It's a huge fail. One can apparently use speculative execution to create memory leaks. Some Intel processors without speculative execution - such as the Atom CPUs (including the embedded ones) - won't be affected, whereas the bigger, fancier i3, i5, i7, and Xeon processors will. It's unclear on which side of the line the Atom C2000 series (which had out-of-order but not speculative execution) will lie. Hopefully, when FreeBSD develops kernel patches to address the bug, it will exempt the unaffected processors. (I do a lot of work for embedded Atoms, and hope that they will not be slowed by patches intended for CPUs that actually need them.) --Brett Glass At 06:56 PM 1/2/2018, Joey Kelly wrote: >On Tuesday, January 02, 2018 08:52:27 PM Mike Tancsa wrote: > > I am guessing this will impact FreeBSD as well ? > > > > http://www.theregister.co.uk/2018/01/02/intel_cpu_design_flaw/ > >No way around it.
