snd_soc_card_get_kcontrol() must be holding a read lock on card->controls_rwsem while walking the controls list. Compare with snd_ctl_find_numid(). The existing function is renamed snd_soc_card_get_kcontrol_locked() so that it can be called from contexts that are already holding card->controls_rwsem (for example, control get/put functions). There are few direct or indirect callers of snd_soc_card_get_kcontrol(), and most are safe. Three require changes, which have been included in this patch: codecs/cs35l45.c: cs35l45_activate_ctl() is called from a control put() function so is changed to call snd_soc_card_get_kcontrol_locked(). codecs/cs35l56.c: cs35l56_sync_asp1_mixer_widgets_with_firmware() is called from control get()/put() functions so is changed to call snd_soc_card_get_kcontrol_locked(). fsl/fsl_xcvr.c: fsl_xcvr_activate_ctl() is called from three places, one of which already holds card->controls_rwsem: 1. fsl_xcvr_mode_put(), a control put function, which will already be holding card->controls_rwsem. 2. fsl_xcvr_startup(), a DAI startup function. 3. fsl_xcvr_shutdown(), a DAI shutdown function. To fix this, fsl_xcvr_activate_ctl() has been changed to call snd_soc_card_get_kcontrol_locked() so that it is safe to call directly from fsl_xcvr_mode_put(). The fsl_xcvr_startup() and fsl_xcvr_shutdown() functions have been changed to take a read lock on card->controls_rsem() around calls to fsl_xcvr_activate_ctl(). While this is not very elegant, it keeps the change small, to avoid this patch creating a large collateral churn in fsl/fsl_xcvr.c. Analysis of other callers of snd_soc_card_get_kcontrol() is that they do not need any changes, they are not holding card->controls_rwsem when they call snd_soc_card_get_kcontrol(). Direct callers of snd_soc_card_get_kcontrol(): fsl/fsl_spdif.c: fsl_spdif_dai_probe() - DAI probe function fsl/fsl_micfil.c: voice_detected_fn() - IRQ handler Indirect callers via soc_component_notify_control(): codecs/cs42l43: cs42l43_mic_shutter() - IRQ handler codecs/cs42l43: cs42l43_spk_shutter() - IRQ handler codecs/ak4118.c: ak4118_irq_handler() - IRQ handler codecs/wm_adsp.c: wm_adsp_write_ctl() - not currently used Indirect callers via snd_soc_limit_volume(): qcom/sc8280xp.c: sc8280xp_snd_init() - DAIlink init function ti/rx51.c: rx51_aic34_init() - DAI init function I don't have hardware to test the fsl/*, qcom/sc828xp.c, ti/rx51.c and ak4118.c changes.

In the case where __lpass_get_dmactl_handle is called and the driver id dai_id is invalid the pointer dmactl is not being assigned a value, and dmactl contains a garbage value since it has not been initialized and so the null check may not work. Fix this to initialize dmactl to NULL. One could argue that modern compilers will set this to zero, but it is useful to keep this initialized as per the same way in functions __lpass_platform_codec_intf_init and lpass_cdc_dma_daiops_hw_params.

The driver must write 0 to HALO_STATE before sending the SYSTEM_RESET command to the firmware. HALO_STATE is in DSP memory, which is preserved across a soft reset. The SYSTEM_RESET command does not change the value of HALO_STATE. There is period of time while the CS35L56 is resetting, before the firmware has started to boot, where a read of HALO_STATE will return the value it had before the SYSTEM_RESET. If the driver does not clear HALO_STATE, this would return BOOT_DONE status even though the firmware has not booted. Signed-off-by:

The ACPI in some SoundWire laptops has a spk-id-gpios property but it points to the wrong Device node. This patch adds a workaround to try to get the GPIO directly from the correct Device node. If the attempt to get the GPIOs from the property fails, the workaround looks for the SDCA node "AF01", which is where the GpioIo resource is defined. If this exists, a spk-id-gpios mapping is added to that node and then the GPIO is got from that node using the property. Signed-off-by:

When the system is suspended while audio is active, the sof_ipc4_pcm_hw_free() is invoked to reset the pipelines since during suspend the DSP is turned off, streams will be re-started after resume. If the firmware crashes during while audio is running (or when we reset the stream before suspend) then the sof_ipc4_set_multi_pipeline_state() will fail with IPC error and the state change is interrupted. This will cause misalignment between the kernel and firmware state on next DSP boot resulting errors returned by firmware for IPC messages, eventually failing the audio resume. On stream close the errors are ignored so the kernel state will be corrected on the next DSP boot, so the second boot after the DSP panic. If sof_ipc4_trigger_pipelines() is called from sof_ipc4_pcm_hw_free() then state parameter is SOF_IPC4_PIPE_RESET and only in this case. Treat a forced pipeline reset similarly to how we treat a pcm_free by ignoring error on state sending to allow the kernel's state to be consistent with the state the firmware will have after the next boot.

