[Qemu-devel] [PATCH] PPC: Support flags -boot, -uuid and -kernel using fw_cfg
Sun, 21 Dec 2008 21:46:10 +0200
These two patches (Qemu/OpenBIOS) add support for giving OpenBIOS/PPC
a boot device with -boot command line flag, use a UUID (print only)
and call a preloaded kernel. These are passed from Qemu to OpenBIOS
using the firmware configuration device and NVRAM.
Using the -boot switch works, but I can't boot anything yet so it's
not very well tested. UUID works, but it's not added to the device
tree. Kernel crashes after the first instruction, maybe the memory
size probe corrupts memory.
