I developed the Intel Thread Director (ITD) / Hardware Feedback Interfce (H= FI) device driver to obtain performance/efficiency information for each CPU cor= e, which was implemented to improve the performance of Intel hybrid architectu= re CPUs. (e.g. Raptor Lake (refresh), Alder Lake, LakeField processors) This driver simply obtains performance/efficiency information from the CPU = and stores it in the "cpu_group" struct data referenced by the ULE scheduler. However, since the ULE scheduler side is not yet supported, performance/efficiency cannot be improved by installing this driver at this time. I will try to modify the ULE scheduler side in the future, but I posted this driver first because it can be implemented independently of this driver and= it is difficult to modify the ULE scheduler. There are multiple patches. The purpose and application method of each is summarized in README-coredirector.txt file. Please merge it into the FreeBSD kernel source tree if possible. Also, I'm new to creating a FreeBSD's kernel patch. If you find any problems with the posting method, source code style, etc., I would be happy if you could tell me how to deal with them. Best regards. --=20 You are receiving this mail because: You are the assignee for the bug.=
