Hello! Are you are just testing host_mips qemu? I have been doing the same work two or three month ago on a mips + linux system. But, it have some bugs however. It is for qemu 0.6.1 refer to qemu-irix.patch at first. And yesterday, I made a qemu 0.9.0 patch. It seems working(only target-i386). In order to handle relocation symbol, I writed a little tool named op_mips.c. This tool is the key of my patch. host detail: cpu: loognson 2E(mips compatible, little endian) os: debian linux 4.0 kernel: linux 2.6.18 gcc: 3.4.6 glibc: 2.3.6 test: in full system mode: can run windows 98 or linux(x86) in user mode: can run some i386 elf programs except wine! bugs: In user mode, it catchs a SIGSEGV when launching a windows PE program. I have been trying to solve this problem a long time. But unfortunately, I failed. I wondered if you could give me some help about qemu + wine. And hope new qemu release supply host_mips soon. There is the patch: qemu-0.9.0-loongson.patch Thanks. Peng Jun
