RT_LINUX support for selective F'prime component

[ankrtlpixxel]

Hello,

Is there a way to run selective F'Prime components with RT-Linux support?
I’d like to enable real-time support only for my sensor read/write and algorithm components, rather than the entire deployment.

I don't believe you can enable/disable RT_LINUX per component as it is an OS property. However, you can adjust priorities in topology.fpp and subtopology configuration and set the remaining components to a lower priority. This would ensure that the sensor runs at the top priority.

Thanks, I also see that.

F'pirme scheduler is already configured with SCHED_RR , so no need to change anything, only support needed is kernel being RT.

namespace Task {
    std::atomic<bool> PosixTask::s_permissions_reported(false);
    static const PlatformIntType SCHED_POLICY = SCHED_RR;
