* 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.

* ALSA: make snd_ctl_elem_read() and snd_ctl_elem_write() staticTakashi Iwai2008-06-13
| | | | | | | | snd_ctl_elem_read() and snd_ctl_elem_write() are no longer used by any other drivers. Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Jaroslav Kysela <perex@perex.cz>
* [ALSA] Move vmaster code to sound coreTakashi Iwai2008-04-24
| | | | | | | Move the codes for virtual master controls to sound core part so that not only hda-intel drivers can use it. Signed-off-by: Takashi Iwai <tiwai@suse.de>

* [ALSA] Add helper functions for frequently used callbacksTakashi Iwai2007-10-16
| | | | | | | | Added helper functions for frequenty used callbacks: snd_ctl_boolean_mono_info() and snd_ctl_boolean_stereo_info() Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Jaroslav Kysela <perex@suse.cz>
* [ALSA] Add even more 'const' to everything related to TLVTakashi Iwai2007-02-09
| | | | | | | | Mark TLV data as 'const' Signed-of-by: Philipp Matthias Hahn <pmhahn@pmhahn.de> Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Jaroslav Kysela <perex@suse.cz>
* [ALSA] make sound/core/control.c:snd_ctl_new() staticAdrian Bunk2007-02-09
| | | | | | | | | Now that everyone uses snd_ctl_new1() and noone is using snd_ctl_new() anymore, we can make it static. Signed-off-by: Adrian Bunk <bunk@stusta.de> Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Jaroslav Kysela <perex@suse.cz>
* [ALSA] Remove unused tlv_rw field from struct snd_kcontrolTakashi Iwai2006-09-23
| | | | | | | | Remove unused tlv_rw field from struct snd_kcontrol. The callback is set in tlv.c field, instead. Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Jaroslav Kysela <perex@suse.cz>
* [ALSA] Control API - more robust TLV implementationJaroslav Kysela2006-09-23
| | | | | | | | | | - added callback option - added READ/WRITE/COMMAND flags to access member - added WRITE/COMMAND ioctls - added SNDRV_CTL_EVENT_MASK_TLV for TLV change notifications - added TLV support to ELEM_ADD ioctl Signed-off-by: Jaroslav Kysela <perex@suse.cz>
* [ALSA] Control API - TLV implementation for additional information like dB scaleJaroslav Kysela2006-09-23
| | | | | | | | This patch implements a TLV mechanism to transfer an additional information like dB scale to the user space. The types might be extended in future. Acked-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Jaroslav Kysela <perex@suse.cz>

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!
