The next part is CoMutex thread-safety, which is relatively small (10 patches). Paolo Paolo Bonzini (18): block: move AioContext, QEMUTimer, main-loop to libqemuutil aio: introduce aio_co_schedule and aio_co_wake block-backend: allow blk_prw from coroutine context test-thread-pool: use generic AioContext infrastructure io: add methods to set I/O handlers on AioContext io: make qio_channel_yield aware of AioContexts nbd: convert to use qio_channel_yield coroutine-lock: reschedule coroutine on the AioContext it was running on blkdebug: reschedule coroutine on the AioContext it is running on qed: introduce qed_aio_start_io and qed_aio_next_io_cb aio: push aio_context_acquire/release down to dispatching block: explicitly acquire aiocontext in timers that need it block: explicitly acquire aiocontext in callbacks that need it block: explicitly acquire aiocontext in bottom halves that need it block: explicitly acquire aiocontext in aio callbacks that need it aio-posix: partially inline aio_dispatch into aio_poll async: remove unnecessary inc/dec pairs block: document fields protected by AioContext lock Makefile.objs | 4 - block/blkdebug.c | 9 +- block/blkreplay.c | 2 +- block/block-backend.c | 13 ++- block/curl.c | 44 ++++++-- block/gluster.c | 9 +- block/io.c | 38 ++----- block/iscsi.c | 15 ++- block/linux-aio.c | 10 +- block/mirror.c | 12 +- block/nbd-client.c | 117 +++++++++----------- block/nbd-client.h | 2 +- block/nfs.c | 9 +- block/qed-cluster.c | 2 + block/qed-table.c | 12 +- block/qed.c | 58 +++++++--- block/qed.h | 3 + block/sheepdog.c | 29 ++--- block/ssh.c | 29 ++--- block/throttle-groups.c | 2 + block/win32-aio.c | 9 +- dma-helpers.c | 2 + hw/block/virtio-blk.c | 19 +++- hw/scsi/scsi-bus.c | 2 + hw/scsi/scsi-disk.c | 15 +++ hw/scsi/scsi-generic.c | 20 +++- hw/scsi/virtio-scsi.c | 6 + include/block/aio.h | 38 ++++++- include/block/block_int.h | 64 ++++++----- include/io/channel.h | 72 +++++++++++- include/qemu/coroutine_int.h | 11 +- include/sysemu/block-backend.h | 14 ++- io/channel-command.c | 13 +++ io/channel-file.c | 11 ++ io/channel-socket.c | 16 ++- io/channel-tls.c | 12 ++ io/channel-watch.c | 6 + io/channel.c | 97 ++++++++++++---- nbd/client.c | 2 +- nbd/common.c | 9 +- nbd/server.c | 94 +++++----------- stubs/Makefile.objs | 1 + stubs/linux-aio.c | 32 ++++++ stubs/set-fd-handler.c | 11 -- tests/Makefile.include | 19 ++-- tests/iothread.c | 91 +++++++++++++++ tests/iothread.h | 25 +++++ tests/test-aio-multithread.c | 213 ++++++++++++++++++++++++++++++++++++ tests/test-thread-pool.c | 12 +- trace-events | 4 + util/Makefile.objs | 6 +- aio-posix.c => util/aio-posix.c | 60 +++------- aio-win32.c => util/aio-win32.c | 30 ++--- util/aiocb.c | 55 ++++++++++ async.c => util/async.c | 84 ++++++++++++-- iohandler.c => util/iohandler.c | 0 main-loop.c => util/main-loop.c | 0 util/qemu-coroutine-lock.c | 5 +- util/qemu-coroutine-sleep.c | 2 +- util/qemu-coroutine.c | 8 ++ qemu-timer.c => util/qemu-timer.c | 0 thread-pool.c => util/thread-pool.c | 6 +- util/trace-events | 1 - 63 files changed, 1161 insertions(+), 455 deletions(-) create mode 100644 stubs/linux-aio.c create mode 100644 tests/iothread.c create mode 100644 tests/iothread.h create mode 100644 tests/test-aio-multithread.c rename aio-posix.c => util/aio-posix.c (94%) rename aio-win32.c => util/aio-win32.c (95%) create mode 100644 util/aiocb.c rename async.c => util/async.c (82%) rename iohandler.c => util/iohandler.c (100%) rename main-loop.c => util/main-loop.c (100%) rename qemu-timer.c => util/qemu-timer.c (100%) rename thread-pool.c => util/thread-pool.c (98%) -- 2.9.3
