Subject: [PATCH V9 00/13] ptp: IEEE 1588 hardware clock support
Newsgroups: gmane.linux.kernel
Date: Thursday 13th January 2011 11:31:06 UTC (over 5 years ago)
* Introduction

  The aim of this patch set is to add support for PTP Hardware Clocks
  (PHCs) into the Linux kernel.

  The first nine patches provide infrastructure supporting dynamic
  POSIX clock devices. This new code will be useful for other kinds of
  new clocks, not just PHCs.

  The last four patches implement the PHC code.

  Support for obtaining timestamps from a PHC already exists via the
  SO_TIMESTAMPING socket option, integrated in kernel version 2.6.30.
  This patch set completes the picture by allow user space programs to
  adjust the PHC and to control its ancillary features.

* Patch ChangeLog

** v9
*** dynamic posix clocks
    - changed the kernel interface to be less idiosyncratic
*** ptp hardware clocks
    - changed the kernel interface to be less idiosyncratic
*** posix clock/ntp syscalls
    - completely removed the CLOCK_DISPATCH macro
    - pick a bit for ADJ_SETOFFSET that is unused by BSD
*** ixp driver
    - resolved todo regarding npe to channel mapping
    - removed weird CamelCase from register definitions
    - removed wrapper functions for reading/writing registers

* Previous Discussions

  This patch set previously appeared on the netdev list. Since V5 of
  the character device patch set, the discussion has moved to the
  lkml.
