README on How-to run odp app on isolated core for no_hz_full kernel mode.
- Disbale timer init in odp application.
- avoid using odp's cpuset. Let odp thread launch unpinned.
- use odp-on-isolated-cpu.sh script to pin odp dp thread to
dplane cpuset.
- download my local test-definition repo link [1]
- copy odp_isolation binary to /usr/local/bin
- run ./common/scripts/odp-on-isolated-cpu.sh
Or
- ./common/scripts/odp-on-isolated-cpu.sh 1,2 "odp_isolation -l 1,2"
- Above script shows isolation duration, before / after interrupt count.
Known issue :
- x86 hw generates spurious ipi lead to break no_hz_full isolation (todo).
