just want to know before I buy, is the RT patch/TRLinux on Xavier a hard real time system ? can it guarantee the time slice to be consistence without affected by the CPU load ?
here is the command I apply the patches:
…Jetpak-4.2/sources/kernel/kernel/kernel-4.9$ ./scripts/rt-patch.sh apply-patches
PREEMPT RT patches successfully applied for Auto!
PREEMPT RT patches successfully applied for L4T!
Linux Kernel with PREEMPT_RT patches has less non-preemptible code resulting in lesser latencies and faster response times but it’s not purely hard realtime.
Concurrent Real-Time has released RedHawk Linux kernel on Jetson AGX Xavier. RedHawk Linux kernel is a hard real-time kernel which provides low latency with deterministic response without being affected by the CPU load.
