From 8210ff738077ed3581e022e5cc8721aa041d42cb Mon Sep 17 00:00:00 2001 From: Jedrzej Jagielski Date: Thu, 10 Apr 2025 15:00:01 +0200 Subject: [PATCH] ixgbe: add .info_get extension specific for E610 devices E610 devices give possibility to show more detailed info than the previous boards. Extend reporting NVM info with following pieces: fw.mgmt.api -> version number of the API fw.mgmt.build -> identifier of the source for the FW fw.mgmt.srev -> number defining FW's security revision fw.psid.api -> version defining the format of the flash contents fw.undi.srev -> number defining OROM's security revision fw.netlist -> version of the netlist module fw.netlist.build -> first 4 bytes of the netlist hash Co-developed-by: Slawomir Mrozowicz Signed-off-by: Slawomir Mrozowicz Co-developed-by: Piotr Kwapulinski Signed-off-by: Piotr Kwapulinski Signed-off-by: Jedrzej Jagielski Signed-off-by: Tony Nguyen --- .../networking/devlink/devlink-info.rst | 4 + Documentation/networking/devlink/ixgbe.rst | 38 ++++++ .../ethernet/intel/ixgbe/devlink/devlink.c | 128 +++++++++++++++++- 3 files changed, 167 insertions(+), 3 deletions(-) diff --git a/Documentation/networking/devlink/devlink-info.rst b/Documentation/networking/devlink/devlink-info.rst index 23073bc219d8..dd6adc4d0559 100644 --- a/Documentation/networking/devlink/devlink-info.rst +++ b/Documentation/networking/devlink/devlink-info.rst @@ -86,6 +86,10 @@ In case software/firmware components are loaded from the disk (e.g. ``/lib/firmware``) only the running version should be reported via the kernel API. +Please note that any security versions reported via devlink are purely +informational.
