I've sent this message to David S. Miller and Linus Torvalds before, but obviously neither of them was willing to reply.
-------
I'd like to know which requirements the MSR driver needs to meet in order to get included in the 2.1.x and 2.2.x kernels. I have received some suggestions now and I myself can't really decide on the quality of each solution.
a) character device
This is the currently implemented method. It was criticized by Linus and I get the problem. I believe that this way, it would be very easy to grant specific users access to the MSR registers.
b) character device (s.o.) + ioctl
Would it be good to implement some stuff via the ioctl functions?
c) /proc/sys + sysctl
Would this do any good? You could probably write to a file to select the MSR register/performance counter and then read from it. I'd love to do it that way, but access would be restricted to root. Is that okay?
Please add your thoughts on this.
