In addition, I reviewed how each driver and device represents the time value at the hardware register level. Most of the drivers are ready, but a few will need some work before the year 2038, as shown: Patch Driver ------------------------------------------------ 12 drivers/net/ethernet/intel/igb/igb_ptp.c 15 ? drivers/net/ethernet/sfc/ptp.c 16 drivers/net/ethernet/stmicro/stmmac/stmmac_ptp.c 18 ? drivers/net/ethernet/tile/tilegx.c 19 drivers/net/phy/dp83640.c The commit log message documents how each driver is ready or why it is not ready. For patches 15 and 18, I could not easily find out the hardware representation of the time value, so I would ask the maintainers for a review. Thanks, Richard * ChangeLog ** V2 - use the new methods in the posix clock code right away (patch #3) Richard Cochran (23): ptp: introduce get/set time methods with explicit 64 bit seconds. ptp: use the 64 bit gettime method for the SYS_OFFSET ioctl. ptp: use the 64 bit get/set time methods for the posix clock. ptp: blackfin: convert to the 64 bit get/set time methods. ptp: xgbe: convert to the 64 bit get/set time methods. ptp: bnx2x: convert to the 64 bit get/set time methods. ptp: tg3: convert to the 64 bit get/set time methods. ptp: fec: convert to the 64 bit get/set time methods. ptp: gianfar: convert to the 64 bit get/set time methods. ptp: e1000e: convert to the 64 bit get/set time methods. ptp: fm10k: convert to the 64 bit get/set time methods. ptp: i40e: convert to the 64 bit get/set time methods. ptp: igb: convert to the 64 bit get/set time methods. ptp: ixgbe: convert to the 64 bit get/set time methods. ptp: mlx4: convert to the 64 bit get/set time methods. ptp: sfc: convert to the 64 bit get/set time methods. ptp: stmmac: convert to the 64 bit get/set time methods. ptp: cpts: convert to the 64 bit get/set time methods. ptp: tilegx: convert to the 64 bit get/set time methods. ptp: dp83640: convert to the 64 bit get/set time methods. ptp: ixp46x: convert to the 64 bit get/set time methods. ptp: pch: convert to the 64 bit get/set time methods. ptp: remove 32 bit get/set methods. drivers/net/ethernet/adi/bfin_mac.c | 8 ++--- drivers/net/ethernet/amd/xgbe/xgbe-ptp.c | 13 +++---- drivers/net/ethernet/broadcom/bnx2x/bnx2x_main.c | 8 ++--- drivers/net/ethernet/broadcom/tg3.c | 10 +++--- drivers/net/ethernet/freescale/fec_ptp.c | 8 ++--- drivers/net/ethernet/freescale/gianfar_ptp.c | 13 +++---- drivers/net/ethernet/intel/e1000e/ptp.c | 16 ++++----- drivers/net/ethernet/intel/fm10k/fm10k_ptp.c | 12 +++---- drivers/net/ethernet/intel/i40e/i40e_ptp.c | 26 +++++++------- drivers/net/ethernet/intel/igb/igb_ptp.c | 41 +++++++++++----------- drivers/net/ethernet/intel/ixgbe/ixgbe_ptp.c | 14 ++++---- drivers/net/ethernet/mellanox/mlx4/en_clock.c | 11 +++--- drivers/net/ethernet/sfc/ptp.c | 22 ++++++------ drivers/net/ethernet/stmicro/stmmac/stmmac_ptp.c | 8 ++--- drivers/net/ethernet/ti/cpts.c | 12 +++---- drivers/net/ethernet/tile/tilegx.c | 16 +++++---- drivers/net/phy/dp83640.c | 12 ++++--- drivers/ptp/ptp_chardev.c | 8 ++--- drivers/ptp/ptp_clock.c | 12 +++++-- drivers/ptp/ptp_ixp46x.c | 8 ++--- drivers/ptp/ptp_pch.c | 8 ++--- include/linux/ptp_clock_kernel.h | 12 +++---- 22 files changed, 158 insertions(+), 140 deletions(-) -- 1.7.10.4
