在Linux源码里,Aduio这一部分现在是一个独立文件夹叫sound,在2.x的版本时,sound这个目录是在drivers里的,后来从这个里面剥离出来了,很多人不知道其中的原因,我也不知道,我们先回顾一下这段历史,当时Linux主线的audio还在使用OSS架构,一开始是在drivers里,后来就把OSS架构这个audio剥离出来了,可能是因为OSS走向了商业化的原因,后来因为商业化导致版权问题,ALSA就出现了,同样代码都在sound里,就这样一直延续了下来.
下边我们先来介绍一下Audio的基础知识,先从接口开始,常见接口有3种(IIS/ PCM/ AC'97):
IIS
Integrated Interchip Sound,这种接口跟IIC差不多,因为都是同一个公司:Philips做的,用于数字音频数据在系统内器件之间传输,例如编解码器CODEC、DSP、数字输入/输出接口、ADC、DAC和数字滤波器等。其与IIC无关联,这一点是需要注意的,IIS是个相对来说简单的接口协议,没有地址和片选机制,在总线上,只能同时存在一个主设备和发射设备;提供时钟的设备为主设备,可以是发射设备也可以是接收设备,或者是协调两者的其他控制设备。
IIS协议定义三根信号线:时钟信号SCK、数据信号SD和左右声道选择信号WS,如下如:
SCK:模块内的同步信号,从模式时由外部提供,主模式时由内部产生;
SD:串行数据,以二进制补码形式在数据线上传输;在WS变化后的第一个SCK脉冲,MSB先行;
WS:帧时钟,其电平变化频率等于声音采样率,高电平和低电平状态就是左右声道区分的状态;
IIS的操作模式有3种: 标准模式, 左对齐模式和右对齐模式.
标准模式:是左对齐模式延迟一个时钟位变化来的,左右通道的数据MSB均是在WS变化后第二个SCK/BCLK上升沿有效.
左对齐模式:标准左对齐格式的数据的MSB没有相对于BCLK延迟一个时钟。左对齐格式的左右声道数据的MSB在WS边沿变化后SCK/BCLK的第一个上升沿有效,支持16~32bit字长格式.
右对齐模式:接收设备必须事先知道待传数据的字长,目前是索尼公司采用这种格式.
这3种模式下,WS线的意义是不同的,在标准模式下的WS时钟高电平为右声道，低电平为左声道，左右对齐模式刚好相反.
SCK = 采样率(48K、44.1K、16K等) x 字长(16bit、24bit、32bit) x 2(左右两通道);
PCM
Pulse Code Modulation,是通过等时间隔(即采样率时钟周期)采样将模拟信号数字化的方法.接口传输的音频数据是通过PCM方式采样得到的,区别于PDM形式;IIS传输的也是PCM类型数据,属于其一个特例。相比于IIS,PCM接口更加灵活,通过时分复用TDM方式,PCM接口支持多大N个声道的数据.TDM不像IIS有统一标准,不同厂家TDM时有差异。
| PCM Interface | IIS Interface |
| PCM_OUT | SD_OUT |
| PCM_IN | SD_IN |
| PCM_SYNC | WS |
| PCM_CLK | SCK |
接口名称有如下规律：
PCM：传输单声道数据,比如麦克风；
IIS：传输双声道数据,比如喇叭；
TDM：传输两个以上声道数据,同时区别于IIS特定格式。
根据SD相对于FSYNC的位置,TDM分两种基本模式:
Mode A: 数据在FSYNC有效后,BCLK的第二个上升沿有效;
Mode B: 数据在FSYNC有效后,BCLK的第一个上升沿有效;
不同厂商对于两种模式的定义可能有点差别。
FSYNC的高电平等于一个BCLK的周期，其频率就等于采样率，与通道数无关。
BCLK的频率会随通道数的增加成倍数增加：8 × 32 × 48kHz ＝ 12.288 MHz。
其中又分为长帧同步和短帧同步:
>短帧同步:一个脉冲宽度等于一个BCLK的周期长度
>长帧同步:一个脉冲宽度等于一个slot的长度
AC'97
AC97是以Intel为首的5个PC厂商,在1997年共同提出的规格标准。与PCM/I2S不同:AC97不只是一种数据格式,它还具有控制功能。AC'97采用AC-Link与外部的编解码器相连,AC-Link接口包括:
(1)位时钟(BITCLK)
(2)同步信号校正(SYNC)
(3)从编码到处理器及从处理器中解码(SDATDIN与SDATAOUT)的数据队列
AC'97数据帧以SYNC脉冲开始,包括12个20位时间段(时间段为标准中定义的不同的目的服务)及16位“tag”段,共计256个数据序列。下图是AC97的接口图:
在全志A33上,支持PCM,IIS,所以,这里也只讨论这两种接口,下面,我们先通过外围电路了解A33上audio相关内容,先看一下电路图:
CPU部分:
耳机部分:
扬声器部分:
MIC部分:
剩下还有一些电路的供电,稳压等这里就不贴出来了,我们这里以CPU部分来说明,因为这部分比较抽象,容易说,每个管脚的意义如下面这个表格所示:
| Signal Description | ||
| Signal Name | Type | Description |
| HBIAS | OUT | 耳机偏置电压 |
