* ALSA: hda - Re-add the lost fake mute supportTakashi Iwai2015-06-11
| | | | | | | | | | | | | | Yet another regression by the transition to regmap cache; for better usability, we had the fake mute control using the zero amp value for Conexant codecs, and this was forgotten in the new hda core code. Since the bits 4-7 are unused for the amp registers (as we follow the syntax of AMP_GET verb), the bit 4 is now used to indicate the fake mute. For setting this flag, snd_hda_codec_amp_update() becomes a function from a simple macro. The bonus is that it gained a proper function description. Signed-off-by: Takashi Iwai <tiwai@suse.de>
* ALSA: hda - Use regmap for parameter caches, tooTakashi Iwai2015-03-23
| | | | | | | | | | | | | | | | | The amp hash table was used for recording the cached reads of some capability values like pin caps or amp caps. Now all these are moved to regmap as well. One addition to the regmap helper is codec->caps_overwriting flag. This is set in snd_hdac_override_parm(), and the regmap helper accepts any register while this flag is set, so that it can overwrite even the read-only verb like AC_VERB_PARAMETERS. The flag is cleared immediately in snd_hdac_override_parm(), as it's a once-off flag. Along with these changes, the no longer needed amp hash and relevant fields are removed from hda_codec struct now. Signed-off-by: Takashi Iwai <tiwai@suse.de>
* ALSA: hda - Use regmap for amp accessesTakashi Iwai2015-03-23
| | | | | | | | | | | | | | This patch converts the amp access functions to the regmap helpers. The amp values were formerly cached in the own hash table. Now it's dropped by the regmap's cache. The only tricky conversion is snd_hda_codec_amp_init(). This function shouldn't do anything if the amp was already initialized. For achieving this behavior, a value is read once at first temporarily in the cache-only mode. Only if it returns an error, i.e. the item still doesn't exist in the cache, it proceeds to the update.

* ALSA: hda - Fix possible runtime PM refcount unbalanceTakashi Iwai2015-03-23
| | | | | | | | | | | When the driver is unloaded before the codec is bound, it still keeps the runtime PM refcount up, and results in the unbalance. This patch covers these cases by introducing a flag indicating the runtime PM initialization and handling the codec registration procedure more properly. It also fixes the missing input beep device as a gratis, too. Signed-off-by: Takashi Iwai <tiwai@suse.de>
* ALSA: hda - Move a part of hda_codec stuff into hdac_deviceTakashi Iwai2015-03-23
| | | | | | | | | | Now some codes and functionalities of hda_codec struct are moved to hdac_device struct. A few basic attributes like the codec address, vendor ID number, FG numbers, etc are moved to hdac_device, and they are accessed like codec->core.addr. The basic verb exec functions are moved, too.

* ALSA: hda - Implement unbind more safelyTakashi Iwai2015-03-03
| | | | | | | | | | | | Now we have all pieces ready, and put them into places: - add the hda_pcm refcount to azx_pcm_open() and azx_pcm_close(), - call the most of cleanup code in hda_codec_reset() from the codec driver remove, - call the same code also from the hda_codec object free. Then the codec driver can be unbound more safely now. Signed-off-by: Takashi Iwai <tiwai@suse.de>

* ALSA: hda - Bind codecs via standard busTakashi Iwai2015-02-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now we create the standard HD-audio bus (/sys/bus/hdaudio), and bind the codec driver with the codec device over there. This is the first step of the whole transition so that the changes to each codec driver are kept as minimal as possible. Each codec driver needs to register hda_codec_driver struct containing the currently existing preset via the new helper macro module_hda_codec_driver(). The old hda_codec_preset_list is replaced with this infrastructure. The generic parsers (for HDMI and other) are also included in the preset with the special IDs to bind uniquely. In HD-audio core side, the device binding code is split to hda_bind.c. It provides the snd_hda_bus_type implementation to match the codec driver with the given codec vendor ID. It also manages the module auto-loading by itself like before: when the matching isn't found, it tries to probe the corresponding codec modules, and finally falls back to the generic drivers. (The special ID mentioned above is set at this stage.) The only visible change to outside is that the hdaudio sysfs entry now appears in /sys/bus/devices, not as a sound class device. More works to move the suspend/resume and remove ops will be (hopefully) done in later patches. Signed-off-by: Takashi Iwai <tiwai@suse.de>
* ALSA: hda - Embed struct hda_bus_unsolicited into struct hda_busTakashi Iwai2015-02-17
| | | | | | | | There is no big merit to handle hda_bus_unsolicited object individually, as it's tightly coupled with the hda_bus object itself. Embedding it makes the code simpler in the end. Signed-off-by: Takashi Iwai <tiwai@suse.de>

