  • 8dbbf8542   selftests: move ptp tests from Documentation/ptp ... Browse Code »

    Remove ptp from Makefile to move the test to selftests. Update ptp Makefile
    to work under selftests. ptp will not be run as part of selftests suite and
    will not be included in install targets. They can be built separately for
    now.

  • 719f1aa4a   ptp: Add PTP_SYS_OFFSET_PRECISE for driver crosstimestamping ... Browse Code »

    Currently, network /system cross-timestamping is performed in the
    PTP_SYS_OFFSET ioctl. The PTP clock driver reads gettimeofday() and
    the gettime64() callback provided by the driver. The cross-timestamp
    is best effort where the latency between the capture of system time
    (getnstimeofday()) and the device time (driver callback) may be
    significant.

    The getcrosststamp() callback and corresponding PTP_SYS_OFFSET_PRECISE
    ioctl allows the driver to perform this device/system correlation when
    for example cross timestamp hardware is available. Modern Intel
    systems can do this for onboard Ethernet controllers using the ART
    counter. There is virtually zero latency between captures of the ART
    and network device clock.

    The capabilities ioctl (PTP_CLOCK_GETCAPS), is augmented allowing
    applications to query whether or not drivers implement the
    getcrosststamp callback, providing more precise cross timestamping.

    Signed int - unsigned int comparison fixed in mpssd, prctl, ptp, and
    timers in Documentation. In places where 'int argc' and 'const char
    **argv' are not used, they are replaced with void

  • 9ae6d4935   testptp: Silence compiler warnings on ppc64 ... Browse Code »

    When compiling Documentation/ptp/testptp.c the following compiler
    warnings are printed out:

    Documentation/ptp/testptp.c: In function ‘main’:
    Documentation/ptp/testptp.c:367:11: warning: format ‘%lld’ expects argument
    of type ‘long long int’, but argument 3 has type ‘__s64’ [-Wformat=]
    event.t.sec, event.t.nsec);
    ^
    Documentation/ptp/testptp.c:505:5: warning: format ‘%lld’ expects argument
    of type ‘long long int’, but argument 2 has type ‘__s64’ [-Wformat=]
    (pct+2*i)->sec, (pct+2*i)->nsec);
    ^
    Documentation/ptp/testptp.c:507:5: warning: format ‘%lld’ expects argument
    of type ‘long long int’, but argument 2 has type ‘__s64’ [-Wformat=]
    (pct+2*i+1)->sec, (pct+2*i+1)->nsec);
    ^
    Documentation/ptp/testptp.c:509:5: warning: format ‘%lld’ expects argument
    of type ‘long long int’, but argument 2 has type ‘__s64’ [-Wformat=]
    (pct+2*i+2)->sec, (pct+2*i+2)->nsec);

    This happens because __s64 is by default defined as "long" on ppc64,
    not as "long long". However, to fix these warnings, it's possible to
    define the __SANE_USERSPACE_TYPES__ so that __s64 gets defined to
    "long long" on ppc64, too.

  • 5345c1d41   ptp: restore the makefile for building the test program. ... Browse Code »

    This patch brings back the makefile called testptp.mk which was removed
    in commit adb19fb66eee (Documentation: add makefiles for more targets).

    While the idea of that commit was to improve build coverage of the
    examples, the new Makefile is unable to cross compile the testptp program.
    In contrast, the deleted makefile was able to do this just fine.

    This patch fixes the regression by restoring the original makefile.

  • d94ba80eb   ptp: Added a brand new class driver for ptp clocks. ... Browse Code »

    This patch adds an infrastructure for hardware clocks that implement
    IEEE 1588, the Precision Time Protocol (PTP). A class driver offers a
    registration method to particular hardware clock drivers. Each clock is
    presented as a standard POSIX clock.

    The ancillary clock features are exposed in two different ways, via
    the sysfs and by a character device.
