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 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. 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 - Remove ignore_misc_bit The purpose of this flag is unclear. If the problem is that some machines have broken misc/NO_PRESENCE bits, they should be fixed by pin fixups. In addition, this causes jack detection functionality to be flawed on the M31EI, where there are two jacks without jack detection (which is properly marked as NO_PRESENCE), but due to ignore_misc_bit, these jacks are instead being reported as being present but always unplugged.

ALSA: hda - Add DP-MST jack support This patch adds DP-MST jack support which will be used on NVIDIA platforms. Today, DP-MST audio is supported only if the codec has acomp support. This patch makes it possible to add DP-MST support for non-acomp codecs. For the codecs supporting DP-MST audio, each pin can contain several device entries. Each device entry is a virtual pin, described by pin_nid and dev_id in struct hdmi_spec_per_pin. For monitor hotplug event handling, non-acomp codecs enable and register jack-detection for every hdmi_spec_per_pin. This patch updates every relevant function in hda_jack.h and its implementation in hda_jack.c, to consider dev_id along with pin_nid. Changes to the HD Audio specification to support DP-MST audio are described in the Intel Document Change Notification (DCN) number HDA040-A. From HDA040-A, "For the case of multi stream capable Digital Display Pin Widget, [the Get Pin Sense verb] can be used to read a specific Device Entry state as reported in Get Device List Entry verb." This patch updates the read_pin_sense() function to take the dev_id as an argument and pass it as a parameter to the Get Pin Sense verb. Bits 15 through 20 from the Unsolicited Response for intrinsic events contain the index of the Device Entry that generated the event. This patch updates the Unsolicited Response event handlers to extract the device entry index from the response and pass it to snd_hda_jack_tbl_get_from_tag(). This patch updates snd_hda_jack_tbl_new() to take a dev_id argument and store it in the jack structure, and to make sure not to generate a different tag when called more than once for the same nid.

ALSA: hda - Add DP-MST jack support This patch adds DP-MST jack support which will be used on NVIDIA platforms. Today, DP-MST audio is supported only if the codec has acomp support. This patch makes it possible to add DP-MST support for non-acomp codecs. For the codecs supporting DP-MST audio, each pin can contain several device entries. Each device entry is a virtual pin, described by pin_nid and dev_id in struct hdmi_spec_per_pin. For monitor hotplug event handling, non-acomp codecs enable and register jack-detection for every hdmi_spec_per_pin. This patch updates every relevant function in hda_jack.h and its implementation in hda_jack.c, to consider dev_id along with pin_nid. Changes to the HD Audio specification to support DP-MST audio are described in the Intel Document Change Notification (DCN) number HDA040-A. From HDA040-A, "For the case of multi stream capable Digital Display Pin Widget, [the Get Pin Sense verb] can be used to read a specific Device Entry state as reported in Get Device List Entry verb." This patch updates the read_pin_sense() function to take the dev_id as an argument and pass it as a parameter to the Get Pin Sense verb. Bits 15 through 20 from the Unsolicited Response for intrinsic events contain the index of the Device Entry that generated the event. This patch updates the Unsolicited Response event handlers to extract the device entry index from the response and pass it to snd_hda_jack_tbl_get_from_tag(). This patch updates snd_hda_jack_tbl_new() to take a dev_id argument and store it in the jack structure, and to make sure not to generate a different tag when called more than once for the same nid.

ALSA: hda - Allow multiple callbacks for jack So far, hda_jack infrastructure allows only one callback per jack, and this makes things slightly complicated when a driver wants to assign multiple tasks to a jack, e.g. the standard auto-mute with a power up/down sequence. This can be simplified if the hda_jack accepts multiple callbacks. This patch is such an extension: the callback-specific part (the function and private_data) is split to another struct from hda_jack_tbl, and multiple such objects can be assigned to a single hda_jack_tbl entry. The new struct hda_jack_callback is passed to each callback function now, thus the patch became bigger than expected. But these changes are mostly trivial. Signed-off-by: Takashi Iwai <tiwai@suse.de>

ALSA: hda - Allow jack state to depend on another jack Introduce the concept of a "gated" jack. The gated jack's pin sense is only valid when the "gating" jack is plugged. This requires checking the gating jack when the gated jack changes and re-checking the gated jack when the gating jack is plugged/unplugged. This allows handling of devices where the mic jack detect floats when the headphone jack is unplugged.

