It is because device returns free-running timestamp, and the conversion from free-running to real-time is performed in the user space. This series fixes it, by returning real-time timestamp. ==================== * mlx5_realtime_ts: RDMA/mlx5: Support real-time timestamp directly from the device RDMA/mlx5: Refactor get_ts_format functions to simplify code Signed-off-by: Jason Gunthorpe <jgg@nvidia.com> 2021-06-22T17:23:50Z Aharon Landau aharonl@nvidia.com 2021-06-16T07:57:39Z urn:sha1:336529518e9724d4cecabc622e57bcdce02e7c61 Currently, if the user asks for a real-time timestamp, the device will return a free-running one, and the timestamp will be translated to real-time in the user-space. When the device supports only real-time timestamp and not free-running, the creation of the QP will fail even though the user needs supported the real-time one. To prevent this, we will return the real-time timestamp directly from the device.

The irdma module replaces the legacy i40iw module for X722 and extends the ABI already defined for i40iw. It is backward compatible with legacy X722 rdma-core provider (libi40iw). X722 and E810 are PCI network devices that are RDMA capable. The RDMA block of this parent device is represented via an auxiliary device exported to 'irdma' using the core auxiliary bus infrastructure recently added for 5.11 kernel. The parent PCI netdev drivers 'i40e' and 'ice' register auxiliary RDMA devices with private data/ops encapsulated that bind to auxiliary drivers registered in irdma module. Currently, default is RoCEv2 for E810. Runtime support for protocol switch to iWARP will be made available via devlink in a future patch. ==================== Link: https://lore.kernel.org/r/20210602205138.889-1-shiraz.saleem@intel.com Signed-off-by: Jason Gunthorpe <jgg@nvidia.com> * branch 'irdma': RDMA/irdma: Update MAINTAINERS file RDMA/irdma: Add irdma Kconfig/Makefile and remove i40iw RDMA/irdma: Add ABI definitions RDMA/irdma: Add dynamic tracing for CM RDMA/irdma: Add miscellaneous utility definitions RDMA/irdma: Add user/kernel shared libraries RDMA/irdma: Add RoCEv2 UD OP support RDMA/irdma: Implement device supported verb APIs RDMA/irdma: Add PBLE resource manager RDMA/irdma: Add connection manager RDMA/irdma: Add QoS definitions RDMA/irdma: Add privileged UDA queue implementation RDMA/irdma: Add HMC backing store setup functions RDMA/irdma: Implement HW Admin Queue OPs RDMA/irdma: Implement device initialization definitions RDMA/irdma: Register auxiliary driver and implement private channel OPs i40e: Register auxiliary devices to provide RDMA i40e: Prep i40e header for aux bus conversion ice: Register auxiliary device to provide RDMA ice: Implement iidc operations ice: Initialize RDMA support iidc: Introduce iidc.h i40e: Replace one-element array with flexible-array member 2021-06-02T23:06:36Z Shiraz Saleem shiraz.saleem@intel.com 2021-06-02T20:51:37Z urn:sha1:fa0cf568fd76550c1ddb806c03a65a1a4a1ea909 Add Kconfig and Makefile to build irdma driver.
