Current snd_soc_component_driver has pcm_new/pcm_free, but, it doesn't have "component" at parameter. Thus, each callback can't know it is called for which component. Each callback currently is getting "component" by using snd_soc_rtdcom_lookup() with driver name. It works today, but, will not work in the future if we support multi CPU/Codec/Platform, because 1 rtd might have multiple same driver name component. To solve this issue, each callback need to be called with component. This patch adds new pcm_construct/pcm_destruct with "component" parameter.

Current snd_soc_component_driver has snd_pcm_ops, and each driver can have callback via it (1). But, it is mainly created for ALSA, thus, it doesn't have "component" as parameter for ALSA SoC (1)(2). Thus, each callback can't know it is called for which component. Thus, each callback currently is getting "component" by using snd_soc_rtdcom_lookup() with driver name (3). --- ALSA SoC --- ... if (component->driver->ops && component->driver->ops->open) (1) return component->driver->ops->open(substream); ... --- driver --- (2) static int xxx_open(struct snd_pcm_substream *substream) { struct snd_soc_pcm_runtime *rtd = substream->private_data; (3) struct snd_soc_component *component = snd_soc_rtdcom_lookup(..); ... } It works today, but, will not work in the future if we support multi CPU/Codec/Platform, because 1 rtd might have multiple components which have same driver name. To solve this issue, each callback needs to be called with component. We already have many component driver callback. This patch copies each snd_pcm_ops member under component driver, and having "component" as parameter. --- ALSA SoC --- ... if (component->driver->open) => return component->driver->open(component, substream); ... --- driver --- => static int xxx_open(struct snd_soc_component *component, struct snd_pcm_substream *substream) { ... } *Note* Only Intel skl-pcm has .get_time_info implementation, but ALSA SoC framework doesn't call it so far. To keep its implementation, this patch keeps .get_time_info, but it is still not called. Intel guy need to support it in the future.

The snd_pcm_hw_constraint_minmax() works fine when a single codec is connected to a single CPU DAI, but in multicodec or DPCM setup the constraints placed by the driver will apply to the whole PCM stream (FE included) and thus prevents more than 8 playback channels for example.

For cases where an interface can be pin-muxed, we need to assess at probe time which configuration should be used. In cases such as SoundWire, we need to maintain an alternate list of machines and walk through them when the primary detection based on ACPI _HID fails.

When interfaces can be pin-muxed, static information from ACPI might not be enough. Add information on which links needs to be enabled by hardware/firmware for a specific machine driver to be selected. When walking through the list of possible machines, links will be checked, which implies that configurations where multiple links are required need to be checked first. Additional criteria will be needed later, such as which SoundWire Slave devices are actually enabled, but for now this helps detect between basic configurations.

According the documentation for snd_soc_update_bits the API will return a 1 if the update was successful with a value change, a 0 if the update was successful with no value change or a negative if the command just failed. So the value of return in the driver needs to be checked for being less then 0 or the caller may indicate failure when the value actually changed.

There are several problems in the error handling in fsl_mqs_probe(). 1) "ret" isn't initialized on some paths. GCC has a feature which warns about uninitialized variables but the code initializes "ret" to zero at the start of the function so the checking is turned off. 2) "gpr_np" is a pointer so initializing it to zero is confusing and generates a Sparse warning. 3) of_parse_phandle() doesn't return error pointers on error, it returns NULL. 4) If devm_snd_soc_register_component() fails then the function should free the "gpr_np".

This probe function is only called if the device is backed by a DT node, so switch this call to of_device_get_match_data() to reduce code size and simplify a bit. This also avoids needing to reference a potentially undefined variable because of_device_get_match_data() doesn't need to know anything beyond the struct device to find the match table.

It is easy to read code if it is cleanly using paired function/naming, like start <-> stop, register <-> unregister, etc, etc. But, current ALSA SoC code is very random, unbalance, not paired, etc. It is easy to create bug at the such code, and it will be difficult to debug. soc_cleanup_card_resources() (a) which is paired function of snd_soc_instantiate_card() (A) is calling soc_remove_dai_links() (*) to remove card related resources, but it is breaking add/remove balance (B)(b)(C)(c)(D)(d), in other words these should be called from soc_cleanup_card_resources() (a) from balance point of view. More headacke is that it is using original removing method for dai_link even though we already have snd_soc_remove_dai_link() which is the function for it (d). This patch removes snd_soc_remove_dai_links() and balance up code. static void soc_remove_dai_links(...) { ... (b) soc_remove_link_dais(card); (c) soc_remove_link_components(card); for_each_card_links_safe(card, link, _link) { ... /* it should use snd_soc_remove_dai_link() here */ (d) list_del(&link->list); } } (a) static int soc_cleanup_card_resources(...) { ... /* remove and free each DAI */ (*) soc_remove_dai_links(card); ... } (A) static int snd_soc_instantiate_card(struct snd_soc_card *card) { ... /* add predefined DAI links to the list */ for_each_card_prelinks(card, i, dai_link) (B) snd_soc_add_dai_link(card, dai_link); ... /* probe all components used by DAI links on this card */ (C) ret = soc_probe_link_components(card); ... /* probe all DAI links on this card */ (D) ret = soc_probe_link_dais(card); ... } Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Link: https://lore.kernel.org/r/875zl7bu1r.wl-kuninori.morimoto.gx@renesas.comSigned-off-by: Mark Brown <broonie@kernel.org>

Current rtd, rtd->dev, rtd->codec_dais are created by normal kzalloc(), but we want to use devm_kzalloc() as much as possible. Created rtd->dev is registered by device_register() at soc_new_pcm_runtime(), and it will be freed at soc_free_pcm_runtime() by device_unregister(). This means, if we can use devm_kzalloc(rtd->dev, xxx) for rtd / rtd->codec_dais, all these are automatically freed via soc_free_pcm_runtime(). This patch uses devm_kzalloc(rtd->dev, xxx) for rtd / rtd->codec_dais.

The Arndale boards come with different types of the audio daughter board. In order to support the WM1811 one we add new definition of an ASoC card which will be registered when the driver matches on "samsung,arndale-wm1811" compatible. There is no runtime detection of the audio daughter board type at the moment, compatible string of the audio card needs to be adjusted in DT, e.g. by the bootloader, depending on actual audio board (CODEC) used.

The host period bytes value needs to be passed to firmware. However current implementation uses this field for different purpose - to indicate whether FW should send stream position to the host. Therefore this patch introduces another field "no_stream_position", a boolean value aimed to store information about position tracking. This way host_period_bytes preserves its original value.

In a number of debug cases, the DMA-based trace can add problems (e.g. with HDaudio channel allocation). It also generates additional traffic on the bus and if the DMA handling is unreliable will prevent audio use-cases from working normally. Using the trace also requires tools to be installed on the target. The trace can be instead handled as dynamic debug. We can use a Kconfig to force the trace to be enabled in all cases, or use a module parameter to enable it on a need-basis, e.g. by setting "options snd_sof sof_debug=0x1" in a /etc/modprobe.d file.

The "snd_pcm_substream" handle was not initialized properly in hda-loader.c for firmware load. When the HDA DMAs were used to load the firmware, the interrupts related to firmware load also triggered calls to snd_sof_pcm_period_elapsed() on a non-existent ALSA PCM stream.

The old STOP sequence is: 1. stop DMA 2. send STOP ipc If delay happen before the steps 1 and 2, the DMA buffer will be empty in short time and cause pipeline xrun then stop the pipeline. Then the step 2 ipc stop will return error as pipeline is already stopped. Suggested change to avoid the issue is to switch the order of steps 1 and 2 for the stop sequence.