ALSA: hda - Add DP-MST jack support This patch adds DP-MST jack support which will be used on NVIDIA platforms. Today, DP-MST audio is supported only if the codec has acomp support. This patch makes it possible to add DP-MST support for non-acomp codecs. For the codecs supporting DP-MST audio, each pin can contain several device entries. Each device entry is a virtual pin, described by pin_nid and dev_id in struct hdmi_spec_per_pin. For monitor hotplug event handling, non-acomp codecs enable and register jack-detection for every hdmi_spec_per_pin. This patch updates every relevant function in hda_jack.h and its implementation in hda_jack.c, to consider dev_id along with pin_nid. Changes to the HD Audio specification to support DP-MST audio are described in the Intel Document Change Notification (DCN) number HDA040-A. From HDA040-A, "For the case of multi stream capable Digital Display Pin Widget, [the Get Pin Sense verb] can be used to read a specific Device Entry state as reported in Get Device List Entry verb." This patch updates the read_pin_sense() function to take the dev_id as an argument and pass it as a parameter to the Get Pin Sense verb.

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.

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 - 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.

ALSA: hda - Allow multiple callbacks for jack So far, hda_jack infrastructure allows only one callback per jack, and this makes things slightly complicated when a driver wants to assign multiple tasks to a jack, e.g. the standard auto-mute with a power up/down sequence. This can be simplified if the hda_jack accepts multiple callbacks. This patch is such an extension: the callback-specific part (the function and private_data) is split to another struct from hda_jack_tbl, and multiple such objects can be assigned to a single hda_jack_tbl entry. The new struct hda_jack_callback is passed to each callback function now, thus the patch became bigger than expected. But these changes are mostly trivial. Signed-off-by: Takashi Iwai <tiwai@suse.de>

ALSA: hda - Allow multiple callbacks for jack So far, hda_jack infrastructure allows only one callback per jack, and this makes things slightly complicated when a driver wants to assign multiple tasks to a jack, e.g. the standard auto-mute with a power up/down sequence. This can be simplified if the hda_jack accepts multiple callbacks. This patch is such an extension: the callback-specific part (the function and private_data) is split to another struct from hda_jack_tbl, and multiple such objects can be assigned to a single hda_jack_tbl entry. The new struct hda_jack_callback is passed to each callback function now, thus the patch became bigger than expected. But these changes are mostly trivial. Signed-off-by: Takashi Iwai <tiwai@suse.de>

ALSA: hda - Add DP-MST jack support This patch adds DP-MST jack support which will be used on NVIDIA platforms. Today, DP-MST audio is supported only if the codec has acomp support. This patch makes it possible to add DP-MST support for non-acomp codecs. For the codecs supporting DP-MST audio, each pin can contain several device entries. Each device entry is a virtual pin, described by pin_nid and dev_id in struct hdmi_spec_per_pin. For monitor hotplug event handling, non-acomp codecs enable and register jack-detection for every hdmi_spec_per_pin. This patch updates every relevant function in hda_jack.h and its implementation in hda_jack.c, to consider dev_id along with pin_nid. Changes to the HD Audio specification to support DP-MST audio are described in the Intel Document Change Notification (DCN) number HDA040-A. From HDA040-A, "For the case of multi stream capable Digital Display Pin Widget, [the Get Pin Sense verb] can be used to read a specific Device Entry state as reported in Get Device List Entry verb." This patch updates the read_pin_sense() function to take the dev_id as an argument and pass it as a parameter to the Get Pin Sense verb. Bits 15 through 20 from the Unsolicited Response for intrinsic events contain the index of the Device Entry that generated the event. This patch updates the Unsolicited Response event handlers to extract the device entry index from the response and pass it to snd_hda_jack_tbl_get_from_tag(). This patch updates snd_hda_jack_tbl_new() to take a dev_id argument and store it in the jack structure, and to make sure not to generate a different tag when called more than once for the same nid.

