Hi,
Thank You For Your response.
There is one more case. we are observing rx buffer allocation error in
vppctl show hardware output. this error rx buffer allocation failure is
happening in the dpdk vmxnet3_recv_pkts() function.
rx q0 rx buf alloc failure 8846166
rx q1 rx buf alloc failure 6245832
tx q0 drop total 26052
tx q0 tx ring full 152
tx q1 drop total 18
tx q1 tx ring full 17
Adding vppctl show buffers and vppctl show dpdk buffers commands output
below.
./bin/vppctl show buffers
Pool Name Index NUMA Size Data Size Total Avail Cached
Used
default-numa-0 0 0 2496 2048 537600 527296 748
9556
./bin/vppctl show dpdk buffer
name="vpp pool 0" available = 985 allocated = 536615 total = 537600
We can see from the above two buffers output, vpp allocates all the dpdk
mbuf buffers to vlib_buffers.
Is it the reason we are observing the above rx buffer allocation error?
Thanks,
Sunil
