[Qemu-devel] [PATCH 2/2] spice-char: notify the server when chardev is writable |
Date: |
Tue, 5 May 2015 16:58:56 +0200 |
The spice server is polling on write, unless
SPICE_CHAR_DEVICE_NOTIFY_WRITABLE flag is set. In this case, qemu must
call spice_server_char_device_wakeup() when the frontend is writable.