4 fixes / cleanups to the rt5645 mc driver's codec_name handling: 1. In the for loop looking for the dai_index for the codec, replace card->dai_link[i] with cht_dailink[i]. The for loop already uses ARRAY_SIZE(cht_dailink) as bound and card->dai_link is just a pointer to cht_dailink using card->dai_link only obfuscates that cht_dailink is being modified directly rather then say a copy of cht_dailink. Using cht_dailink[i] also makes the code consistent with other machine drivers. 2. Don't set cht_dailink[dai_index].codecs->name in the for loop, this immediately gets overridden using acpi_dev_name(adev) directly below the loop. 3. Add a missing break to the loop. 4. Remove the now no longer used (only set, never read) codec_name field from struct cht_mc_private. Signed-off-by:

The driver never uses the IRQ1_CFG register so there's no need to provide a default value. It's set as a readable register only for debugging through the regmap registers file. A system-specific firmware could overwrite this register with a non-default value. Therefore the driver can't hardcode what the initial value actually is. As the register is only for debugging the value can be left unknown until someone wants to read it through debugfs. Signed-off-by:

With the change in the widget free logic to power down the cores only when the scheduler widgets are freed, we need to ensure that the scheduler widget is freed only after all the widgets associated with the scheduler are freed. This is to ensure that the secondary core that the scheduler is scheduled to run on is kept powered on until all widgets that need them are in use. While this works well for dynamic pipelines, in the case of static pipelines the current logic does not take this into account and frees all widgets in the order they occur in the widget_list. So, modify this to ensure that the scheduler widgets are freed only after all other types of widgets in the widget_list are freed.

Rewrite the handling of ASP1 TX mixer mux initialization to prevent a deadlock during component_remove(). The firmware can overwrite the ASP1 TX mixer registers with system-specific settings. This is mainly for hardware that uses the ASP as a chip-to-chip link controlled by the firmware. Because of this the driver cannot know the starting state of the ASP1 mixer muxes until the firmware has been downloaded and rebooted. The original workaround for this was to queue a work function from the dsp_work() job. This work then read the register values (populating the regmap cache the first time around) and then called snd_soc_dapm_mux_update_power(). The problem with this is that it was ultimately triggered by cs35l56_component_probe() queueing dsp_work, which meant that it would be running in parallel with the rest of the ASoC component and card initialization. To prevent accessing DAPM before it was fully initialized the work function took the card mutex. But this would deadlock if cs35l56_component_remove() was called before the work job had completed, because ASoC calls component_remove() with the card mutex held. This new version removes the work function. Instead the regmap cache and DAPM mux widgets are initialized the first time any of the associated ALSA controls is read or written. Signed-off-by:

Remove an unused stub function that calls a non-existant function. This function was accidentally added as part of commit 2144833e ("ALSA: hda: cirrus_scodec: Add KUnit test"). It was a relic of an earlier version of the test that should have been removed. Signed-off-by:

Check whether the firmware is already patched. If so, include the firmware version in the firmware file name. If the firmware has already been patched by the BIOS the driver can only replace it if it has control of hard RESET. If the driver cannot replace the firmware, it can still load a wmfw (for ALSA control definitions) and/or a bin (for additional tunings). But these must match the version of firmware that is running on the CS35L56. The firmware is pre-patched if either: - FIRMWARE_MISSING == 0, or - it is a secured CS35L56 (which implies that is was already patched), cs35l56_hw_init() will set preloaded_fw_ver to the (non-zero) firmware version if either of these conditions is true. Normal (unpatched or replaceable firmware): cs35l56-rev-dsp1-misc[-system_name].[wmfw|bin] Preloaded firmware: cs35l56-rev[-s]-VVVVVV-dsp1-misc[-system_name].[wmfw|bin] Where: [-s] is an optional -s added into the name for a secured CS35L56 VVVVVV is the 24-bit firmware version in hexadecimal. Backport note: This won't apply to kernel versions older than v6.6. Signed-off-by:

Change the filename field layout to: cs35l56-rev[-s]-dsp1-misc[-sub].[wmfw|bin] This is to keep the same firmware file naming scheme as the CS35L56 ASoC driver. This is not a compatibility break because no firmware files have been published. The original field layout matched the ASoC driver, but the way the ASoC driver used the wm_adsp driver config to form this filename was bugged. Fixing the ASoC driver to use the correct wm_adsp config strings means that the 's' flag (to indicate a secured part) has to move to somewhere after the first '-'. Signed-off-by:

Check for the cases of system-specific bin file without a wmfw before falling back to looking for a generic wmfw. All system-specific options should be tried before falling back to loading a generic wmfw/bin. With the original code, the presence of a fallback generic wmfw on the filesystem would prevent using a system-specific tuning with a ROM firmware. Signed-off-by:

The original 50ms timeout for firmware boot is not long enough for worst-case time to reboot after a firmware download. Increase the timeout to 250ms. Signed-off-by:

If the "spk-id-gpios" property is present it points to GPIOs whose value must be used to select the correct bin file to match the speakers. Some manufacturers use multiple sources of speakers, which need different tunings for best performance. On these models the type of speaker fitted is indicated by the values of one or more GPIOs. The number formed by the GPIOs identifies the tuning required. The speaker ID must be used in combination with the subsystem ID (either from PCI SSID or cirrus,firmware-uid property), because the GPIOs can only indicate variants of a specific model.

Check during initialization whether the firmware is already patched. If so, include the firmware version in the wm_adsp fwf_name string. If the firmware has already been patched by the BIOS the driver can only replace it if it has control of hard RESET. If the driver cannot replace the firmware, it can still load a wmfw (for ALSA control definitions) and/or a bin (for additional tunings). But these must match the version of firmware that is running on the CS35L56. The firmware is pre-patched if FIRMWARE_MISSING == 0. Including the firmware version in the fwf_name string will qualify the firmware file name: Normal (unpatched or replaceable firmware): cs35l56-rev-dsp1-misc[-system_name].[wmfw|bin] Preloaded firmware: cs35l56-rev[-s]-VVVVVV-dsp1-misc[-system_name].[wmfw|bin] Where: [-s] is an optional -s added into the name for a secured CS35L56 VVVVVV is the 24-bit firmware version in hexadecimal.
