At this time, qemu/tls.h is really just for cpu_single_env, so I think this patch should be applied together with the bsd-user patches that need it. > As an aside, an abstraction was recently proposed for Open vSwtich that > can use any of _Thread_local, __thread, or pthread_getspecific() which > may make a convenient reference for someone wishing to implement one of > the TODOs: http://openvswitch.org/pipermail/dev/2013-June/028665.html I and Stefan Hajnoczi have almost the same idea implemented in QEMU (except that get_foo() returns a pointer to the variable). But pthread_get/setspecific would be too slow for cpu_single_env, so we're just switching to __thread for cpu_single_env (for Linux in our patches, but you can add FreeBSD too once it's needed). Paolo
