pointer callback in pcm

[Adrian McMenamin <adrian@mcmen.demon.co.uk>]

The documentation states:

"This callback is called when the PCM middle layer inquires the current
hardware position on the buffer."


Does that mean the position the hardware is at (in its ring buffer in my
case) or does it mean the position we are at in the dma buffer.

ie I have a 128k DMA buffer which transfers samples into the 32k
hardware memory buffer. Which position am I meant to be reporting?
