| * ALSA: Add snd_ctl_replace() to dynamically replace a controlDimitris Papastamos2011-03-22
| | | | | | | | | | | | | | | | | | | | | | | | 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.

* ALSA: Add snd_ctl_activate_id()Takashi Iwai2011-03-11

* ALSA: core, oxygen, virtuoso: add an enum control info helperClemens Ladisch2011-01-10
| | | | | | | | Introduce the helper function snd_ctl_enum_info() to fill out the elem_info fields for an enumerated control. Signed-off-by: Clemens Ladisch <clemens@ladisch.de> Signed-off-by: Takashi Iwai <tiwai@suse.de>
* control: use reference-counted pidClemens Ladisch2009-11-06
| | | | | | | | | | 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 fieldClemens Ladisch2009-11-06
| | | | | | | | 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 <clemens@ladisch.de> Signed-off-by: Takashi Iwai <tiwai@suse.de>

* ALSA: add snd_ctl_add_slave_uncached()Takashi Iwai2009-03-09
| | | | | | | | | | | | | | | 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.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
