* coroutine: move into libqemuutil.a libraryDaniel P. Berrange2015-10-201-41/+0Star
| | | | | | | | | | | | | | | | | The coroutine files are currently referenced by the block-obj-y variable. The coroutine functionality though is already used by more than just the block code. eg migration code uses coroutine yield. In the future the I/O channel code will also use the coroutine yield functionality. Since the coroutine code is nicely self-contained it can be easily built as part of the libqemuutil.a library, making it widely available. The headers are also moved into include/qemu, instead of the include/block directory, since they are now part of the util codebase, and the impl was never in the block/ directory either.

* coroutine: Drop co_sleep_nsFam Zheng2014-08-291-12/+0Star
| | | | | | | | | | block_job_sleep_ns is the only user. Since we are moving towards AioContext aware code, it's better to use the explicit version and drop the old one.

* coroutine: add co_aio_sleep_ns() to allow sleep in block driversMORITA Kazutaka2013-10-301-0/+14
| | | | | | | | | | This helper function behaves similarly to co_sleep_ns(), but the sleeping coroutine will be resumed when using qemu_aio_wait().
