SubjectAdding support for ARINC429 into the Linux kernel
Hi all,

I have been asked to explore options for adding ARINC 429 support [1]
into the Linux kernel, primarily to support devices from Holt Integrated
Circuits [2] (the request is unrelated to the chip manufacturer).

ARINC429 is a protocol which is widely used in commercial airplanes.

There are various chips supporting this protocol available, as well as
out-of-tree Linux support. The drivers I have looked at implement it
either as character device or misc device and typically pass raw receive
data to userspace.

I can see a number of options for going forward:
1) Implement as character device (or possibly misc device) and pass
raw data to/from user space
1a) Just implement a driver for the specific chips
2b) Implement some kind of generic infrastructure
2) Implement as network driver with a new address family, similar to,
say, AF_CAN.

Any thoughts / suggestions which approach would be better and, most of all,
which approach might have a better chance of being accepted upstream ?

Thanks,
Guenter
