589e934d2735b55fbe68517128668df7af3ac4ae - net: phy: Introduce PHY ports representation

Thu, 08 Jan 2026 09:00:28 +0100

net: phy: Introduce PHY ports representationEthernet provides a wide variety of layer 1 protocols and standards fordata transmission. The front-facing ports of an interface have their owncomplexity and configurability.Introduce a representation of these front-facing ports. The current codeis minimalistic and only support ports controlled by PHY devices, butthe plan is to extend that to SFP as well as raw Ethernet MACs thatdon't use PHY devices.This minimal port representation allows describing the media and numberof pairs of a BaseT port. From that information, we can derive thelinkmodes usable on the port, which can be used to limit thecapabilities of an interface.For now, the port pairs and medium is derived from devicetree, definedby the PHY driver, or populated with default values (as we assume thatall PHYs expose at least one port).The typical example is 100M ethernet. 100BaseTX works using only 2pairs on a Cat 5 cables. However, in the situation where a 10/100/1000capable PHY is wired to its RJ45 port through 2 pairs only, we have noway of detecting that. The "max-speed" DT property can be used, but amore accurate representation can be used :mdi { connector-0 { media = "BaseT"; pairs = <2>; };};From that information, we can derive the max speed reachable on theport.Another benefit of having that is to avoid vendor-specific DT properties(micrel,fiber-mode or ti,fiber-mode).This basic representation is meant to be expanded, by the introductionof port ops, userspace listing of ports, and support for multi-portdevices.Reviewed-by: Christophe Leroy Signed-off-by: Maxime Chevallier Reviewed-by: Andrew Lunn Link: https://patch.msgid.link/20260108080041.553250-4-maxime.chevallier@bootlin.comSigned-off-by: Jakub Kicinski List of files: /linux/drivers/net/phy/Makefile

a3e1c0ad835702555d90565584ab6f723adf7f94 - net: phy: factor out provider part from mdio_bus.c

Tue, 29 Apr 2025 08:04:46 +0200

net: phy: factor out provider part from mdio_bus.cAfter 52358dd63e34 ("net: phy: remove function stubs") there's aproblem if CONFIG_MDIO_BUS is set, but CONFIG_PHYLIB is not.mdiobus_scan() uses phylib functions like get_phy_device().Bringing back the stub wouldn't make much sense, because it wouldallow to compile mdiobus_scan(), but the function would be unusable.The stub returned NULL, and we have the following in mdiobus_scan():phydev = get_phy_device(bus, addr, c45); if (IS_ERR(phydev)) return phydev;So calling mdiobus_scan() w/o CONFIG_PHYLIB would cause a crash later inmdiobus_scan(). In general the PHYLIB functionality isn't optional here.Consequently, MDIO bus providers depend on PHYLIB.Therefore factor it out and build it together with the libphy coremodules. In addition make all MDIO bus providers under /drivers/net/mdiodepend on PHYLIB. Same applies to enetc MDIO bus provider. Note thatPHYLIB selects MDIO_DEVRES, therefore we can omit this here.Fixes: 52358dd63e34 ("net: phy: remove function stubs")Reported-by: kernel test robot Closes: https://lore.kernel.org/oe-kbuild-all/202504270639.mT0lh2o1-lkp@intel.com/Reviewed-by: Jacob Keller Signed-off-by: Heiner Kallweit Link: https://patch.msgid.link/c74772a9-dab6-44bf-a657-389df89d85c2@gmail.comSigned-off-by: Jakub Kicinski List of files: /linux/drivers/net/phy/Makefile

d8c838a57ce25c746c9882ffa427d8bb3f22b526 - net: phy: Use an internal, searchable storage for the linkmodes

Fri, 07 Mar 2025 18:35:59 +0100

net: phy: Use an internal, searchable storage for the linkmodesThe canonical definition for all the link modes is in linux/ethtool.h,which is complemented by the link_mode_params array stored innet/ethtool/common.h . That array contains all the metadata about eachof these modes, including the Speed and Duplex information.Phylib and phylink needs that information as well for internalmanagement of the link, which was done by duplicating that informationin locally-stored arrays and lookup functions. This makes it easy fordeveloppers adding new modes to forget modifying phylib and phylinkaccordingly.However, the link_mode_params array in net/ethtool/common.c is fairlyinefficient to search through, as it isn't sorted in any manner. Phyliband phylink perform a lot of lookup operations, mostly to filter modesby speed and/or duplex.We therefore introduce the link_caps private array in phy_caps.c, thatindexes linkmodes in a more efficient manner. Each element associated atuple to a bitfield of all the linkmodes runs at thesespeed/duplex.We end-up with an array that's fairly short, easily addressable and thatit optimised for the typical use-cases of phylib/phylink.That array is initialized at the same time as phylib. As thelink_mode_params array is part of the net stack, which phylink dependson, it should always be accessible from phylib.Signed-off-by: Maxime Chevallier Link: https://patch.msgid.link/20250307173611.129125-3-maxime.chevallier@bootlin.comSigned-off-by: Paolo Abeni List of files: /linux/drivers/net/phy/Makefile
