ALSA声卡驱动的DAPM（一）-DPAM详解

最近使用tinymix 调试相应的音频通道，但是一直不知道音频通道的原理是什么。所以百度了一下，百度结果是与DPAM有关。

一、DAPM简介：

DAPM是Dynamic Audio Power Management的缩写，直译过来就是动态音频电源管理的意思，DAPM是为了使基于linux的移动设备上的音频子系统，在任何时候都工作在最小功耗状态下。DAPM对用户空间的应用程序来说是透明的，所有与电源相关的开关都在ASoc core中完成。用户空间的应用程序无需对代码做出修改，也无需重新编译，DAPM根据当前激活的音频流（playback/capture）和声卡中的mixer等的配置来决定那些音频控件的电源开关被打开或关闭。

DAPM是基于kcontrol改进过后的相应框架，增加了相应的电源管理机制，其电源管理机制其实就是按照相应的音频路径，完美的对各种部件的电源进行控制，而且按照某种顺序进行。

kcontrol是什么？

二、DAPM的基本单位widget：

widget把kcontrol和动态电源管理进行了有机的结合，同时还具备音频路径的连结功能，一个widget可以与它相邻的widget有某种动态的连结关系。在DAPM框架中，widget用结构体snd_soc_dapm_widget来描述：

 1 struct snd_soc_dapm_widget {  
 2         enum snd_soc_dapm_type id;  　　//该widget的类型值，比如snd_soc_dapm_output，snd_soc_dapm_mixer等等。
 3         const char *name;               /* widget name */  
 4   
 5         ......  
 6         /* dapm control */  
 7         int reg;                                /* negative reg = no direct dapm */  
 8         unsigned char shift;                    /* bits to shift */  
 9         unsigned int value;                             /* widget current value */  
10         unsigned int mask;                      /* non-shifted mask */  
11         ......  
12   
13         int (*power_check)(struct snd_soc_dapm_widget *w);  
14   
15         int (*event)(struct snd_soc_dapm_widget*, struct snd_kcontrol *, int);  
16   
17         /* kcontrols that relate to this widget */  
18         int num_kcontrols;  
19         const struct snd_kcontrol_new *kcontrol_news;  
20         struct snd_kcontrol **kcontrols;  
21   
22         /* widget input and outputs */  
23         struct list_head sources;  
24         struct list_head sinks;  
25         ......  
26 };

2.1 widget的种类:

在DAPM框架中，把各种不同的widget划分为不同的种类，snd_soc_dapm_widget结构中的id字段用来表示该widget的种类，可选的种类都定义在一个枚举中：

1 enum snd_soc_dapm_type {......}

下面我们逐个解释一下这些widget的种类：

 1 snd_soc_dapm_input     该widget对应一个输入引脚。
 2 snd_soc_dapm_output    该widget对应一个输出引脚。
 3 snd_soc_dapm_mux    该widget对应一个mux控件。
 4 snd_soc_dapm_virt_mux    该widget对应一个虚拟的mux控件。
 5 snd_soc_dapm_value_mux    该widget对应一个value类型的mux控件。
 6 snd_soc_dapm_mixer    该widget对应一个mixer控件。
 7 snd_soc_dapm_mixer_named_ctl    该widget对应一个mixer控件，但是对应的kcontrol的名字不会加入widget的名字作为前缀。
 8 snd_soc_dapm_pga    该widget对应一个pga控件（可编程增益控件）。
 9 snd_soc_dapm_out_drv    该widget对应一个输出驱动控件
10 snd_soc_dapm_adc    该widget对应一个ADC 
11 snd_soc_dapm_dac    该widget对应一个DAC 
12 snd_soc_dapm_micbias    该widget对应一个麦克风偏置电压控件
13 snd_soc_dapm_mic    该widget对应一个麦克风。
14 snd_soc_dapm_hp    该widget对应一个耳机。
15 snd_soc_dapm_spk    该widget对应一个扬声器。
16 snd_soc_dapm_line     该widget对应一个线路输入。
17 snd_soc_dapm_switch       该widget对应一个模拟开关。
18 snd_soc_dapm_vmid      该widget对应一个codec的vmid偏置电压。
19 snd_soc_dapm_pre      machine级别的专用widget，会先于其它widget执行检查操作。
20 snd_soc_dapm_post    machine级别的专用widget，会后于其它widget执行检查操作。
21 snd_soc_dapm_supply           对应一个电源或是时钟源。
22 snd_soc_dapm_regulator_supply  对应一个外部regulator稳压器。
23 snd_soc_dapm_clock_supply      对应一个外部时钟源。
24 snd_soc_dapm_aif_in            对应一个数字音频输入接口，比如I2S接口的输入端。
25 snd_soc_dapm_aif_out          对应一个数字音频输出接口，比如I2S接口的输出端。
26 snd_soc_dapm_siggen            对应一个信号发生器。
27 snd_soc_dapm_dai_in           对应一个platform或codec域的输入DAI结构。
28 snd_soc_dapm_dai_out        对应一个platform或codec域的输出DAI结构。
29 snd_soc_dapm_dai_link         用于链接一对输入/输出DAI结构。

