* ALSA: hda - fix headset mic detection problem for one more machineHui Wang2015-04-241-9/+15

* ALSA: hda - fix "num_steps = 0" error on ALC256David Henningsson2015-04-211-2/+3
| | | | | | | | | | | | | | | | The ALC256 does not have a mixer nid at 0x0b, and there's no loopback path (the output pins are directly connected to the DACs). This commit fixes an "num_steps = 0 for NID=0xb (ctl = Beep Playback Volume)" error (and as a result, problems with amixer/alsamixer). If there's pcbeep functionality, it certainly isn't controlled by setting an amp on 0x0b, so disable beep functionality (at least for now).

* ALSA: hda - add AZX_DCAPS_I915_POWERWELL to BaytrailMengdong Lin2015-04-211-1/+4
| | | | | | | | | | | | | | | | | | | | | | This patch addes AZX_DCAPS_I915_POWERWELL to BYT (Baytrail). Like Braswell and Skylake, the HDMI codec on Bytrail is also in the shared power well with GPU. This power well must be turned on before we reset link to probe the codec, to avoid communication failure with the codec. The side effect is that this power is always ON in S0 because the BYT HDMI codec does not support EPSS or D3ClkStop and so the controller doesn't enter D3 at runtime, and the HDMI codec and analog codec share a single physical HD-A link and so we cannot reset the HD-A link freely when we re-enable the power to use the HDMI codec. Next step is to test if an AGP reset or double AGP reset on BYT HDMI codec is okay to bring the HDMI codec back to a functional state after restoring the power. If okay, we can bind the power on/off with the HDMI codec PM without interrupting the analog audio. Signed-off-by: Mengdong Lin <mengdong.lin@intel.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
* ALSA: hda - only sync BCLK to the display clock for Haswell & BroadwellMengdong Lin2015-04-201-0/+6
| | | | | | | | | | | | | Only Intel Haswell and Broadwell have a separate HD-A controller (PCI device 3) for display audio, which needs to get 24MHz HD-A link BCLK from the variable display core clock through vendor specific registers EM4 & EM5. Other platforms (Baytrail, Braswell and Skylake) don't have this feature. So this patch checks the PCI device ID of the controller in haswell_set_bclk() and only sync BCLK for HSW and BDW.

| * ALSA: hda - Work around races of power up/down with runtime PMTakashi Iwai2015-04-084-12/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, snd_hdac_power_up()/down() helpers checks whether the codec is being in pm (suspend/resume), and skips the call of runtime get/put during it. This is needed as there are lots of power up/down sequences called in the paths that are also used in the PM itself. An example is found in hda_codec.c::codec_exec_verb(), where this can power up the codec while it may be called again in its power up sequence, too. The above works in most cases, but sometimes we really want to wait for the real power up. For example, the control element get/put may want explicit power up so that the value change is assured to reach to the hardware. Using the current snd_hdac_power_up(), however, results in a race, e.g. when it's called during the runtime suspend is being performed. In the worst case, as found in patch_ca0132.c, it can even lead to the deadlock because the code assumes the power up while it was skipped due to the check above. For dealing with such cases, this patch makes snd_hdac_power_up() and _down() to two variants: with and without in_pm flag check. The version with pm flag check is named as snd_hdac_power_up_pm() while the version without pm flag check is still kept as snd_hdac_power_up(). (Just because the usage of the former is fewer.) Then finally, the patch replaces each call potentially done in PM with the new _pm() variant. In theory, we can implement a unified version -- if we can distinguish the current context whether it's in the pm path. But such an implementation is cumbersome, so leave the code like this a bit messy way for now...

But this conversion needs a bit more caution than before. - In the old code, we just record any verbs as is, and restore them at resume. For the regmap scheme, this doesn't work, since a few verbs like AMP or DIGI_CONVERT are asymmetrical. Such verbs are converted either to the dedicated function (snd_hda_regmap_xxx_amp()) or changed to the unified verb. - Some verbs have to be declared as vendor-specific ones before accessing via regmap. Also, the minor optimization with codec->cached_write flag is dropped in a few places, as this would confuse the operation. Further optimizations will be brought in the later patches, if any. This conversion ends up with a drop of significant amount of codes, mostly the helper codes that are no longer used. Signed-off-by: Takashi Iwai <tiwai@suse.de>

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>

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. Signed-off-by: Takashi Iwai <tiwai@suse.de>

