I believe you're talking about the rtprio limit, or RLIMIT_RTPRIO option to setrlimit(2) call. That's still default to 0 (no real time privileges) on the kernel, which means it still requires admin action to enable. > I note that there are several calls to setPriority() found in the Qt > libraries, such as Qt3D. They're just no-op on Linux. As Tim said in his reply, applications can request RT priority from RTKit. -- Thiago Macieira - thiago.macieira (AT) intel.com Principal Engineer - Intel Platform & System Engineering
