Hello, I cannot make sense out of [lis_]request_region() function and need help on that.
As I understand ioremap() maps and returns virtual address for a given physical(bus) address associated with my PCI card. That is cool and clear. What is the purpose of request_region() and request_mem_region()? They both take physical address as a parameter, but do not return any virt addresses. 1. What do they allocate/reserve and where? 2. Should I call request_region() before doing ioremap() or not? 3. Why there is lis_request_region wrapper, but not for request_mem_region? The most important to me is question #2. thanks, -- Eugene __________________________________________________________________ McAfee VirusScan Online from the Netscape Network.
