The primary purpose of the Virtual bus is to put devices on it and hook the devices up to drivers. This will allow drivers, like the RDMA drivers, to hook up to devices via this Virtual bus. The associated irdma driver designed to use this new interface, is still in RFC currently and was sent in a separate series. A new RFC version is expected later this week. This series currently builds against net-next tree. Revision history: v2: Made changes based on community feedback, like Pierre-Louis's and Jason's comments to update virtual bus interface. v3: Updated the virtual bus interface based on feedback from Jason and Greg KH. Also updated the initial ice driver patch to handle the virtual bus changes and changes requested by Jason and Greg KH. The following are changes since commit f989d546a2d5a9f001f6f8be49d98c10ab9b1897: erspan: Add type I version 0 support. and are available in the git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/next-queue 100GbE Dave Ertman (7): Implementation of Virtual Bus ice: Create and register virtual bus for RDMA ice: Complete RDMA peer registration ice: Support resource allocation requests ice: Enable event notifications ice: Allow reset operations ice: Pass through communications to VF Shiraz Saleem (2): i40e: Move client header location i40e: Register a virtbus device to provide RDMA Documentation/driver-api/virtual_bus.rst | 88 ++ MAINTAINERS | 1 + drivers/bus/Kconfig | 10 + drivers/bus/Makefile | 2 + drivers/bus/virtual_bus.c | 255 ++++ drivers/infiniband/hw/i40iw/Makefile | 1 - drivers/infiniband/hw/i40iw/i40iw.h | 2 +- drivers/net/ethernet/intel/Kconfig | 2 + drivers/net/ethernet/intel/i40e/i40e.h | 2 +- drivers/net/ethernet/intel/i40e/i40e_client.c | 133 +- drivers/net/ethernet/intel/ice/Makefile | 1 + drivers/net/ethernet/intel/ice/ice.h | 14 + .../net/ethernet/intel/ice/ice_adminq_cmd.h | 33 + drivers/net/ethernet/intel/ice/ice_common.c | 206 ++- drivers/net/ethernet/intel/ice/ice_common.h | 9 + drivers/net/ethernet/intel/ice/ice_dcb_lib.c | 68 + drivers/net/ethernet/intel/ice/ice_dcb_lib.h | 3 + .../net/ethernet/intel/ice/ice_hw_autogen.h | 1 + drivers/net/ethernet/intel/ice/ice_idc.c | 1344 +++++++++++++++++ drivers/net/ethernet/intel/ice/ice_idc_int.h | 105 ++ drivers/net/ethernet/intel/ice/ice_lib.c | 50 + drivers/net/ethernet/intel/ice/ice_lib.h | 4 + drivers/net/ethernet/intel/ice/ice_main.c | 105 +- drivers/net/ethernet/intel/ice/ice_sched.c | 69 +- drivers/net/ethernet/intel/ice/ice_switch.c | 27 + drivers/net/ethernet/intel/ice/ice_switch.h | 4 + drivers/net/ethernet/intel/ice/ice_type.h | 4 + .../net/ethernet/intel/ice/ice_virtchnl_pf.c | 59 +- include/linux/mod_devicetable.h | 8 + .../linux/net/intel}/i40e_client.h | 15 + include/linux/net/intel/iidc.h | 337 +++++ include/linux/virtual_bus.h | 62 + scripts/mod/devicetable-offsets.c | 3 + scripts/mod/file2alias.c | 7 + 34 files changed, 2970 insertions(+), 64 deletions(-) create mode 100644 Documentation/driver-api/virtual_bus.rst create mode 100644 drivers/bus/virtual_bus.c create mode 100644 drivers/net/ethernet/intel/ice/ice_idc.c create mode 100644 drivers/net/ethernet/intel/ice/ice_idc_int.h rename {drivers/net/ethernet/intel/i40e => include/linux/net/intel}/i40e_client.h (94%) create mode 100644 include/linux/net/intel/iidc.h create mode 100644 include/linux/virtual_bus.h
