[Qemu-devel] [PATCHv2] [RFC 0/7] aio / timers: Add AioContext timers and use ppoll |
Date: |

This patch series adds support for timers attached to an AioContext clock
which get called within aio_poll.
In doing so it removes alarm timers and moves to use ppoll where possible.
This patch set 'sort of' passes make check (see below for caveat)
including a new test harness for the aio timers, but has not been
tested much beyond that. In particular, the win32 changes have not
even been compile tested.
Caveat: make check fails one test only with:
ERROR:tests/test-aio.c:346:test_wait_event_notifier_noflush: assertion failed:
(aio_poll(ctx, false))
As gar as I can tell, this check is incorrect, in that it checking aio_poll
makes progress when in fact it should not make progress. I fixed an issue
where aio_poll was (as far as I can tell) wrongly returning true on
a timeout, and that generated this error.
Alex Bligh (7):
aio / timers: Remove alarm timers
aio / timers: qemu-timer.c utility functions and add list of clocks
aio / timers: add ppoll support with qemu_g_poll_ns
aio / timers: Make qemu_run_timers and qemu_run_all_timers return
progress
aio / timers: Add a clock to AioContext
aio / timers: Switch to ppoll, run AioContext timers in
aio_poll/aio_dispatch
aio / timers: Add test harness for AioContext timers
