We encountered an issue where the kernel thread `ksmd` runs on the PMD dedicated isolated core, leading to high latency in OVS packets.
Upon analysis, we discovered that this is caused by the current select_idle_smt() function not taking the sched_domain mask into account.
Kernel version: linux-4.19.y
You do know that 4.19.y is long end-of-life and totally insecure and nothing that you should be using in anything, right? Please move to a more modern kernel version.
good luck!
