After I added "-cpu 34Kf", qemu would start normally again even with "-smp 2" option.
However, "cat /proc/cpuinfo" only shows 1 CPU. "uname -a" shows the following which seems to suggest the kernel is not SMP aware. Is there a kernel for malta with SMP support? Linux debian-mips 4.9.0-7-4kc-malta #1 Debian 4.9.110-3+deb9u2 (2018-08-13) mips GNU/Linux Thanks.
