Additionally, I wanted to mention another relevant use case that wasn’t brought up earlier: fwctl can expose event records tagged with raw cycle counter timestamps. When the device is in free-running mode, correlating those with host time becomes difficult unless user space has access to both cycle and system time snapshots.
Okay, so DPDK and DOCA, got it.
