Is there an eBPF equivalent for QNX? Also, with the real-time linux patch (which has been mainlined now), I'm able to run C++ ROS2 control loops @ 1ms down to even 250us on commodity off the shelf i3 and i5 hardware with dedicated cores.

I've worked on vxWorks, QNX and Linux and I found the pace of development using Linux the fastest.

Wouldn't that not make sense for QNX? eBPF is for running code in kernel space but QNX is a microkernel. The microkernel approach would be to just run another userspace program like any other program.

Good point! I was look at it from a users pov. Let's say I have a BPF script for monitoring a set of processes - their disk, network and CPU with some filters on specific messages. Now can I use it in qnx or what's the equivalent? It can run in userspace for all I care.
