Hi,
Anyone has ever tested the rte_kni.ko in igb mode? If the following is
confirmed as a bug, I would like to work out a patch. Thanks.
For file ~/dpdk/lib/librte_eal/linuxapp/kni/ethtool/igb/ igb_procfs.c, there
are following code. As to what I know, from Linux kernel 3.10.x, the functions
create_proc_read_entry() and create_proc_entry() are not supported anymore, so
we should use proc_create_data() for compatibility for both kernel 2.6 and
3.10.x and later versions.
/* called from igb_main.c */
int igb_procfs_init(struct igb_adapter *adapter)
{
......................
for (index = 0; ; index++) {
if (igb_proc_entries[index].read == NULL) {
break;
}
if (!(create_proc_read_entry(igb_proc_entries[index].name,
0444,
adapter->info_dir,
igb_proc_entries[index].read,
adapter))) {
rc = -ENOMEM;
goto fail;
}
}
