* pcm: Remove home brew atomic operationsTakashi Iwai2016-07-112-171/+1
| | | | | | | | | | | | We've had a few home brew atomic operations in a couple of places in the PCM code. This was for supporting the concurrent accesses, but in practice, it couldn't cover the race properly by itself alone. Since we have a wider concurrency protection via mutex now, we can get rid of these atomic codes, which worsens the portability significantly. Signed-off-by: Takashi Iwai <tiwai@suse.de>
* pcm: Add thread-safety to PCM APITakashi Iwai2016-07-111-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Traditionally, many of ALSA library functions are supposed to be thread-unsafe, and applications are required to take care of thread safety by themselves. However, people never be careful enough, and almost all applications fail in this regard. This patch is an attempt to harden the thread safety in exported PCM functions in a simplistic way: just wrap some of exported functions with the pthread mutex of each PCM object. Not all API functions are wrapped by the mutex since it doesn't make sense. Instead, the patchset covers only the functions that may be likely called concurrently. The supposedly thread-safe API functions are marked in the document. For achieving the feature, two new fields are added snd_pcm_t when the option is enabled: thread_safe and lock. The former indicates that the plugin is thread-safe that doesn't need this workaround and the latter is the pthread mutex. Currently only hw plugin have thread_safe=1. So, the most of real-time sensitive apps won't be influenced by this patchset. Although the patch covers most of PCM ops, a few snd_pcm_fast_ops are left without the extra mutex locking: namely, the ones that may have blocking behavior, i.e. resume, drain, readi, writei, readn and writen. These are supposed to handle own locking in the callbacks. Also, if anyone wants to disable this new thread-safe API feature, it can be still turned off via --disable-thread-safety configure option.

* ctl: add an API to set dimension levels to element informationTakashi Sakamoto2016-06-301-0/+2
| | | | | | | | | | | | | | | | In a former commit, 'struct snd_ctl_elem_info' is used as a 'container' to transfer extra fields of element information for APIs to add an element set. The extra fields should be filled in advance of call of the APIs. Currently, dimension level is in the extra fields and no APIs to set it. This commit adds an API to set dimension level to the information structure. This API is expected to be used in advance of usage of APIs to add an element set, for nothing others. When the information structure is extended in future, then the similar APIs shall be added for the new feature.

* ctl: support extra information to user-defined element setTakashi Sakamoto2016-06-301-5/+5
| | | | | | | | | | | | | | In ALSA control feature, information of an element includes extra fields to type-specific parameters; i.e. dimension. The fields can be extended in future. Meanwhile, current APIs to add user-defined element set can not support such an extended fields. This may cause inconveniences in future. This commit supports the fields, by changing APIs for element set. Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp> Signed-off-by: Takashi Iwai <tiwai@suse.de>

* ctl: add functions to add an element setTakashi Sakamoto2016-06-161-0/+21
| | | | | | | | | | | | ALSA control core allows userspace applications to add an element set. However, in ALSA userspace library, there's no APIs enough to utilize the feature. The library has APIs just to add an element set with a single element. This commit adds functions to add an element set with several elements.

* conf: Add thread-safe global tree referenceTakashi Iwai2016-05-171-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Most of open functions in alsa-lib have the call pattern: snd_config_update(); return snd_xxx_open(x, snd_config, ...); This means that the toplevel config gets updated, and passed to a local open function. Although snd_config_update() itself has a pthread mutex to be thread safe, the whole procedure above isn't thread safe. Namely, the global snd_config tree may be deleted and recreated at any time while the open function is being processed. This may lead to a data corruption and crash of the program. For avoiding the corruption, this patch introduces a refcount to config tree object. A few new helper functions are introduced as well: - snd_config_update_ref() does update and take the refcount of the toplevel tree. The obtained config tree has to be freed via snd_config_unref() below. - snd_config_ref() and snd_config_unref() manage the refcount of the config object. The latter eventually deletes the object when all references are gone. Along with these additions, the caller of snd_config_update() and snd_config global tree in alsa-lib are replaced with the new helpers. Signed-off-by: Takashi Iwai <tiwai@suse.de>

* topology: ABI - Define types for vendor tuplesMengdong Lin2016-04-071-1/+41
| | | | | | | | | | | | | | | | | | | Tuples, a pair of token and value, can be used to define vendor specific data, for controls and widgets. This can avoid importing binary data blob from other files. Vendor specific tuple arrays will be embeded in the private data buffer of a control or widget object. To be backward compatible, union is used to define the tuple arrays in the existing private data ABI object 'struct snd_soc_tplg_private'. Vendors need to make sure the token values defined by the topology conf file match those defined by their driver. Now supported tuple types are uuid, string, bool, byte, short and word.

This patch extends support for the other TLV types so they can be easily added at a later stage.

Users must set a proper access flag for a control since it's used to decide if the TLV field is valid and if a TLV callback is needed. Removed the following fields from topology TLV struct: - size/count: type can decide the size. - numid: not needed to initialize TLV for kcontrol. - data: replaced by the type specific struct.
