| * | | | ALSA: pcm: Add xrun_injection proc entryTakashi Iwai2014-11-041-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a new proc entry for PCM substreams to inject an XRUN. When a PCM substream is running and any value is written to its xrun_injection proc file, the driver triggers XRUN. This is a useful feature for debugging XRUN and error handling code paths. Note that this entry is enabled only when CONFIG_SND_PCM_XRUN_DEBUG is set. Signed-off-by: Takashi Iwai <tiwai@suse.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the sequencer module binding is performed independently from the card module itself. The reason behind it is to keep the sequencer stuff optional and allow the system running without it (e.g. for using PCM or rawmidi only). This works in most cases, but a remaining problem is that the binding isn't done automatically when a new driver module is probed. Typically this becomes visible when a hotplug driver like usb audio is used. This patch tries to address this and other potential issues. First, the seq-binder (seq_device.c) tries to load a missing driver module at creating a new device object. This is done asynchronously in a workq for avoiding the deadlock (modprobe call in module init path). This action, however, should be enabled only when the sequencer stuff was already initialized, i.e. snd-seq module was already loaded. For that, a new function, snd_seq_autoload_init() is introduced here; this clears the blocking of autoloading, and also tries to load all pending driver modules.

* | | | ASoC: dpcm: Fix race between FE/BE updates and triggerTakashi Iwai2014-11-041-0/+2
|/ / / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | DPCM can update the FE/BE connection states totally asynchronously from the FE's PCM state. Most of FE/BE state changes are protected by mutex, so that they won't race, but there are still some actions that are uncovered. For example, suppose to switch a BE while a FE's stream is running. This would call soc_dpcm_runtime_update(), which sets FE's runtime_update flag, then sets up and starts BEs, and clears FE's runtime_update flag again. When a device emits XRUN during this operation, the PCM core triggers snd_pcm_stop(XRUN). Since the trigger action is an atomic ops, this isn't blocked by the mutex, thus it kicks off DPCM's trigger action. It eventually updates and clears FE's runtime_update flag while soc_dpcm_runtime_update() is running concurrently, and it results in confusion. Usually, for avoiding such a race, we take a lock. There is a PCM stream lock for that purpose. However, as already mentioned, the trigger action is atomic, and we can't take the lock for the whole soc_dpcm_runtime_update() or other operations that include the lengthy jobs like hw_params or prepare. This patch provides an alternative solution. This adds a way to defer the conflicting trigger callback to be executed at the end of FE/BE state changes. For doing it, two things are introduced: - Each runtime_update state change of FEs is protected via PCM stream lock. - The FE's trigger callback checks the runtime_update flag. If it's not set, the trigger action is executed there. If set, mark the pending trigger action and returns immediately. - At the exit of runtime_update state change, it checks whether the pending trigger is present. If yes, it executes the trigger action at this point.

This patch introduces a new suspend_bias_off flag, which when set by a driver will let the ASoC core automatically put the device's DAPM context at the SND_SOC_BIAS_OFF level during suspend. Once the device is resumed the DAPM context will go back to SND_SOC_BIAS_STANDBY (if the context is idle, otherwise to SND_SOC_BIAS_ON). This will allow us to remove a fair bit of duplicated code from the drivers. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Mark Brown <broonie@kernel.org>

This patch consolidates it at the component level. The resulting code is slightly larger due to all the boiler plate code setting up the indirection for the table based control and DAPM registration. Once all drivers have been update to no longer use the snd_soc_codec_driver and snd_soc_platform_driver specific fields for this the indirection can be removed again. This patch contains two noteworthy hacks that are only meant to be temporary to be able to update drivers and the core in separate incremental patches. The first hack is related to that some DPCM platforms expect that the DAPM widgets for the DAIs of a snd_soc_component are created in the DAPM context of the snd_soc_platform that has the same parent device. For handling this the steal_sibling_dai_widgets attribute is introduced. It gets set for snd_soc_platforms that register DAPM elements. When creating the DAI widgets for a component this flag is checked and if it is found on one of the siblings the component will not create any DAI widgets in its own DAPM context. If the attribute is set on a platform it will look for siblings components and create DAI widgets for them in its own context. The fix for this will be to update the offending drivers to only register a single component rather than two. The second hack deals with the fact that the ASoC card suspend and resume code still needs a list of CODECs that have been registered for the card. To handle this the generic probe and remove path have a check to see if the component is CODEC and if yes add/remove it to the card's CODEC list. While it is possible to clean up the suspend/resume code to not need the CODEC list anymore this is a bit of a chicken and egg problem since it will become easier to clean up the suspend/resume code once there is a unified component layer.

