2021-03-07ALSA: virtio: handling control messagesAnton Yakovlev
The control queue can be used by different parts of the driver to send commands to the device. Control messages can be either synchronous or asynchronous. The lifetime of a message is controlled by a reference count. Introduce a module parameter to set the message completion timeout: msg_timeout_ms [=1000] Signed-off-by: Anton Yakovlev <anton.yakovlev@opensynergy.com> Link: https://lore.kernel.org/r/20210302164709.3142702-4-anton.yakovlev@opensynergy.com Signed-off-by: Takashi Iwai <tiwai@suse.de>
