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..
