hello, my name is ilya, i am a kernel newbie, and i just joined the list in hopes of getting some insight on linux device driver development. i am writing a kernel-mode driver for a pci card and i need a mechanism to control the device via user-space application. at first i had an additional character driver initialized along with my driver and using fread/fwrite i would transfer info back and forth. then i found out about sysfs, so now i am using files in sysfs to send "commands" to the driver and receive data back. i have a feeling, however, that i am abusing this method. what is the appropriate way of setting this up? is there a way for the module to notify an application of some event happening? because right now i do this by constantly reading from one of the files in sysfs until the value it holds changes. i also know that reading files from kernel-mode is not a good thing, but i want to implement something of a config file that can be modified from user-space but would be read in by the module. what is the best way of doing this? any info is much appreciated. -- ilya -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to ecartis@xxxxxxxxxxxx Please read the FAQ at http://kernelnewbies.org/FAQ
