- rtnl: Fix rtnl_rtattr_parse() to process max attribute.
|
| |
-
|
| |
- Initialize the whole array passed to rtnl_rtattr_parse() and don't
|
| |
- ignore the last attribute with the maximum value. This will be needed to
|
| |
- get the ETHTOOL_A_PHC_VCLOCKS_INDEX attribute.

|
| |
- Add support for binding sockets to virtual clocks.
|
| |
-
|
| |
- With the latest kernels it is possible to create virtual PHCs on top of
|
| |
- a free-running physical PHC. In order for the application to get
|
| |
- timestamps captured by the clock which it is controlling, it needs to
|
| |
- bind its sockets to the clock using a new field in the SO_TIMESTAMPING
|
| |
- option.
|
| |
-
|
| |
- Extend the interface structure with the vclock index and modify the
|
| |
- transport code to pass it to sk_timestamping_init() to bind the sockets
|
| |
- to the clock.

- When running in the automatic mode, get the PHC index of the port

- phc2sys -a to synchronize (to) a virtual clock.

- timemaster: Add support for virtual clocks.
|
| |
-
|
| |
- Add "use_vclocks" option to enable synchronization with virtual clocks.
|
| |
- This enables multiple ptp4l instances sharing an interface to use
|
| |
- hardware timestamping. By default, vclocks are enabled if running on
|
| |
- Linux 5.18 or later, which should have all features to make them work as
|
| |
- well as physical clocks.
|
| |
-
|
| |
- When preparing the script, count how many vclocks are needed for each
|
| |
- physical clock. Add a placeholder option in the form of "--phc_index
|
| |
- %PHC0-0%" to the generated ptp4l commands that need hardware clock. The
|
| |
- index of the virtual clock is unknown at this point.
|
| |
-
|
| |
- When running the script (not just printing), create the required number
|
| |
- of virtual clocks by writing to /sys/.../n_vclocks and fix the
|
| |
- --phc_index options to refer to the indices of the created vclocks. On
|
| |
- exit, remove the virtual clocks to restore the original state.

This updates linuxptp to a more recent snapshots, drops included patches, and adds a few more that FB is in the process of upstreaming. Also temporarily disable three tests (16-largewander 19-externalstep 31-leapsecond) while we figure out why they're failing.
