[Sound-open-firmware] [PATCH v3 3/4] ASoC: SOF: Intel: hda: Modify existing helper to disable WAKEEN
by Kai-Heng Feng 12 Jan '21

12 Jan '21

Modify hda_codec_jack_wake_enable() to also support disable WAKEEN. In addition, this patch also moves the WAKEEN disablement call out of hda_codec_jack_check() into hda_codec_jack_wake_enable(). This is a preparation for next patch.

[Sound-open-firmware] [PATCH v3 2/4] ASoC: SOF: Intel: hda: Resume codec to do jack detection
by Kai-Heng Feng 12 Jan '21

12 Jan '21

Instead of queueing jackpoll_work, runtime resume the codec to let it use different jack detection methods based on jackpoll_interval. This partially matches SOF driver's behavior with commit a6e7d0a4bdb0 ("ALSA: hda: fix jack detection with Realtek codecs when in D3"), the difference is SOF unconditionally resumes the codec. --- v3: Remove wrong assumption that only Realtek codec is used by SOF. v2: No change. sound/soc/sof/intel/hda-codec.c | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-) diff --git a/sound/soc/sof/intel/hda-codec.c b/sound/soc/sof/intel/hda-codec.c index 6875fa570c2c..df59c79cfdfc 100644 --- a/sound/soc/sof/intel/hda-codec.c +++ b/sound/soc/sof/intel/hda-codec.c @@ -93,8 +93,7 @@ void hda_codec_jack_check(struct snd_sof_dev *sdev) * has been recorded in STATESTS */ if (codec->jacktbl.used) - schedule_delayed_work(&codec->jackpoll_work, - codec->jackpoll_interval); + pm_request_resume(&codec->core.dev); } #else void hda_codec_jack_wake_enable(struct snd_sof_dev *sdev) {} -- 2.29.2

We have many SOF maintainers still out on holidays this week, so let's give some time for people to digest. This is certainly a big change. The version you posted is already sufficient to describe the idea for sure. Br, Kai

This matches SOF driver's behavior with commit a6e7d0a4bdb0 ("ALSA: hda: fix jack detection with Realtek codecs when in D3"). Since SOF only uses Realtek codec, we don't need any additional check for the resume.

CONFIG_SND_SOC_SOF_INTEL_PCI is close, but there is at least one platform that does not use SND_INTEL_DSP_CONFIG. > According to sof_pci_ids[], all PCI IDs are Intel specific, but I can't > tell which ones need the DSP config. Indeed currently all the ids are Intel ones (and with exception of old Merrifield, all use DSP config). But that's just how it is now. > Could it be part of the device specific driver_data? This would certainly be a clean way and allow to remove the Intel-specific calls from sof_pci_probe(). As a short-term solution, IS_REACHABLE() seems ok as well. Br, Kai

It seems that the above if should be modified as: #if IS_BUILDIN(CONFIG_SND_INTEL_DSP_CONFIG) || (defined(MODULE) && IS_MODULE(CONFIG_SND_INTEL_DSP_CONFIG)) So the buildin drivers which do not require the DSP config probe can be compiled without this dependency.

Those calls should be done only if Intel drivers are involved. So, wrapping the call with ifdef CONFIG_SND_SOC_SOF_INTEL_PCI or CONFIG_SND_SOC_SOF_INTEL_ACPI would work better (although those are a bit uglier). thanks, Takashi > --- > include/sound/intel-dsp-config.h | 17 ----------------- > sound/soc/sof/Kconfig | 2 ++ > 2 files changed, 2 insertions(+), 17 deletions(-) > > diff --git a/include/sound/intel-dsp-config.h b/include/sound/intel-dsp-config.h > index d4609077c258..94667e870029 100644 > --- a/include/sound/intel-dsp-config.h > +++ b/include/sound/intel-dsp-config.h > @@ -18,24 +18,7 @@ enum { > SND_INTEL_DSP_DRIVER_LAST = SND_INTEL_DSP_DRIVER_SOF > }; > > -#if IS_ENABLED(CONFIG_SND_INTEL_DSP_CONFIG) > - > int snd_intel_dsp_driver_probe(struct pci_dev *pci); > int snd_intel_acpi_dsp_driver_probe(struct device *dev, const u8 acpi_hid[ACPI_ID_LEN]); > > -#else > - > -static inline int snd_intel_dsp_driver_probe(struct pci_dev *pci) > -{ > - return SND_INTEL_DSP_DRIVER_ANY; > -} > - > -static inline > -int snd_intel_acpi_dsp_driver_probe(struct device *dev, const u8 acpi_hid[ACPI_ID_LEN]) > -{ > - return SND_INTEL_DSP_DRIVER_ANY; > -} > - > -#endif > - > #endif > diff --git a/sound/soc/sof/Kconfig b/sound/soc/sof/Kconfig > index 031dad5fc4c7..051fd3d27047 100644 > --- a/sound/soc/sof/Kconfig > +++ b/sound/soc/sof/Kconfig > @@ -12,6 +12,7 @@ if SND_SOC_SOF_TOPLEVEL > config SND_SOC_SOF_PCI > tristate "SOF PCI enumeration support" > depends on PCI > + select SND_INTEL_DSP_CONFIG > select SND_SOC_SOF > select SND_SOC_ACPI if ACPI > help > @@ -23,6 +24,7 @@ config SND_SOC_SOF_PCI > config SND_SOC_SOF_ACPI > tristate "SOF ACPI enumeration support" > depends on ACPI || COMPILE_TEST > + select SND_INTEL_DSP_CONFIG > select SND_SOC_SOF > select SND_SOC_ACPI if ACPI > select IOSF_MBI if X86 && PCI > -- > 2.29.2 >
