Subject: spice-char: notify the server when chardev is writable
X-Git-Tag: v2.4.0-rc0~114^2~2
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=e95e203c085b7731746e39c9b9f8bd2f6eaa0cd6;p=users%2Fdwmw2%2Fqemu.git

spice-char: notify the server when chardev is writable

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.
