchmarks On Linux 3.17

Filed under
Graphics/Benchmarks

With the Linux 3.17 kernel due out soon, here's our routine file-system benchmarks we do each kernel cycle to see how the popular Linux file-systems have evolved between kernel releases.

Earlier this month I did a 9-way file-system comparison on Linux 3.17 while in this article are the four most common Linux file-systems as we see how the performance evolved compared to Linux 3.16 stable. With Linux 3.17 there were notable changes to XFS and new F2FS features while the Btrfs changes were largely rejected.

Early Adopters Already Hit By Fedora Dropping Old Linux GPU Drivers

Filed under
Graphics/Benchmarks

Long story short, in the case mentioned above, the SiS driver works much better than the generic xf86-video-vesa and xf86-video-fbdev generic drivers and now this user running their aging system on the latest Fedora Linux development code is left without the dedicated DDX. In that case, the user discovered that Mageia's SiS DDX driver that's packaged happens to be ABI compatible with the Fedora X Server (at least temporarily), so he's back to using his preferred driver without burdening the Fedora developers in supporting an out-of-date, open-source GPU driver.

While Linux is commonly referred to as being able to run on almost anything, especially aging PCs, more Linux developers are realizing the burden in trying to maintain support and compatibility for older hardware; in some cases there's just regressions while in other instances the latest code can be completely broken for months until a user notices. What's your views on Linux maintaining support for old hardware? Let us know in the forums.

Graphics/Benchmarks

Several hours ago Valve finally released to the public the Linux port of Counter-Strike: Global Offensive! This has been one of the most sought after titles to come to Steam on Linux by gamers and now it's finally out there. Of course, soon as it was made public, we added support for the game to our benchmarking software. After a very busy night, here's the first widely available benchmarks of Counter-Strike: Global Offensive running natively on Linux. Up for this first round of testing are an assortment of AMD Radeon and NVIDIA GeForce graphics cards with the proprietary graphics drivers.

Mesa Gets Closer To Having OpenGL 4.0 Tessellation Support

Filed under
Graphics/Benchmarks

A significant patch-set was published on Saturday night that implements the driver-independent bits of OpenGL 4's ARB_tessellation_shader extension inside Mesa.

The tessellation support has been one of the big pieces missing from Mesa's OpenGL 4 implementation and fortunately it's getting close to mainline. Chris Forbes of Intel published fifty-six patches this weekend that implement the driver-independent portions of the extension inside Mesa. Of course, the driver portions still need to follow for it to be useful.

AMD's RadeonSI Gallium3D Driver Sees Some Improvements

Filed under
Graphics/Benchmarks

Marek Olšák has published another big set of fixes/improvements to the open-source RadeonSI Gallium3D driver.

On Friday, Marek posted a set of 15 patches against the RadeonSI Gallium3D driver, which for those out of the loop is the driver that handles AMD's Radeon HD 7000 series GPUs and newer. These 15 patches vary in nature but come down to "random improvements" ranging from improvements/clean-ups to DB registers and MSAA, code clean-ups, and OpenGL Geometry Shader fixes.

China starts Windows wipe-out, switches to Linux

China is presently in a situation to completely eradicate Windows from the country. Though this is not immediately possible, the map to wipe-out the Windows operating system from every computer is planned over a period of a few years from now. According to a report on SoftPedia, China has planned to move away from Microsoft Windows completely. Recently, China had announced the ban of Windows 8 in the country accusing Microsoft of spying the China government and businesses via the operating system. China has made it mandatory to all organizations to switch from the Microsoft Windows operating system to a locally developed operating system based on Linux. China believes that by the year 2020, they will successfully eradicate Windows and would have an already switched to a more powerful and secure operating system of their own. Read more

Free-software pioneer says it's all about liberty

When it comes to code that runs a computer or a program, Richard Stallman believes it should be free. Not only at no cost to the user, but unshackled and independent. To Stallman, it is a matter of liberty, not price. “We say free software as in ‘free speech’ not ‘free beer,’” Stallman said. The computer programmer and activist shared his views, which earned him the MacArthur “Genius Grant,” during a presentation at Weber State University on Thursday. Read more

Samsung fires another shot at Microsoft in Android patent battle

This move came as no surprise to lawyers who've been following the case. One intellectual property (IP) attorney whose firm is covering the case closely said that Samsung is simply adding another argument to their contention that their existing Microsoft Android patent deal is invalid on business contract grounds. According to Reuters, Samsung said it agreed to pay Microsoft Android patent license royalties in 2011, but the deal also stated that Samsung would develop Windows phones and share confidential business information with Microsoft. If Samsung were to sell a certain number of Windows phones, then Microsoft would reduce the Android royalty payments. Read more
