Hi ! i am trying to emulate mips on Qemu but at some point the kernel is
getting a hard interrupt from Qemu which the kernel is not able to
understand and makes it a spurious interrupt.Can any one tell me that which
part of the Qemu code will tell me the source or any information about that
hard interrupt so i can deal with that?
Help me plz.
Thanks

Hi,
A good starting point is to look at:
target-mips/helper.c: do_interrupt()
These are also useful:
target-mips/cpu.h: cpu_mips_hw_interrupts_pending()
hw/mips_int.c
Cheers,
Edgar
