[Qemu-devel] [PATCH v4 00/18] aio_context_acquire/release pushdown, part


From: Paolo Bonzini
Subject: [Qemu-devel] [PATCH v4 00/18] aio_context_acquire/release pushdown, part 2
Date: Mon, 13 Feb 2017 11:08:48 +0100

Same as v3 except for tests/Makefile.include rebase in patch 1.

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
