Btw, The approach I've taken (code to follow), was to register reset functions that issues ioctls in a separate handler, that later calls all of them already in the vcpu-thread. So, no code movement, and thus, no races. reset code is responsible for most remote calls in qemu. One of the only ones we still have left is the gdb stuff. Do you have any suggestion to do that without the current on_vcpu mechanism? -- Glauber Costa. "Free as in Freedom" http://glommer.net "The less confident you are, the more serious you have to act."
