[alsa-devel] print audio ring buffer in kernel space

Hello,

I am trying to print the ring buffer used for DMA transfer using ALSA in kernel space. I was able to print the ring buffer in user space after calling the snd_pcm_readi() function. But, wanted to know as to which file I need to be looking at to print the hardware buffer in kernel space as I am trying to debug capturing audio using ALSA.

I am using a MCBSP I2S on TM320DM365 processor and CQ93 on chip voice codec driver.

Appreciate any help as I am new to ALSA.

Thank you.
