Function Documentation

On PCD cards, sets DMA direction to read or write.

Most users will not need to use this function, but instead can just set the direction when calling edt_configure_ring_buffers().

Parameters

edt_p	Pointer to edt device structure returned by edt_open() or edt_open_channel()
direction	Either EDT_READ or EDT_WRITE (not both)

int edt_wakeup_dma ( Edt_Dev * edt_p )

called by edt_DpcForIsr

Allocate rbuf sg elements Assumes os.map already set up, so rbuf just needs pointers or copies of os.map

Count stats for all channels on a device:

int edt_initialize_vars ( Edt_Dev * edt_p )

Initialize board variables Assume that DmaChannel and Devid are set coming in

int edt_get_active_channels ( Edt_Dev * edt_p )

Go through all channels counting which ones are active

int edt_default_rbufs_from_type ( int id )

Initial value for number of rbufs
