Comedi includes a driver for the National Instruments PCI-MIO E series,
which is now RT-compatible except for the A/D subsystem.
The problem I've run into is that the A/D subsystem needs an RT
interrupt when servicing RT requests, and non-RT interrupt when
servicing non-RT requests. It would be nice to have two interrupt
routines called for the same interrupt -- one RT, one regular
Linux. Unfortunately, I no longer have an RTLinux machine to
crash^H^H^H^H^Htest on.
btw: Other replies to this email revealed the existence of several
drivers I was not previously aware of. Any interest in making
these useful for others?
