8 Tracepoints in ALSA PCM core
11 ALSA PCM core registers ``snd_pcm`` subsystem to kernel tracepoint system.
19 ------------------------------------

30 In a design of ALSA PCM core, data transmission is abstracted as PCM substream.
34 interaction between applications and ALSA PCM core. Once decided, runtime of
46 Configurable. ALSA PCM core and some drivers handle this flag to select
53 - SNDRV_PCM_HW_PARAM_ACCESS
54 - SNDRV_PCM_HW_PARAM_FORMAT
55 - SNDRV_PCM_HW_PARAM_SUBFORMAT
61 - SNDRV_PCM_HW_PARAM_SAMPLE_BITS
62 - SNDRV_PCM_HW_PARAM_FRAME_BITS
63 - SNDRV_PCM_HW_PARAM_CHANNELS

70 - SNDRV_PCM_HW_PARAM_BUFFER_SIZE
71 - SNDRV_PCM_HW_PARAM_BUFFER_BYTES
72 - SNDRV_PCM_HW_PARAM_TICK_TIME
76 mask/interval parameter can be changed by ALSA PCM core. For
80 Read-only. After returning from ioctl(2), buffer in user space for
84 Read-only. This represents hardware/driver capabilities as bit flags
90 Read-only. This value represents available bit width in MSB side of
96 Read-only. This value represents numerator of sampling rate in fraction
98 decided as a single value, this value is also calculated according to
102 Read-only. This value represents denominator of sampling rate in
104 SNDRV_PCM_HW_PARAM_RATE was decided as a single value, this value is
108 Read-only. This value represents the size of FIFO in serial sound
113 ALSA PCM core handles buffer of struct snd_pcm_hw_params when
120 to compute the target parameter. ALSA PCM core registers some rules to the
138 mask/interval parameters. When ALSA PCM core changes them, ``hw_mask_param`` or
141 ALSA PCM core also has a pretty print format for each of the tracepoints. Below
157 field for rules of constraint consists of two sub-fields; index of applied rule
159 means that the parameter is changed by ALSA PCM core, regardless of the rules.
