Maybe now is a good time to do so :) This is very interesting topic to me. I just received few days ago = pandaboard, which is somehow successor of beagleboard and it is built on = TI OMAP4430 SoC. Main difference is that this one is dual core ARM Cortex-A9 so it needs = SMP support. I guess that so far there is no SMP in ARM implementation = on FreeBSD so I planed to spent some time on it.=20 Is there any work done so far on SMP side?=20 If not is there any wider interest to implement ARM MPCore in FreeBSD? Any other thoughts on this topic? Thanks, Damjan =20
