Up until now, there was no way to let the user select the hardware PTP provider at which time stamping occurs. The stack assumed that PHY time stamping is always preferred, but some MAC/PHY combinations were buggy. This series updates the default MAC/PHY default timestamping and aims to allow the user to select the desired hwtstamp provider administratively. Changes in v14: - Add back an EXPORT_SYMBOL() missing. - Link to v13: https://lore.kernel.org/r/20240529-feature_ptp_netnext-v13-0-6eda4d40fa4f@bootlin.com Changes in v13: - Add PTP builtin code to fix build errors when building PTP as a module. - Fix error spotted by smatch and sparse. - Link to v12: https://lore.kernel.org/r/20240430-feature_ptp_netnext-v12-0-2c5f24b6a914@bootlin.com Changes in v12: - Add missing return description in the kdoc. - Fix few nit. - Link to v11: https://lore.kernel.org/r/20240422-feature_ptp_netnext-v11-0-f14441f2a1d8@bootlin.com Changes in v11: - Add netlink examples. - Remove a change of my out of tree marvell_ptp patch in the patch series. - Remove useless extern. - Link to v10: https://lore.kernel.org/r/20240409-feature_ptp_netnext-v10-0-0fa2ea5c89a9@bootlin.com Changes in v10: - Move declarations to net/core/dev.h instead of netdevice.h - Add netlink documentation. - Add ETHTOOL_A_TSINFO_GHWTSTAMP netlink attributes instead of a bit in ETHTOOL_A_TSINFO_TIMESTAMPING bitset. - Send "Move from simple ida to xarray" patch standalone. - Add tsinfo ntf command. - Add rcu_lock protection mechanism to avoid memory leak. - Fixed doc and kdoc issue. - Link to v9: https://lore.kernel.org/r/20240226-feature_ptp_netnext-v9-0-455611549f21@bootlin.com Changes in v9: - Remove the RFC prefix. - Correct few NIT fixes. - Link to v8: https://lore.kernel.org/r/20240216-feature_ptp_netnext-v8-0-510f42f444fb@bootlin.com Changes in v8: - Drop the 6 first patch as they are now merged. - Change the full implementation to not be based on the hwtstamp layer (MAC/PHY) but on the hwtstamp provider which mean a ptp clock and a phc qualifier. - Made some patch to prepare the new implementation. - Expand netlink tsinfo instead of a new ts command for new hwtstamp configuration uAPI and for dumping tsinfo of specific hwtstamp provider. - Link to v7: https://lore.kernel.org/r/20231114-feature_ptp_netnext-v7-0-472e77951e40@bootlin.com Changes in v7: - Fix a temporary build error. - Link to v6: https://lore.kernel.org/r/20231019-feature_ptp_netnext-v6-0-71affc27b0e5@bootlin.com Changes in v6: - Few fixes from the reviews. - Replace the allowlist to default_timestamp flag to know which phy is using old API behavior. - Rename the timestamping layer enum values. - Move to a simple enum instead of the mix between enum and bitfield. - Update ts_info and ts-set in software timestamping case. Changes in v5: - Update to ndo_hwstamp_get/set. This bring several new patches. - Add few patches to make the glue. - Convert macb to ndo_hwstamp_get/set. - Add netlink specs description of new ethtool commands. - Removed netdev notifier. - Split the patches that expose the timestamping to userspace to separate the core and ethtool development. - Add description of software timestamping. - Convert PHYs hwtstamp callback to use kernel_hwtstamp_config. Changes in v4: - Move on to ethtool netlink instead of ioctl. - Add a netdev notifier to allow packet trapping by the MAC in case of PHY time stamping. - Add a PHY whitelist to not break the old PHY default time-stamping preference API. Changes in v3: - Expose the PTP choice to ethtool instead of sysfs. You can test it with the ethtool source on branch feature_ptp of: https://github.com/kmaincent/ethtool - Added a devicetree binding to select the preferred timestamp. Changes in v2: - Move selected_timestamping_layer variable of the concerned patch. - Use sysfs_streq instead of strmcmp. - Use the PHY timestamp only if available.
