[Linuxptp-devel] [PATCH V2 5/8] config: Add a configuration option for TC mode.

This patch adds a new configuation option that enables transparent clock mode. When TC mode is specified, the configured delay mechanism must also match. The legacy behavior of upgrading a multi-port clock from OC to BC is preserved. Signed-off-by: Richard Cochran ---

[Linuxptp-devel] [PATCH V2 6/8] config: Add a configuration option for preventing loops in TC mode.

According to 1588, PTP message loops are simply someone else's problem with respect to transparent clocks. Since we are running the BMCA for syntonization anyway, we might as well go ahead and implement the spanning tree for PTP messages. Signed-off-by: Richard Cochran

[Linuxptp-devel] [PATCH V2 3/8] p2p_tc: Implement a peer to peer transparent clock.

The P2P TC forwards Announce, Management, Signaling, and Sync messages, consumes P2P Delay messages, and drops E2E Delay messages. This implementation tracks the GM using the BMCA in order to syntonize (or possibly even synchronize) with it. Signed-off-by: Richard Cochran

[Linuxptp-devel] [PATCH V2 0/8] Transparent Clock - third and final part

This series add support for running a TC over multiple ports. This applies on top of my recently posted telecom series. Comments, testing, and review are most welcome. Changed in V2: ~~ - Detect and drop frames that arrive with time stamps. - Add an option to enforce a spanning

[Linuxptp-devel] [PATCH V2 2/8] tc: Add the transparent clock implementation.

This patch adds code that sends an event messages received on one port out all the other ports and calculates the residence time. The correction, ingress port, and the original message are remembered in a TC transmit descriptor. These descriptors are recycled in a memory pool in a similar way to

[Linuxptp-devel] [PATCH V2 6/6] telecom: Introduce the G.8275.masterOnly option.

When G.8275.masterOnly is true, the port always returns NULL when computing its best foreign master. As a result, the port will never enter the SLAVE state, and the clock will ignore Announce messages received on that port. This attribute is specifically called out in G.8275.1 and G.8275.2, and

[Linuxptp-devel] [PATCH V2 1/6] telecom: Introduce the local priority attribute into the data set.

The Telecom Profiles G.8275.1 and G.8275.2 have invented a new per-port and per-clock attribute, not in 1588, called "localPriority". The use of this attribute is a distinguishing feature of the telecom data set comparison algorithm. This patch adds the attribute, hard coded to its default value.
