mips64el magnum emulation broken

[Darkstar]

I'm trying to run the following:
qemu-system-mips64el --machine magnum [...]

The qemu binaries from (k)ubuntu work fine. "info version" shows
1.5.0 (Debian 1.5.0+dfsg-3ubuntu5)

When I try qemu 1.6.1 (compiled from source .tar.bz2), however, qemu only shows a black screen when starting.

I'm using the following BIOS:
https://mega.co.nz/#!gg0WBYpJ!MqTL3AFPjf4SJipdYgRK3HtFDIxA59YwI6ay5XI3KEc
which is the exact one linked to in the first guide below (can also be downloaded from there)

I'm following these guides on installing NT4 on qemu

Apparently, this is the fix (althoug I haven't tested it yet)

can someone confirm if it helps, and if so, apply it?

I just tried with the 1-line-patch referenced in the link above and it does indeed fix the black screen problem.

That's more of a workaround than a fix. Herve's patch:
 http://lists.gnu.org/archive/html/qemu-devel/2013-11/msg00296.html
is more the right approach I suspect.

(I'm not sure why his email didn't get recorded in this bug; it seems to have been on the cc.)

[Darkstar (michael-drueing)]

Yeah, that patch looks better, I was already wondering why nobody seemed to care since it's a pretty easy fix. I have a another bug I want to report with MIPS Magnum but it depends on this bug here so I'd rather wait until this is fixed before submitting the other bug report (or can I make a bug depend on another bug somehow?)

[Darkstar (michael-drueing)]

Will this be fixed in 1.7?

[Darkstar (michael-drueing)]

This bug is apparently fixed in 1.7.0 and can be closed
