Dear Ali, Thank you very much for the response. I haven't modified the simulator, but only configured some path for FS configuration. I'm using the stable version of gem5 up to date, and FFT in splash2 benchmark suit to test. All the configuration under L2 cache configuration is under the direction of gem5.org site.
I have diffed the terminal output under m5term, and there is slight difference as followed. I'm not sure whether it help to diagnose. terminal under l2 cache: ------------------------------- VFS: Mounted root (ext2 filesystem) readonly. Freeing unused kernel memory: 208k freed init started: BusyBox v1.1.0 (2007.03.04-01:07+0000) multi-call binary mounting filesystems... EXT2-fs warning: mounting unchecked fs, running e2fsck is recommended loading script... terminal under l3 cache: ------------------------------- List of all partitions: 0300 1433376 hda driver: ide-disk 0301 1433344 hda1 0340 1433376 hdb driver: ide-disk 0341 1433344 hdb1 No filesystem could mount root, tried: ext3 ext2 Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(3,1) Chao On Fri, Jul 12, 2013 at 12:39 PM, Ali Saidi <[email protected]> wrote: > ** > > Have you made any changes to the simulator?
