[Qemu-devel] running (open) solaris on sparc32

[Markus Schiltknecht]

Hi,

the qemu documentation states about sparc emulation: "... Please note 
that currently NetBSD, OpenBSD or Solaris kernels don't work."

What's needed to get Solaris to word? Or any of the BSDs?

Regards

Markus

There are a number of bugs in OpenBIOS, and at least one in qemu.
Your best bet is to check the OpenBIOS mailing list, where I've
discussed a number of the OpenBIOS issues.

OpenBIOS for Qemu was developed against Linux, which does not need too much 
from the BIOS. Other kernels are much more picky, but basically debugging 
should do it. Just try one, see where it fails, find the relevant lines in 
the source and fix the bug...

Does this help ? patch against target-sparc/op.c rev 1.24:

The SPARC Architecture Manual version 8 says on p107, "The shift count
for these instructions is the least significant five bits of r[rs2]".
