Bug#1026336: linux-image-amd64: Please set CONFIG_INTEL_HFI_THERMAL=y
Package: linux-image-amd64
Version: 6.0.3-1~bpo11+1
Severity: wishlist
Please consider setting CONFIG_INTEL_HFI_THERMAL=y for amd64 kernels going forward, to enable Intel's Hardware Feedback Interface.
Modern Intel CPUs (12th and 13th gen and newer) use a mix of more powerful performance cores and weaker efficiency cores, and the HFI is a key component in allowing the kernel to schedule tasks across both types of cores intelligently (similar to the Thread Director in Windows 11).
Work on scheduling and thermal efficiency in mixed Intel CPUs is ongoing in 6.x, and enabling the HFI is necessary to make use of those improvements.

Thanks for your work!
