I see you are working on OpenRISC. Would you be able to help
me improve its wiki page?

http://wiki.qemu-project.org/Documentation/Platforms/OpenRISC

Right now there isn't much information on OpenRISC here. I'm
hoping to make it a lot useful to anyone who is interesting in this
platform.

Would you know of any links to software that works in OpenRISC?

Pictures of the OpenRISC target running anything would be great also.

What is your suggested command-line for using OpenRISC?

If you have any suggestions on how to improve the page place don't
hesitate to let me know.

Thank you.

Hi Richard, G 3,

I am not sure if Richard has the time for this.  But I kind of got him
started back on the openrisc work, it would be my fault to burden him
with even more work :).  Also, I was helping to do some tests so I have
some example commands.

I don't have a lot of time, but I think I can help to update the above.
Probably Richard and I could work together?

I was recently working on updating the openrisc page

  http://openrisc.io

I think I could link between the two for toolchain compile guides and
software guides (i.e. debugging and linux).

Richard what do you think?

Probably the most beneficial thing that we can do is create a kernel+initrd 
that boots into a busybox root shell.  Similar to the other test images that we 
have at

I posted a test image to the wiki

 http://wiki.qemu-project.org/Testing/System_Images

However, someone on the #qemu irc room mentioned its not ideal to post
any images on the wiki and existing images should be taken down due to
copyright issues.  I don't quite follow, should we be concerned?

Also, I did start adding some commands to the wiki, any feedback
appreciated.

If this is a Linux test image, it should be fine. Could we add a link  
to the test image to the wiki page?

Thank you so much for all your work. The wiki page looks great. For  
the maintainer, is Jia Liu still maintaining it? I never received a  
reply from him.  Would you be interested in being a maintainer?

This line in the wiki doesn't sound right:
"To get good traces you can also add the following, this will output  
trace info the a file z"

Maybe this:
"To get good traces you can also add the following, this will output  
trace info to the file z"

If z is a file, I really suggest renaming it to something more  
descriptive.

Thank you.

No worries, I just copied the commands from my history, some were sent
from Richard.  I hope they can help others in the future.

Last time I sent a patch Jia Liu also asked me to be maintainer,  I
added myself for now.  I am sure there are more qualified people like
Richard, but Ill try to help where I can.

Done.  If I do any more cool things with qemu I will post them to the
twiki.  Also, Ill try to link back to any docs I/we put on openrisc.io.

BTW, for now the image at 'Testing/System_Images' is hosted on my
server.  Would it be possible for someone to move it to the wiki or a qemu
server?  The link I posted should be up most of the time, but its not
something I would give any 9's of up time.

I think that someone is confused.  All of those testing images are open source.

Thanks for building it!

[Qemu-devel] [PATCH 00/22] target/openrisc updates

[Richard Henderson]

The bulk of this patch set is 2-3 years old, and was mostly
reviewed by Bastian Koppelmann.  But it languished because
there were reports of it not booting kernel images, and I
had problems putting together a set of tools that could even
build a kernel.

The OpenRISC community has picked up activity recently,
with Stafford Horne upstreaming some of the compiler tools.
He has even done some testing for me of this patch set.
