Revision 6983d1657dc1784288eb299f5f001fb56af705d8 authored by Wei Wang on 05 April 2024, 03:40:56 UTC, committed by Michael Tokarev on 09 April 2024, 17:18:26 UTC
Before loading the guest states, ensure that the preempt channel has been
ready to use, as some of the states (e.g. via virtio_load) might trigger
page faults that will be handled through the preempt channel. So yield to
the main thread in the case that the channel create event hasn't been
dispatched.
