Subject: [PATCH 0/6] coroutine: new sleep/wake API
Date: Mon, 3 May 2021 13:25:44 +0200 [thread overview]
Message-ID: <20210503112550.478521-1-pbonzini@redhat.com> (raw)
This is a revamp of the qemu_co_sleep* API that makes it easier to
extend the API: the state that is needed to wake up a coroutine is now
part of the public API instead of hidden behind a pointer-to-pointer;
the API is made more extensible by pushing the rest of QemuCoSleepState
into local variables.
In the future, this will be extended to introduce a prepare/sleep/cancel
API similar to Linux's prepare_to_wait/schedule/finish_wait functions.
For now, this is just a nice refactoring.
Paolo Bonzini (6):
coroutine-sleep: use a stack-allocated timer
coroutine-sleep: disallow NULL QemuCoSleepState** argument
coroutine-sleep: allow qemu_co_sleep_wake(NULL)
coroutine-sleep: move timer out of QemuCoSleepState
coroutine-sleep: replace QemuCoSleepState pointer with struct in the
API
coroutine-sleep: introduce qemu_co_sleep
