The IEEE 1588 standard defines a method to precisely
|
||
|
|
synchronize distributed clocks over Ethernet networks. The
|
||
|
|
standard defines a Precision Time Protocol (PTP), which can
|
||
|
|
be used to achieve synchronization within a few dozen
|
||
|
|
microseconds. In addition, with the help of special hardware
|
||
|
|
time stamping units, it can be possible to achieve
|
||
|
|
synchronization to within a few hundred nanoseconds.
|
||
|

This driver adds support for PTP clocks as character
|
||
|
|
devices. If you want to use a PTP clock, then you should
|
||
|
|
also enable at least one clock driver as well.
|
||
|
|
|
||
|
|
To compile this driver as a module, choose M here: the module
|
||
|
|
will be called ptp.
