AMD Developing New Heterogeneous CPU Core Driver For Linux Systems
AMD for months has already been working on heterogeneous core topology optimizations for Linux within the AMD P-State CPUFreq driver and other heterogeneous CPU topology improvements for dealing with Ryzen systems sporting a mix of 'classic' (full) cores with the denser 'C' cores
A healthy chunk of that is the new documentation that explains the classic and dense cores, the amd_hfi driver handling, and how the thread classification and ranking is carried out. Thus at the earliest we're likely looking at the driver potentially being ready for Linux v6.13 that in turn will reach a stable release in early 2025. I'll be running some benchmarks on my side with these new AMD heterogeneous core driver patches to see if they help further enhance the likes of Strix Point on Linux.
