Indeed the PHY is closer to the wire therefore theoretically it has less delay than the MAC timestamping but the reality is different. Due to lower time stamping clock frequency, latency in the MDIO bus and no PHC hardware synchronization between different PHY, the PHY PTP is often less precise than the MAC. The exception is for PHY designed specially for PTP case but these devices are not very widespread. For not breaking the compatibility default_timestamp flag has been introduced in phy_device that is set by the phy driver to know we are using the old API behavior. Reviewed-by: Rahul Rameshbabu Signed-off-by: Kory Maincent --- Changes in v5: - Extract the API change in this patch. - Rename whitelist to allowlist. - Set NETDEV_TIMESTAMPING in register_netdevice function. - Add software timestamping case description in ts_info. Change in v6: - Replace the allowlist phy with a default_timestamp flag to know which phy is using old API behavior. - Fix dereferenced of a possible null pointer. - Follow timestamping layer naming update. - Update timestamp default set between MAC and software. - Update ts_info returned in case of software timestamping. Change in v8: - Reform the implementation to use a simple phy_is_default_hwtstamp helper instead of saving the hwtstamp in the net_device struct. Change in v9: - Update few nit following the review. --- drivers/net/phy/bcm-phy-ptp.c | 3 +++ drivers/net/phy/dp83640.c | 2 ++ drivers/net/phy/micrel.c | 6 ++++++ drivers/net/phy/mscc/mscc_ptp.c | 3 +++ drivers/net/phy/nxp-c45-tja11xx.c | 3 +++ include/linux/phy.h | 17 +++++++++++++++++ net/core/dev_ioctl.c | 8 +++----- net/core/timestamping.c | 5 +++-- net/ethtool/common.c | 2 +- 9 files changed, 41 insertions(+), 8 deletions(-) diff --git a/drivers/net/phy/bcm-phy-ptp.c b/drivers/net/phy/bcm-phy-ptp.c index 617d384d4551..d3e825c951ee 100644 --- a/drivers/net/phy/bcm-phy-ptp.c +++ b/drivers/net/phy/bcm-phy-ptp.c @@ -931,6 +931,9 @@ struct bcm_ptp_private *bcm_ptp_probe(struct phy_device *phydev) return ERR_CAST(clock);

It would be good if new kernel code already started operating on an extensible kernel variant of that structure, similar in concept to struct kernel_hwtstamp_config vs struct hwtstamp_config. Since struct ethtool_ts_info is in include/uapi/linux/ethtool.h, here we introduce the kernel-only structure in include/linux/ethtool.h. The manual copy is then made in the function called by ETHTOOL_GET_TS_INFO.

Add a hwtstamp provider description within the netdev structure to be able to select the hwtstamp we want too use. By default we use the old API that does not support hwtstamp selectability which mean the hwtstamp ptp_clock pointer is unset.

It is the only driver using the mock driver to register a ptp clock. Convert the mock driver to the new API.
