Vega 10 Huge Page Support, Lower CS Overhead For AMDGPU In Linux 4.14

With this weekend marking the ending of David Airlie accepting new feature material for DRM-Next to in turn land in the Linux 4.14 cycle in a few weeks, there’s a rush by Direct Rendering Manager driver maintainers to submit the last of their new feature work of changes they want in this next kernel release…

OpenGL vs. Vulkan On The AMD Ryzen 3

We have previously looked at Vulkan vs. OpenGL Linux game CPU core scaling and Linux game scaling across multiple CPUs but at the time did not have a Ryzen 3 system. Now having Ryzen 3 Linux box, here is a look at how the Vulkan versus OpenGL performance compares on the low-end processor. As well, it’s a fresh look at the NVIDIA vs. RadeonSI/RADV performance.

Hands On With The Tyan Thunder GT24EB7106; Building The Kernel In Under 30 Seconds

The Tyan Thunder CX GT24EB7106 paired with Intel’s new Xeon Scalable processors can offer pretty thunderous performance. This server has just arrived at Phoronix for testing and so far is certainly showing off its potential when loading it with dual 20c/40t CPUs (80 threads combined) and 96GB of DDR4-2666 memory…

HAMMER2 File-System Looks Like Its Getting Closer To Being Usable On DragonFlyBSD

Matthew Dillon began developing the HAMMER2 file-system in 2012 and back then he talked about it being until at least 2013 when it would be usable, etc. Five years later, it’s looking like HAMMER2 is closer to being usable on DragonFlyBSD systems…

Athlon II X3 vs. Ryzen 3: How AMD's Performance Has Evolved & Performance-Per-Watt

Noticing I had an AMD Athlon II X3 425 system still racked up and hadn’t been powered on in a long time, I decided to decomission it, but not before running some final benchmarks on that system. Having the recent AMD Ryzen 3 1200 / 1300X CPUs I decided it would make for an interesting comparison how the old Athlon II X3 compares to AMD’s low-end CPU of today, the Ryzen 3 processors based on Zen. Here are those benchmarks that also include performance-per-Watt and overall AC system power consumption numbers.

NVIDIA Working On A New OpenGL Memory Usage Extension

NVIDIA is working on a new OpenGL memory usage reporting extension, NV_query_resource. Before anyone jumps though to bash NVIDIA over coming up with yet-another-memory-reporting extension for OpenGL, this one is aimed at reporting the usage at an object-level rather than just overall amounts…

Radeon X.Org Driver Gets Fixed Up To Always Allow Page-Flipping With TearFree

It’s fairly rare these days seeing improvements to the xf86-video-ati DDX: the driver for those running a pre-AMDGPU (GCN 1.2) graphics card with this driver paired with Radeon DRM and not using the generic xf86-video-modesetting driver instead. But if you are using xf86-video-ati and use the “TearFree” feature to try to avoid screen tearing, a number of patches landed today…

HMM Revised Its 25th Time, Seeking Inclusion In Linux 4.14

Jerome Glisse of Red Hat has published his 25th revision to the Heterogeneous Memory Management (HMM) patch series. HMM is about allowing a process address space to be mirrored and for system memory to be transparently used by any device process…
