Just achieved a rock-solid 8µs max jitter on a standard 500€ PC (codename: Katana) using a custom Buildroot env and Kernel 6.12.57-rt14.
The craziest part? It’s running off a 2015 USB 2.0 stick! 🤯
16 threads stress-tested (cyclictest)
cpu_dma_latency set to 0µs
Average jitter: 1µs
Zero tuning in BIOS

@nickbearded Are you also going to test with 6.18? #linux #rtos
