docs: create config/, devel/ and spin/ subdirectories

2017-06-07T16:22:03+00:00

Developer documentation should be its own manual. As a start, move all developer-oriented files to a separate directory. Also move non-text files to their own directories: docs/config/ for QEMU -readconfig input, and docs/spin/ for formal models to be used with the SPIN model checker. Reviewed-by: Daniel P.

iothread: release AioContext around aio_poll

2016-10-28T13:50:18+00:00

This is the first step towards having fine-grained critical sections in dataplane threads, which will resolve lock ordering problems between address_space_* functions (which need the BQL when doing MMIO, even after we complete RCU-based dispatch) and the AioContext. Because AioContext does not use contention callbacks anymore, the unit test has to be changed. Previously applied as a0710f7995f914e3044e5899bd8ff6c43c62f916 and then reverted.

docs/multiple-iothreads.txt: add documentation on IOThread programming

2014-08-15T13:07:13+00:00

This document explains how IOThreads and the main loop are related, especially how to write code that can run in an IOThread. Currently only virtio-blk-data-plane uses these techniques. The next obvious target is virtio-scsi; there has also been work on virtio-net. Signed-off-by: Stefan Hajnoczi Reviewed-by: Eric Blake
