* ASoC: pcm: fix error handling when try_module_get() fails.Ranjani Sridharan2019-04-101-3/+5

* ASoC: pcm: update module refcount if module_get_upon_open is setRanjani Sridharan2019-04-081-0/+8
| | | | | | | | | | | | | | | Setting the module_get_upon_open field for component driver prevents the module refcount from being incremented during component probe(). This could lead to the module being allowed to be unloaded when a pcm stream is open. So, if this field is set, the module's refcount should be incremented during pcm open to prevent module removal when the component is in use. And, the refcount should be decremented upon pcm close.

* ASoC: dpcm: skip missing substream while applying symmetryJerome Brunet2019-04-021-1/+6
| | | | | | | | | | | | | | | If for any reason, the backend does not have the requested substream (like capture on a playback only backend), the BE will be skipped in dpcm_be_dai_startup(). However, dpcm_apply_symmetry() does not skip those BE and will dereference the be_substream (NULL) pointer anyway. Like in dpcm_be_dai_startup(), just skip those BE.

| * | ALSA: pcm: Suspend streams globally via device type PM opsTakashi Iwai2019-01-151-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Until now we rely on each driver calling snd_pcm_suspend*() explicitly at its own PM handling. However, this can be done far more easily by setting the PM ops to each actual snd_pcm device object. This patch adds the device_type object for PCM stream and assigns to each PCM stream object. The type contains only the PM ops for system suspend; we don't need to deal with the resume in general. The suspend hook simply calls snd_pcm_suspend_all() for the given PCM streams. This implies that the PM order is correctly put, i.e. PCM is suspended before the main (or codec) driver, which should be true in general. If a special ordering is needed, you'd need to adjust the device PM order manually later. This patch introduces a new flag, snd_pcm.no_device_suspend, too. With this flag set, the PCM device object won't invoke snd_pcm_suspend_all() by itself. This is needed for ASoC who wants to manage the PM call orders in its serialized way, and the flag is set in soc_new_pcm() as default. For the non-ASoC world, we can get rid of the manual snd_pcm_suspend calls. This will be done in the later patches.

* | | ASoC:soc-pcm:fix a codec fixup issue in TDM caseRander Wang2019-03-111-2/+5
| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On HDaudio platforms, if playback is started when capture is working, there is no audible output. This can be root-caused to the use of the rx|tx_mask to store an HDaudio stream tag. If capture is stared before playback, rx_mask would be non-zero on HDaudio platform, then the channel number of playback, which is in the same codec dai with the capture, would be changed by soc_pcm_codec_params_fixup based on the tx_mask at first, then overwritten by this function based on rx_mask at last. According to the author of tx|rx_mask, tx_mask is for playback and rx_mask is for capture. And stream direction is checked at all other references of tx|rx_mask in ASoC, so here should be an error. This patch checks stream direction for tx|rx_mask for fixup function. This issue would affect not only HDaudio+ASoC, but also I2S codecs if the channel number based on rx_mask is not equal to the one for tx_mask. It could be rarely reproduecd because most drivers in kernel set the same channel number to tx|rx_mask or rx_mask is zero. Tested on all platforms using stream_tag & HDaudio and intel I2S platforms.

* | ASoC: dapm: Only power up active channels from a DAICharles Keepax2019-02-021-0/+4
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* ASoC: dpcm: Properly initialise hw->rate_maxCharles Keepax2018-08-281-1/+1
| | | | | | | | | | | | | | | If the CPU DAI does not initialise rate_max, say if using using KNOT or CONTINUOUS, then the rate_max field will be initialised to 0. A value of zero in the rate_max field of the hardware runtime will cause the sound card to support no sample rates at all. Obviously this is not desired, just a different mechanism is being used to apply the constraints. As such update the setting of rate_max in dpcm_init_runtime_hw to be consistent with the non-DPCM cases and set rate_max to UINT_MAX if nothing is defined on the CPU DAI.

At the moment, if a BE link has more than one codec, and only one of these codecs has no capture DAI, it becomes impossible to start a capture stream because the merged format would be 0.

* | ASoC: core: Allow topology to override machine driver FE DAI link config.Liam Girdwood2018-07-031-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Machine drivers statically define a number of DAI links that currently cannot be changed or removed by topology. This means PCMs and platform components cannot be changed by topology at runtime AND machine drivers are tightly coupled to topology. This patch allows topology to override the machine driver DAI link config in order to reuse machine drivers with different topologies and platform components. The patch supports :- 1) create new FE PCMs with a topology defined PCM ID. 2) destroy existing static FE PCMs 3) change the platform component driver. 4) assign any new HW params fixups. 5) assign a new card name prefix to differentiate this topology to userspace. The patch requires no changes to the machine drivers, but does add some platform component flags that the platform component driver can assign before loading topologies.

