I am relatively new to linux device development. And want to understand
Linux conventions.

Suppose I have a PCI card that is represented in the system by a
character device.

If I have two of those PCI cards in the system when the driver module
loads, is it convention to have two different major numbers, or have one
major number and two different minor numbers?

Thanks,

You can start your kernel hacking way from ldd. It can be found at:
http://lwn.net/Kernel/LDD3/

There are a few other books by R. Love or Greg KH that you can read.

Such questions are fully covered there.

Best,
