Hello Wenzhuo,
I'm testing this patchset, but I am sporadically running into an issue
where the VFs reset fails after the PF flaps.
I have a VM running on a KVM box with a X540-AT2, passing 2 VFs in.
I am using calling rte_eth_dev_reset in response to a
RTE_ETH_EVENT_INTR_RESET callback, and the following errors appear in
the log:
PMD: ixgbevf_dev_reset(): Ixgbe VF reset: Failed to update link.
PMD: ixgbe_alloc_rx_queue_mbufs(): RX mbuf alloc failed queue_id=0
PMD: ixgbevf_dev_start(): Unable to initialize RX hardware (-12)
PMD: ixgbevf_dev_reset(): Ixgbe VF reset: Failed to start device.
Jumping in with GDB, it seems that the rte_rxmbuf_alloc call in
ixgbe_alloc_rx_queue_mbufs returns NULL at iteration 64 out of 2048.
The application has ~500 2MB hugepages, and there's 2GB of free memory
available on top of that.
Have you seen this before? Any pointer or suggestion for debugging?
Thanks!
