Hi all,
I have a device driver that implements a mmap in a char device. I would like to know if is possible to get notified(in that kernel module) every time a process change its mapped memory. Does anyone know if so?
hm, IMHO no, it doesn't know....unless your device send somekind of "feedback" everytime it gets read. Or, I know it's dirty....mark the related pages as read-only and intercept the fault? (would be not just dirty, but awful I think...) -- regards, Mulyadi Santosa Freelance Linux trainer and consultant blog: the-hydra.blogspot.com training: mulyaditraining.blogspot.com
