The free-running format provides some opaque values captured from internal clock counter clocked by some independent oscillator. The free-running frequency is not pre-defined and should be queried from the NIC. The real-time timestamps are presented in nanoseconds and captured from the dedicated UTC counter, that can be adjusted on the fly and might be synchronized with some external master clock. Depending on the version and configuration the hardware might support either FR or RT timestamps, or both in the same time on per queue basis. Since firmware version xx.30.0256 the timestamp format can be configured via fields in the queue context at the object creation time. For the compatibility reasons the default zero value configures timestamps with free-running format. The NIC ConnectX-5 and earlier ones support the free-running format only. Since ConnectX-6 both formats might be supported and configured. The default zero value (specified in the non-defined yet timestamp format context field) causes the queue creation failure (rejected by firmware) if the NIC is configured to real-time timestamp format. Hence, it is crucial to check whether firmware/hardware supports timestamp formats and configure queues accordingly, and this patchset also must be provided for stable DPDK releases. Compatibility affected (without this patchset) summary: - ConnectX-6DX or BlueField 2 - real-time format is configured in NV settings - firmware is xx.30.1000 or higher Viacheslav Ovsiienko (5): common/mlx5: add timestamp format support to DevX net/mlx5: add timestamp format support vdpa/mlx5: add timestamp format support regex/mlx5: add timestamp format support compress/mlx5: add timestamp format support drivers/common/mlx5/mlx5_devx_cmds.c | 35 ++++++++++++++-- drivers/common/mlx5/mlx5_devx_cmds.h | 7 ++++ drivers/common/mlx5/mlx5_prm.h | 55 +++++++++++++++++++++++-- drivers/compress/mlx5/mlx5_compress.c | 3 ++ drivers/net/mlx5/linux/mlx5_os.c | 3 ++ drivers/net/mlx5/mlx5.h | 3 ++ drivers/net/mlx5/mlx5_devx.c | 2 +- drivers/net/mlx5/mlx5_flow_age.c | 7 +++- drivers/net/mlx5/mlx5_txpp.c | 2 + drivers/net/mlx5/windows/mlx5_os.c | 3 ++ drivers/regex/mlx5/mlx5_regex.c | 1 + drivers/regex/mlx5/mlx5_regex.h | 1 + drivers/regex/mlx5/mlx5_regex_control.c | 1 + drivers/vdpa/mlx5/mlx5_vdpa.c | 1 + drivers/vdpa/mlx5/mlx5_vdpa.h | 1 + drivers/vdpa/mlx5/mlx5_vdpa_event.c | 2 + 16 files changed, 117 insertions(+), 10 deletions(-) -- v1: https://inbox.dpdk.org/dev/20210307100251.22538-1-viacheslavo@nvidia.com/ v2: - remove non needed settings for hairpins - the unified inline routine to set timestamp format - typos and rewording commit messages -- 2.28.0
