Re: [Qemu-devel] Sponsorship for QEMU Developers...

Marc,

here is an easy link to use:

ftp://ftp.win4lin.com/pub/oss/

oss stands for Open Source Software of course.

the qemu tarball is a CVS head snapshot from the 2/20/05; mergepro.patch 
gets applied to it to add our 3rd party stuff.  Basically what we do is 
enable loading a dynamic shared object as a "plugin", and export symbols 
back and forth as needed by supplying pointers to them both in vl.c and 
in our plugin.  We do not use any additional header files or anything 
like that in our closed source bits, since that would of course violate 
the GPL.  We mainly did this so that we could "replace" the 
initialization of certain built-in peripherals in QEMU with our own 
proprietary versions that live in the plugin.  To date, we replace the 
GUI ("display") and the IDE driver with our own home-grown versions. 
You will notice that all QEMU structures are passed in as void pointers 
back and forth, since we don't use any of the QEMU header files which 
define them.  We instead get and set only the members we are interested 
in by address in our plugin.

Note that this is fairly temporary.  We are working on making all of 
QEMU a shared library object itself, and adding accessors (get/set) for 
each QEMU structure type that are exported from the shared library. 
This would encapsulate the GPL'd code in a much cleaner way, and would 
let us avoid having to calculate addresses of members in our 
closed-source code when getting or setting data from structures.

Let me know if you have any additional questions.

Best regards,

Leo Reiter