2.2 widget之间的连接器path：

DAPM为我们提出了path这一概念，path相当于电路中的一根跳线，它把一个widget的输出端和另一个widget的输入端连接在一起，path用snd_soc_dapm_path结构来描述：

 1 /* dapm audio path between two widgets */
 2 struct snd_soc_dapm_path {
 3     const char *name;
 4     const char *long_name;
 5 
 6     /* source (input) and sink (output) widgets */
 7     struct snd_soc_dapm_widget *source;
 8     struct snd_soc_dapm_widget *sink;
 9     struct snd_kcontrol *kcontrol;
10 
11     /* status */
12     u32 connect:1;    /* source and sink widgets are connected */
13     u32 walked:1;    /* path has been walked */
14     u32 walking:1;  /* path is in the process of being walked */
15     u32 weak:1;    /* path ignored for power management */
16 
17     int (*connected)(struct snd_soc_dapm_widget *source,
18              struct snd_soc_dapm_widget *sink);
19 
20     struct list_head list_source;
21     struct list_head list_sink;
22     struct list_head list;
23 };

path与widget的关系如下图：

2.3 widget的连接关系route：

1 struct snd_soc_dapm_route {  
2         const char *sink;  
3         const char *control;  
4         const char *source;  
5         int (*connected)(struct snd_soc_dapm_widget *source,  
6                          struct snd_soc_dapm_widget *sink);  
7 };

sink指向到达端widget的名字字符串，source指向起始端widget的名字字符串，control指向负责控制该连接所对应的kcontrol名字字符串，connected回调则定义了上一节所提到的自定义连接检查回调函数。该结构的意义很明显就是：source通过一个kcontrol，和sink连接在一起，现在是否处于连接状态，请调用connected回调函数检查。

2.4 如何定义各种widget：

和普通的kcontrol一样，DAPM框架为我们提供了大量的辅助宏用来定义各种各样的widget控件，这些宏定义根据widget的类型，按照它们的电源所在的域，被分为了几个域，他们分别是：

codec域比如VREF和VMID等提供参考电压的widget，这些widget通常在codec的probe/remove回调中进行控制，当然，在工作中如果没有音频流时，也可以适当地进行控制它们的开启与关闭。
platform域位于该域上的widget通常是针对平台或板子的一些需要物理连接的输入/输出接口，例如耳机、扬声器、麦克风，因为这些接口在每块板子上都可能不一样，所以通常它们是在machine驱动中进行定义和控制，并且也可以由用户空间的应用程序通过某种方式来控制它们的打开和关闭。
音频路径域一般是指codec内部的mixer、mux等控制音频路径的widget，这些widget可以根据用户空间的设定连接关系，自动设定他们的电源状态。
音频数据流域是指那些需要处理音频数据流的widget，例如ADC、DAC等等。

codec域widget的定义

目前，DAPM框架只提供了定义一个codec域widget的辅助宏：

1 #define SND_SOC_DAPM_VMID(wname)   
2 {       .id = snd_soc_dapm_vmid, .name = wname, .kcontrol_news = NULL,   
3         .num_kcontrols = 0}

