| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add helper functions to allow drivers to specify several disjoint ranges for a variable. In particular, there is a codec (PCM512x) that has a hole in its supported range of rates, due to PLL and divider restrictions. This is like snd_pcm_hw_constraint_list(), but for ranges instead of points.

| * | | ALSA: pcm: Embed struct deviceTakashi Iwai2015-02-021-1/+1
| |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Like previous patches, at this time we embed the struct device into PCM object. However, this needs a bit more caution: struct snd_pcm doesn't own one device but two, for both playback and capture! Thus not struct snd_pcm but struct snd_pcm_str object contains the device. Along with this change, pcm->dev field is dropped for avoiding confusion. It was meant to point to a non-standard parent. But, since now we can touch each struct device directly, we can manipulate the parent field easily there, too.

* 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 bit of special care is necessary when creating the intersection of two rate masks. This comes from the special meaning of the SNDRV_PCM_RATE_CONTINUOUS and SNDRV_PCM_RATE_KNOT bits, which needs special handling when intersecting two rate masks. SNDRV_PCM_RATE_CONTINUOUS means the hardware supports all rates in a specific interval. SNDRV_PCM_RATE_KNOT means the hardware supports a set of discrete rates specified by a list constraint. For all other cases the supported rates are specified directly in the rate mask.

The two new types added by this patch describe streams that are capable of handling DSD samples in DOP format as 8-bit or in 16-bit (or at a x8 or x16 data rate, respectively). DSD itself specifies samples in *bit*, while DOP and ALSA handle them as *bytes*.

* ALSA: core: add hooks for audio timestampsPierre-Louis Bossart2012-10-231-0/+2
| | | | | | | | | | | | | | | | | | | ALSA did not provide any direct means to infer the audio time for A/V sync and system/audio time correlations (eg. PulseAudio). Applications had to track the number of samples read/written and add/subtract the number of samples queued in the ring buffer. This accounting led to small errors, typically several samples, due to the two-step process. Computing the audio time in the kernel is more direct, as all the information is available in the same routines. Also add new .audio_wallclock routine to enable fine-grain synchronization between monotonic system time and audio hardware time. Using the wallclock, if supported in hardware, allows for a much better sub-microsecond precision and a common drift tracking for all devices sharing the same wall clock (master clock).

This is generally useful as the Compress API uses the rate bit directly and it helps to be able to map back to the actual sample rate.

| * ALSA: PCM - Add PCM creation API for internal PCMs.Liam Girdwood2012-02-091-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The new ASoC dynamic PCM core needs to create PCMs and substreams that are for use by internal ASoC drivers only and not visible to userspace for direct IO. These new PCMs are similar to regular PCMs expect they have no device nodes or procfs entries. The ASoC component drivers use them in exactly the same way as regular PCMs for PCM and DAI operations. The intention is that a dynamic PCM based driver will register both regular PCMs and internal PCMs. The regular PCMs will be used for all IO with userspace however the internal PCMs will be used by the driver to route digital audio through numerous back end DAI links (with potentially a DSP providing different hw_params, DAI formats based on the regular front end PCM params) to devices like CODECs, MODEMs, Bluetooth, FM, DMICs, etc This patch adds a new snd_pcm_new_internal() API call to create the internal PCM without device nodes or procfs. It also adds adds a new internal flag to snd_pcm. [fixed minor coding-style issues by tiwai] Signed-off-by: Liam Girdwood <lrg@ti.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
