I am planning on some changes in head and would like to see if people use the following features: - machdep.hyperthreading_allowed tunable and sysctl - machdep.hlt_logical_cpus tunable and sysctl - mp_watchdog kernel option If you are using any of the above, please let me know - better via a private reply: - which exactly of the mentioned above features you use - please make distinction between use of tunables and sysctls - tell for what you use the feature - provide overview of your hardware, which scheduler you use and intended purpose of the system
Whatever you do, please leave at least some way (at least a tunable) to enable/disable HTT - some workloads are better with, and some without it, and some BIOSes are unreliable in enabling/disabling it :)