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.

Convert 'alloc_obj' family to use the new default GFP_KERNEL argument This was done entirely with mindless brute force, using git grep -l '\<k[vmz]*alloc_objs*(.*, GFP_KERNEL)' | xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/' to convert the new alloc_obj() users that had a simple GFP_KERNEL argument to just drop that argument. Note that due to the extreme simplicity of the scripting, any slightly more complex cases spread over multiple lines would not be triggered: they definitely exist, but this covers the vast bulk of the cases, and the resulting diff is also then easier to check automatically. For the same reason the 'flex' versions will be done as a separate conversion. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

ALSA: hda - Fix bad dereference of jack object The hda_jack_tbl entries are managed by snd_array for allowing multiple jacks. It's good per se, but the problem is that struct hda_jack_callback keeps the hda_jack_tbl pointer. Since snd_array doesn't preserve each pointer at resizing the array, we can't keep the original pointer but have to deduce the pointer at each time via snd_array_entry() instead. Actually, this resulted in the deference to the wrong pointer on codecs that have many pins such as CS4208. This patch replaces the pointer to the NID value as the search key. As an unexpected good side effect, this even simplifies the code, as only NID is needed in most cases. Cc: <stable@vger.kernel.org> Signed-off-by: Takashi Iwai <tiwai@suse.de>

ALSA: hda - Add DP-MST jack support This patch adds DP-MST jack support which will be used on NVIDIA platforms. Today, DP-MST audio is supported only if the codec has acomp support. This patch makes it possible to add DP-MST support for non-acomp codecs. For the codecs supporting DP-MST audio, each pin can contain several device entries. Each device entry is a virtual pin, described by pin_nid and dev_id in struct hdmi_spec_per_pin. For monitor hotplug event handling, non-acomp codecs enable and register jack-detection for every hdmi_spec_per_pin. This patch updates every relevant function in hda_jack.h and its implementation in hda_jack.c, to consider dev_id along with pin_nid. Changes to the HD Audio specification to support DP-MST audio are described in the Intel Document Change Notification (DCN) number HDA040-A. From HDA040-A, "For the case of multi stream capable Digital Display Pin Widget, [the Get Pin Sense verb] can be used to read a specific Device Entry state as reported in Get Device List Entry verb." This patch updates the read_pin_sense() function to take the dev_id as an argument and pass it as a parameter to the Get Pin Sense verb. Bits 15 through 20 from the Unsolicited Response for intrinsic events contain the index of the Device Entry that generated the event. This patch updates the Unsolicited Response event handlers to extract the device entry index from the response and pass it to snd_hda_jack_tbl_get_from_tag(). This patch updates snd_hda_jack_tbl_new() to take a dev_id argument and store it in the jack structure, and to make sure not to generate a different tag when called more than once for the same nid.

ALSA: hda - bind headset buttons to the headphone jack With the HDA driver, if the headset buttons are supported, an audio Jack will be created for them. This audio Jack is a bit confusing to users since it can't report headphone/mic insertion events but it claims to support these events. And in addition, the driver already builds a headphone Jack and a mic Jack, and most of those buttons are used for headphone playback, so do some change to bind those buttons to the headphone Jack. After this change, the key events are generated from NID 0x55, and are reported to the input layer via headphone jack (NID 0x21). If there is no headphone Jack, then build an audio jack to support those buttons same as previously.