platform域widget的定义

DAPM框架为我们提供了多种platform域widget的辅助定义宏：

 1 #define SND_SOC_DAPM_SIGGEN(wname)   
 2 {       .id = snd_soc_dapm_siggen, .name = wname, .kcontrol_news = NULL,   
 3         .num_kcontrols = 0, .reg = SND_SOC_NOPM }  
 4 #define SND_SOC_DAPM_INPUT(wname)   
 5 {       .id = snd_soc_dapm_input, .name = wname, .kcontrol_news = NULL,   
 6         .num_kcontrols = 0, .reg = SND_SOC_NOPM }  
 7 #define SND_SOC_DAPM_OUTPUT(wname)   
 8 {       .id = snd_soc_dapm_output, .name = wname, .kcontrol_news = NULL,   
 9         .num_kcontrols = 0, .reg = SND_SOC_NOPM }  
10 #define SND_SOC_DAPM_MIC(wname, wevent)   
11 {       .id = snd_soc_dapm_mic, .name = wname, .kcontrol_news = NULL,   
12         .num_kcontrols = 0, .reg = SND_SOC_NOPM, .event = wevent,   
13         .event_flags = SND_SOC_DAPM_PRE_PMU | SND_SOC_DAPM_POST_PMD}  
14 #define SND_SOC_DAPM_HP(wname, wevent)   
15 {       .id = snd_soc_dapm_hp, .name = wname, .kcontrol_news = NULL,   
16         .num_kcontrols = 0, .reg = SND_SOC_NOPM, .event = wevent,   
17         .event_flags = SND_SOC_DAPM_POST_PMU | SND_SOC_DAPM_PRE_PMD}  
18 #define SND_SOC_DAPM_SPK(wname, wevent)   
19 {       .id = snd_soc_dapm_spk, .name = wname, .kcontrol_news = NULL,   
20         .num_kcontrols = 0, .reg = SND_SOC_NOPM, .event = wevent,   
21         .event_flags = SND_SOC_DAPM_POST_PMU | SND_SOC_DAPM_PRE_PMD}  
22 #define SND_SOC_DAPM_LINE(wname, wevent)   
23 {       .id = snd_soc_dapm_line, .name = wname, .kcontrol_news = NULL,   
24         .num_kcontrols = 0, .reg = SND_SOC_NOPM, .event = wevent,   
25         .event_flags = SND_SOC_DAPM_POST_PMU | SND_SOC_DAPM_PRE_PMD}

音频路径（path）域widget的定义

这种widget通常是对普通kcontrols控件的再封装，增加音频路径和电源管理功能，所以这种widget会包含一个或多个kcontrol。

 1 #define SND_SOC_DAPM_PGA(wname, wreg, wshift, winvert,  
 2          wcontrols, wncontrols)   
 3 {       .id = snd_soc_dapm_pga, .name = wname, .reg = wreg, .shift = wshift,

 5 #define SND_SOC_DAPM_OUT_DRV(wname, wreg, wshift, winvert,  
 6          wcontrols, wncontrols)   
 7 {       .id = snd_soc_dapm_out_drv, .name = wname, .reg = wreg, .shift = wshift,   
 8         .invert = winvert, .kcontrol_news = wcontrols, .num_kcontrols = wncontrols}

14          wcontrols, wncontrols)  
15 {       .id = snd_soc_dapm_mixer_named_ctl, .name = wname, .reg = wreg,   
16         .shift = wshift, .invert = winvert, .kcontrol_news = wcontrols,   
17         .num_kcontrols = wncontrols}  
18 #define SND_SOC_DAPM_MICBIAS(wname, wreg, wshift, winvert)   
19 {       .id = snd_soc_dapm_micbias, .name = wname, .reg = wreg, .shift = wshift,   
20         .invert = winvert, .kcontrol_news = NULL, .num_kcontrols = 0}  
21 #define SND_SOC_DAPM_SWITCH(wname, wreg, wshift, winvert, wcontrols)   
22 {       .id = snd_soc_dapm_switch, .name = wname, .reg = wreg, .shift = wshift,   
23         .invert = winvert, .kcontrol_news = wcontrols, .num_kcontrols = 1}  
24 #define SND_SOC_DAPM_MUX(wname, wreg, wshift, winvert, wcontrols)   
25 {       .id = snd_soc_dapm_mux, .name = wname, .reg = wreg, .shift = wshift,   
26         .invert = winvert, .kcontrol_news = wcontrols, .num_kcontrols = 1}  
27 #define SND_SOC_DAPM_VIRT_MUX(wname, wreg, wshift, winvert, wcontrols)   
28 {       .id = snd_soc_dapm_virt_mux, .name = wname, .reg = wreg, .shift = wshift,   
29         .invert = winvert, .kcontrol_news = wcontrols, .num_kcontrols = 1}  
30 #define SND_SOC_DAPM_VALUE_MUX(wname, wreg, wshift, winvert, wcontrols)   
31 {       .id = snd_soc_dapm_value_mux, .name = wname, .reg = wreg,   
32         .shift = wshift, .invert = winvert, .kcontrol_news = wcontrols,   
33         .num_kcontrols = 1}

