On this first day of the Linux 6.14 merge window to kick off the new kernel development cycle there are a few pull requests around new AMD CPU features worth noting.
Building off yesterday's release of the Linux 6.13 kernel, GNU Linux-libre 6.13 is out today as this downstream kernel from FSF LA that strips out code pertaining to the ability to load non-free drivers/microcode and other elements not deemed within the standards of the Free Software Foundation, even when it means removing/disabling hardware support and features.
An engineer from AMD by way of their Nod.ai acquisition is seeking feedback from the community around what other Radeon graphics cards you would like to see supported by the ROCm support on Linux. This community wishlist extends to ROCm Windows support as well but at least there the HIP Rutime/SDK on Windows already supports more consumer GPUs than Linux.
After six release candidates going back to early December, it looks like Wine 10.0 stable will be ready to ship this week. This is largely as expected with the annual Wine stable releases tending to come around mid-to-late January. Here's a look at what's ahead for this stable release for enjoying Windows games and applications under Linux and other platforms.
Following the Bcachefs pull requests being rejected during the Linux 6.13 cycle by the kernel's Code of Conduct committee, the Linux 6.14 kernel cycle is kicking off with a big pull request so that the upstream kernel can get back into sync with the latest development code for this cycle. This pull also contains the last anticipated major on-disk format upgrade prior to the removal of the "experimental" flag for this copy-on-write file-system.

19 January
As anticipated the Linux 6.13 kernel was promoted to stable today with an on-time release and in turn also marking the start of the Linux 6.14 merge window. Linux 6.13 stable has plenty of fine features for this first major kernel release of 2025.
The pid_max tunable for the maximum number of process IDs allowed simultaneously was increased by default back in 2019 with systemd. But that increase breaks a long held assumption by some user-space software that pid_max or the process ID would not be greater than 65,535. To now better workaround such outdated user-space software, a set of patches for the Linux 6.14 kernel will allow adjusting the pid_max limit on a per PID namespace basis to help cope with such software hitting such artificial limits and without having to lower the overall system limit.
Ahead of the Linux 6.13 stable kernel expected to be released later today, there is a last minute fix for the EEVDF CPU scheduler.
