It works with -cpu 34Kf, but why cpuinfo display MIPS 34Kc? I notes the smp based on kvm implement, but there do not have kvm implement under target-mips? how this smp implement? Is there any document record the QEMU MIPS smp internal?
Does QEMU for MIPS target support FPU, SIMD instruction? cat /proc/cpuinfo system type : MIPS Malta machine : Unknown processor : 0 cpu model : MIPS 34Kc V0.0 FPU V0.0 BogoMIPS : 875.72 wait instruction : yes microsecond timers : yes tlb_entries : 16 extra interrupt vector : yes hardware watchpoint : yes, count: 1, address/irw mask: [0x0ff8] isa : mips1 mips2 mips32r1 mips32r2 ASEs implemented : mips16 dsp mt shadow register sets : 16 kscratch registers : 0 core : 0 VCED exceptions : not available VCEI exceptions : not available processor : 1 cpu model : MIPS 34Kc V0.0 FPU V0.0 BogoMIPS : 841.31 wait instruction : yes microsecond timers : yes tlb_entries : 16 extra interrupt vector : yes hardware watchpoint : yes, count: 1, address/irw mask: [0x0ff8] isa : mips1 mips2 mips32r1 mips32r2 ASEs implemented : mips16 dsp mt shadow register sets : 16 kscratch registers : 0 core : 1 VCED exceptions : not available VCEI exceptions : not available On Fri, Nov 8, 2013 at 12:13 AM, Edgar E.
