2020-02-19phy: avoid unnecessary link-up delay in polling modePetr Oros
commit 93c0970493c71f ("net: phy: consider latched link-down status in polling mode") removed double-read of latched link-state register for polling mode from genphy_update_link(). This added extra ~1s delay into sequence link down->up. Following scenario: - After boot link goes up - phy_start() is called triggering an aneg restart, hence link goes down and link-down info is latched. - After aneg has finished link goes up. In phy_state_machine is checked link state but it is latched "link is down". The state machine is scheduled after one second and there is detected "link is up". This extra delay can be avoided when we keep link-state register double read in case when link was down previously. With this solution we don't miss a link-down event in polling mode and link-up is faster. Details about this quirky behavior on Realtek phy: Without patch: T0: aneg is started, link goes down, link-down status is latched T0+3s: state machine runs, up-to-date link-down is read T0+4s: state machine runs, aneg is finished (BMSR_ANEGCOMPLETE==1), here i read link-down (BMSR_LSTATUS==0), T0+5s: state machine runs, aneg is finished (BMSR_ANEGCOMPLETE==1), up-to-date link-up is read (BMSR_LSTATUS==1), phydev->link goes up, state change PHY_NOLINK to PHY_RUNNING With patch: T0: aneg is started, link goes down, link-down status is latched T0+3s: state machine runs, up-to-date link-down is read T0+4s: state machine runs, aneg is finished (BMSR_ANEGCOMPLETE==1), first BMSR read: BMSR_ANEGCOMPLETE==1 and BMSR_LSTATUS==0, second BMSR read: BMSR_ANEGCOMPLETE==1 and BMSR_LSTATUS==1, phydev->link goes up, state change PHY_NOLINK to PHY_RUNNING Signed-off-by: Petr Oros <poros@redhat.com> Reviewed-by: Heiner Kallweit <hkallweit1@gmail.com> Signed-off-by: David S.

2019-10-16net: phy: Fix "link partner" information disappear issueYonglong Liu
Some drivers just call phy_ethtool_ksettings_set() to set the links, for those phy drivers that use genphy_read_status(), if autoneg is on, and the link is up, than execute "ethtool -s ethx autoneg on" will cause "link partner" information disappear. The call trace is phy_ethtool_ksettings_set()->phy_start_aneg() ->linkmode_zero(phydev->lp_advertising)->genphy_read_status(), the link didn't change, so genphy_read_status() just return, and phydev->lp_advertising is zero now. This patch moves the clear operation of lp_advertising from phy_start_aneg() to genphy_read_lpa()/genphy_c45_read_lpa(), and if autoneg on and autoneg not complete, just clear what the generic functions care about.

2019-08-27Add genphy_c45_config_aneg() function to phy-c45.cMarco Hartmann
Commit 34786005eca3 ("net: phy: prevent PHYs w/o Clause 22 regs from calling genphy_config_aneg") introduced a check that aborts phy_config_aneg() if the phy is a C45 phy. This causes phy_state_machine() to call phy_error() so that the phy ends up in PHY_HALTED state. Instead of returning -EOPNOTSUPP, call genphy_c45_config_aneg() (analogous to the C22 case) so that the state machine can run correctly. genphy_c45_config_aneg() closely resembles mv3310_config_aneg() in drivers/net/phy/marvell10g.c, excluding vendor specific configurations for 1000BaseT.

2019-08-13net: phy: consider AN_RESTART status when reading link statusHeiner Kallweit
After configuring and restarting aneg we immediately try to read the link status. On some systems the PHY may not yet have cleared the "aneg complete" and "link up" bits, resulting in a false link-up signal. See [0] for a report. Clause 22 and 45 both require the PHY to keep the AN_RESTART bit set until the PHY actually starts auto-negotiation. Let's consider this in the generic functions for reading link status. The commit marked as fixed is the first one where the patch applies cleanly.

The current code reports a link as up if all devices (except a few blacklisted ones) report the link as up. This breaks Aquantia AQCS109 for lower speeds because on this PHY the PCS link status reflects a 10G link only. For Marvell there's a similar issue, therefore PHYXS device isn't checked. There may be more PHYs where depending on the mode the link status of only selected devices is relevant. For now it seems to be sufficient to check the link status of the PMAPMD device only. Leave the loop in the code to be prepared in case we have to add functionality to check more than one device, depending on the mode. Successfully tested on a board with an AQCS109.

2019-02-08net: phy: consider latched link-down status in polling modeHeiner Kallweit
The link status value latches link-down events. To get the current status we read the register twice in genphy_update_link(). There's a potential risk that we miss a link-down event in polling mode. This may cause issues if the user e.g. connects his machine to a different network. On the other hand reading the latched value may cause issues in interrupt mode. Following scenario: - After boot link goes up - phy_start() is called triggering an aneg restart, hence link goes down and link-down info is latched. - After aneg has finished link goes up and triggers an interrupt. Interrupt handler reads link status, means it reads the latched "link is down" info. But there won't be another interrupt as long as link stays up, therefore phylib will never recognize that link is up. Deal with both scenarios by reading the register twice in interrupt mode only.
