ASoC: SOF: Intel: hda: Remove MODULE_SOFTDEP for snd-hda-codec-hdmi

2026-01-20T12:17:34+00:00

The sofdep no longer works due to the reworked HDA audio stack and it was an incorrect way to try to work around system security policy blocking request_module use, even if they are legitimate. Drop the softdep to stop the whack-a-mole hacking around system configuration issues. Revert "ASoC: SOF: Intel: hda: add softdep pre to snd-hda-codec-hdmi module" This reverts commit 33b7dc7843dbdc9b90c91d11ba30b107f9138ffd.

ASoC: SOF: Intel: split codec mask detect and programming UNSOL

2025-08-29T08:50:36+00:00

We only need to detect codec mask in probe, but need to program UNSOL in probe and resume. We will detect codec mask and program UNSOL separately in the follow up commit.

module: Convert symbol namespace to string literal

Clean up the existing export namespace code along the same lines of commit 33def8498fdd ("treewide: Convert macro and uses of __section(foo) to __section("foo")") and for the same reason, it is not desired for the namespace argument to be a macro expansion itself.

ASoC: SOF: Intel: hda-codec: preserve WAKEEN values

2024-04-04T19:25:39+00:00

Since LunarLake, we use the HDadio WAKEEN/WAKESTS to detect wakes for SoundWire codecs. Unfortunately, the existing code in hda_codec_jack_wake_enable() unconditionally resets the WAKEEN bits. This patch changes the initialization to preserve SoundWire WAKEEN bits. For HDAudio codecs the same strategy is used, WAKEEN is only set when the jacktbl.used property is set.

ASoC: SOF: Intel: hda-codec: Delay the codec device registration

2024-01-03T14:33:01+00:00

The current code flow is: 1. snd_hdac_device_register() 2. set parameters needed by the hdac driver 3. request_codec_module() the hdac driver is probed at this point During boot the codec drivers are not loaded when the hdac device is registered, it is going to be probed later when loading the codec module, which point the parameters are set. On module remove/insert rmmod snd_sof_pci_intel_tgl modprobe snd_sof_pci_intel_tgl The codec module remains loaded and the driver will be probed when the hdac device is created right away, before the parameters for the driver has been configured: 1. snd_hdac_device_register() the hdac driver is probed at this point 2. set parameters needed by the hdac driver 3. request_codec_module() will be a NOP as the module is already loaded Move the snd_hdac_device_register() later, to be done right before requesting the codec module to make sure that the parameters are all set before the device is created: 1. set parameters needed by the hdac driver 2. snd_hdac_device_register() 3. request_codec_module() This way at the hdac driver probe all parameters will be set in all cases.

ASoC: SOF: Intel: hda-codec: fix possible memory leak in hda_codec_device_init()

2022-11-02T11:39:05+00:00

If snd_hdac_device_register() fails, 'codec' and name allocated in dev_set_name() called in snd_hdac_device_init() are leaked. Fix this by calling put_device(), so they can be freed in snd_hda_codec_dev_release() and kobject_cleanup().