| | * | ASoC: Move debugfs registration to the component levelLars-Peter Clausen2014-08-191-5/+15
| | |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The debugfs registration is mostly identical between platforms and CODECs. This patches consolidates the two implementations at the component level. Unfortunately there are still a couple of CODEC specific debugfs files that are related to legacy ASoC IO that need to be registered. For this a new callback is added to the component struct that will be initialized when a CODEC is registered and will be used to register the CODEC specific files. Once there are no drivers left using legacy IO this can be removed again. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Mark Brown <broonie@linaro.org>

The audio format is either 32-bit raw or a 32-bit PCM format. To utilize this feature on linux this patch introduces a new 32-bit DSD sampleformat DSD_U32_LE. A follow up patch will add a quirk for XMOS based devices to utilize the new format. Further patches will add support to alsa-lib.

* | ALSA: pcm: Uninline snd_pcm_stream_lock() and _unlock()Takashi Iwai2014-09-031-69/+12
| | | | | | | | | | | | | | | | | | | | | | The previous commit for the non-atomic PCM ops added more codes to snd_pcm_stream_lock() and its variants. Since they are inlined functions, it resulted in a significant code size bloat. For reducing the size bloat, this patch changes the inline functions to the normal function calls. The export of rwlock and rwsem are removed as well, since they are referred only in pcm_native.c now. Signed-off-by: Takashi Iwai <tiwai@suse.de>
* | ALSA: pcm: Allow nonatomic trigger operationsTakashi Iwai2014-09-031-12/+46
|/ | | | | | | | | | | | | | | | | | | | | | | | | | Currently, many PCM operations are performed in a critical section protected by spinlock, typically the trigger and pointer callbacks are assumed to be atomic. This is basically because some trigger action (e.g. PCM stop after drain or xrun) is done in the interrupt handler. If a driver runs in a threaded irq, however, this doesn't have to be atomic. And many devices want to handle trigger in a non-atomic context due to lengthy communications. This patch tries all PCM calls operational in non-atomic context. What it does is very simple: replaces the substream spinlock with the corresponding substream mutex when pcm->nonatomic flag is set. The driver that wants to use the non-atomic PCM ops just needs to set the flag and keep the rest as is. (Of course, it must not handle any PCM ops in irq context.) Note that the code doesn't check whether it's atomic-safe or not, but trust in 100% that the driver sets pcm->nonatomic correctly. One possible problem is the case where linked PCM substreams have inconsistent nonatomic states. For avoiding this, snd_pcm_link() returns an error if one tries to link an inconsistent PCM substream.

A big thanks to Benoit and Misael for their work on this. Otherwise it's been a fairly standard release for development, including more componentisation work from Lars-Peter and a good selection of both CODEC and CPU drivers. - Support for multiple CODECs attached to a single DAI, enabling systems with for example multiple DAC/speaker drivers on a single link, contributed by Benoit Cousson based on work from Misael Lopez Cruz. - Support for byte controls larger than 256 bytes based on the use of TLVs contributed by Omair Mohammed Abdullah. - More componentisation work from Lars-Peter Clausen. - The remainder of the conversions of CODEC drivers to params_width() - Drivers for Cirrus Logic CS4265, Freescale i.MX ASRC blocks, Realtek RT286 and RT5670, Rockchip RK3xxx I2S controllers and Texas Instruments TAS2552. - Lots of updates and fixes, especially to the DaVinci, Intel, Freescale, Realtek, and rcar drivers.

So we should make sure the MCLK is enabled before this resume(). Previously we let the machine driver get the clock and enable it in its probe(). However, considering about power saving, it'll be better to enable it when it's going to be used and disable it after using. So this patch just simply adds clk_get() and clk_enable() to WM8962 driver. Meanwhile, it marks clock pointer to NULL if no clock assigned to it so it will not break any current function.
