Hi Yalei,
You have an example of how to write a vcl.conf file in vcl/vcl_test.conf. It’s
just an example, so if you want to try out eventfd, here’s what I’ve been
recently using:
vcl {
rx-fifo-size 4000000
tx-fifo-size 4000000
app-scope-local
app-scope-global
api-socket-name /run/vpp-api.sock
use-mq-eventfd
}
For this to work, vpp must come up with the binary api socket transport
configured and the session layer event queues must be allocated in a memfd
segment. So, add the following to your vpp startup conf:
socksvr { socket-name /run/vpp-api.sock }
session { evt_qs_memfd_seg }
Also, to have vcl read your config file, remember to do something like: "export
VCL_CONFIG=/path/to/your/file”. Finally, this is still very much ongoing work
so if you hit any issues, do let me know :-)
Hope this helps,
Florin
