My AMD processors have all v2 features except SSE4.1 and SSE4.2. They have SSE4a, introduced by AMD before Intel released its SSE4.1 and 4.2 standards. I've said this before (in other places) and will say it again here: the versioning used by Intel paints processors with broad strokes of the brush where in fact features are more finely grained than that. One can see one's processor "version" by cloning https://github.com/HenrikBengtsson/x86-64-level.git and altering it a littl= e to run under FreeBSD. I simply loaded the linux kld and altered the script to = read /usr/compat/linux/proc/cpuinfo. --=20 You are receiving this mail because: You are the assignee for the bug.=
