Hi folks,
I've looked at the physical guest memory allocation code (aka
qemu_vmalloc). Reason is that I need some way to map guest memory pages
to a second location in virtual memory. Thus I need a filehandle for
the memory, so I can mmap() pages from it somewhere.
I've seen there is a phys_ram_fd variable defined in exec.c. It isn't
used anywhere though. kqemu seems to have very simliar needs, there is
some code to back guest memory using a file in /dev/shm.
How about doing that *unconditionally*, not just for kqemu?
cheers,
Gerd
