Message-Id: <20191209224935.1780117-1-jeffrey.t.kirsher@intel.com> Date: Mon, 9 Dec 2019 14:49:15 -0800 From: Jeff Kirsher <jeffrey.t.kirsher@...el.com> To: davem@...emloft.net, gregkh@...uxfoundation.org Cc: Jeff Kirsher <jeffrey.t.kirsher@...el.com>, netdev@...r.kernel.org, linux-rdma@...r.kernel.org, nhorman@...hat.com, sassmann@...hat.com, jgg@...pe.ca, parav@...lanox.com Subject: [net-next v3 00/20][pull request] Intel Wired LAN Driver Updates 2019-12-09 This series contains the initial implementation of the Virtual Bus, virtbus_device, virtbus_driver, updates to 'ice' and 'i40e' to use the new Virtual Bus and the new RDMA driver 'irdma' for use with 'ice' and 'i40e'. The primary purpose of the Virtual bus is to provide a matching service and to pass the data pointer contained in the virtbus_device to the virtbus_driver during its probe call. This will allow two separate kernel objects to match up and start communication. The last 16 patches of the series adds a unified Intel Ethernet Protocol driver for RDMA that supports a new network device E810 (iWARP and RoCEv2 capable) and the existing X722 iWARP device. The driver architecture provides the extensibility for future generations of Intel hardware supporting RDMA. The 'irdma' driver replaces the legacy X722 driver i40iw and extends the ABI already defined for i40iw. It is backward compatible with legacy X722 rdma-core provider (libi40iw). This series currently builds against net-next tree AND the rdma "for-next" branch. v1: Initial virtual bus submission v2: Added example virtbus_dev and virtbus_drv in tools/testing/sefltests/ to test the virtual bus and provide an example on how to implement v3: Added ice and i40e driver changes to implement the virtual bus, also added the new irdma driver which is the RDMA driver which communicates with the ice and i40e drivers The following are changes since commit 4a63ef710cc3e79ce58b46b122118e415a44b3db: Merge branch 'for-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/bluetooth/bluetooth-next and are available in the git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/next-queue rdma Dave Ertman (3): virtual-bus: Implementation of Virtual Bus ice: Initialize and register a virtual bus to provide RDMA ice: Implement peer communications Michael J.
