From: Ernesto Ramos on 28 Jul 2010 17:10 From: Rene Sapiens <rene.sapiens(a)ti.com> Use idr kernel library to send/receive node and stream ids to the user instead of kernel address. This id will be use to access the node and stream handles at the kernel side, if id does not match to any handle error -EFAULT is returned. For processor handle, dspbridge driver will make sure the handle is valid by using the handle stored in process context.
