Among the early pull requests sent out already ahead of the Linux 6.2 merge window opening next week is a change to enable "-funsigned-char" by default for Linux kernel builds. In preparation for this compiler flag change several fixes have already landed along with a lot of early testing, so any fallout is hoped to be minimal...

Back in October AMD sent out their initial Zen 4 "znver4" enablement for the GCC compiler. That initial Zen 4 support was since merged for GCC 13 but that initial enablement carried over the cost tables from Zen 3 and didn't do much in the way of tuning but rather just flipping on the new instructions supported by the Ryzen 7000 series and EPYC 9004 series processors. Today there is finally some juicy tuning patches being sent out for GCC...

Back during the summer once Asahi Linux introduced initial Apple M2 SoC support I ran many Apple M2 Linux benchmarks including a look at how the M2 competes with AMD and Intel laptop processors. With months having passed since then and the Apple M1/M2 Linux support has continued to advance upstream as well as more work hitting the Asahi Linux tree, here is a fresh look at where the performance of the M2 is currently at compared to that initial at-launch support.

Released this morning is Intel IGC 1.0.12504.5 for Linux and Windows systems as the newest version of the open-source Intel Graphics Compiler. As the first tagged update in nearly two months, IGC 1.0.12504.5 is a big one...

As was expected following an uptick in kernel patches mid-to-late in the cycle, Linus Torvalds today opted to issue Linux 6.1-rc8 rather than going straight to the stable release for Linux 6.1, which is also expected to serve as this year's Long Term Support (LTS) kernel...

The past few months there has been a change proposal discussed around adding "-fno-omit-frame-pointer" to the default compilation flags for packages being built for Fedora Linux. Adding this option would improve the profiling/debug-ability of the packages but with possible performance implications. The Fedora Engineering and Steering Committee (FESCo) has now rejected this contentious change proposal...

With November now in the books, here is a look back at the most popular original open-source/Linux content on Phoronix from the 245 original articles written by your's truly over the past month. It was an extremely exciting month given the launch of the AMD EPYC 9004 "Genoa" processors with up to 96 cores per socket, AVX-512, and with all of the improvements meant outright insane generational improvement and currently slaughtering the competition. The Linux 6.1 kernel nearing the limelight, early development work on Linux 6.2, and the continued embracing of the Rust programming language by the open-source ecosystem all made for an interesting November...

That is until a developer finally stepped up and has pending support for the "TearFree" option...

Last month when the Intel Arc Graphics A750 and A770 reached retail availability, there was open-source support available for Linux users assuming you were on a new enough kernel and Mesa release plus having to activate the preliminary/experimental hardware support flag. In the time since the open-source Intel dGPU Linux graphics driver support has continued to mature and with the upcoming Linux 6.2 kernel is where DG2/Alchemist graphics have been promoted to stable / supported out-of-the-box. Given this milestone and the upstream Mesa code for the Intel ANV Vulkan and Iris Gallium3D drivers continuing to mature, here are some fresh benchmarks of the Intel Arc Graphics A750/A770 under Linux.
