ixgbe: devlink: add devlink region support for E610

2025-04-29T22:13:44Z

Provide support for the following devlink cmds: -DEVLINK_CMD_REGION_GET -DEVLINK_CMD_REGION_NEW -DEVLINK_CMD_REGION_DEL -DEVLINK_CMD_REGION_READ ixgbe devlink region implementation, similarly to the ice one, lets user to create snapshots of content of Non Volatile Memory, content of Shadow RAM, and capabilities of the device. For both NVM and SRAM regions provide .read() handler to let user read their contents without the need to create full snapshots.

ixgbe: add device flash update via devlink

2025-04-15T14:36:32Z

Use the pldmfw library to implement device flash update for the Intel ixgbe networking device driver specifically for E610 devices. This support uses the devlink flash update interface. Using the pldmfw library, the provided firmware file will be scanned for the three major components, "fw.undi" for the Option ROM, "fw.mgmt" for the main NVM module containing the primary device firmware, and "fw.netlist" containing the netlist module. The flash is separated into two banks, the active bank containing the running firmware, and the inactive bank which we use for update. Each module is updated in a staged process. First, the inactive bank is erased, preparing the device for update. Second, the contents of the component are copied to the inactive portion of the flash. After all components are updated, the driver signals the device to switch the active bank during the next EMP reset. With this implementation, basic flash update for the E610 hardware is supported.

ixgbe: add initial devlink support

2025-04-15T14:36:32Z

Add an initial support for devlink interface to ixgbe driver. Similarly to i40e driver the implementation doesn't enable devlink to manage device-wide configuration. Devlink instance is created for each physical function of PCIe device. Create separate directory for devlink related ixgbe files and use naming scheme similar to the one used in the ice driver. Add a stub for Documentation, to be extended by further patches. Change struct ixgbe_adapter allocation to be done by devlink (Przemek), as suggested by Jiri.

net: intel: Use -y instead of -objs in Makefile

2024-06-11T02:52:44Z

*-objs suffix is reserved rather for (user-space) host programs while usually *-y suffix is used for kernel drivers (although *-objs works for that purpose for now). Let's correct the old usages of *-objs in Makefiles.

ixgbe/ixgbevf: fix XFRM_ALGO dependency

2018-10-31T17:53:15Z

Based on the original work from Arnd Bergmann. When XFRM_ALGO is not enabled, the new ixgbe IPsec code produces a link error: drivers/net/ethernet/intel/ixgbe/ixgbe_ipsec.o: In function `ixgbe_ipsec_vf_add_sa': ixgbe_ipsec.c:(.text+0x1266): undefined reference to `xfrm_aead_get_byname' Simply selecting XFRM_ALGO from here causes circular dependencies, so to fix it, we probably want this slightly more complex solution that is similar to what other drivers with XFRM offload do: A separate Kconfig symbol now controls whether we include the IPsec offload code. To keep the old behavior, this is left as 'default y'. The dependency in XFRM_OFFLOAD still causes a circular dependency but is not actually needed because this symbol is not user visible, so removing that dependency on top makes it all work.

ixgbe: add AF_XDP zero-copy Rx support

2018-10-03T19:51:14Z

This patch adds zero-copy Rx support for AF_XDP sockets. Instead of allocating buffers of type MEM_TYPE_PAGE_SHARED, the Rx frames are allocated as MEM_TYPE_ZERO_COPY when AF_XDP is enabled for a certain queue. All AF_XDP specific functions are added to a new file, ixgbe_xsk.c. Note that when AF_XDP zero-copy is enabled, the XDP action XDP_PASS will allocate a new buffer and copy the zero-copy frame prior passing it to the kernel stack.

net: intel: Cleanup the copyright/license headers

2018-04-27T18:00:04Z

After many years of having a ~30 line copyright and license header to our source files, we are finally able to reduce that to one line with the advent of the SPDX identifier. Also caught a few files missing the SPDX license identifier, so fixed them up.
