Besides being curious about the Steam Survey results for indicating the size of the Linux gaming marketshare as an overall percentage, one of the interesting metrics we are curious about each month is the AMD vs. Intel CPU marketshare for Linux gaming. AMD has been on quite an upward trajectory among Linux gamers/enthusiasts in recent years not only for their Radeon graphics cards with their popular open-source driver stack but their Ryzen CPUs have become extremely popular with Linux users. With the new Steam Survey results for June, AMD CPUs are found on nearly 70% of Linux gaming systems polled by Steam...

This week NVIDIA and their AIB partners began shipping the GeForce RTX 4060 graphics card with pricing starting out at $299 USD. Like the recently-launched Radeon RX 7600, the RTX 4060 is geared mostly for 1080p gaming but how does it compare against the RX 7600 that is priced starting at $249? Here are some initial Linux gaming benchmarks of the GeForce RTX 4060 against the Radeon RX 7600.

An independent developer has posted an open-source Linux driver for review in order to handle the Apple Studio Display backlight control under Linux. The Apple Studio Display uses a Thunderbolt (DP) interface for display but lacks any hardware controls. Thus a USB interface is used by the monitor for controlling attributes like the display backlight brightness...

Currently most avionics real-time operating systems for airplanes are proprietary and very specialized for safety assurance reasons. Using Linux though and other open-source software would ease development, open more developers to being able to work on said avionics platforms, have much better documentation, and lower other barriers, but there are challenges currently involved...

Linux creator Linus Torvalds doesn't write as much actual kernel code these days as he used to. These days he's often busy overseeing the upstream kernel development community with reviewing code, managing releases, and chiming in on mailing list discussions. Once in a while though he gets down and dirty with some low-level kernel hacking just as he's done now for Linux 6.5 with improving the user-mode stack expansion code...

Whatever Intel ends up doing, their Linux engineers continue pushing Meteor Lake-S related code into the Linux kernel...

Today is a very fun and interesting round of benchmarking... Recently Supermicro sent over their Hyper SuperServer SYS-221H-TNR and Intel supplied the Xeon Max 9468 and Xeon Max 9480 for finally being able to benchmark Xeon Max processors, the Sapphire Rapids parts featuring 64GB of HBM2e memory. For this initial benchmarking article is a look at the Xeon Max 9468/9480 dual socket performance when running in HBM-only mode and HBM-caching mode for showing some of the workloads where Xeon Max can deliver significant uplift compared to when running in flat (1LM) mode without assigning anything to the HBM memory for seeing the impact when the specialized memory goes unused.
