spec->init_hook = alc_default_init; It has default init_hook. I use this to do standard headphone depop function.
Ah, OK. Then we need a call chain from alc294_init(),
static void alc294_init() { coef(); alc294_hp_init(); alc_default_init(); }

Hi Takashi,
But spec->init_hook will call at resume back. alc294_hp_init() function just need to call at one time.
As already mentioned, even if it has to be called only once and does something for the hardware, it'll be missing if the machine goes hibernate (S4) and resume. In S4, the machine boots from scratch and switches immediately to the saved image that calls resume callback. What's worse for us is that this switch happens usually in initrd, i.e. before the sound driver gets loaded. So, the machine goes to resume without processing alc294_hp_init().
IOW, even if it's needed only once, you'll have to call it at resume unless it has a significant drawback.
(Strictly speaking, we may use thaw PM callback, but the HD-audio codec driver doesn't use it, so there is only resume callback for now.)
And it need to call it before call spec->init_hook.
But ALC294 (and ALC700) have no init_hook, so far?
ALC225 also need to call similar procedure. I will post it later.
OK, thanks.

Yes, it only call at probing. Just need to call it at boot time.

Hi Takashi,
Could I move the alc294_hp_init(codec) to below line. Because hp_pin = spec->gen.autocfg.hp_pins[0] was null value when alc294_hp_init(codec) at original line. Or move alc269_parse_auto_config() upward.
It looks OK to me. But this made me wonder whether we don't need to call this function at resume as well? Currently it's called only at probing.
Hrm, but it modifies many COEFs, and are these all preserved with suspend? For example, there is also hibernation (S4), which is a switch from the boot without the audio driver initialization. Then we'll resume from the uninitialized state. I guess other COEF changes in that area should be moved as the additional init hook as well.
Actually, if we do call this at resume, the change would be easier, a patch like below.

No, it not expected. It will enter two times after boot ready. I think it could add a flag in alc225_hp_init(). To make sure it only excute one time. How do you think about?

Where was it called, actually? The call of patch_ops.init is found in several places: once in snd_hda_codec_build_controls() just before creating controls (which is the boot time init), and at resume, alc269_resume().
And, as already explained, we have to call this at resume, because it's not guaranteed that it's been already called in the case of hibernation.

alc225_hp_init() ==> it only need to call one time at boot time. This HP initial code doesn't need to call at resume. If system boot, HP initial code just need to call it at boot time. S3 state was not need to call this function.
But S4 resume must call this function: that's my point.
So the question is whether calling alc225_hp_init() at S3 resume is significantly harmful or not. If not, we can move it there. If it's harmful, we need to distinguish S3 and S4, and introduce either some flag or a new callback, which will be a much more work than simply patching the codec code.

Where was it called, actually? The call of patch_ops.init is found in several places: once in snd_hda_codec_build_controls() just before creating controls (which is the boot time init), and at resume, alc269_resume().
And, as already explained, we have to call this at resume, because it's not guaranteed that it's been already called in the case of hibernation.

Our Windows code just called it at boot time only. SD's programing guide point just need to call one time. So, I don't know it's harmful or not. I will check with our AE and SD. I could also test it with S3 resume state.
Many Thanks. Please wait.

alc225_hp_init() ==> it only need to call one time at boot time. This HP initial code doesn't need to call at resume. If system boot, HP initial code just need to call it at boot time. S3 state was not need to call this function.
But S4 resume must call this function: that's my point.
So the question is whether calling alc225_hp_init() at S3 resume is significantly harmful or not. If not, we can move it there. If it's harmful, we need to distinguish S3 and S4, and introduce either some flag or a new callback, which will be a much more work than simply patching the codec code.

This won't work with S4, unfortunately.
The point of S4 problem is that the switch happens from the uninitialized state to the already running system via a single resume callback. That is, the driver was already initialized in the restored image although the chip is still uninitialized on the booted image before the switch. Then switch happens, and since it keeps done_hp_init=1 at S4 resume call, the whole trick won't be applied at all.
I'll check whether we have some indicator showing that the call is in thaw/restore, or we'd have to implement a separate thaw/restore callback.

This won't work with S4, unfortunately.
The point of S4 problem is that the switch happens from the uninitialized state to the already running system via a single resume callback. That is, the driver was already initialized in the restored image although the chip is still uninitialized on the booted image before the switch. Then switch happens, and since it keeps done_hp_init=1 at S4 resume call, the whole trick won't be applied at all.
I'll check whether we have some indicator showing that the call is in thaw/restore, or we'd have to implement a separate thaw/restore callback.

alc225_hp_init() ==> it only need to call one time at boot time. This HP initial code doesn't need to call at resume. If system boot, HP initial code just need to call it at boot time. S3 state was not need to call this function.
But S4 resume must call this function: that's my point.
So the question is whether calling alc225_hp_init() at S3 resume is significantly harmful or not. If not, we can move it there. If it's harmful, we need to distinguish S3 and S4, and introduce either some flag or a new callback, which will be a much more work than simply patching the codec code.

Where was it called, actually? The call of patch_ops.init is found in several places: once in snd_hda_codec_build_controls() just before creating controls (which is the boot time init), and at resume, alc269_resume().
And, as already explained, we have to call this at resume, because it's not guaranteed that it's been already called in the case of hibernation.

It wasn't clear to me whether you meant this as a success or a failure... Did the patch work as expected, no?
thanks,

Hi Takashi,
So I think put it under alc269 parser. Maybe it is the quickly method.
err = alc269_parse_auto_config(codec); if (err < 0) goto error;

Not really... The init sequence needs to be applied in two different places: once in the init callback, and another in the resume callback but only for the hibernation restore.
The patches below are applied on top of yours, and this should make things working.
The first one lets the HD-audio core recording the currently processed PM event, and the second one evaluates it and applies the missing init sequence also for the hibernation resume.
This isn't quite sexy, but it has the minimal change in the codec driver side. If this requirement is more common, we can think of splitting / reorganizing the codec callbacks to be more directly called from the device pm ops.
thanks,
Takashi

I did quick tests and the test result looks positive, at least, about the PM power_state change tracking. So I'm going to push your fix to for-linus for 5.0, while other two to for-next, for 5.1, as the S4 resume issue isn't any urgent bug and it's no regression, either.
thanks,
Takashi
Many Thanks. ^^
