Date: Tue, 4 Jun 2024 09:13:48 -0400 Message-Id: <20240604131400.13655-1-mateusz.polchlopek@intel.com> X-Mailer: git-send-email 2.38.1 Precedence: bulk X-Mailing-List: netdev@vger.kernel.org List-Id: List-Subscribe: List-Unsubscribe: MIME-Version: 1.0 Initially, during VF creation it registers the PTP clock in the system and negotiates with PF it's capabilities. In the meantime the PF enables the Flexible Descriptor for VF. Only this type of descriptor allows to receive Rx timestamps. Enabling virtual clock would be possible, though it would probably perform poorly due to the lack of direct time access. Enable timestamping should be done using userspace tools, e.g. hwstamp_ctl -i $VF -r 14 In order to report the timestamps to userspace, the VF extends timestamp to 40b. To support this feature the flexible descriptors and PTP part in iavf driver have been introduced. --- v7: - changed .ndo_eth_ioctl to .ndo_hwtstamp_get and .ndo_hwtstamp_set (according to Kuba's suggestion) - patch 11 v6: - reordered tags - added RB tags where applicable - removed redundant instructions in ifs - patch 4 and patch 5 - changed teardown to LIFO, adapter->ptp.initialized = false moved to the top of function - patch 6 - changed cpu-endianess for testing - patch 9 - aligned to libeth changes - patch 9 https://lore.kernel.org/netdev/20240528112301.5374-1-mateusz.polchlopek@intel.com/ v5: - fixed all new issues generated by this series in kernel-doc https://lore.kernel.org/netdev/20240418052500.50678-1-mateusz.polchlopek@intel.com/ v4: - fixed duplicated argument in iavf_virtchnl.c reported by coccicheck https://lore.kernel.org/netdev/20240410121706.6223-1-mateusz.polchlopek@intel.com/ v3: - added RB in commit 6 - removed inline keyword in commit 9 - fixed sparse issues in commit 9 and commit 10 - used GENMASK_ULL when possible in commit 9 https://lore.kernel.org/netdev/20240403131927.87021-1-mateusz.polchlopek@intel.com/ v2: - fixed warning related to wrong specifier to dev_err_once in commit 7 - fixed warnings related to unused variables in commit 9 https://lore.kernel.org/netdev/20240327132543.15923-1-mateusz.polchlopek@intel.com/ v1: - initial series https://lore.kernel.org/netdev/20240326115116.10040-1-mateusz.polchlopek@intel.com/ --- Jacob Keller (10): virtchnl: add support for enabling PTP on iAVF virtchnl: add enumeration for the rxdid format iavf: add support for negotiating flexible RXDID format iavf: negotiate PTP capabilities iavf: add initial framework for registering PTP clock iavf: add support for indirect access to PHC time iavf: periodically cache PHC time iavf: refactor iavf_clean_rx_irq to support legacy and flex descriptors iavf: handle set and get timestamps ops iavf: add support for Rx timestamps to hotpath Mateusz Polchlopek (1): iavf: Implement checking DD desc field Simei Su (1): ice: support Rx timestamp on flex descriptor drivers/net/ethernet/intel/iavf/Makefile | 3 +- drivers/net/ethernet/intel/iavf/iavf.h | 33 +- drivers/net/ethernet/intel/iavf/iavf_main.c | 238 +++++++- drivers/net/ethernet/intel/iavf/iavf_ptp.c | 543 ++++++++++++++++++ drivers/net/ethernet/intel/iavf/iavf_ptp.h | 49 ++ drivers/net/ethernet/intel/iavf/iavf_txrx.c | 425 +++++++++++--- drivers/net/ethernet/intel/iavf/iavf_txrx.h | 26 +- drivers/net/ethernet/intel/iavf/iavf_type.h | 148 +++-- .../net/ethernet/intel/iavf/iavf_virtchnl.c | 238 ++++++++ drivers/net/ethernet/intel/ice/ice_base.c | 3 - drivers/net/ethernet/intel/ice/ice_ptp.c | 4 +- drivers/net/ethernet/intel/ice/ice_ptp.h | 2 + drivers/net/ethernet/intel/ice/ice_vf_lib.h | 2 + drivers/net/ethernet/intel/ice/ice_virtchnl.c | 86 ++- drivers/net/ethernet/intel/ice/ice_virtchnl.h | 2 + .../intel/ice/ice_virtchnl_allowlist.c | 6 + include/linux/avf/virtchnl.h | 127 +++- 17 files changed, 1776 insertions(+), 159 deletions(-) create mode 100644 drivers/net/ethernet/intel/iavf/iavf_ptp.c create mode 100644 drivers/net/ethernet/intel/iavf/iavf_ptp.h