| | | | | | | | | | | | Without this terminating entry, the pin matching would continue across random memory until a zero or a non-matching entry was found.

* ALSA: hda - Add a new quirk match based on default pin configurationDavid Henningsson2014-05-26
| | | | | | | | | | | | | | | | Normally, we match on pci ssid only. This works but needs new code for every machine. To catch more machines in the same quirk, let's add a new type of quirk, where we match on 1) PCI Subvendor ID (i e, not device, just vendor) 2) Codec ID 3) Pin configuration default If all these three match, we could be reasonably certain that the quirk should apply to the machine even though it might not be the exact same device.

* ALSA: hda - Replace with standard printkTakashi Iwai2014-02-25
| | | | | | | | | | | | Use dev_err() and co for messages from HD-audio controller and codec drivers. The codec drivers are mostly bound with codec objects, so some helper macros, codec_err(), codec_info(), etc, are provided. They merely wrap the corresponding dev_xxx(). There are a few places still calling snd_printk() and its variants as they are called without the codec or device context. Signed-off-by: Takashi Iwai <tiwai@suse.de>
* ALSA: hda - Add sysfs to codec object, tooTakashi Iwai2014-02-25
| | | | | | | | | | | | We have currently sysfs attributes for each hwdep, but basically these should belong to the codec itself, per se. Let's add them to the codec object while keeping them for hwdep as is for compatibility. While we are at it, split the sysfs-related stuff into a separate source file, hda_sysfs.c, and keep only the stuff necessary for hwdep in hda_hwdep.c. Signed-off-by: Takashi Iwai <tiwai@suse.de>
* ALSA: Create sysfs attribute files via groupsTakashi Iwai2014-02-25
| | | | | | | | | | | | Instead of calling each time device_create_file(), create the groups of sysfs attribute files at once in a normal way. Add a new helper function, snd_get_device(), to return the associated device object, so that we can handle the sysfs addition locally. Since the sysfs file addition is done differently now, snd_add_device_sysfs_file() helper function is removed. Signed-off-by: Takashi Iwai <tiwai@suse.de>
* ALSA: hda - Bind with HDMI codec parser automaticallyTakashi Iwai2013-11-26

* ALSA: hda - hdmi: Add ELD emulation for ATI/AMD codecsAnssi Hannula2013-10-24
| | | | | | | | | | | | | | | | | | | | | | | | | ATI/AMD HDMI/DP codecs do not include standard HDA ELD (EDID-like data) support. In place of providing access to an ELD buffer, various vendor-specific verbs are provided to provide the relevant information. Revision ID 3 and later (0x100300 as reported by procfs codec#X) have support for providing more information than the previous revisions (but only if supported by the display driver). Generate ELD from the information provided by the vendor-specific verbs on ATI/AMD codecs.

* ALSA: hda - Move mutex from hda_eld to per_pin in HDMI codec driverTakashi Iwai2013-10-17
| | | | | | | | | | | | | | Since the lock is used primarily in patch_hdmi.c, it's better to move it in the local struct instead of exporting in hda_eld. The only functions requiring the lock in hda_eld.c are proc accessors. So in this patch, the proc entry and its creation/deletion/accessors are moved into patch_hdmi.c, together with the mutex lock to pin_spec struct. The former proc info functions are exported so that they can be called from patch_hdmi.c. Signed-off-by: Takashi Iwai <tiwai@suse.de>

* ALSA: hda - Fix missing Mic Boost controls for VIA codecsTakashi Iwai2013-06-19
| | | | | | | | | | | | | | | | | Some VIA codecs like VT1708S have Mic boost amps in the mic pins but they aren't exposed in the capability bits. In the past driver code, we override the pin caps and create mic boost controls forcibly. While transition to the generic parser, we lost the mic boost controls although the pin caps are still overridden, because the generic parser code checks the widget caps, too. So this patch adds a new helper function to allow the override of the given widget capability bits, and makes VIA codecs driver to add the missing input-amp capability bit.

