Get rid of these functions by using timestamp configuration in parameter. This also allow to move on to kernel_hwtstamp_config and be similar to net devices using the new ndo_hwstamp_get/set. This adds the possibility to manipulate the timestamp configuration from the kernel which was not possible with the copy_from/to_user.

Now that ifreq has been removed from the hwstamp callback parameters it seems more logical to not go through the phy_mii_ioctl function and pass directly kernel_hwtstamp_config parameter to the hwtstamp callback. Lets do the same for __phy_hwtstamp_get function and return directly EOPNOTSUPP as SIOCGHWTSTAMP is not supported for now for the PHYs.

In preparation for making the choice selectable, expose both the current and available layers via ethtool. In accordance with the kernel implementation as it stands, the current layer will always read as "phy" when a PHY time stamping device is present. Future patches will allow changing the current layer administratively. Signed-off-by: Kory Maincent --- Changes in v2: - Move the introduction of selected_timestamping_layer variable in next patch. Changes in v3: - Move on to ethtool instead of syfs Changes in v4: - Move on to netlink ethtool instead of ioctl. I am not familiar with netlink so there might be some code that does not follow the good code practice. Changes in v5: - Rename timestamping layers. - Set a default value of ts_layer in __ethtool_get_ts_info function. - Separate TS_GET and TS_LIST_GET ethtool command in two separate patches. - Update documentation. --- Documentation/networking/ethtool-netlink.rst | 23 ++++++ include/uapi/linux/ethtool_netlink.h | 14 ++++ include/uapi/linux/net_tstamp.h | 14 ++++ net/ethtool/Makefile | 2 +- net/ethtool/common.h | 1 + net/ethtool/netlink.c | 10 +++ net/ethtool/netlink.h | 2 + net/ethtool/ts.c | 78 ++++++++++++++++++++ 8 files changed, 143 insertions(+), 1 deletion(-) create mode 100644 net/ethtool/ts.c diff --git a/Documentation/networking/ethtool-netlink.rst b/Documentation/networking/ethtool-netlink.rst index 2540c70952ff..644b3b764044 100644 --- a/Documentation/networking/ethtool-netlink.rst +++ b/Documentation/networking/ethtool-netlink.rst @@ -225,6 +225,7 @@ Userspace to kernel: ``ETHTOOL_MSG_RSS_GET`` get RSS settings ``ETHTOOL_MSG_MM_GET`` get MAC merge layer state ``ETHTOOL_MSG_MM_SET`` set MAC merge layer parameters + ``ETHTOOL_MSG_TS_GET`` get current timestamping ===================================== ================================= Kernel to userspace: @@ -268,6 +269,7 @@ Kernel to userspace: ``ETHTOOL_MSG_PSE_GET_REPLY`` PSE parameters ``ETHTOOL_MSG_RSS_GET_REPLY`` RSS settings ``ETHTOOL_MSG_MM_GET_REPLY`` MAC merge layer status + ``ETHTOOL_MSG_TS_GET_REPLY`` current timestamping ======================================== ================================= ``GET`` requests are sent by userspace applications to retrieve device @@ -1994,6 +1996,26 @@ The attributes are propagated to the driver through the following structure: .. kernel-doc:: include/linux/ethtool.h :identifiers: ethtool_mm_cfg +TS_GET +====== + +Gets current timestamping. + +Request contents: + + ================================= ====== ==================== + ``ETHTOOL_A_TS_HEADER`` nested request header + ================================= ====== ==================== + +Kernel response contents: + + ======================= ====== ============================== + ``ETHTOOL_A_TS_HEADER`` nested reply header + ``ETHTOOL_A_TS_LAYER`` u32 current timestamping + ======================= ====== ============================== + +This command get the current timestamp layer. + Request translation =================== @@ -2100,4 +2122,5 @@ are netlink only. n/a ``ETHTOOL_MSG_PLCA_GET_STATUS`` n/a ``ETHTOOL_MSG_MM_GET`` n/a ``ETHTOOL_MSG_MM_SET`` + n/a ``ETHTOOL_MSG_TS_GET`` =================================== ===================================== diff --git a/include/uapi/linux/ethtool_netlink.h b/include/uapi/linux/ethtool_netlink.h index 73e2c10dc2cc..cb51136328cf 100644 --- a/include/uapi/linux/ethtool_netlink.h +++ b/include/uapi/linux/ethtool_netlink.h @@ -57,6 +57,7 @@ enum { ETHTOOL_MSG_PLCA_GET_STATUS, ETHTOOL_MSG_MM_GET, ETHTOOL_MSG_MM_SET, + ETHTOOL_MSG_TS_GET, /* add new constants above here */ __ETHTOOL_MSG_USER_CNT, @@ -109,6 +110,7 @@ enum { ETHTOOL_MSG_PLCA_NTF, ETHTOOL_MSG_MM_GET_REPLY, ETHTOOL_MSG_MM_NTF, + ETHTOOL_MSG_TS_GET_REPLY, /* add new constants above here */ __ETHTOOL_MSG_KERNEL_CNT, @@ -975,6 +977,18 @@ enum { ETHTOOL_A_MM_MAX = (__ETHTOOL_A_MM_CNT - 1) };

