Bug ID: 715
Summary: Remove iavf DPDK code modifications from
DPDKdut.build_install_dpdk
Product: DTS
Version: unspecified
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: normal
Priority: Normal
Component: framework
Assignee: dts@dpdk.org
Reporter: juraj.linkes@pantheon.tech
Target Milestone: ---
The code in question is this:
DPDKdut.build_install_dpdk:
if nic_name in ['fortpark_TLV', 'fortpark_BASE-T']:
self.send_expect("sed -i '/{ RTE_PCI_DEVICE(IAVF_INTEL_VENDOR_ID,
IAVF_DEV_ID_ADAPTIVE_VF) },/i { RTE_PCI_DEVICE(IAVF_INTEL_VENDOR_ID,
IAVF_DEV_ID_X722_VF) },' drivers/net/iavf/iavf_ethdev.c", "# ")
self.send_expect("sed -i '/I40E_DEV_ID_X722_VF/d'
drivers/net/i40e/i40e_ethdev_vf.c", "# ")
elif kernel_driver == 'i40e':
self.send_expect("sed -i '/{ RTE_PCI_DEVICE(IAVF_INTEL_VENDOR_ID,
IAVF_DEV_ID_ADAPTIVE_VF) },/a { RTE_PCI_DEVICE(IAVF_INTEL_VENDOR_ID,
IAVF_DEV_ID_VF) },' drivers/net/iavf/iavf_ethdev.c", "# ")
self.send_expect("sed -i -e '/I40E_DEV_ID_VF/s/0x154C/0x164C/g'
drivers/net/i40e/base/i40e_devids.h", "# ")
I believe this enables iavf support for VFs with i40e PF driver. We need to
find a way to enable iavf for these devices without modifying DPDK code.
The first thing to do is to investigate whether that's possible with the
current DPDK implementation. If not, we need to agree with DPDK devs on a
proper solution. If that's the case, we'd only make the necessary DTS changes
after that.