音频数据流（stream）域widget的定义

这些widget主要包含音频输入/输出接口，ADC/DAC等等：

 1 #define SND_SOC_DAPM_AIF_IN(wname, stname, wslot, wreg, wshift, winvert) 
 2 {       .id = snd_soc_dapm_aif_in, .name = wname, .sname = stname, 
 3         .reg = wreg, .shift = wshift, .invert = winvert }
 4 #define SND_SOC_DAPM_AIF_IN_E(wname, stname, wslot, wreg, wshift, winvert, 
 5                               wevent, wflags)                           
 6 {       .id = snd_soc_dapm_aif_in, .name = wname, .sname = stname, 
 7         .reg = wreg, .shift = wshift, .invert = winvert, 
 8         .event = wevent, .event_flags = wflags }
 9 #define SND_SOC_DAPM_AIF_OUT(wname, stname, wslot, wreg, wshift, winvert) 
10 {       .id = snd_soc_dapm_aif_out, .name = wname, .sname = stname, 
11         .reg = wreg, .shift = wshift, .invert = winvert }
12 #define SND_SOC_DAPM_AIF_OUT_E(wname, stname, wslot, wreg, wshift, winvert, 
13                              wevent, wflags)                            
14 {       .id = snd_soc_dapm_aif_out, .name = wname, .sname = stname, 
15         .reg = wreg, .shift = wshift, .invert = winvert, 
16         .event = wevent, .event_flags = wflags }
17 #define SND_SOC_DAPM_DAC(wname, stname, wreg, wshift, winvert) 
18 {       .id = snd_soc_dapm_dac, .name = wname, .sname = stname, .reg = wreg, 
19         .shift = wshift, .invert = winvert}
20 #define SND_SOC_DAPM_DAC_E(wname, stname, wreg, wshift, winvert, 
21                            wevent, wflags)                              
22 {       .id = snd_soc_dapm_dac, .name = wname, .sname = stname, .reg = wreg, 
23         .shift = wshift, .invert = winvert, 
24         .event = wevent, .event_flags = wflags}

26 {       .id = snd_soc_dapm_adc, .name = wname, .sname = stname, .reg = wreg, 
27         .shift = wshift, .invert = winvert}
28 #define SND_SOC_DAPM_ADC_E(wname, stname, wreg, wshift, winvert, 
29                            wevent, wflags)                              
30 {       .id = snd_soc_dapm_adc, .name = wname, .sname = stname, .reg = wreg, 
31         .shift = wshift, .invert = winvert, 
32         .event = wevent, .event_flags = wflags}
33 #define SND_SOC_DAPM_CLOCK_SUPPLY(wname) 
34 {       .id = snd_soc_dapm_clock_supply, .name = wname, 
35         .reg = SND_SOC_NOPM, .event = dapm_clock_event, 
36         .event_flags = SND_SOC_DAPM_PRE_PMU | SND_SOC_DAPM_POST_PMD }

