Hello, I'm trying to debug a 64 bits kernel (3.2) using qemu (with and without KVM support). The host is also 64 bits. Version of gdb I'm using is 7.1. To do that I simply start qemu like the following: $ qemu-system-x86_64 -kernel bzImage -append "root=/dev/sda1 console=ttyS0 3" -serial stdio

Hello, I'm trying to use qemu to emulate the ARM realview-pb-a8 and more specifically I'd like to boot using the SD interface. However it looks like some devices are not emulated at all on this platform. I added a couple of trace to see which one cannot be probed by the kernel and I got them: a
