* mixer: remove alloca() from set_enum_item_ops()Takashi Sakamoto2016-07-151-5/+4
| | | | | | | | | | | | Both of alloca() and automatic variables keep storages on stack, while the former generates more instructions than the latter. It's better to use the latter if the size of storage is computable at pre-compile or compile time; i.e. just for structures. This commit obsolete usages of alloca() with automatic variables.

* mixer: include library local header to find layout of structuresTakashi Sakamoto2016-07-151-1/+1
| | | | | | | | | | | | | | Inner this library, implementation of each features can find actual layout of structures by including local header. Although, mixer feature is written without the header and as the same way for applications. This brings some inefficiencies such as usage of alloca() to keep memory objects for the structures. This commit includes the header for further improvements in mixer feature. Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp> Signed-off-by: Takashi Iwai <tiwai@suse.de>

* Mark static tables as constant when possible.Diego E. 'Flameeyes' Pettenò2008-11-211-5/+5
| | | | | | | This makes it possible to write them to .data.rel.ro or to .rodata if there is no relocation involved (arrays of character arrays). Signed-off-by: Diego E. 'Flameeyes' Pettenò <flameeyes@gmail.com>

* Fix volume/switch updates for global/simple mixer elementsTakashi Iwai2008-11-101-3/+19
| | | | | | | Fixed a long-standing bug that the values of global or simple mixer elements aren't updated when dir = SM_CAPT is given. Signed-off-by: Takashi Iwai <tiwai@suse.de>

* simple mixer: fix calculation of control rangeClemens Ladisch2007-11-121-6/+9
| | | | | | When calculating the value range of a control, the variables cannot be initialized with zero because this would prevent the minimum from having a value above zero or the maximum from having a value below zero.
* Remove assert from header filesTakashi Iwai2007-10-251-0/+1
| | | | | | | | Putting assert in the public macros isn't good idea at all. Let's get rid of them. Also, clean up snd*_alloca() functions to use a helper macro instead of copy and paste.
* Export dB conversion helper functionsTakashi Iwai2007-10-241-264/+13
| | | | | | | Export helper functions to convert dB level and range. snd_tlv_*dB*() are to convert dB level or range directly from TLV data. snd_ctl_*dB*() are to get dB level or range from a control element.

* Handle "Input Source" as a capture elementTakashi Iwai2007-08-291-3/+31
| | | | | | | Some drivers use "Input Source" as the capture source mixer element because mixer abstraction layer can't handle multiple "Capture Source" elements. This patch adds a hack to handle Input Source as a capture route, and let mixer apps know that it's a capture stuff, at least.

* add snd_device_name_hint() function and initial implementationJaroslav Kysela2006-10-111-0/+4
| | | | | | | | | | - add snd_device_name_hint() and snd_device_name_free_hint() functions - add snd_ctl_iface_conf_name() functions - do not accept parameters for the plugin definition without @args section - add defaults.pcm.dmix.card/device and dsnoop.card/device definitions - add hints for HDA-Intel.conf, pcm/dmix.conf, pcm/dsnoop.conf and alsa.conf - add test/namehint test utility - doxygen related cleanups
* simple mixer - fix error recovery path for volume / switch writeJaroslav Kysela2006-10-011-1/+11
| | | | | | If volume or switch write fails, the internal contents for element is changed, but it is wrong. Reread the whole simple element in this case to get correct values.
* Fix wrong scales in linear volume calculationTakashi Iwai2006-09-071-5/+5
| | | | | Fixed wrong scales of dB values (TLV is 0.01dB unit) in the linear volume calculation.
* Add support of dB range compound TLVTakashi Iwai2006-09-061-50/+144
| | | | | Added the support of dB range compound TLV type in the simple mixer layer. All get_dB, get_dB_range and set_dB ops are supported.
* Add handling of linear volume in simple mixerTakashi Iwai2006-08-281-4/+64
| | | | Added the handling of linear volume TLV in the simple mixer layer.
* Add set_dB ops to simple mixerTakashi Iwai2006-08-251-21/+63
| | | | Added the set_dB ops to simple mixer.
* Add dB_range ops for simple mixerTakashi Iwai2006-08-251-22/+58
| | | | Added the dB_range ops for simple mixer.
