New Revision: 34854
Changeset: http://dev.haiku-os.org/changeset/34854/haiku
Modified:
haiku/trunk/src/system/boot/platform/openfirmware/arch/ppc/arch_start_kernel.S
Log:
Patch by Andreas Faerber:
* The kernel's _start entry function expects now a second argument, the
current CPU index. The PPC boot loader didn't initialize GPR4, passing
its second argument, the kernel entry address, as CPU index, causing
smp_cpu_rendezvous() to loop forever. This fix gets the PPC boot to a
kernel debug prompt. The CPU index is currently fixed to 0.
Thanks a lot!