| MBIAS | OUT | 主麦克偏置电压 |
| PHONEOUTP | OUT | 听筒正极输出 |
| PHONEOUTN | OUT | 听筒负极输出 |
| MICIN1P | IN | 主麦克正极输入 |
| MICIN1N | IN | 主麦克负极输入 |
| MICIN2P | IN | 副麦克正极输入 |
| MICIN2N | IN | 副麦克负极输入 |
| PHONEP | IN | 听筒正极输入 |
| PHONEN | IN | 听筒负极输入 |
| LINEINL | IN | 左输入行 |
| LINEINR | IN | 右输入行 |
| HPCOMFB | IN | 耳机基准电压反馈 |
| HPCOM | OUT | 耳机基准电压 |
| HPOUTL | OUT | 耳机左声道 |
| HPOUTR | OUT | 耳机右声道 |
| Power Description | ||
| VRA1 | OUT | 参考电压 |
| VRA2 | OUT | 参考电压 |
| VRP | OUT | 参考电压 |
| AVCC | IN | 模拟电压 |
| HPVCCIN | IN | 耳机放大器电源 |
| HPVCCBP | OUT | 耳机放大器功率旁路 |
| AGND | GND | 模拟电压地线 |
其中标注蓝色字体的是实际硬件用到的,这里扬声器和耳机共用耳机声道,硬件上通过PA-SHDN引脚(PH9)进行切换,以上内容就是SoC给我们暴露的实际引脚,情况是这个样子的,就是音频编解码器是在SoC内部的,我们用的是片上外设,比买一个音频芯片要省出来一些钱,然后SoC内部,音频编解码器对SoC暴露PCM/IIS接口(因为IIS是PCM的特例,硬件结构类似,通过软件配置,即可实现切换接口),对外部直接暴露驱动外设的接口,本质上外部接口就是ADC,DAC,我们看一下datasheet上音频编解码器的大致框架图,因为寄存器比较多,有100多个,这里就不列举出来了:
有了基本的一个audio硬件的概念之后,我们就来学习ALSA框架,之后,后边结合代码看一下,下面说一下ALSA的一些基本知识,推荐一下这个人写的音频系列教程,特详细,此处就是借鉴他的:https://blog.csdn.net/DroidPhone
概述
上图展现了在Linux上Audio的ALSA架构,用户空间的alsa-lib对应用程序提供统一的API接口,这样可以隐藏了驱动层的实现细节,简化了应用程序的实现难度。内核空间中,alsa-soc其实是对alsa-driver的进一步封装,它针对嵌入式设备提供了一些列增强的功能.

controlC0 --> 用于声卡的控制,例如通道选择,混音,麦克风的控制等
midiC0D0 --> 用于播放midi音频
pcmC0D0c --> 用于录音的pcm设备
pcmC0D0p --> 用于播放的pcm设备
seq --> 音序器
timer --> 定时器其中,C0D0代表的是声卡0中的设备0,pcmC0D0c最后一个c代表capture,pcmC0D0p最后一个p代表playback,这些都是alsa-driver中的命名规则。在我这用的这个平板上,设备没有这么多,只有下面这几个:

crw-rw---- system audio 116, 33 1970-01-11 10:04 timer目录树大概是这么一种情况:
下面对这些文件做一个大概的介绍:
| core | 该目录包含了ALSA驱动的中间层,它是整个ALSA驱动的核心部分 |
| core/oss | 包含模拟旧的OSS架构的PCM和Mixer模块 |
| core/seq | 有关音序器相关的代码 |
| include | ALSA驱动的公共头文件目录,该目录的头文件需要导出给用户空间的应用程序使用,通常,驱动模块私有的头文件不应放置在这里 |
| drivers | 放置一些与CPU、BUS架构无关的公用代码 |
| i2c | ALSA自己的I2C控制代码 |
| pci | pci声卡的顶层目录,子目录包含各种pci声卡的代码 |
| isa | isa声卡的顶层目录,子目录包含各种isa声卡的代码 |
| soc | 针对system-on-chip体系的中间层代码 |
| soc/codecs | 针对soc体系的各种codec的代码，与平台无关 |
我们要操作的代码就在soc目录中,这部分是和厂商相关的,全志的是soc/sunxi.
下面我们分析一下代码结构以及实际的代码,通过分析menuconfig, Makefile, Kconfig以及.o文件,绘制了下面这张图:
其中,core部分是通用的,我们主要移植内容是SoC部分,此部分一般有厂商提供,此处全志是提供了的,全志提供的这部分内容,大多也是通用于全志平台的芯片,不同芯片区别就是类似于sun8iw5_sndcodec.c这种文件,sun8iw5代表A33,sun8iw7代表H3,这个根据实际情况配置的,其它部分大多数情况下通用,因为时间原因,这里不能深入探讨具体实现框架,后边,真正有空了,会对整个子系统进行深入研究,也会分享出来,我们这里就贴一下差异部分代码,sun8iw5_sndcodec.c
