（高通平台）如何抓取各种音频日志？

1、logcat Log

	adb logcat -b main -b system -v threadtime > /data/logcat.txt 

2、kernel Log

//相应文件的log获取

	echo -n "file msm-compress-q6-v2.c +p" > /sys/kernel/debug/dynamic_debug/control 
    echo -n "file compress_offload.c +p" > /sys/kernel/debug/dynamic_debug/control 
    echo -n "file msm-pcm-q6-v2.c +p " > /sys/kernel/debug/dynamic_debug/control 
    echo -n "file msm-pcm-routing-v2.c +p" > /sys/kernel/debug/dynamic_debug/control 
    echo -n "file q6afe.c +p" > /sys/kernel/debug/dynamic_debug/control 
    echo -n "file q6adm.c +p" > /sys/kernel/debug/dynamic_debug/control 
    echo -n "file q6asm.c +p " > /sys/kernel/debug/dynamic_debug/control 
    echo "file rtac.c +p" > /sys/kernel/debug/dynamic_debug/control 
    echo "file audio_acdb.c +p" > /sys/kernel/debug/dynamic_debug/control 
    echo "file audio_calibration.c +p" > /sys/kernel/debug/dynamic_debug/control 
    echo "file audio_cal_utils.c +p" > /sys/kernel/debug/dynamic_debug/control 
    echo -n "file soc-dapm.c +p" > /sys/kernel/debug/dynamic_debug/control 
    echo -n "file soc-core.c +p > /sys/kernel/debug/dynamic_debug/control" 
    echo -n "file soc-pcm.c +p " > /sys/kernel/debug/dynamic_debug/control 
    adb shell cat /proc/kmsg > kernle

3、获取codec寄存器数值

获取高通pm8937相关寄存器数值（每次使用该命令需要重新获取节点路径）

	adb shell cat /sys/kernel/debug/asoc/msm8952-sku2-snd-card/codec:msm8x16_wcd_codec-ffffffc073859/codec_reg  > /data/codec_reg.txt
	cat /sys/kernel/debug/asoc/msm8939-snd-card-skul/msm8x16_wcd_codec-ffffffc072a08/codec_reg > /data/codec_log.txt

4、QXDM Log

5、QACT Log