Because o the asymmetric nature of HD-audio verbs, especially the amp verbs, we need to translate the verbs as a sort of pseudo registers to be mapped uniquely in regmap. In this patch, a pseudo register is built from the NID, the AC_VERB_GET_* and 8bit parameters, i.e. almost in the form to be sent to HD-audio bus but without codec address field. OTOH, for writing, the same pseudo register is translated to AC_VERB_SET_* automatically. The AC_VERB_SET_AMP_* verb is re-encoded from the corresponding AC_VERB_GET_AMP_* verb and parameter at writing. Some verbs has a single command for read but multiple for writes. A write for such a verb is split automatically to multiple verbs. The patch provides also a few handy helper functions. They are designed to be accessible even without regmap. When no regmap is set up (e.g. before the codec device instantiation), the direct hardware access is used. Also, it tries to avoid the unnecessary power-up. The power up/down sequence is performed only on demand. The codec driver needs to call snd_hdac_regmap_exit() and snd_hdac_regmap_exit() at probe and remove if it wants the regmap access. There is one flag added to hdac_device. When the flag lazy_cache is set, regmap helper ignores a write for a suspended device and returns as if it was actually written. It reduces the hardware access pretty much, e.g. when adjusting the mixer volume while in idle. This assumes that the driver will sync the cache later at resume properly, so use it carefully.

| |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We need to cap "ucontrol->id.index / num_busses_in(chip)" so the we don't read beyond the end of the array. I also adding a check on "in" and changing the type in snd_echo_mixer_put() from short to unsigned int. Those changes are done for symmetry and are cosmetic.

| * | ALSA: hda - Re-add tracepoints to HD-audio core driverTakashi Iwai2015-03-232-120/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now let's take the basic tracepoints back to the HD-audio driver. The three bus tracepoints, hda_send_cmd, hda_get_response and hda_unsol_event are revived but in a slightly different form. Since we don't assign the card number there, print the bus device name instead. Signed-off-by: Takashi Iwai <tiwai@suse.de>
| * | ALSA: hda - Fix possible runtime PM refcount unbalanceTakashi Iwai2015-03-234-8/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add an overriding exec_verb op to struct hdac_device so that the call via snd_hdac_exec_verb() can switch to a different route depending on the setup. The codec driver sets this field so that it can handle the errors or applying quirks appropriately. Furthermore, this mechanism will be used for smooth transition for the regmap support in later patches. Signed-off-by: Takashi Iwai <tiwai@suse.de>

Now it shows only a few core parameter, vendor_id, subsystem_id, revision_id, afg, mfg, vendor_name and chip_name. In addition, now a widget tree is added to the bus device sysfs directory for showing the widget topology and attributes. It's just a flat tree consisting of subdirectories named as the widget NID including various attributes like widget capability bits. The AFG (usually NID 0x01) is always found there, and it contains always amp_in_caps, amp_out_caps and power_caps files. Each of these attributes show a single value. The rest are the widget nodes belonging to that AFG. Note that the child node might not start from 0x02 but from another value like 0x0a. Each child node may contain caps, pin_caps, amp_in_caps, amp_out_caps, power_caps and connections files. The caps (representing the widget capability bits) always contain a value. The rest may contain value(s) if the attribute exists on the node. Only connections file show multiple values while other attributes have zero or one single value. An example of ls -R output is like below: % ls -R /sys/bus/hdaudio/devices/hdaudioC0D0/ /sys/bus/hdaudio/devices/hdaudioC0D0/widgets/: 01/ 04/ 07/ 0a/ 0d/ 10/ 13/ 16/ 19/ 1c/ 1f/ 22/ 02/ 05/ 08/ 0b/ 0e/ 11/ 14/ 17/ 1a/ 1d/ 20/ 23/ 03/ 06/ 09/ 0c/ 0f/ 12/ 15/ 18/ 1b/ 1e/ 21/ /sys/bus/hdaudio/devices/hdaudioC0D0/widgets/01: amp_in_caps amp_out_caps power_caps /sys/bus/hdaudio/devices/hdaudioC0D0/widgets/02: amp_in_caps amp_out_caps caps connections pin_caps pin_cfg power_caps /sys/bus/hdaudio/devices/hdaudioC0D0/widgets/03: .....

Note that the codec-side tracing support is disabled temporarily during this transition due to the code shuffling. It will be re-enabled later once when all pieces are settled down.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Define the common hd-audio driver and device types to bind over snd_hda_bus_type publicly. This allows to implement other type of device and driver code over hd-audio bus. Now both struct hda_codec and struct hda_codec_driver inherit these new struct hdac_device and struct hdac_driver, respectively. The bus registration is done in subsys_initcall() to assure it before any other driver registrations. Signed-off-by: Takashi Iwai <tiwai@suse.de>
