AMD engineer K Prateek Nayak recently uncovered that a ~20 year old chipset workaround in the Linux kernel still being applied to modern AMD systems is responsible in some cases for hurting performance on modern Zen hardware. Fortunately, a fix is on the way for limiting that workaround to old systems and in turn helping with performance for modern systems...

Up on the review block today is the Solidigm P41 Plus as a value-focused solid-state drive. Solidigm is the US company formed when SK Hynix acquired Intel's NAND/SSD business. Since forming Solidigm at the end of last year they have continued to sell products from Intel's existing SSD product line-up while last month they announced the P41 Plus as their first consumer solid-state drive of their own design. Recently I've been testing out the Solidigm P41 Plus 1TB and 2TB drives under Linux for seeing how these affordable QLC drives perform.

After the persistent work by developer Gert Wollny with a desire to improve the aging "R600g" driver that provides open-source OpenGL support for Radeon HD 2000 through HD 6000 series graphics cards, this Gallium3D driver in Mesa 22.3 will now use the NIR back-end by default...

Restartable Sequences "RSEQ" has been one of the nice additions to the Linux kernel in recent years and can allow for faster user-space operations on per-CPU data by providing a shared data structure ABI between each user-space thread and the kernel. RSEQ has been in the process of being extended to provide even more performance benefits...