* ALSA: hda - Fix return value of snd_hda_check_power_state()Takashi Iwai2013-06-18
| | | | | | | | | | | | | | The refactoring by commit 9040d102 introduced the new function snd_hda_check_power_state(). This function is supposed to return true if the state already reached to the target state, but it actually returns false for that. An utterly stupid typo while copy & paste. Fortunately this didn't influence on much behavior because powering up AFG usually powers up the child widgets, too. But the finer power control must have been broken by this bug.

* ALSA: hda - Don't apply EAPD power filter as defaultTakashi Iwai2013-03-13
| | | | | | | | | | | | | | | | | | | | | So far, the driver doesn't power down the widget at going down to D3 when the widget node has an EAPD capability and EAPD is actually set on all codecs unless codec->power_filter is set explicitly. This caused a problem on some Conexant codecs, leading to click noises, and we set it as NULL there. But it is very unlikely that the problem hits only these codecs. Looking back at the development history, this workaround for EAPD was introduced just for some laptops with STAC9200 codec, then we applied it blindly for all. Now, since it's revealed to have an ill effect, we should disable this workaround per default and apply only for the known requiring systems. The EAPD workaround is implemented now as snd_hda_codec_eapd_power_filter(), and this has to be set explicitly by the codec driver when needed. As of now, only patch_stac9200() sets this one.

* ALSA: hda - hdmi: Protect ELD bufferDavid Henningsson2013-02-19
| | | | | | | | | | | | Because the eld buffer can be simultaneously accessed from both workqueue context (updating) and process context (kcontrol read), we need to protect it with a mutex to guarantee consistency.

| | | | | | | | | | | | | Add a new fixup type, HDA_FIXUP_PINCTLS, for overriding the pinctl values of the given pins. It takes the same array of struct pintbl like HDA_FIXUP_PINS, but each entry contains the pinctl value instead of the pin default config value. This patch also replaces the corresponding codes in patch_realtek.c. Without this change, the direct call of verbs may be overridden again by the later call of pinctl restoration by the driver.

* ALSA: hda - Introduce cache & flush cmd / amp writesTakashi Iwai2013-01-12
| | | | | | | | | | | | | | | | | | | | | | | | | For optimizing the verb executions, a new mechanism to cache the verbs and amp update commands is introduced. With the new "write to cache and flush" way, you can reduce the same verbs that have been written multiple times. When codec->cached_write flag is set, the further snd_hda_codec_write_cache() and snd_hda_codec_amp_stereo() calls will be performed only on the command or amp cache table, but not sent to the hardware yet. Once after you call all commands and update amps, call snd_hda_codec_resume_amp() and snd_hda_codec_resume_cache(). Then all cached writes and amp updates will be written to the hardware, and the dirty flags are cleared. In this implementation, the existing cache table is reused, so actually no big code change is seen here. Each cache entry has a new dirty flag now (so the cache key is now reduced to 31bit). As a good side-effect by this change, snd_hda_codec_resume_*() will no longer execute verbs that have been already issued during the resume phase by checking the dirty flags.

This patch introduces a (hackish and ugly) workaround: the IEC958 controls for the SPDIF device are re-labeled with device=1 when HDMI coexists. The device=1 corresponds to the actual PCM device for SPDIF, so it's anyway a better representation. In future, HDMI controls should be moved with the corresponding PCM device number, too.

These are simple replacement of the codec verb write with AC_VERB_SET_PIN_WIDGET but do more sanity checks and filter out superfluous pin-control bits if they don't fit with the corresponding pin capabilities. Some codecs are screwed up or ignore the command when such a wrong bit is set. These helpers will avoid such secret errors. Signed-off-by: Takashi Iwai <tiwai@suse.de>
