Hi,
I have tested netmap on freescale PowerPC board, it is a big endian
machine, when I test the example app pkt-gen， I found one bug, really it is
bug of netmap souce code.
The commit id is “d39c4411a2129926d262f9faffacaf876392c7cd”, the
bug locates in “netmap_mem2.c, netmap_mem_rings_create()”, you should use
“*(uint32_t *)(uintptr_t)&ring->nr_buf_size =
NETMAP_BDG_BUF_SIZE(na->nm_mem);” substituting
“*(uint16_t *)(uintptr_t)&ring->nr_buf_size =
NETMAP_BDG_BUF_SIZE(na->nm_mem);”
Because the outcome of big endian and little endian is different. I
guess the source code is written and tested on intel arch machine. But it is
true it can’t run big endian machine directly.
Best regards,
Dongshan
