I have a net_device driver that has a fairly large (1-2MB) set of stats that a user space process needs to read from time to time. I had assumed the optimal ipc mechanism would be shared memory. Now that I'm getting around to implementation of this side of the project I'm getting a bit stuck. All of the mmap examples I can find seem to be for character devices. Do I need a character device that implements mmap and proxies access to the net_device's stats, or is there a way to mmap directly to a net_device structure? Also, is this the excepted method when a userspace process needs to read large tables from a driver? thanks, -chris -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to ecartis@xxxxxxxxxxxx Please read the FAQ at http://kernelnewbies.org/FAQ
