2017-12-21cpu: refactor cpu_address_space_init()Peter Xu
Normally we create an address space for that CPU and pass that address space into the function. Let's just do it inside to unify address space creations. It'll simplify my next patch to rename those address spaces.

2017-12-21sockets: remove obsolete code that updated listen addressDaniel P. Berrange
When listening on unix/tcp sockets there was optional code that would update the original SocketAddress struct with the info about the actual address that was listened on. Since the conversion of everything to QIOChannelSocket, no remaining caller made use of this feature. It has been replaced with the ability to query the listen address after the fact using the function qio_channel_socket_get_local_address. This is a better model when the input address can result in listening on multiple distinct sockets. Signed-off-by: Daniel P.

IOThread: while (!atomic_read(&iothread->stopping)) -> stopping=false 2. Main loop: iothread->stopping = true; aio_notify(iothread->ctx); 3. IOThread: aio_poll(iothread->ctx, true); -> hang The bug is explained by the AioContext->notify_me doc comments: "If this field is 0, everything (file descriptors, bottom halves, timers) will be re-evaluated before the next blocking poll(), thus the event_notifier_set call can be skipped." The problem is that "everything" does not include checking iothread->stopping. This means iothread_run() will block in aio_poll() if aio_notify() was called just before aio_poll(). This patch fixes the hang by replacing aio_notify() with aio_bh_schedule_oneshot(). This makes aio_poll() or g_main_loop_run() to return. Implementing this properly required a new bool running flag. The new flag prevents races that are tricky if we try to use iothread->stopping. Now iothread->stopping is purely for iothread_stop() and iothread->running is purely for the iothread_run() thread.

2017-12-19hw/block: Fix the return typeMao Zhongyi
When the function no success value to transmit, it usually make the function return void. It has turned out not to be a success, because it means that the extra local_err variable and error_propagate() will be needed. It leads to cumbersome code, therefore, transmit success/ failure in the return value is worth. So fix the return type of blkconf_apply_backend_options(), blkconf_geometry() and virtio_blk_data_plane_create() to avoid it.

2017-12-19coroutine: simplify co_aio_sleep_ns() prototypeStefan Hajnoczi
The AioContext pointer argument to co_aio_sleep_ns() is only used for the sleep timer. It does not affect where the caller coroutine is resumed. Due to changes to coroutine and AIO APIs it is now possible to drop the AioContext pointer argument. This is safe to do since no caller has specific requirements for which AioContext the timer must run in. This patch drops the AioContext pointer argument and renames the function to simplify the API.

2017-12-15sparc: Make sure we mmap at SHMLBA alignmentPeter Maydell
SPARC Linux has an oddity that it insists that mmap() of MAP_FIXED memory must be at an alignment defined by SHMLBA, which is more aligned than the page size (typically, SHMLBA alignment is to 16K, and pages are 8K). This is a relic of ancient hardware that had cache aliasing constraints, but even on modern hardware the kernel still insists on the alignment. To ensure that we get mmap() alignment sufficient to make the kernel happy, change QEMU_VMALLOC_ALIGN, qemu_fd_getpagesize() and qemu_mempath_getpagesize() to use the maximum of getpagesize() and SHMLBA. In particular, this allows 'make check' to pass on Sparc: we were previously failing the ivshmem tests.

into staging ppc patch queue 2017-12-15 First pull request for qemu-2.12. This has quite a bit of stuff accumulated while 2.11 was finalizing.

2017-12-14tpm: tpm_emulator: get and set buffer size of deviceStefan Berger
Convert the tpm_emulator backend to get the current buffer size of the external device and set it to the buffer size that the frontend (TIS) requests. Signed-off-by: Stefan Berger <stefanb@linux.vnet.ibm.com> Reviewed-by: Marc-André Lureau <marcandre.lureau@redhat.com>
2017-12-14tpm: Move getting TPM buffer size to backendsStefan Berger
Rather than setting the size of the TPM buffer in the front-end, query the backend for the size of the buffer. In this patch we just move the hard-coded buffer size of 4096 to the backends.

2017-12-14tpm-be: update optional function pointersMarc-André Lureau
QEMU code doesn't generally have assert() for mandatory callbacks/function pointers, probably because the crash is pretty obvious. Document the methods instead of going into the code. Make get_tpm_options() mandatory to implement (since all backend implementation have it).
