2022-03-11ASoC: Export DAI register and widget ctor and dctor functionsCezary Rojewski1-0/+1
To allow for more flexibility i.e. populating component DAIs dynamically during its initialization, without being limited to topology loading procedure, expose snd_soc_register(), snd_soc_dapm_new_dai_widgets() and snd_soc_dapm_free_widget() functions. Allows users to first check available resources e.g. number of PCMs supported by HDAudio codec before allocating the number of DAPM widgets needed. This prevents superfluous objects from being created or allows driver to adjust to situation when resources are limited.

2020-05-08ASoC: soc-core: Replace zero-length array with flexible-arrayGustavo A. R. Silva1-1/+1
The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] sizeof(flexible-array-member) triggers a warning because flexible array members have incomplete type[1]. There are some instances of code in which the sizeof operator is being incorrectly/erroneously applied to zero-length arrays and the result is zero. Such instances may be hiding some bugs. So, this work (flexible-array member conversions) will also help to get completely rid of those sorts of issues. This issue was found with the help of Coccinelle.

2020-02-25ASoC: soc-pcm: move dpcm_path_put() to soc-pcm.cKuninori Morimoto1-0/+1
dpcm_path_put() (A) is calling kfree(*list). The freed list is created by dapm_widget_list_create() (B) which is called from snd_soc_dapm_dai_get_connected_widgets() (C) which is called from dpcm_path_get() (D). (B) dapm_widget_list_create(**list, ...) { ... => *list = kzalloc(); ... } (C) snd_soc_dapm_dai_get_connected_widgets(..., **list, ...) { ... dapm_widget_list_create(list, ...); ... } (D) dpcm_path_get(..., **list) { ... snd_soc_dapm_dai_get_connected_widgets(..., list, ...); ... } (A) dpcm_path_put(**list) { => kfree(*list); } This kind of unbalance code is very difficult to read/understand. To avoid this issue, this patch adds each missing paired function dapm_widget_list_free() for dapm_widget_list_create() (B), and snd_soc_dapm_dai_free_widgets() for snd_soc_dapm_dai_get_connected_widgets() (C). This patch uses these, and moves dpcm_path_put() next to dpcm_path_get().

2019-02-02ASoC: dapm: Only power up active channels from a DAICharles Keepax1-8/+14
Currently all widgets attached to a DAI link will be powered up when the DAI is active, however this may include routes that are not actually in use if there are unused channels available on the DAI. The macros for creating AIF widgets already include an entry for slot, it is proposed to change that to channel. The effective difference here being respresenting the logical channel index rather than the physical slot index. The CODECs currently using the slot entry on the DAPM_AIF macros are using it in a manner consistent with this, the CODECs not using it just have the field set to zero. A variable is added to snd_soc_dapm_widget to represent this channel index and then for each AIF widget attached to a DAI this is compared against the number of channels on the stream. Enabling the links for those which will be in use. This has the nice property that the CODECs which haven't used the slot/channel entry in the macro will function exactly as before due to all the AIF widgets having a channel of zero and a stream by definition having at least one channel.

Certain situations may warrant examining DAPM paths only to a certain arbitrary point, as opposed to always following them to the end. For instance, when establishing a connection between a front-end DAI link and a back-end DAI link in a DPCM path, it does not make sense to walk the DAPM graph beyond the first widget associated with a back-end link. This patch introduces a mechanism which lets a user of dai_get_connected_widgets supply a function which will be called for every node during the graph walk. When invoked, this function can execute arbitrary logic to decide whether the walk, given a DAPM widget and walk direction, should be terminated at that point or continued as normal.

2015-08-13ASoC: dapm: Consolidate input and output path handlingLars-Peter Clausen1-14/+55
After the recent cleanups and generalizations of the DAPM algorithm the handling of input and output paths is now fully symmetric. This means by making some slight changes to the data structure and using arrays with one entry for each direction, rather than separate fields, it is possible to create a generic implementation that is capable of handling both input and output paths. Unfortunately this generalization significantly increases the code size on the hot path of is_connected_{input,output}_ep() and dapm_widget_invalidate_{input,output}_paths(), which has a negative impact on the overall performance. The inner loops of those functions are quite small and the generic implementation adds extra pointer arithmetic in a few places. Testing on ARM shows that the combined code size of the specialized functions is about 50% larger than the generalized function in relative numbers. But in absolute numbers its less than 200 bytes, which is still quite small. On the other hand the generalized function increases the execution time of dapm_power_one_widget() by 30%. Given that this function is one of the most often called functions of the DAPM framework the trade-off of getting better performance at expense of generating slightly larger code at seems to be worth it. To avoid this still keep two versions of these functions around, one for input and one for output. But have a generic implementation of the algorithm which gets inlined by those two versions. And then let the compiler take care of optimizing it and removing he extra instructions. This still reduces the source code size as well as the makes making changes to the implementation more straight forward since the same change does no longer need to be done in two separate places. Also on the slow paths we can use a generic implementations that handle both input and output paths. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Mark Brown <broonie@kernel.org>

The file format is simple and divided into blocks for each object type and each block has a header that defines it's size and type. Blocks can be in any order of type and can either all be in a single file or spread across more than one file. Blocks also have a group identifier ID so that they can be loaded and unloaded by ID.

2015-05-12ASoC: dapm: Add cache to speed up adding of routesCharles Keepax1-0/+7
Some CODECs have a significant number of DAPM routes and for each route, when it is added to the card, the entire card widget list must be searched. When adding routes it is very likely, however, that adjacent routes will require adjacent widgets. For example all the routes for a mux are likely added in a block and the sink widget will be the same each time and it is also quite likely that the source widgets are sequential located in the widget list. This patch adds a cache to the DAPM context, this cache will hold the source and sink widgets from the last call to snd_soc_dapm_add_route for that context. A small search of the widget list will be made from those points for both the sink and source. Currently this search only checks both the last widget and the one adjacent to it. On wm8280 which has approximately 500 widgets and 30000 routes (one of the largest CODECs in mainline), the number of paths that hit the cache is 24000, which significantly improves probe time.

2015-05-06ASoC: dapm: Add demux supportLars-Peter Clausen1-0/+5
A demux is conceptually similar to a mux. Where a mux has multiple input and one output and selects one of the inputs to be connected to the output, the demux has one input and multiple outputs and selects one of the outputs to which the input gets connected. This similarity makes it straight forward to support them in DAPM using the existing mux support, we only need to swap sinks and sources when initially setting up the paths. The only slightly tricky part is that there can only be one control per path. Since mixers/muxes are at the sink of a path and a demux is at the source and both types want a control it is not possible to directly connect a demux output to a mixer/mux input. The patch adds some sanity checks to make sure that this does not happen. Drivers who want to model hardware which directly connects a demux output to a mixer/mux input can do this by inserting a dummy widget between the two. E.g.: { "Dummy", "Demux Control", "Demux" }, { "Mixer", "Mixer Control", "Dummy" }, Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Mark Brown <broonie@kernel.org>

2015-04-27ASoC: Add helper functions bias level managementLars-Peter Clausen1-0/+34
Currently drivers are responsible for managing the bias_level field of their DAPM context. The DAPM state itself is managed by the DAPM core though and the core has certain expectations on how and when the bias_level field should be updated. If drivers don't adhere to these undefined behavior can occur. This patch adds a few helper functions for manipulating the DAPM context state, each function with a description on when it should be used and what its effects are. This will also help us to move more of the bias_level management from drivers to the DAPM core. For convenience also add snd_soc_codec_* wrappers around these helpers.