Depending the order of the FEs within the rtd list, the result of the update might be different. For example: * Frontend A connected to backend C, with a 48kHz playback * Frontend B connected to backend D, with a 44.1kHz playback * FE A appears before FE B in the rtd list of the card. If we reparent BE C to FE B (disconnecting BE D): * old path update of FE A will run first, and BE C will get hw_free() and shutdown() * new path update of FE B will run after and BE C, which is stopped, so it will be configured at 44.1kHz, as expected If we reparent BE D to FE A (disconnecting BE C): * new path update of FE A will run first but since BE D is still running at 44.1kHz, it won't be reconfigured (no call to startup() or hw_params()) * old path update of FE B runs after, nothing happens * In this case, we end up with a BE playing at 44.1kHz a stream which is supposed to be played at 48Khz (too slow) To improve this situation, this patch performs all the FE old paths update before going on to update the new paths. With this, the result should no longer depend on the order of the FE within the card rtd list. Please note that there might be a small performance penalty since dpcm_process_paths() is called twice per stream direction.

This means PCMs and platform components cannot be changed by topology at runtime AND machine drivers are tightly coupled to topology. This patch allows topology to override the machine driver DAI link config in order to reuse machine drivers with different topologies and platform components. The patch supports :- 1) create new FE PCMs with a topology defined PCM ID. 2) destroy existing static FE PCMs 3) change the platform component driver. 4) assign any new HW params fixups. The patch requires no changes to the machine drivers, but does add some platform component flags that the platform component driver can assign before loading topologies.

* ASoC: snd_soc_component_driver has pmdown_timeKuninori Morimoto2017-10-231-1/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Current snd_soc_runtime_ignore_pmdown_time() tallys all Codec and CPU's "ignore_pmdown_time". Now, CPU (= via compoent) ignore_pmdown_time is fixed as "true". Codec's one is copied from Codec driver. This means Codec side default is "false". Current all Codec driver will be replaced into Component, thus, we can use for_each_rtdcom() for this totalization. This patch adds new "pmdown_time" on Component driver. Its inverted value will be used for this "ignore" totalizaton. Of course all existing Component driver doesn't have its settings now, thus, all existing "pmdown_time" is "false". This means all Components will ignore pmdown time. This is current CPU behavior. To keep compatibility, snd_soc_runtime_ignore_pmdown_time() totalize Component's inverted "pmdown_time" (= total will be true) and Codec's "ignore_pmdown_time" (= depends on Codec driver settings). Because It is using AND operation, its result is based on Codec driver settings only. This means this operation can keep compatibility and doesn't have nonconformity. When we replace Codec to Component, the driver which has ".ignore_pmdown_time = true" will be just removed, and the driver which doesn't have it will have new ".pmdown_time = true".

* ASoC: snd_soc_component_driver has snd_pcm_opsKuninori Morimoto2017-10-231-14/+353
| | | | | | | | | | | | | | | | | Platform will be replaced into Component in the future. snd_soc_platform_driver has snd_pcm_ops, but snd_soc_component_driver doesn't have it. To prepare for replacing, this patch adds snd_pcm_ops on component driver. platform will be replaced into component, and its code will be removed. But during replacing, both platform and component process code exists. To keep compatibility, to avoid platform NULL access and to avoid platform/component duplicate operation during replacing process, this patch has such code. Some of this code will be removed when platform was removed. Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@kernel.org>

| | | | | | | | | | | | | In current ALSA SoC, Platform only has pcm_new/pcm_free feature, but it should be supported on Component level. This patch adds it. The v1 was added commit 99b04f4c4051f7 ("ASoC: add Component level pcm_new/pcm_free") but it called all "card" connected component's pcm_new/free, it was wrong.

* | ASoC: soc-pcm: check symmetry after hw_paramsjiada wang2017-09-201-5/+4
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | hw_params may be fixup by be_hw_params_fixup, calling soc_pcm_params_symmetry() before hw_params will have issue if there is hw_params changes in be_hw_params_fixup. For example, with following use case 1. a dai-link which is able to convert sample rate on BE side 2. set BE playback and capture sample rate to 44100Hz 3. play a 48000Hz audio stream with this dai-link 4. record from this dai-link with 44100Hz sample rate Got following error message when record starts [ 495.013527] be_link_ak4613: ASoC: unmatched rate symmetry: 48000 - 44100 [ 495.021729] be_link_ak4613: ASoC: hw_params BE failed -22 [ 495.028589] rsnd_link0: ASoC: hw_params BE failed -22 Because in soc_pcm_hw_params(), FE rate is still having value before it is fixup by be_hw_params_fixup(), when soc_pcm_params_symmetry() checks symmetry, thus soc_pcm_params_symmetry() complains about the unmatched rate between the active stream and the new stream tries to start. This patch moves soc_pcm_params_symmetry() after hw_params to resolve the above issue. Signed-off-by: Jiada Wang <jiada_wang@mentor.com> Signed-off-by: Mark Brown <broonie@kernel.org>
