Re: kmdf: Accessing data by isochronous transfer with 1394 device

I really thank you for your advices :-)

Could you please explain a little bit more precisely about page boundary?

Did you mean page boundary of physical or logical memory?
Should I use common buffer to start all buffers on a page boundary?

What kind of differences are there between starting buffers on a page
boundary
and not on a page boundary?

Sorry for many questions...

regards,
min

I'm using kmdf 1394 sample driver on WDK 6000
and I'm trying to access the transffered data in isochronous listen. (I
would like to take the transffered data and write it in a text file.)

Can somebody give me some advice or tips?

How (and when) can (or schould) I access the data? Has someone a example?

My idea is that I take the buffer in 't1394_IsochCallback' function,
because when DMA is completed to a buffer, it will call Callback
function.


It also seems to work better if your isochronous buffers all start on a
page boundary.
