Message-Id: <1366733211-10228-1-git-send-email-amirv@mellanox.com> Date: Tue, 23 Apr 2013 19:06:46 +0300 From: Amir Vadai <amirv@...lanox.com> To: "David S. Miller" <davem@...emloft.net> Cc: netdev@...r.kernel.org, Richard Cochran <richardcochran@...il.com>, Or Gerlitz <ogerlitz@...lanox.com>, Eugenia Emantayev <eugenia@...lanox.com>, Amir Vadai <amirv@...lanox.com> Subject: [PATCH net-next V3 0/5] net/mlx4: HW timestamping support This V3 series of patches introduces Ethernet HW timestamping support in the mlx4 driver. The series is made of of five patches 1. Add timestamping device capability 2. Read HCA frequency and map internal clock 3. Add HW timestamping (TS) support -- Enable/disable HW timestamping for incoming and/or outgoing packets. Add and initialize all structs and callbacks needed by the kernel timestamping API. 4. Add needed call to enable software timestamping 5. Add a service task to mlx4_en to run periodic tasks. Currently only running a watchdog to prevent clock overflow The patches provide raw HW timestamps, where registeration in the driver as PHC class device will be done in a 2nd step, once the basic code is merged. Changes from V0: - accept HWTSTAMP_FILTER_PTP_ and HWTSTAMP_FILTER_SOME flags but reply with HWTSTAMP_FILTER_ALL - remove usage of the timecompare API - call netdev_features_change() after changing dev->features Changes from V1: - get_ts_info function provided. - watchdog function was added to catch overflows - indentation and style fixes - en_timestamp.c => en_clock.c - use utility clockcounter utility functions Changes from V2: - mac => MAC - no need for macro CORE_CLOCK_MASK - changed clocksource shift to 14 to prevent overflows - added some comments to make calculations clearer - use NSEC_PER_SEC macro - initialize overflow_period in jiffies and not seconds Amir Vadai (3): net/mlx4_en: Add HW timestamping (TS) support net/mlx4_en: Support software timestamping net/mlx4_en: Add a service task Eugenia Emantayev (2): net/mlx4_core: Add timestamping device capability net/mlx4_core: Read HCA frequency and map internal clock drivers/infiniband/hw/mlx4/cq.c | 2 +- drivers/net/ethernet/mellanox/mlx4/Makefile | 2 +- drivers/net/ethernet/mellanox/mlx4/cq.c | 10 +- drivers/net/ethernet/mellanox/mlx4/en_clock.c | 151 +++++++++++++++++++++ drivers/net/ethernet/mellanox/mlx4/en_cq.c | 10 +- drivers/net/ethernet/mellanox/mlx4/en_ethtool.c | 30 ++++ drivers/net/ethernet/mellanox/mlx4/en_main.c | 5 + drivers/net/ethernet/mellanox/mlx4/en_netdev.c | 99 ++++++++++++++ drivers/net/ethernet/mellanox/mlx4/en_resources.c | 3 + drivers/net/ethernet/mellanox/mlx4/en_rx.c | 29 ++++- drivers/net/ethernet/mellanox/mlx4/en_tx.c | 31 ++++- drivers/net/ethernet/mellanox/mlx4/fw.c | 18 +++- drivers/net/ethernet/mellanox/mlx4/fw.h | 1 + drivers/net/ethernet/mellanox/mlx4/main.c | 79 +++++++++++ drivers/net/ethernet/mellanox/mlx4/mlx4.h | 6 +- drivers/net/ethernet/mellanox/mlx4/mlx4_en.h | 25 ++++- include/linux/mlx4/cq.h | 16 +++ include/linux/mlx4/device.h | 10 +- 18 files changed, 507 insertions(+), 20 deletions(-) create mode 100644 drivers/net/ethernet/mellanox/mlx4/en_clock.c -- 1.7.8.2 -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
