Hi, We use fedora at work and are trying to port our driver from F7 to F9.
I am acting as gopher for our system architect so please be liberal with any commentary. I won't be able to post his feedback to any comments/questions (as necc.) until Tuesday evening.
I believe he wants our applications (running as non-root user) to be able to open his driver, and the driver to be able to run at real-time priority. We did this in F7 without any apparent issues.
Any help, comments, suggestions are greatly appreciated. --- John code and issues : struct sched_param param = {70}; kernel_cap_t effective, inheritable, permitted, all; cap_set_full(all); // be sure we have enough permissions to call // sched_setscheduler. // probably only need CAP_SYS_NICE, but let's be // "(un)safe" // save old permissions cap_capget(current,&effective, &inheritable, &permitted); // setup permissions to do this cap_capset_set(current,&all, &all, &all); // setup realtime priority ret=sched_setscheduler(current,SCHED_RR,¶m); // restore permissions cap_capset_set(current,&effective, &inheritable, &permitted); used to be able to do this in f7 / 2.6.23 kernel, now we get: WARNING: "cap_capset_set" [/usr/CSM/src/ONI/oni_driver/oni.ko] undefined!
