Subject: [dpdk-dev] BUG: DPDK i40e does not work with VFIO
Date: Thu, 5 Nov 2015 09:19:25 -0800 [thread overview]
Message-ID: <20151105091925.0bbb0816@xeon-e3> (raw)
On my machine, i40e will not startup if using VFIO.
PMD: rte_i40evf_pmd_init(): >>
PMD: rte_i40e_pmd_init(): >>
PMD: eth_i40e_dev_init(): >>
PMD: i40e_set_symmetric_hash_enable_per_port(): Symmetric hash has already been disabled
PMD: eth_i40e_dev_init(): Failed to init adminq: -54
The normal Linux driver works correctly. Firmware has been updated to the latest version.
Like my earlier experience with fm10k, I suspect that Intel never tests i40e with IOMMU,
and only tested with igb_uio.
