Mateusz Polchlopek says: 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. --- IWL: https://lore.kernel.org/intel-wired-lan/20241106173731.4272-1-mateusz.polchlopek@intel.com/ The following are changes since commit 7a7e0197133d18cfd9931e7d3a842d0f5730223f: Merge git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net and are available in the git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue 100GbE 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 (3): libeth: move idpf_rx_csum_decoded and idpf_rx_extracted iavf: define Rx descriptors as qwords iavf: Implement checking DD desc field Simei Su (1): ice: support Rx timestamp on flex descriptor drivers/net/ethernet/intel/Kconfig | 1 + drivers/net/ethernet/intel/iavf/Makefile | 2 + drivers/net/ethernet/intel/iavf/iavf.h | 35 +- drivers/net/ethernet/intel/iavf/iavf_main.c | 228 +++++++- drivers/net/ethernet/intel/iavf/iavf_ptp.c | 485 ++++++++++++++++++ drivers/net/ethernet/intel/iavf/iavf_ptp.h | 47 ++ drivers/net/ethernet/intel/iavf/iavf_trace.h | 6 +- drivers/net/ethernet/intel/iavf/iavf_txrx.c | 433 ++++++++++++---- drivers/net/ethernet/intel/iavf/iavf_txrx.h | 24 +- drivers/net/ethernet/intel/iavf/iavf_type.h | 239 ++++----- drivers/net/ethernet/intel/iavf/iavf_types.h | 34 ++ .../net/ethernet/intel/iavf/iavf_virtchnl.c | 203 ++++++++ drivers/net/ethernet/intel/ice/ice_base.c | 3 - drivers/net/ethernet/intel/ice/ice_lib.c | 5 +- drivers/net/ethernet/intel/ice/ice_ptp.c | 4 +- drivers/net/ethernet/intel/ice/ice_ptp.h | 8 + drivers/net/ethernet/intel/ice/ice_vf_lib.h | 3 + drivers/net/ethernet/intel/ice/ice_virtchnl.c | 80 ++- drivers/net/ethernet/intel/ice/ice_virtchnl.h | 6 + .../intel/ice/ice_virtchnl_allowlist.c | 7 + .../ethernet/intel/idpf/idpf_singleq_txrx.c | 51 +- drivers/net/ethernet/intel/idpf/idpf_txrx.c | 16 +- drivers/net/ethernet/intel/idpf/idpf_txrx.h | 19 - include/linux/avf/virtchnl.h | 135 ++++- include/net/libeth/rx.h | 47 ++ 25 files changed, 1790 insertions(+), 331 deletions(-) create mode 100644 drivers/net/ethernet/intel/iavf/iavf_ptp.c create mode 100644 drivers/net/ethernet/intel/iavf/iavf_ptp.h create mode 100644 drivers/net/ethernet/intel/iavf/iavf_types.h
