Is The Open-Source NVIDIA Driver Fast Enough For Steam On Linux Gaming?

Filed under
Graphics/Benchmarks
Gaming

While I generally don't recommend Nouveau for Linux gaming systems due to the re-clocking still being a huge work-in-progress to allow the graphics cards to effectively operate at their designated clock frequencies / performance states, I decided to run some fresh tests using the Linux 3.18 kernel and Mesa 10.4-devel to see where things stand today. For the tested Kepler graphics cards that support re-clocking, I tested them at their maximum obtained re-clocked frequencies where the system was stable -- generally still below their rated core/memory frequencies.

Over-Volting Your GPU With The New NVIDIA Linux Driver

Filed under
Graphics/Benchmarks
Linux

Unlike the frequency overclocking done through the NVIDIA Settings GUI, the over-volting can only be done via the command-line interface. It's not clear yet if this is just a temporary limitation if NVIDIA didn't get around to exposing it via the GTK interface or they will keep it CLI-only in trying to discourage novice users from accidentally over-volting their system and causing potential damage, etc.

GeForce GTX 970/980 Linux Benchmarks With NVIDIA 346.16 Driver

Filed under
Graphics/Benchmarks

This week NVIDIA introduced the 346 Linux driver beta with a huge amount of changes and new features -- from GPU over-volting to NVENC and VP8 support. Curiosity got the best of me so I've now ran some GeForce GTX 970 and GTX 980 Linux benchmarks to see if the performance of these new, high-end Maxwell GPUs have changed at all with this latest proprietary driver release.

AMD's "AMDKFD" HSA Driver Is Ready For Pulling In Linux 3.19

Filed under
Graphics/Benchmarks
Linux

Oded Gabbay of AMD sent out the pull request to David Airlie for trying to land the AMDKFD driver in Linux 3.19. The difference between this driver and AMDGPU is that it's already been public for a while where we're still waiting for the AMDGPU graphics driver to be published that's the new DRM driver to be shared with the Catalyst Linux user-space for supporting the AMD Radeon R9 285 and newer GPUs.

While the AMDKFD driver hasn't yet been pulled by Airlie at the time of writing, this driver has already undergone review from upstream developers and in fact revised six times through the public process. Given that the drm-next merge window is still open for a few more days, this driver stands good chances of being merged then as a new Linux 3.19 driver. Friday's sixth version contains just minor changes to the driver compared to last week.

Linux

Intel has sent in another round of graphics driver changes to be queued up in DRM-Next for the Linux 3.19 kernel.

The Intel DRM driver for Linux 3.19 already has initial Intel Skylake graphics support and numerous other changes. Daniel Vetter today sent in yet another drm-next pull request and he says the Intel team will have one more pull request in the coming days once it clears their QA/validation process.

Today's "drm-intel-next-2014-11-07" pull request has Skylake watermark code, reworked audio codec/ELD handling code, Skylake force-wake support, Cherryview support improvements, golden context support for Skylake, and tons of other fixes and improvements.

Find out the full list of these exciting Intel open-source Linux kernel graphics driver improvements via the mailing list pull request. The Linux 3.19 kernel cycle will get underway officially next month once Linux 3.18 has been christened.

Gaming

The latest massive set of Linux test data we have to share with Linux gamers and enthusiasts is a look at Counter-Strike: Global Offensive and Team Fortress 2 when using the very newest open-source Radeon graphics driver code. The very latest open-source Radeon driver code tested with these popular Valve Linux games were the Linux 3.18 Git kernel, Mesa 10.4-devel, LLVM 3.6 SVN, and xf86-video-ati 7.5.99. With this bleeding edge code there were sixteen AMD Radeon graphics cards tested from low to high-end and spanning several generations. Beyond looking at the frame-rate results, there's also power consumption, performance-per-Watt, GPU core temperature, and CPU usage to go along with all of these results.

Intel Xeon E5-1680 v3 & E5-2687W v3 Compared To The Core i7 5960X On Linux

Filed under
Graphics/Benchmarks

While the Intel X99 series motherboards are popular right now with the Intel Core i7 Haswell Extreme Edition CPUs, some of these motherboards are also compatible with the Haswell-based Xeon processors. The MSI X99S SLI PLUS does officially support a number of the Haswell-EP Xeon processors, including the E5-2687W v3 that's a ten core processor plus Hyper Threading. In making for some interesting Linux results, MSI kindly sent over the Xeon E5-1680 v3 and E5-2687W v3 to test them with their X99S SLI PLUS motherboard under a variety of conditions with Linux.

Intel Updates Its Linux Graphics Installer For Ubuntu 14.04 & Fedora 20

Graphics/Benchmarks
Linux

This week Intel updated its Linux Graphics Installer for Fedora 20 and Ubuntu 14.04, but as usual, it's really nothing too special and doesn't earn my high recommendation as there's better ways for users to be running the latest open-source graphics code.

The Intel Linux Graphics Installer 1.0.7 release makes it easy to deploy their "2014Q3 Linux Graphics Stack" on the 32-bit and 64-bit versions of Fedora 20 and Ubuntu 14.04 LTS. The 2014Q3 stack is defined as the Linux 3.16.2 kernel, Mesa 10.3, xf86-video-intel 2.99.911, libdrm 2.4.56, libva 1.4.0, and X.Org Server 1.16.0. These software components have been talked about for a long while already on Phoronix.

Five Great Applications For Systems Admins

Being a systems administrator is a difficult, often thankless job. You’re one of the people responsible for keeping the entire IT infrastructure of your business up and running. What that means is that whenever something doesn’t work the way it should, all eyes immediately turn in your direction. You can hardly be blamed for looking to make your life a bit easier. I’d actually recommend that you do so, truth be told. The less time you spend slogging through all the basics of administration, the more time you can devote to improving your server. To that end, I’ve compiled a list of a few of the best sysadmin apps on the web; tools that any Linux administrator worth their salt should consider using. Read more
