I successfully installed the evbmips64el port on gxemul but was unable to install it on qemu. Trying to boot it on qemu takes me to the 'db>' prompt. Here's the output and backtrace:

>How-To-Repeat:
Build evbmips64el from source and then launch it from qemu (replace the paths relative to your system):

qemu-system-mips64el -cdrom /extra/evbmips64/distrib/evbmips/cdroms/installcd/NetBSD-7.99.71-evbmips-mips64el.iso -hda /extra/evbmips64.img -kernel /extra/evbmips64/releasedir/evbmips/installation/netbsd-INSTALL_MALTA64 -nographic -M malta

(I've decompressed the kernel)

 this sounds like a qemu bug.  the hardware shouldn't be using
 irq 0.  i think it would be best to file a PR against qemu.

 Feedback from qemu developer Aurelien Jarno:

 I haven't look in details, but it looks like that the PCI initialization
 hasn't been done. This should be the responsibility of the firmware, but
 the Malta emulation doesn't use any firmware when booting with -kernel.
 It works with the Linux kernel because there is some fixup code which
 does the work if it hasn't been done in the firmware. See:


 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/a=
 rch/mips/pci/fixup-malta.c

 One option would be to implement the same on the NetBSD side. The other
 option is to use YAMON or U-Boot to load the NetBSD kernel.

 Aurelien
