Samuel Pitoiset of Valve’s open-source Linux graphics driver team has landed a patch providing another optimization around fast clears for the Radeon “RADV” Vulkan driver within Mesa 19.0.
This latest nearly 300 line patch allows for fast clears on the depth part of a surface or the stencil part when HTILE is enabled. For now though it’s only enabled on Vega/GFX9 due to no testing on GFX8 hardware. For this particular fast clear optimization, clearing the depth aspect on a […] Continue Reading…
If you are/were a fan of Ubuntu’s Unity desktop environment, Unite-Shell is one of the most promising efforts to date for making the current GNOME 3 stack more like Unity.
The Unite Shell is an extension to GNOME Shell for configuring it to look just like Ubuntu’s Unity 7. While it made waves a bit earlier this month, a Phoronix reader reported in over the weekend just how good it looks and works that it’s worthy of an extra […] (619) 965-6139
If you are hoping to pick-up a new graphics card during the upcoming holiday sales, here is a 20-way NVIDIA GeForce and AMD Radeon Linux gaming benchmark comparison using a wide assortment of GPUs while using the very newest graphics drivers and a variety of OpenGL/Vulkan titles.
In preparation for the Radeon RX 590 launch this week, I’ve been re-testing my available graphics cards on the latest AMD/NVIDIA drivers and newest kernel (unlike some Windows sites that may regurgitate […] Continue Reading…
There was a time when deploying software was an event, a ceremony because of the difficulty that was required to keep this consistency. Teams spent a lot of time making the destination environments run the software as the source environment. They thereafter prayed that the gods kept the software running perfectly in production as in development.
With containers, deployments are more frequent because we package our applications with their libraries as a unit making them portable thereby helping us […] 6092011051
The Spectre/Meltdown Performance Impact On Linux 4.20, Decimating Benchmarks With New STIBP Overhead
As outlined yesterday, significant slowdowns with the Linux 4.20 kernel turned out to be due to the addition of the kernel-side bits for STIBP (Single Thread Indirect Branch Predictors) for cross-HyperThread Spectre Variant Two mitigation. This has incurred significant performance penalties with the STIBP support in its current state with Linux 4.20 Git and is enabled by default at least for Intel systems with up-to-date microcode. Here are some follow-up benchmarks looking at the performance hit with the […] Continue Reading…
