SubjectSample device driver - 2.2 and 2.4 support?
I've been assigned a device driver that uses the old (2.0) PCI
support APIs - and is still working on 2.2.

I need to get this driver working on 2.2 and 2.4, I'm assuming I'll
need to go switch to the newer PCI stuff - but am curious about the
toleration support in later 2.2 kernels; is it complete enough that
I can migrate to 2.4, and still compile on 2.2?

The device:
1-2 DMA
1 IRQ

The driver:
mkalloc
__get_free_pages
virt_to_bus
request_irc
wake_up

The driver has similiar functionality to a sound card:
Send/Receive (possibly large) data to device via DMA (page fixing, etc)

Is there a cononical example (esp. wrt 2.2 <-> 2.4 changes) I should look
at ?

Thanks,
