Hello,
We need to support serial driver with real time requirements (towards specific device with RT demands):
Every 5.3msec receive 100 bytes and 1.3msec afterwards send 100 bytes.
1. Does kernel support real-time of such hard requirements ?
2. Is it matter if we do the exact bytes send/receive from kernel or userspace, i.e. is kernel more real-time than userspace ?
3. Is mainline kernel unable to support such requirements and we better use RT patch such as xemonai ?
Best Regards,
Ran
