NFP PMD has just had support for SRIOV VFs until now. This patch set adds support for the PF, but just for being used as another DPDK port. No VF management is added by now.
NFP is a programmable device and it supports virtual NICs (vNICs) through firmware implementation. Different firmware applications implement vNICs for PF devices and VF devices, being number of vNICs dependent on the firmware and the NFP card available. PF vNIC (virtual) BARs are a subset of PF PCI device BARs while VF vNIC BARs are same than VF PCI BARs. Working with VF vNICs requires a PF driver uploading the firmware, doing some NFP configuration and creating/destroying VFs. This can be only done with the kernel NFP PF netdev driver by now. Working with PF vNIC requires the PMD doing the NFP configuration and for accessing the NFP a specific user space interface is created. NFP Service Processor Userspace (NSPU) interface allows to create specific PCI BAR windows for accessing different parts of the NFP device, including the Network Service Processor (NSP) itself. The NSPU interface is implemented as the base for working with the PF. v2: - fix commits headers - update nic guide - add info to release notes - creating different features files for PF and VF - fix typo inside nfp_nspu.c Alejandro Lucero (18): net/nfp: add NSP user space interface net/nfp: add specific PF probe function net/nfp: add support for new PCI id net/nfp: add NSP support for commands net/nfp: add NSP FW upload command net/nfp: add NSP symbol resolution command net/nfp: add FW upload logic net/nfp: add support for vnic config bar mapping net/nfp: add support for vNIC Rx/Tx bar mappings net/nfp: support PF devices inside PMD initialization net/nfp: allocate ethernet device from PF probe function net/nfp: support PF multiport net/nfp: add NSP support for HW link configuration net/nfp: add support for HW port link configuration net/nfp: read PF port MAC addr using NSP doc: update NFP with PF support information doc: update release notes with NFP PF support doc: create different features files for NFP drivers doc/guides/nics/features/nfp.ini | 29 -- doc/guides/nics/features/nfp_pf.ini | 28 ++ doc/guides/nics/features/nfp_vf.ini | 28 ++ doc/guides/nics/nfp.rst | 77 +++- doc/guides/rel_notes/release_17_11.rst | 9 + drivers/net/nfp/Makefile | 2 + drivers/net/nfp/nfp_net.c | 382 +++++++++++++++++++- drivers/net/nfp/nfp_net_ctrl.h | 3 + drivers/net/nfp/nfp_net_eth.h | 82 +++++ drivers/net/nfp/nfp_net_pmd.h | 8 + drivers/net/nfp/nfp_nfpu.c | 103 ++++++ drivers/net/nfp/nfp_nfpu.h | 55 +++ drivers/net/nfp/nfp_nspu.c | 623 +++++++++++++++++++++++++++++++++ drivers/net/nfp/nfp_nspu.h | 83 +++++ 14 files changed, 1445 insertions(+), 67 deletions(-) delete mode 100644 doc/guides/nics/features/nfp.ini create mode 100644 doc/guides/nics/features/nfp_pf.ini create mode 100644 doc/guides/nics/features/nfp_vf.ini create mode 100644 drivers/net/nfp/nfp_net_eth.h create mode 100644 drivers/net/nfp/nfp_nfpu.c create mode 100644 drivers/net/nfp/nfp_nfpu.h create mode 100644 drivers/net/nfp/nfp_nspu.c create mode 100644 drivers/net/nfp/nfp_nspu.h -- 1.9.1