Indeed the PHY is closer to the wire therefore theoretically it have 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 board are not very widespread. For not breaking the compatibility I introduce an allowlist to reference all current PHYs that support time stamping and let them keep the old API behavior. The phy_set_timestamp function is called at each call of phy_attach_direct. In case of MAC driver using phylink this function is called when the interface is turned up. Then if the interface goes down and up again the last choice of timestamp will be overwritten by the default choice. A solution could be to cache the timestamp status but it can bring other issues. In case of SFP, if we change the module, it doesn't make sense to blindly re-set the timestamp back to PHY, if the new module has a PHY with mediocre timestamping capabilities.

Signed-off-by: Kory Maincent --- Changes in v2: - Move selected_timestamping_layer introduction in this patch. - Replace strmcmp by sysfs_streq. - Use the PHY timestamp only if available. Changes in v3: - Add a devicetree binding to select the preferred timestamp - Replace the way to select timestamp through ethtool instead of sysfs You can test it with the ethtool source on branch feature_ptp of: https://github.com/kmaincent/ethtool Changes in v4: - Change the API to select MAC default time stamping instead of the PHY. - Add a whitelist to no break the old timestamp PHY default preferences for current PHY. - Replace the ethtool ioctl by netlink. - Add a netdev notifier to allow network device to create trap on PTP packets. Not tested as it need to change the lan966x driver that implement packet traps. I will do after the hwtstamp management change to NDOs. Changes in v5: - Remove the netdev notifier added in v4. - Extract the default timestamp API change in another patch. --- Documentation/networking/ethtool-netlink.rst | 17 +++++ include/uapi/linux/ethtool_netlink.h | 1 + net/ethtool/netlink.c | 8 +++ net/ethtool/netlink.h | 1 + net/ethtool/ts.c | 66 ++++++++++++++++++++ 5 files changed, 93 insertions(+) diff --git a/Documentation/networking/ethtool-netlink.rst b/Documentation/networking/ethtool-netlink.rst index 963a5aacac8d..eb7f8592986b 100644 --- a/Documentation/networking/ethtool-netlink.rst +++ b/Documentation/networking/ethtool-netlink.rst @@ -227,6 +227,7 @@ Userspace to kernel: ``ETHTOOL_MSG_MM_SET`` set MAC merge layer parameters ``ETHTOOL_MSG_TS_GET`` get current timestamping ``ETHTOOL_MSG_TS_LIST_GET`` list available timestampings + ``ETHTOOL_MSG_TS_SET`` set current timestamping ===================================== ================================= Kernel to userspace: @@ -2038,6 +2039,21 @@ Kernel response contents: This command lists all the possible timestamp layer available. +TS_SET +====== + +Modify the selected timestamping. + +Request contents: + + ======================= ====== =================== + ``ETHTOOL_A_TS_HEADER`` nested reply header + ``ETHTOOL_A_TS_LAYER`` u32 timestamping + ======================= ====== =================== + +This command set the timestamping with one that should be listed by the +TSLIST_GET command. + Request translation =================== @@ -2146,4 +2162,5 @@ are netlink only. n/a ``ETHTOOL_MSG_MM_SET`` n/a ``ETHTOOL_MSG_TSLIST_GET`` n/a ``ETHTOOL_MSG_TS_GET`` + n/a ``ETHTOOL_MSG_TS_SET`` =================================== ===================================== diff --git a/include/uapi/linux/ethtool_netlink.h b/include/uapi/linux/ethtool_netlink.h index 62b885d44d06..df6c4fcc62c1 100644 --- a/include/uapi/linux/ethtool_netlink.h +++ b/include/uapi/linux/ethtool_netlink.h @@ -59,6 +59,7 @@ enum { ETHTOOL_MSG_MM_SET, ETHTOOL_MSG_TS_GET, ETHTOOL_MSG_TS_LIST_GET, + ETHTOOL_MSG_TS_SET, /* add new constants above here */ __ETHTOOL_MSG_USER_CNT, diff --git a/net/ethtool/netlink.c b/net/ethtool/netlink.c index 842c9db1531f..8322bf71f80d 100644 --- a/net/ethtool/netlink.c +++ b/net/ethtool/netlink.c @@ -308,6 +308,7 @@ ethnl_default_requests[__ETHTOOL_MSG_USER_CNT] = { [ETHTOOL_MSG_MM_SET] = ðnl_mm_request_ops, [ETHTOOL_MSG_TS_GET] = ðnl_ts_request_ops, [ETHTOOL_MSG_TS_LIST_GET] = ðnl_ts_list_request_ops, + [ETHTOOL_MSG_TS_SET] = ðnl_ts_request_ops, };
