AMD Ryzen 9 3900XT CPUFreq Governor Comparison With Linux 5.9

One of the most frequent questions received at Phoronix in recent times is whether the "schedutil" governor is ready for widespread use and if it can compare in performance to, well, the "performance" governor on AMD Linux systems. Here are some benchmarks of an AMD Ryzen 9 3900XT using the latest Linux 5.9 development kernel in looking at the performance differences between the CPUFreq governor options of Ondemand, Powersave, Performance, and Schedutil.

Intel Engineers Begin Landing Open-Source Support For TDX, Intel Key Locker

Last month Intel published a whitepaper on TDX as Trust Domain Extensions as a means of better securing virtual machines. TDX allows for isolating VMs from the hypervisor and other non-VMM system software. Intel TDX builds off other recent work around MKTME memory encryption and other features. We are now beginning to see that software side support roll-out along with the also-new Key Locker instructions.

ADRIConf Remains The Primary GUI Control Panel For Managing Mesa OpenGL/Vulkan Drivers

While the Linux kernel graphics drivers and user-space OpenGL/Vulkan drivers expose a lot of options via sysfs on the kernel side and various environment variables and other tunables in user-space, when it comes to graphical control panels to manage these open-source graphics drivers on Linux there are several fragmented different options. For Mesa drivers, ADRIConf remains the leading option.

Open-Source Vivante Driver In Some Cases Outperforming Proprietary Driver

One of the less talked about open-source graphics drivers talked about is Etnaviv as the reverse-engineered, community-based driver providing OpenGL/GLES support for Vivante graphics IP. While it's still working towards OpenGL ES 3.0 compliance, its performance is currently in some cases competitive -- and even outperforming -- the Vivante proprietary driver.

FFmpeg Now Supports GPU Inference With Intel's OpenVINO

Earlier this summer Intel engineers added an OpenVINO back-end to the FFmpeg multimedia framework. OpenVINO as a toolkit for optimized neural network performance on Intel hardware was added to FFmpeg for the same reasons there is TensorFlow and others also supported -- support for DNN-based video filters and other deep learning processing.
