Hi Greg

Yes I have read the book and some of it does make sense to me.

What doesnt make sense though is that my pci.h file that I have found 
/include/linux only has like 30 lines max?

None of the functions in the book are in the header.

Thanks
Testo

Hey Guys

Im writing a PCI driver in Linux ( Lubuntu ). Now its not an entire
driver its really just a little program that will latch onto a space of
ram and dump the entire content of the ram into a file.
I have done this before in a Unix/Linux based OS and it took me quite a
while to figure it out.

So at startup the configuration for the PCI is already done so I wont
have to do any of that myself.
I really just need to set a pointer to a register.

My problem is that I cant find the functions to do that for linux.
I cant find similar functions to things like :
PCI_ATTACH()
pci_attach_device();
mmap_device_memory();

I think that is really all I need at the moment.
Anybody have some ideas of where I can start looking?

Have you read the book, Linux Device Drivers, 3rd edition, it's free
online and has a whole chapter on PCI that should answer these questions
for you.

If not, please feel free to post your code and we will be glad to review
it.

thanks,
