This is Mellanox SW steering parser and triggering for dump files in CSV format. The supported dump files are those generated by ConnectX5 and ConnectX6DX.
For JSON dump parser please move to branch json_parser.
Dump generation is available in:
1. rdma-core:
It can be done directly by calling mlx5dv_dump_dr_domain API or using mlx5_pmd
To trigger DPDK app run:
mlx_steering_dump_parser.py -p <DPDK PID> -f <dump_file>
2. mlnx-ofed kernel steering (SMFS):
Generated by reading the interface proc file under /proc/driver/mlx5_core/smfs_dump/fdb/<PCI>
For example:
cat /proc/driver/mlx5_core/smfs_dump/fdb/0000\:82\:00.0 > /dump_file
mlx_steering_dump_parser.py -f /dump_file
| Flags | meaning |
|---|---|
| -f | path to file |
| -r | show raw data |
| -t | Show steering tree/hierarchy |
| -p | Trigger DPDK app |
| -v | Verbose view |
| -vv | Extra verbose view |
| -c | show colored prints |
example.csv is part of this porject can be viewed using:
mlx_steering_dump_parser.py -f example.csv
mlx_steering_dump_parser.py -f example.csv -t
mlx_steering_dump_parser.py -f example.csv -v
mlx_steering_dump_parser.py -f example.csv -vv
Trigger a new testpmd dump using:
mlx_steering_dump_parser.py -p `pidof testpmd` -f new_dump.csv
Trigger a new kernel SMFS dump using:
cat /proc/driver/mlx5_core/smfs_dump/fdb/0000\:82\:00.0 > /new_dump.csv
mlx_steering_dump_parser.py -f /new_dump.csv
