Hi,
Since the patch is a bit big, it will be available here in a few moments:
<http://cvs.mandrakesoft.com/cgi-bin/cvsweb.cgi/contrib-SPECS/qemu/>
Here are noteworthy changes:
* Translation cache must be mapped executable region. On AMD64 with newer
kernels, allocated pages in 64-bit processes are now R/W only, and not
executable. This is also true on other modern arches. I am probably
proceeding in an ugglish way but the idea is there.
* I imported newer i386-dis.c from gdb sources which knows about AMD64
instruction set. This has not been extensively tested beyond a simple run
for a hello/sha1 test program.
Bye,
Gwenole.
