Hi All:
When I use –vio-9p with fs_bigLITTLE.py, 1 core the mount cmd was ok,
but more than 1 core, mount cmd will cause GEM5 crash
1core:
Gem5 cmd: ./build/ARM/gem5.opt --debug-flags=Exec -d
/home/l00515693/m5out configs/example/arm/fs_bigLITTLE.py --cpu-type=kvm
--kernel=vmlinux --machine-type=VExpress_GEM5_V1
--disk=expanded-aarch64-ubuntu-trusty-headless.img --caches
--big-cpu-clock=2.6GHz --little-cpu-clock=2.6GHz --big-cpus=1 --little-cpus=0
--mem-size=4GB --param 'system.realview.gic.gem5_extensions = True'
--bootscript=./test.rcS --vio-9p
Mount cmd in guest OS: mount -t 9p -o
trans=virtio,version=9p2000.L,aname=/home/l00515693/m5out/9p/share gem5 /mnt/9p
