Subject: [Qemu-devel] Is Little endian supported by Qemu -prep
Date: Thu, 07 Apr 2005 10:02:37 +0300 [thread overview]
Message-ID: <4254DB0D.6060509@co.inet.fi> (raw)
Still working on OS/2 PPC edition bootloading. I got patch to ppc_prep.c
from J Mayer to make it support non-continuous I/O map mode. It seemed
to work ok. But catched bug in the further code after line mfspr
r3,1008. I modified ppc_prep.c Processor version from 0x00080000 (g3)
to 0x00040000 (604) and problem was fixed. Now it crashes after code:
subfic r0,r0,-32690
mtlr r0
blr
(LR = ffef7f1e)
r0 was 0x00100130 to begin with
This error happens shortly after changinfg MSR state from 0x00000030
to 0x00000031 (change mode from Big-endian to Little endian) So might
Little-endian be reason why LR goes nuts?:)
