Hi Brad, I tried MOESI Hammer protocol with 4 processors. I am still getting an error: SMP: Processor 1 failed to start. Slave CPU 2 console command START SlaveCmd: restart FFFFFC0000310020 FFFFFC0000310020 vptb FFFFFFFE00000000 my_rpb FFFFFC0000018680 my_rpb_phys 18680 SMP: Processor 3 failed to start. Brought up 2 CPUs
My command line is ./build/ALPHA_FS_MOESI_hammer/m5.opt ./configs/example/ruby_fs.py -t --caches --l2cache -n 4 -b bodytrack Thanks for your help..
