Hi, Mark, could you just enumerate those test images, download
locations, etc. and whatever else is needed to reproduce the boot
processes in question - it would be useful not only for this patch
set, but for possible future work, wouldn't it?
Sorry in advance if that info in possibly in another message, and
was missed by me.
I've sent it to Mark off-list but here it is:

I was testing fulong2e with this kernel:
http://distfiles.gentoo.org/experimental/mips/livecd/loongson-2007.1/
running it as
qemu-system-mips64el -M fulong2e -serial stdio -net none -vga none \
-trace enable="pci*" -kernel gentoo-loongson-2.6.22.6-20070902 \
-cdrom debian-8.11.0-mipsel-netinst.iso
adding the cdrom proabably does not really matter and I could not find
corresponding gentoo iso so using a debian one, it's just useful to have
something on the ide bus and also -cdrom adds it to second channel
because if you test with something on first channel only it might work
as that uses IRQ14 anyway.
On pegasos2 I've used:
qemu-system-ppc -M pegasos2 -net none -serial stdio \
-vga none -device ati-vga,romfile=VGABIOS-lgpl-latest.bin \
-cdrom morphos-3.13.iso
then enter "boot cd boot.img" at the firmware ok prompt.
And also the same pegasos2 command with
-cdrom debian-8.11.0-powerpc-netinst.iso
and enter "boot cd install/pegasos" then I usually select 3 for rescue
mode which can get to a command prompt.
For more info on VGABIOS-lgpl-latest.bin and pegrom.bin needed for
pegasos2 see Pegasos2 emulation subproject on my http://qmiga.osdn.io/
page.
The fulong2e probably still has some problem correctly emulating pci
devices becuase without -net none -vga none the kernel panics, I have no
interest trying to debug and fix that, I only using fulong2e to
cross-check changes needed for pegasos2. It could also be that the kernel
being experimental have some problems, I can't test if it works on real
hardware.