ALSA: hda - Integrate input-jack stuff into kctl-jack Instead of managing input-jack stuff separately, call all stuff inside the kctl-jack creation, deletion and report. The caller no longer needs to care about input-jack. The better integration between input-jack and kctl-jack should be done in the upper layer in near future, but for now, it's implemented locally for more tests.

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 jack button support Extend some structs to add the support for jack button changes. Now snd_hda_jack_add_kctl() receives two more arguments: the jack type and the jack keymaps. Both are optional, and when zero are passed, the function behaves just like before. For reporting button state changes, you'd need to update jack->button_state bits accordingly, typically in the jack callback. Then the value OR'ed with button_state and the jack plug state is passed to snd_jack_report(). Note that currently the code assumes only the one-shot button events, i.e. it tries to send the button release soon after sending the button event. If a driver really supports the button release handling by itself, we may need to introduce some flag to control this behavior in future. Signed-off-by: Takashi Iwai <tiwai@suse.de>

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. 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 - Fix index number conflicts of phantom jacks Since some jack controls may be renamed as phantom jacks, the existing check for index conflicts doesn't work because it simply compares the name with the last used name, assuming that the controls with the same name continue. Thus, it would result in the duplicated controls when two or more phantom jacks with the very same type exist, and the driver gives up with an error. This patch fixes the problem by checking the index number conflicts more intensively (but dumbly). Signed-off-by: Takashi Iwai <tiwai@suse.de>

ALSA: hda - Allow multiple callbacks for jack So far, hda_jack infrastructure allows only one callback per jack, and this makes things slightly complicated when a driver wants to assign multiple tasks to a jack, e.g. the standard auto-mute with a power up/down sequence. This can be simplified if the hda_jack accepts multiple callbacks. This patch is such an extension: the callback-specific part (the function and private_data) is split to another struct from hda_jack_tbl, and multiple such objects can be assigned to a single hda_jack_tbl entry. The new struct hda_jack_callback is passed to each callback function now, thus the patch became bigger than expected. But these changes are mostly trivial. Signed-off-by: Takashi Iwai <tiwai@suse.de>

ALSA: hda - Add DP-MST jack support This patch adds DP-MST jack support which will be used on NVIDIA platforms. Today, DP-MST audio is supported only if the codec has acomp support. This patch makes it possible to add DP-MST support for non-acomp codecs. For the codecs supporting DP-MST audio, each pin can contain several device entries. Each device entry is a virtual pin, described by pin_nid and dev_id in struct hdmi_spec_per_pin. For monitor hotplug event handling, non-acomp codecs enable and register jack-detection for every hdmi_spec_per_pin. This patch updates every relevant function in hda_jack.h and its implementation in hda_jack.c, to consider dev_id along with pin_nid. Changes to the HD Audio specification to support DP-MST audio are described in the Intel Document Change Notification (DCN) number HDA040-A. From HDA040-A, "For the case of multi stream capable Digital Display Pin Widget, [the Get Pin Sense verb] can be used to read a specific Device Entry state as reported in Get Device List Entry verb." This patch updates the read_pin_sense() function to take the dev_id as an argument and pass it as a parameter to the Get Pin Sense verb. Bits 15 through 20 from the Unsolicited Response for intrinsic events contain the index of the Device Entry that generated the event. This patch updates the Unsolicited Response event handlers to extract the device entry index from the response and pass it to snd_hda_jack_tbl_get_from_tag(). This patch updates snd_hda_jack_tbl_new() to take a dev_id argument and store it in the jack structure, and to make sure not to generate a different tag when called more than once for the same nid.

This audio Jack is a bit confusing to users since it can't report headphone/mic insertion events but it claims to support these events. And in addition, the driver already builds a headphone Jack and a mic Jack, and most of those buttons are used for headphone playback, so do some change to bind those buttons to the headphone Jack. After this change, the key events are generated from NID 0x55, and are reported to the input layer via headphone jack (NID 0x21). If there is no headphone Jack, then build an audio jack to support those buttons same as previously.
