ALSA: hda - Cache the jack-detection value Introduce a table containing the pins and their jack-detection states for avoiding the unnecessary verbs to check the pin status at each time. When the unsol event is enabled via snd_hda_jack_detect_enable(), it automatically adds the given NID to the table. Then the driver supposes that the codec driver will set the dirty flag appropariately when an unsolicited event is invoked for that pin. The behavior for reading other pins that aren't registered in the table doesn't change. Only the pins assigned to the table are cached, so far. In near futre, this table can be extended to use the central place for the unsolicited events of all pins, etc, and eventually include the jack-detect kcontrols that replace the current input-jack stuff.

ALSA: HDA: Create phantom jacks for fixed inputs and outputs PulseAudio sometimes have difficulties knowing that there is a "Speaker" or "Internal Mic", if they have no individual volume controls or selectors. As a result, only e g "Headphone" might be created for a laptop, but no "Speaker". To help out, create phantom jacks (that are always present, at least for now) for "Speaker", "Internal Mic" etc, in case we detect them. The naming convention is e g "Speaker Phantom Jack". In order not to pollute the /dev/input namespace with even more devices, these are added to the kcontrols only, not the input devices.

ALSA: hda - Add snd_hda_jack_detect_state() helper function snd_hda_jack_detect() function returns a boolean value for a jack plugged in or not, but it also returns always true when the corresponding pin is phantom (i.e. fixed). This is OK in most cases, but it makes the generic parser misbehaving about the auto-mute or auto-mic switching, e.g. when one of headphone pins is a fixed. Namely, the driver decides whether to mute the speaker or not, just depending on the headphone plug state: if one of the headphone jacks is seen as active, then the speaker is muted. Thus this will result always in the muted speaker output. So, the problem is the function returns a boolean, after all, although we need to think of "phantom" jack. Now a new function, snd_hda_jack_detect_state() is introduced to return these tristates. The generic parser uses this function for checking the headphone or mic jack states. Meanwhile, the behavior of snd_hda_jack_detect() is kept as is, for keeping compatibility in other driver codes.

The control elements are created with iface=CARD, so that they won't appear in the mixer apps. So far, only the pins that enabled the jack-detection are registered. For covering all pins, the transition of the common unsol-tag handling would be needed. Stay tuned. Signed-off-by: Takashi Iwai <tiwai@suse.de>

ALSA: hda - make a generic unsol event handler Moving towards less duplication of code between codecs - this patch takes some of the common code of unsol event handling and makes it generic.

void snd_hda_jack_unsol_event(struct hda_codec *codec, unsigned int res);
ALSA: hda - Create jack-detection kcontrols Create kcontrols for pin jack-detections, which work similarly like jack-input layer. Each control will notify when the jack is plugged or unplugged, and also user can read the value at any time via the normal control API. The control elements are created with iface=CARD, so that they won't appear in the mixer apps. So far, only the pins that enabled the jack-detection are registered.

ALSA: hda - Implement a poll loop for jacks as a module parameter Now that we have a generic unsol mechanism, we can implement a generic poll loop, which can be used for debugging, or if a codec's unsol mechanism is broken.

void snd_hda_jack_poll_all(struct hda_codec *codec);
ALSA: hda - Cache the jack-detection value Introduce a table containing the pins and their jack-detection states for avoiding the unnecessary verbs to check the pin status at each time. When the unsol event is enabled via snd_hda_jack_detect_enable(), it automatically adds the given NID to the table. Then the driver supposes that the codec driver will set the dirty flag appropariately when an unsolicited event is invoked for that pin. The behavior for reading other pins that aren't registered in the table doesn't change. Only the pins assigned to the table are cached, so far. In near futre, this table can be extended to use the central place for the unsolicited events of all pins, etc, and eventually include the jack-detect kcontrols that replace the current input-jack stuff.
