net: ti: am65-cpsw-nuss: Add devlink support

2021-02-12T01:52:13Z

AM65 NUSS ethernet switch on K3 devices can be configured to work either in independent mac mode where each port acts as independent network interface (multi mac) or switch mode. Add devlink hooks to provide a way to switch b/w these modes. Rationale to use devlink instead of defaulting to bridge mode is that SoC use cases require to support multiple independent MAC ports with no switching so that users can use software bridges with multi-mac configuration (e.g: to support LAG, HSR/PRP, etc). Also, switching between multi mac and switch mode requires significant Port and ALE reconfiguration, therefore is easier to be made as part of mode change devlink hooks. It also allows to keep user interface similar to what was implemented for the previous generation of TI CPSW IP (on AM33/AM43/AM57 SoCs). Signed-off-by: Vignesh Raghavendra Signed-off-by: David S.

devlink: expand the devlink-info documentation

2020-03-24T23:47:33Z

We are having multiple review cycles with all vendors trying to implement devlink-info. Let's expand the documentation with more information about what's implemented and motivation behind this interface in an attempt to make the implementations easier. Describe what each info section is supposed to contain, and make some references to other HW interfaces (PCI caps). Document how firmware management is expected to look, to make it clear how devlink-info and devlink-flash work in concert. Name some future work. v2: - improve wording v3: - improve wording Signed-off-by: Jakub Kicinski Reviewed-by: Randy Dunlap Signed-off-by: David S. Miller

ice: add basic handler for devlink .info_get

2020-03-21T08:00:32Z

The devlink .info_get callback allows the driver to report detailed version information. The following devlink versions are reported with this initial implementation: "fw.mgmt" -> The version of the firmware that controls PHY, link, etc "fw.mgmt.api" -> API version of interface exposed over the AdminQ "fw.mgmt.build" -> Unique build id of the source for the management fw "fw.undi" -> Version of the Option ROM containing the UEFI driver "fw.psid.api" -> Version of the NVM image format. "fw.bundle_id" -> Unique identifier for the combined flash image. "fw.app.name" -> The name of the active DDP package. "fw.app" -> The version of the active DDP package. With this, devlink dev info can report at least as much information as is reported by ETHTOOL_GDRVINFO. Compare the output from ethtool vs from devlink: $ ethtool -i ens785s0 driver: ice version: 0.8.1-k firmware-version: 0.80 0x80002ec0 1.2581.0 expansion-rom-version: bus-info: 0000:3b:00.0 supports-statistics: yes supports-test: yes supports-eeprom-access: yes supports-register-dump: yes supports-priv-flags: yes $ devlink dev info pci/0000:3b:00.0 pci/0000:3b:00.0: driver ice serial number 00-01-ab-ff-ff-ca-05-68 versions: running: fw.mgmt 2.1.7 fw.mgmt.api 1.5 fw.mgmt.build 0x305d955f fw.undi 1.2581.0 fw.psid.api 0.80 fw.bundle_id 0x80002ec0 fw.app.name ICE OS Default Package fw.app 1.3.1.0 More pieces of information can be displayed, each version is kept separate instead of munged together, and each version has an identifier which comes with associated documentation.
