** Driver Support Matrix ** Driver Support Matrix
The table below shows the Linux drivers that support the new The following two tables list the drivers that support the PHC
API. The meaning of the column abbreviations is as follows. subsystem and the Linux kernel version when they first appeared.
These drivers will create a PHC device for controlling the hardware
- SOTS: SO_TIMESTAMPING support. This comes in three flavors.
1. RAW: Supports time stamping using the PHC time values.
2. SW: Supports software time stamping using the system time.
3. SYS: Supports time stamping using PHC time values scaled to
the system time. This is a legacy mode and its use in new
drivers is discouraged.
- PHC: PTP Hardware Clock support. These drivers will offer a
character device that allows direct control of the hardware
clock. clock.
- PHY: Supports time stamping in the PHY. This indicates an *** Hardware Timestamping - PHY
Ethernet MAC driver supporting SO_TIMESTAMPING and PHC in the
PHY. If you have or build a computer that combines this MAC with
a PTP capable PHY, then it will work with the Linux PHC
subsystem.
- VER: Linux kernel version when the PTP API support was added. |---------+-------------------------------+---------|
