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 The commit log messages document how each driver is ready or why it is not ready. For patch 15, I could not easily find out the hardware representation of the time value, and so the SFC maintainers will have to review their low level code in order to resolve any remaining issues. Thanks, Richard * ChangeLog ** V3 - dp83640: use timespec64 throughout per Arnd's suggestion - tilegx: use timespec64 throughout per Chris' suggestion - add Jeff's acked-bys ** 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. arch/tile/gxio/mpipe.c | 4 +-- arch/tile/include/gxio/mpipe.h | 4 +-- 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 | 9 ++--- drivers/net/phy/dp83640.c | 19 +++++----- 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 +++---- 24 files changed, 160 insertions(+), 146 deletions(-) -- 1.7.10.4
