To: qemu-devel
A grab-bag of fixes:
- Report FP registers for the MIPS gdb stub
- Implement the set_thread_area syscall for MIPS user emulation
- Implement the set_tid_address syscall for user emulation
- Correct 64-bit / 32-bit issues in do_socketcallwrapper
- Emulate rdhwr for MIPS usermode
- Correct double-precision cvt opcodes
- Save the PC before generating a CpU exception
The user mode fixes let me emulate NPTL single-threaded binaries. The CpU
fix prevents random crashes and corruption in hard float binaries in system
emulation mode. And the cvt fixes correct most of the failures running
the GCC testsuite in user emulation.
This is enough to run debian-installer inside of qemu, if you are very
very patient.

[Replying to the list in case this is helpful for others.]
./obj/mips-softmmu/qemu-system-mips \
-kernel /space/linux/qemu/mips-obj/arch/mips/boot/vmlinux.bin \
-nographic -initrd nightly-initrd.gz \
-append "console=ttyS0 root=/dev/ram" -hda new-image.img
You will need:
- the patch that Aurelien posted recently to set rd_start/rd_size
- My collected fixes
- A usable kernel .config, the attached may help

I have also made precompiled kernels:
http://people.debian.org/~aurel32/mips-qemu/
It is also possible to extract vmlinux with dpkg -x. When the system is

And you can also use this quick and dirty howto:
