Hi Hoa, Thanks so much for your help! I just tested it and it worked perfectly.
Another question is that based on your test here(http://www.gem5.org/documentation/benchmark_status/#spec-2017-tests <http://www.gem5.org/documentation/benchmark_status/#spec-2017-tests>), gem5-20 along with linux-5.4 is able to support 2 O3 CPUs with the protocol MESI_Two-Level. But I cannot boot it successfully. It just stop running further at one point but not terminated either. The command I run: build/X86/gem5.opt configs/example/fs.py --kernel=vmlinux-5.4 --disk-image=ubuntu-18.04.img --num-cpus=2 --ruby --cpu-type=DerivO3CPU Output: warn: instruction 'sgdt_Ms' unimplemented warn: x86 cpuid family 0x0000: unimplemented function 6 warn: x86 cpuid family 0x0000: unimplemented function 6 warn: x86 cpuid family 0x0000: unimplemented function 6 warn: Address 0xffffffc0 is outside of physical memory, stopping fetch warn: Address 0xffffffc0 is outside of physical memory, stopping fetch warn: instruction 'wbinvd' unimplemented warn: x86 cpuid family 0x0000: unimplemented function 6 warn: x86 cpuid family 0x0000: unimplemented function 6 warn: x86 cpuid family 0x0000: unimplemented function 6 hack: Assuming logical destinations are 1 << id. warn: x86 cpuid: unknown family 0x4000 warn: instruction 'fwait’ unimplemented And the output at the VM terminal: [ 0.383486] check: Scanning for low memory corruption every 60 seconds [ 0.383705] Initialise system trusted keyrings [ 0.383705] Key type blacklist registered [ 0.383705] workingset: timestamp_bits=36 max_order=17 bucket_order=0 [ 0.388387] zbud: loaded [ 0.389302] squashfs: version 4.0 (2009/01/31) Phillip Lougher [ 0.389737] fuse: init (API version 7.31) [ 0.389737] *** VALIDATE fuse *** [ 0.389737] *** VALIDATE fuse *** [ 0.389737] Platform Keyring initialized [ 0.393641] Key type asymmetric registered [ 0.393641] Asymmetric key parser 'x509' registered [ 0.393641] Block layer SCSI generic (bsg) driver version 0.4 loaded (major 244) [ 0.393641] io scheduler mq-deadline registered [ 0.393641] shpchp: Standard Hot Plug PCI Controller Driver version: 0.4 !!!
