Dear qemu developers
I built an image for e5500 cpu with yocto and run with qemu ppce500 machine:
qemu-system-ppc64 -nographic -M ppce500 -cpu e5500 -kernel uImage -initrd
core-image-minimal.rootfs.ext2.gz -append 'root=/dev/ram rw'
It works well, but as the emulated guest is in idle state, in the
Hi Philippe, Thank for your email
I investigated your advice,
first checked the CPU's programmer's reference manual and it has wait for
interrupt instruction.
then to check what instructions are executing I run this command:
qemu-system-ppc64 -nographic -M ppce500 -cpu e5500 -kernel uImage
-sin
Thank a lot Peter and Philippe
