| |
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 ?
