All,
I am booting Ubutnu on A72 cores and the command is as given below.
./build/ARM/gem5.fast ./configs/example/fs.py
--kernel=${M5_PATH}/binaries/vmlinux.aarch64.20140821
--disk-image=${M5_PATH}/disks/aarch64-ubuntu-trusty-headless.img
--dtb-filename=${M5_PATH}/binaries/vexpress.aarch64.20140821.dtb
--machine-type=VExpress_EMM64 --caches --l2cache --l3cache --l1d_size=32kB
--l1i_size=48kB --num-cpus=2 --num-clusters=4 --cpu-type=a72_detailed
--mem-size=2048MB --mem-type=DDR3_1600_x64 --sys-clock=1100MHz
--cpu-clock=2200MHz
However, once the Ubuntu is booted, lscpu command returns the following. It
appears to me the num_cpu and num_clusters are not simulated properly! Can
someone please confirm and/or let me know what's the remedy?
$lscpu
Architecture: aarch64
Byte Order: Little Endian
CPU(s): 4
On-line CPU(s) list: 0,1
Off-line CPU(s) list: 2,3
Thread(s) per core: 1
Core(s) per socket: 1
Socket(s): 2
