ALSA: pcm: Constify the list in snd_pcm_hw_constraint_list

2012-03-15T06:35:17+00:00

Allows the constraint lists to be declared const by drivers which seems
reasonable; there's plenty of other constification we could do if we were
being complete but this was easy and quick.

ALSA: PCM - Add PCM creation API for internal PCMs.

2012-02-09T08:20:22+00:00

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.

ALSA: pcm - Export snd_pcm_lib_default_mmap() helper

2011-09-28T15:15:14+00:00

Export the default mmap function, snd_pcm_lib_default_mmap().
The upcoming non-snooping support in HD-audio driver will use this
to override the mmap method.

Add a helper function to allow drivers to disable hardware resampling
when the application has specified the SNDRV_PCM_HW_PARAMS_NORESAMPLE
flag.

PM QoS: Minor clean-ups

2011-08-25T13:35:12+00:00

 - Misc fixes to improve code readability:
  * rename struct pm_qos_request_list to struct pm_qos_request,
  * rename pm_qos_req parameter to req in internal code,
    consistenly use req in the API parameters,
  * update the in-kernel API callers to the new parameters names,
  * rename of fields names (requests, list, node, constraints)

PM QoS: Move and rename the implementation files

2011-08-25T13:35:03+00:00

The PM QoS implementation files are better named
kernel/power/qos.c and include/linux/pm_qos.h.

The PM QoS support is compiled under the CONFIG_PM option.

ALSA: Make pcm.h self-contained

2011-07-26T15:21:24+00:00

Move the macros depending on snd_mask_min() and co out of pcm.h into
pcm_params.h.  Otherwise using some params_*() macros will give comiple
errors without inclusion of pcm_params.h.

Also use hw_param_interval_c() and hw_param_mask_c() for const pointer.
