Hello,

Thank you for your suggestion.
I think you should send a patch on the mailing list to re-enable it.

Hi Thomas,

According to commit no. (*d92c66f5ac53a7b803efcb4782e601ea99c38a7e*) we
can't create KNI on 32 bit system b'coz

*lib/librte_eal/linuxapp/kni/kni_misc.c:304:2: error: format '%llx'

expects

quoted

argument of type 'long long unsigned int', but argument 2 has type
'phys_addr_t' [-Werror=format*]

It is because by default in 32 bit kernel *High Memory Support* option of
make menuconfig is selected with size 4 GB, therefore it gives

compilation

quoted

error.

Thus to use KNI on 32 bit system we need kernel with High memory support

of

quoted

64 GB, i.e  *PAE* (*Physical Address Extension*) *Support*, then we can

be

quoted

able to use it in 32 bit environment.

hope you will update this on dpdk.org


Regards,

Neeraj
