ALSA: Add snd_ctl_replace() to dynamically replace a control

2011-03-22T12:22:39Z

Add a function to dynamically replace a given control. If the control does not already exist, a third parameter is used to determine whether to actually add that control. This is useful in cases where downloadable firmware at runtime can add or replace existing controls. A separate patch needs to be made to allow ALSA Mixer to render the replaced controls on the fly.

Added a new API function snd_ctl_activate_id() for activate / inactivate the control element dynamically. Signed-off-by: Takashi Iwai Signed-off-by: Mark Brown

ALSA: core, oxygen, virtuoso: add an enum control info helper

2011-01-10T15:46:53Z

Introduce the helper function snd_ctl_enum_info() to fill out the elem_info fields for an enumerated control. Signed-off-by: Clemens Ladisch Signed-off-by: Takashi Iwai

control: use reference-counted pid

2009-11-06T13:32:06Z

Instead of storing the PID number, take a reference to the task's pid structure. This protects against duplicates due to PID overflows, and using pid_vnr() ensures that the PID returned by snd_ctl_elem_info() is correct as seen from the current namespace.

control: remove snd_konctrol_volatile::owner_pid field

2009-11-06T13:32:03Z

We do not need to save the ID of the process that locked a control because that information is already available in the owner's file data. Signed-off-by: Clemens Ladisch Signed-off-by: Takashi Iwai

ALSA: add snd_ctl_add_slave_uncached()

2009-03-09T13:56:19Z

Added snd_ctl_add_slave_uncached() function to add a slave element with volatile controls. The values of normal slave elements are supposed to be cachable, i.e. they are changed only via the put callbacks. OTOH, when a slave element is volatile and its values may be changed by other reason (e.g. hardware status change), the values will get inconsistent. The new function allows the slave elements with volatile changes. When the slave is tied with this call, the native get callback is issued at each time so that the values are always updated.

ALSA: make snd_ctl_elem_read() and snd_ctl_elem_write() static

2008-06-13T14:48:49Z

snd_ctl_elem_read() and snd_ctl_elem_write() are no longer used by any other drivers. Signed-off-by: Takashi Iwai Signed-off-by: Jaroslav Kysela
