RE: Building DPDK with IOVA_AS_VA

[Shijith Thotton <sthotton@marvell.com>]

Hi Jingjing Wu/Beilei Xing.

>I guess driver may not handle the attribute enable_iova_as_pa well right now.

Please send a fix. A check can be added similar to hns3 PMD. 

+if dpdk_conf.get('RTE_IOVA_AS_PA') == 0
+    build = false
+    reason = 'driver does not support disabling IOVA as PA mode'
+    subdir_done()
+endif
+

Thanks,
Shijith
