[Qemu-devel] [PATCH v2 0/4] chardev: support non-default gcontext

[Peter Xu <peterx@redhat.com>]

The old chardev may not fully support non-default GMainContext.  One
direct clue is that when we call io_add_watch_poll() sometimes we are
still passing in the NULL context pointer.

IIUC we are fine during setup since the context will be passed
correctly during setup via chr_update_read_handler().  However it
won't survive if chardev reconnected due to some reason.

This series tries to solve above problem by caching the gcontext
pointer in Chardev itself.

This will be required for the monitor OOB (out-of-band) support, since
in that series monitor backends may be run in non-default contexts.

Please review.  Thanks.

Peter Xu (4):
  chardev: new qemu_chr_be_update_read_handlers()
  chardev: add Chardev.gcontext field
  chardev: use per-dev context for io_add_watch_poll
  chardev: remove context in chr_update_read_handler
