The jemalloc memory allocator "malloc" implementation has been popular for HPC and server use down to desktop use in apps like Firefox. Jemalloc has proven over the years to be effective on delivering better performance and scalability while enjoying lower memory usage and less fragmentation than alternative malloc implementations. Meta recently announced that they are renewing their investment into jemalloc...

Since last week's Fedora 44 Beta release I have been testing out this upcoming Fedora Linux version on a few systems in the lab, most notably with the Framework Desktop powered by the powerful AMD Ryzen AI Max+ 395 "Strix Halo". Fedora Workstation 44 Beta has been looking nice and running stable albeit in some instances seeing lower performance at this point than Fedora Workstation 43 but overall in good shape.

The past several years Imagination Tech has been investing in an upstream and open-source DRM kernel graphics driver as well as a PowerVR Vulkan driver in Mesa. Their Mesa focus has exclusively been on the PowerVR Vulkan driver with the plans all along to use the Zink generic OpenGL-on-Vulkan implementation. With next quarter's Mesa 26.1 release, that goal is being realized with Zink now working nicely atop the PowerVR Vulkan driver for in turn achieving open-source OpenGL support on PowerVR...

The upcoming Linux 7.1 kernel cycle is set to retire UDP-Lite support. The UDP-Lite protocol allowed for partial checksums where potentially damaged/corrupted packets are still delivered to the application. Since the Linux 2.6.20 days there has been UDP-Lite support but the kernel is now set to retire it given breakage that has persisted for years and cleaning up the networking code can yield a performance advantage for non-UDP-Lite users...
