RE: EPP support in parport.c
The driver supplied in the 2.4 linux release is intended to be
as simple as possible. If you need higher transfer rates you
should use a DMA based implementation as you indicate.
We have a prototype for a DMA based ECP driver available but
no EPP driver. If all negotiation and direction changes are
handled by the framework it would be easy to add DMA EPP

Subject: EPP support in parport.c
Can someone explain me why in the parport.c code in the
arch/cris/drivers directory the epp and ecp functions point to the
software simulated functions and not the native read/write functions
that are supported by the ETRAX chip.
I need to interface a 'device bus' to the EPP port and would like to use
them, is it OK to modify the parport driver to use the native ones ?
