You might want to look at the amplc_pc236.c driver, as it has a bunch of plx9052 definitions in it that might be useful, which you could split out into a plx9052 header file. > > So far I have commented out everything but the attach/detach routines, and > it is compiling and detecting the card. > > One other question; the check for availability of region BADR0 always > fails.

I believe the kernel does access that region to do generic pci stuff during bootup, but it doesn't keep it reserved. If I recall correctly, on your board BADR0 is memory-mapped (BADR1 is the same stuff except ioports). So you would want to do a request_mem_region() instead of request_region(). Or actually, pci_request_regions() is simplest. - -- Frank -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.0.6 (GNU/Linux) Comment: For info see http://www.gnupg.org iD8DBQE9yUff5vihyNWuA4URAn4bAKCK1cpII8DB5tUBFEm1S0RxE+Wg+gCgmqKX KvxT0xNKKmVmQrDdJWMr8V8= =6Mjp -----END PGP SIGNATURE-----
