i have smp support compiled into my kernel, an still, i never see anything on the HT'd cpu. i realize that most ppl believe that the HT portion of the technology was just a bunch of smoke blown up our butts by intel, but windows sure loves to bounce that extra cpu graph around a lot. below is just a snip of my top window, but as far down as i can stretch my 1280x1024 screen, its all "cpu 0" processes, even while compiling. last pid: 16214; load averages: 0.75, 0.35, 0.17 up 1+00:37:34 09:43:04 114 processes: 2 running, 112 sleeping CPU states: 34.2% user, 0.0% nice, 15.4% system, 0.4% interrupt, 50.0% idle Mem: 202M Active, 456M Inact, 232M Wired, 860K Cache, 110M Buf, 97M Free Swap: 983M Total, 983M Free PID USERNAME THR PRI NICE SIZE RES STATE C TIME WCPU COMMAND 8805 root 1 8 0 35880K 35552K wait 0 0:11 15.64% ruby18 15952 root 1 8 0 1224K 1112K wait 0 0:00 8.00% make 15925 root 1 8 0 1224K 1112K wait 0 0:00 3.59% make 656 jhorne 1 96 0 303M 53372K select 0 8:25 2.69% Xorg 742 jhorne 1 96 0 12632K 8252K select 0 16:42 1.03% gkrellm 1337 jhorne 1 96 0 29092K 21276K select 0 0:02 0.78% kdeinit 732 jhorne 1 96 0 30700K 22904K select 0 1:21 0.10% kdeinit 293 root 1 96 0 1260K 684K select 0 0:24 0.05% moused 752 jhorne 1 96 0 25780K 17952K select 0 7:07 0.00% kdeinit 738 jhorne 4 20 -76 14012K 8132K kserel 0 1:34 0.00% artsd 758 jhorne 1 96 0 31820K 21544K select 0 1:24 0.00% kdeinit 720 jhorne 1 96 0 30724K 22796K select 0 1:13 0.00% kdeinit 695 jhorne 1 96 0 3532K 2012K select 0 0:41 0.00% gam_server 728 jhorne 1 96 0 25596K 17556K select 0 0:12 0.00% kdeinit dmesg shows that freebsd sees the other cpu...
