Hi, I am working on enabling the KEXEC on PPC440 chipsets. To debug my patches, I would like to use the Qemu. The only available PPC440 support in Qemu is for the ppc-virtex. (Thanks for adding the support).
I was trying to use the default image provided at http://wiki.qemu.org/download/ppc-virtexml507-linux-2_6_34.tgz However I cannot get the network up for the board to use the nfs root file system. ---- PPC 4xx OCP EMAC driver, version 3.54 TCP cubic registered NET: Registered protocol family 17 VFS: Unable to mount root fs via NFS, trying floppy. VFS: Cannot open root device "nfs" or unknown-block(2,0) Please append a correct "root=" boot option; here are the available partitions: Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(2,0) --- I tried using a different dtb based on virtex440-ml507.dts, but the qemu complains : [suzie@suzukikp ppc-virtex-ml507]$ ./qemu-run.sh Unable to copy device tree in memory Is there something I can do to get the networking up ? I think this may need to be fixed in the dtb. Or is there any other mechanism to use a different file system ? ( I have the tool chain to build the kernel etc) Thanks Suzuki
