2012-10-30linux-aio: use event notifiersPaolo Bonzini
Since linux-aio already uses an eventfd, converting it to use the EventNotifier-based API simplifies the code even though it is not meant to be portable. Reviewed-by: Anthony Liguori <anthony@codemonkey.ws> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2012-10-30aio: clean up now-unused functionsPaolo Bonzini
Some cleanups can now be made, now that the main loop does not anymore need hooks into the bottom half code. Reviewed-by: Anthony Liguori <aliguori@us.ibm.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2012-10-30main-loop: use aio_notify for qemu_notify_eventPaolo Bonzini
Reviewed-by: Anthony Liguori <aliguori@us.ibm.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2012-10-30main-loop: use GSource to poll AIO file descriptorsPaolo Bonzini
This lets us remove the hooks for the main loop in async.c. Reviewed-by: Anthony Liguori <aliguori@us.ibm.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2012-10-30aio: call aio_notify after setting I/O handlersPaolo Bonzini
In the current code, this is done by qemu_set_fd_handler2, which is called by qemu_aio_set_fd_handler. We need to keep the same behavior even after removing the call to qemu_set_fd_handler2. Reviewed-by: Anthony Liguori <aliguori@us.ibm.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2012-10-30aio: add aio_notifyPaolo Bonzini
With this change async.c does not rely anymore on any service from main-loop.c, i.e. it is completely self-contained. Reviewed-by: Anthony Liguori <aliguori@us.ibm.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2012-10-30aio: make AioContexts GSourcesPaolo Bonzini
This lets AioContexts be used (optionally) with a glib main loop. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2012-10-30aio: add Win32 implementationPaolo Bonzini
The Win32 implementation will only accept EventNotifiers, thus a few drivers are disabled under Windows. EventNotifiers are a good match for the GSource implementation, too, because the Win32 port of glib allows to place their HANDLEs in a GPollFD. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2012-10-30aio: prepare for introducing GSource-based dispatchPaolo Bonzini
This adds a GPollFD to each AioHandler. It will then be possible to attach these GPollFDs to a GSource, and from there to the main loop. aio_wait examines the GPollFDs and avoids calling select() if any is set (similar to what it does if bottom halves are available). Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2012-10-30aio: add non-blocking variant of aio_waitPaolo Bonzini
This will be used when polling the GSource attached to an AioContext. Reviewed-by: Anthony Liguori <aliguori@us.ibm.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2012-10-30aio: test node->deleted before calling io_flushPaolo Bonzini
Otherwise, there could be a case where io_flush accesses freed memory because it should not have been called. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2012-10-30aio: add I/O handlers to the AioContext interfacePaolo Bonzini
With this patch, I/O handlers (including event notifier handlers) can be attached to a single AioContext. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2012-10-30aio: introduce AioContext, move bottom halves therePaolo Bonzini
Start introducing AioContext, which will let us remove globals from aio.c/async.c, and introduce multiple I/O threads. The bottom half functions now take an additional AioContext argument. A bottom half is created with a specific AioContext that remains the same throughout the lifetime. qemu_bh_new is just a wrapper that uses a global context. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2012-10-30aio: provide platform-independent APIPaolo Bonzini
This adds to aio.c a platform-independent API based on EventNotifiers, that can be used by both POSIX and Win32. Reviewed-by: Anthony Liguori <aliguori@us.ibm.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2012-10-30aio: change qemu_aio_set_fd_handler to return voidPaolo Bonzini
Reviewed-by: Anthony Liguori <aliguori@us.ibm.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2012-10-30vl: init main loop earlierPaolo Bonzini
Otherwise, chardevs will not be able to create a bottom half as soon as that will require an AioContext. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2012-10-30event_notifier: enable it to use pipesPaolo Bonzini
This takes the eventfd emulation code from the main loop. When the EventNotifier is used for the main loop too, we need this compatibility code. Without CONFIG_EVENTFD, event_notifier_get_fd is only usable for the "read" side of the notifier, for example to set a select() handler. The return value of event_notifier_set changes to the cleaner 0/-errno. No caller is actually checking the return value.

2012-10-30build: opts-visitor is not really part of QAPIPaolo Bonzini
It is only used by QEMU itself, do not build it into the tests. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2012-10-30sockets: use weak aliases instead of qemu-tool.cPaolo Bonzini
qemu-tool.c has its own (largeish) set of dependencies. Weak aliases can be placed directly where people use them, and do not contribute to increasing the dependencies of generic utility files. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2012-10-30compiler: use weak aliases to provide default definitionsPaolo Bonzini
This is simpler and more portable. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

This removes the dependency of cutils.c on iov.c, and lets us remove iov.o from several builds. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