2.5 dapm kcontrol：

dapm kcontrol是widget的开关，info函数是显示widget的函数，put是设置，get是获取；

三、建立widget和route：

以我们打开音频tinymix ‘PRI_MI2S_RX Audio Mixer MultiMedia1’ 1 为例子来了解整个过程：

3.1 利用辅助宏定义widget所需要的dapm kcontrol：

 1 static const struct snd_kcontrol_new primary_mi2s_rx_mixer_controls[] = {
 2     SOC_SINGLE_EXT("MultiMedia1", MSM_BACKEND_DAI_PRI_MI2S_RX ,
 3     MSM_FRONTEND_DAI_MULTIMEDIA1, 1, 0, msm_routing_get_audio_mixer,
 4     msm_routing_put_audio_mixer),
 5     SOC_SINGLE_EXT("MultiMedia2", MSM_BACKEND_DAI_PRI_MI2S_RX,
 6     MSM_FRONTEND_DAI_MULTIMEDIA2, 1, 0, msm_routing_get_audio_mixer,
 7     msm_routing_put_audio_mixer),
 8     SOC_SINGLE_EXT("MultiMedia3", MSM_BACKEND_DAI_PRI_MI2S_RX,
 9     MSM_FRONTEND_DAI_MULTIMEDIA3, 1, 0, msm_routing_get_audio_mixer,
10     msm_routing_put_audio_mixer),
11     SOC_SINGLE_EXT("MultiMedia4", MSM_BACKEND_DAI_PRI_MI2S_RX,
12     MSM_FRONTEND_DAI_MULTIMEDIA4, 1, 0, msm_routing_get_audio_mixer,
13     msm_routing_put_audio_mixer),
14     SOC_SINGLE_EXT("MultiMedia5", MSM_BACKEND_DAI_PRI_MI2S_RX,
15     MSM_FRONTEND_DAI_MULTIMEDIA5, 1, 0, msm_routing_get_audio_mixer,
16     msm_routing_put_audio_mixer),
17     SOC_SINGLE_EXT("MultiMedia6", MSM_BACKEND_DAI_PRI_MI2S_RX,
18     MSM_FRONTEND_DAI_MULTIMEDIA6, 1, 0, msm_routing_get_audio_mixer,
19     msm_routing_put_audio_mixer),
20     SOC_SINGLE_EXT("MultiMedia7", MSM_BACKEND_DAI_PRI_MI2S_RX,
21     MSM_FRONTEND_DAI_MULTIMEDIA7, 1, 0, msm_routing_get_audio_mixer,
22     msm_routing_put_audio_mixer),
23     SOC_SINGLE_EXT("MultiMedia8", MSM_BACKEND_DAI_PRI_MI2S_RX,
24     MSM_FRONTEND_DAI_MULTIMEDIA8, 1, 0, msm_routing_get_audio_mixer,
25     msm_routing_put_audio_mixer),
26     SOC_SINGLE_EXT("MultiMedia9", MSM_BACKEND_DAI_PRI_MI2S_RX,
27     MSM_FRONTEND_DAI_MULTIMEDIA9, 1, 0, msm_routing_get_audio_mixer,
28     msm_routing_put_audio_mixer),
29 };

 1 static const struct snd_kcontrol_new primary_mi2s_rx_port_mixer_controls[] = {
 2     SOC_SINGLE_EXT("SEC_MI2S_TX", MSM_BACKEND_DAI_PRI_MI2S_RX,
 3     MSM_BACKEND_DAI_SECONDARY_MI2S_TX, 1, 0, msm_routing_get_port_mixer,
 4     msm_routing_put_port_mixer),
 5     SOC_SINGLE_EXT("TERT_MI2S_TX", MSM_BACKEND_DAI_PRI_MI2S_RX,
 6     MSM_BACKEND_DAI_TERTIARY_MI2S_TX, 1, 0, msm_routing_get_port_mixer,
 7     msm_routing_put_port_mixer),
 8     SOC_SINGLE_EXT("INTERNAL_FM_TX", MSM_BACKEND_DAI_PRI_MI2S_RX,
 9     MSM_BACKEND_DAI_INT_FM_TX, 1, 0, msm_routing_get_port_mixer,
10     msm_routing_put_port_mixer),
11     SOC_SINGLE_EXT("QUAT_MI2S_TX", MSM_BACKEND_DAI_PRI_MI2S_RX,
12     MSM_BACKEND_DAI_QUATERNARY_MI2S_TX, 1, 0, msm_routing_get_port_mixer,
13     msm_routing_put_port_mixer),
14     SOC_SINGLE_EXT("INTERNAL_BT_SCO_TX", MSM_BACKEND_DAI_PRI_MI2S_RX,
15     MSM_BACKEND_DAI_INT_BT_SCO_TX, 1, 0, msm_routing_get_port_mixer,
16     msm_routing_put_port_mixer),
17 };

以上我们定义了prior通道的控件和MultiMedia1数据流通道；

3.2 定义真正的widget，包含第一步定义好的dapm控件：

  1 static const struct snd_soc_dapm_widget msm_qdsp6_widgets[] = {
  2     /* Frontend AIF */
  3     /* Widget name equals to Front-End DAI name<Need confirmation>,
  4      * Stream name must contains substring of front-end dai name
  5      */
  6     SND_SOC_DAPM_AIF_IN("MM_DL1", "MultiMedia1 Playback", 0, 0, 0, 0),

snd_soc_dapm_route intercon

通过第一步的定义，我们知道PRI_RX Audio 的数据流通道为MultiMedia1；

很明显，我们可以知道：

MM_DL1连接到PRI_RX Audio Mixer的MultiMedia1

MM_DL2连接到PRI_RX Audio Mixer的MultiMedia2

。。。。

3.4 在msm_routing_probe函数中注册这些widget和路径：

1 snd_soc_dapm_new_controls(&platform->dapm, msm_qdsp6_widgets,
2                ARRAY_SIZE(msm_qdsp6_widgets));
3 snd_soc_dapm_add_routes(&platform->dapm, intercon,
4         ARRAY_SIZE(intercon));
