Last month I posted benchmarks showing the performance when using the new 3D V-Cache Optimizer driver on Linux using the flagship Ryzen 9 9950X3D. This optimizer driver allows tuning the "amd_x3d_mode" for indicating your preference for the CCD with the higher frequency or larger cache size. For some additional insight into the 3D V-Cache Optimizer driver performance impact on Linux, here are benchmarks looking at the difference while using the AMD Ryzen 9 9900X3D.

Two separate patch series updated this week for the open-source Intel Linux graphics driver stack is the still-ongoing work around the DRM sharpness property for the new adaptive sharpening filter with Xe2 Lunar Lake graphics and then separately is the work to bring VRAM Self Refresh (VRSR) over to the modern Xe kernel driver...

Going back to 1972 is the General Purpose Interface Bus (GPIB, a.k.a. IEEE-488) as a parallel interface bus developed by HP. GPIB pre-dates the Linux kernel itself while it wasn't until last year that the GPIB driver subsystem was added to the Linux kernel's staging area with GPIB still seeing some use by scientific equipment and other devices. For Linux 6.15, the GPIB code has seen a thorough round of code clean-ups and improvements...

The CPUIdle Menu governor also received some performance tuning worth mentioning...

Back in late February when Framework announced a slew of new hardware products they will be launching next year, they also teased the Framework Laptop 12 as a new, smaller laptop while continuing to be modular/upgradeable. They announced today that Framework Laptop 12 pre-orders will begin next week...

Last week I posted some initial GNOME 48 and KDE Plasma 6.3 desktop gaming benchmarks on Ubuntu 25.04 beta for looking at the performance of those two leading desktop options for this upcoming Ubuntu Linux release. Both GNOME and KDE under Wayland were outperforming KDE on X11 (and GNOME on X11 wasn't even working due to bugs). Some Phoronix readers questioned though whether the Wayland advantage on GNOME/KDE was due to those desktops losing focus on X11 support or if they are just too bloated. So for adding some additional context, here are some graphics/gaming benchmarks on the same system hardware/software when adding in the Xfce 4.20 and LXQt 2.1 X11 desktops.

This morning's Intel TDX update reminded me that I still hadn't gotten around to digging into the Kernel-based Virtual Machine (KVM) changes merged last week for the ongoing Linux 6.15 kernel merge window. Here is a look at the KVM changes this cycle that continue to be particularly heavy on Intel and AMD virtualization improvements...

Intel's original DG1 discrete GPU was principally a development vehicle on the path to DG2/Alchemist. It did appear with the Iris Xe Max laptop dGPU in very few configurations but surprisingly it's taken until now where the Intel Linux graphics driver is set to remove the experimental "force_probe" flag on these pre-Alchemist discrete GPUs...

Merged last week for the Linux 6.15 merge window were a big set of scheduler updates...

The Steam Survey results for February showed a 0.61% drop for Linux gaming marketshare following a 20.8% increase to the Chinese use, which was yet another month of such wild swings attributed to a large influx in Simplified Chinese survey respondents. The March results for Steam Survey were published this evening and show the Linux marketshare more than recovering now that the English survey results have shot back up...

While the first quarter is coming to an end, there has already been immense progress this year to the Wayland protocols and compositors along with associated Linux desktop software for embracing this alternative to legacy X11/X.Org. From HDR color management seeing much adoption this quarter to Wine Wayland becoming more viable and the large number of Wayland compositors maturing, it was a pretty incredible quarter...

Cloud Hypervisor began as an open-source Intel software project more than a half-decade ago with an emphasis on security and cloud deployments while leveraging the Rust programming language. With time its scope has broadened a lot as has its industry adoption.
