Hi, I am trying to simulate O3 CPU in FS mode, without ruby. However, the moment I specify more than 1 cores, i get the same error as mentioned in this thread. Any idea about how this could be resolved ?
**** REAL SIMULATION **** info: Entering event queue @ 0. Starting simulation... warn: Don't know what interrupt to clear for console. warn: instruction 'fxsave' unimplemented warn: instruction 'wbinvd' unimplemented warn: instruction 'wbinvd' unimplemented hack: Assuming logical destinations are 1 << id. panic: Unable to find destination for addr 0xa000000000001000 @ cycle 174196088592 [findPort:build/X86/mem/bus.cc, line 325] Memory Usage: 303284 KBytes I have booted with 2GB of memory. Any thoughts ? Thanks for your help.
