Linus Torvalds has announced the release of Linux kernel 7.3-rc1, featuring a significant amount of code contributions from AMD's GPU driver updates, which account for about a third of the changes.
Linus Torvalds has released the Linux kernel 7.3-rc1, marking the closure of its merge window. This release is notable for the sheer volume of changes, with 15,267 commits making it the second busiest merge window ever, as reported by LWN. The key highlight here is the substantial contribution from AMD's graphics driver updates, which account for roughly a third of the total changes.
As detailed by Phoronix, the AMD kernel graphics driver alone adds a whopping 6.5 million lines to the kernel, which now approaches 41 million lines in total. This is primarily due to the inclusion of new hardware IP blocks for upcoming graphics hardware, particularly the DCN 6.0 register files. Linus himself pointed out that this release is "big as an actual diff" largely because of AMD's massive GPU register dumps, which are typically loaded with C header #defines for hardware definitions.
For engineers working with AMD hardware, this release brings both opportunities and challenges. The new code supports the latest generation of AMD graphics hardware, promising enhanced performance and capabilities. However, it also means that those maintaining systems with AMD GPUs will need to be prepared for the accompanying complexity and potential integration issues that such a large codebase can introduce.
While the size of the release is undeniably large, it's a testament to the ongoing expansion and evolution of the Linux kernel to support a diverse range of hardware. Sysadmins and developers should pay close attention to the changes in this release, particularly those relying on AMD GPUs, as it may necessitate updates to system configurations and testing procedures to ensure compatibility and stability.
