Are there any ARM emulators (eg qemu) that can start booting FreeBSD ARM - but then fail, because we're missing disk/console/net/etc support? Basically - I'd like to finish off the ARM/MIPS/PPC/Sparc emulation environment support for FreeBSD so people like Alan, Jeff and others who hack on things like the VM and memory allocation framework have a chance of testing on these platforms before they commit stuff that may break them.:) -adrian On 21 August 2013 16:43, Zbigniew Bodek wrote: > 2013/8/21 Adrian Chadd > >> Hi! >> >> I like your ARM work very much.
