OpenBSD disables Intel's hyperthreading due to security concerns
So... they "strongly suspect" (but don't know and haven't shown) there may be a Spectre-class bug enabled by current HT implementations and improving their scheduler is hard, so they'll pre-emptively disable HT outright on Intel CPUs now and others in the near future?<p>I'm not an OpenBSD user (and glad for it, if this is anything to go by), but I'm curious - is this really how they operate, or does this decision stand out?
