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, greg k-h
