Alright soo I want to access a piece of allocated memory through the PCI device which is PLX9054 chip. All I really need to do is gain access to it and dump the data from it into a file. Now the user space one would have been nice if I could use it but the PCI.H in user space dev folder " /usr/include " is really limiting OR I just dont know how I can do it with only the 8 or so functions given to me there. Also I think permissions might be a problem in user space. Because as far as I know accessing a PCI devices Memory you need to populate a struct with and give it a handle and then pass it on to mmap() if im not mistaken. But I cant even get to try and code it cause at the moment I cant even seem to get the environment/makefiles set up correctly to be able to link all of the needed .H files and libraries in.
