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. Change in v12: - Add missing return description in the kdoc. --- 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 | 19 +++++++++++++++++++ net/core/dev_ioctl.c | 8 +++----- net/core/timestamping.c | 5 +++-- net/ethtool/common.c | 2 +- 9 files changed, 43 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.

Additionally, introduce helpers for registering specific phydev or netdev PTP clocks, retrieving PTP clock information such as hwtstamp source or phydev/netdev pointers, and obtaining the ptp_clock structure from the phc index. These helpers are added to a new ptp_clock_consumer.c file, built as builtin. This is necessary because these helpers will be called by ethtool or net timestamping, which are builtin code. Signed-off-by: Kory Maincent --- Change in v8: - New patch. Change in v10: - Add get and put function to avoid unregistering a ptp clock object used. - Fix kdoc issues. Change in v11: - Remove useless extern. Change in v12: - Add missing return description in the kdoc. Change in v13: - Remove a semicolon which bring errors while not building PTP driver. - Remove few useless EXPORT_SYMBOL(). - Separate PTP consumer symbole which are builtin from PTP provider. Change in v14: - Add back missing EXPORT_SYMBOL(). --- drivers/ptp/Makefile | 5 ++ drivers/ptp/ptp_clock.c | 33 ++++++++++- drivers/ptp/ptp_clock_consumer.c | 100 +++++++++++++++++++++++++++++++ drivers/ptp/ptp_private.h | 7 +++ include/linux/ptp_clock_kernel.h | 125 +++++++++++++++++++++++++++++++++++++++ 5 files changed, 269 insertions(+), 1 deletion(-) diff --git a/drivers/ptp/Makefile b/drivers/ptp/Makefile index 68bf02078053..9d7226b995cf 100644 --- a/drivers/ptp/Makefile +++ b/drivers/ptp/Makefile @@ -3,6 +3,11 @@ # Makefile for PTP 1588 clock support. # +ifdef CONFIG_PTP_1588_CLOCK +# The ptp_clock consumer is built-in whenever PTP_1588_CLOCK is built-in +# or module +obj-y := ptp_clock_consumer.o +endif ptp-y := ptp_clock.o ptp_chardev.o ptp_sysfs.o ptp_vclock.o ptp_kvm-$(CONFIG_X86) := ptp_kvm_x86.o ptp_kvm_common.o ptp_kvm-$(CONFIG_HAVE_ARM_SMCCC) := ptp_kvm_arm.o ptp_kvm_common.o diff --git a/drivers/ptp/ptp_clock.c b/drivers/ptp/ptp_clock.c index c56cd0f63909..593b5c906314 100644 --- a/drivers/ptp/ptp_clock.c +++ b/drivers/ptp/ptp_clock.c @@ -34,7 +34,6 @@ const struct class ptp_class = { static dev_t ptp_devt;

Add a hwtstamp provider description within the netdev structure to allow saving the hwtstamp we want to use. This prepares for future support of an ethtool netlink command to select the desired hwtstamp provider. By default, the old API that does not support hwtstamp selectability is used, meaning the hwtstamp ptp_clock pointer is unset. Signed-off-by: Kory Maincent --- Change in v8: - New patch Change in v10: - Set hwtstamp in netdevice as a pointer for future use of rcu lock. - Fix a nit in teh order of setting phydev pointer. - Add a missing kdoc description. Change in v13: - Remove an include from netdevices.h. Change in v16: - Import the part of the patch 12 which belong to the hwtstamp provider selectability of net core. --- drivers/net/phy/phy_device.c | 11 +++++++++ drivers/ptp/ptp_clock_consumer.c | 10 ++++++++ include/linux/net_tstamp.h | 18 +++++++++++++++ include/linux/netdevice.h | 5 ++++ include/linux/ptp_clock_kernel.h | 10 ++++++++ include/uapi/linux/net_tstamp.h | 11 +++++++++ net/core/dev_ioctl.c | 43 ++++++++++++++++++++++++++++++++-- net/core/timestamping.c | 50 ++++++++++++++++++++++++++++++++++++---- 8 files changed, 151 insertions(+), 7 deletions(-) diff --git a/drivers/net/phy/phy_device.c b/drivers/net/phy/phy_device.c index 70b07e621fb2..57a9943bb1c1 100644 --- a/drivers/net/phy/phy_device.c +++ b/drivers/net/phy/phy_device.c @@ -31,6 +31,7 @@ #include #include #include +#include #include #include #include @@ -1936,6 +1937,16 @@ void phy_detach(struct phy_device *phydev) phy_suspend(phydev);

Add simultaneously a tsconfig command to be able to get and set hwtstamp configuration for a specified phc provider.
