Re: systemtap for ixgbe driver on Fedora

Hi :
I tried to trace some function the driver/net ixgbe by systemtap, but it always fails with following errors:
[root@petpig demo]# lsmod|grep ixgbe
ixgbe 106084 1
dca 5152 1 ixgbe
mdio 3772 1 ixgbe


[root@petpig demo]# cat ixgbe.stp
probe kernel.function("ixgbe_fcoe_ddp_put") { log ("enter") }
probe kernel.function("ixgbe_fcoe_ddp_put").return { log ("exit") }

Seems ixgbe_fcoe_ddp_put is in separate module, not vmlinux.


Try probe module("ixgbe").function("ixgbe_fcoe_ddp_put")

Wenji
