Dear Gagandeep, Hemant, We are facing a critical production outage on NXP LS1043A platforms running OVS-DPDK（ver:22.11.7）. Status:
* ✅ Your PFDR leak patch (bus/dpaa: fix PFDRs leaks due to FQRNIs) is applied * ❌ After ~90 days, PFDR still exhausts (from 524k to 487k entries) * ❌ Error: Qman ErrInt: PFDR Enqueues Blocked Interrupt * ❌ Device requires reboot to recover Your patch note states: "Please note that this drain_mr_fqrni() only look for FQRNI type messages to consume. If there are other type of messages like FQRN, FQRL, FQPN, ERN etc. also coming on MR then those messages need to be handled separately." We believe this is exactly our situation - other message types are accumulating and consuming PFDRs. Urgent request: * Are there known patches to handle FQRN, ERN, etc. messages? * Should we drain MR in additional locations (interrupt handlers, periodic timers)? * Can you provide a complete fix or point us to the right code modifications? We are willing to test any patch immediately. Our production systems are at risk. Please advise urgently.
