- Other early enablement work for next-gen Intel Panther Lake processors as well as Xeon Diamond Rapids processors.
- More AMD RDNA4 enablement work within the AMDGPU and AMDKFD driver code.
- Improved hybrid CPU capacity scaling for Intel Lunar Lake CPUs and other future processors with P/E cores but no HT/SMT.
- The Intel Linux graphics driver is finally able to report fan speeds for graphics cards.
- Initial Raspberry Pi 5 support within the mainline Linux kernel has finally landed!
