Greetings,

Just interested in an update of the current status. I built a fresh qemu from
the repository today and Im currently I get no output. 

Best wishes
Kristoffer

I do not catch 'no output' mean.  Could you explain it more?

FYI, here's the log how I built qemu-sh at Feb. 6th.

My mistake I did something wrong when I built it earlier, currently
it works somewhat. What doesnt work is keyboard,mouse and booting
from image file (seems like to bootstring isnt being aknowledged).

Current qemu sh4 system emulation does not support either usb host
or kernel boot command line.  You still need to apply some patches
to use those features.

Please check qemu-sh patch staging repository, which holds patches
for qemu-sh. README in it explains how to apply.
  http://git.kernel.org/?p=virt/qemu/lethal/qemu-sh.git;a=summary
To apply all them, you need to role back qemu to rev 6215, for now.


The patch for usb host is already posted to qemu-ml.  But I guess
patch for kernel boot command line for r2d is not yet posted.
Does anyone know who wrote the patch in qemu-sh staging repository?

My blocker is the lack of a working -append.  You have a git tree for a
collection of 5 patches, which then wants to invoke "quilt" to apply them. 
(Seems like overkill.)

At a guess, this seems like the patch that implements it is
staging/sh4-r2d-update-pci-usb-and-kernel-management.patch

> To apply all them, you need to role back qemu to rev 6215, for now.

No you don't, you just need a chainsaw and some duct tape...

I adjusted the above patch to apply to current qemu svn, and attached the 
result, but it didn't make -append work.  It's still using the hardwired one.

Any suggestions?  (Do I need to look at the other patches?  This one looked 
like it was _trying_ to fix the problem...)

Yoshii-san already turned on the chainsaw the day before yeterday. :)
  http://lists.gnu.org/archive/html/qemu-devel/2009-02/msg00727.html

And I guess, -append option is valid only if the kernel zImage does
not contain built in kernel arguments : the kernel in sh-test-0.1.tar.bz2
contains it. Here's the one without arguments, I hope it helps.

Yup, that fixed it.

Wow sh4 emulation is slow.  But working for me now. ;)

Which one have you tried?
svn://svn.sv.gnu.org/qemu/trunk@6587 works fine here.
Try
 ./configure --target-list=sh4-softmmu --disable-kqemu
 make
 sh4-softmmu/qemu-system-sh4 -M r2d --kernel kernel.kawa \
  --serial null --serial stdio 101M.img

Kernel is the one Kawasaki-san pointed in 
 http://lists.gnu.org/archive/html/qemu-devel/2009-01/msg01795.html
