I'm announcing the release of the 6.14.2 kernel.
All users of the 6.14 kernel series must upgrade.
The updated 6.14.y git tree can be found at: git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git linux-6.14.y and can be browsed at the normal kernel.org git web browser: https://git.kernel.org/?p=linux/kernel/git/stable/linux-stable.git%3Ba=summa...
thanks,
greg k-h

Do not enable this option in production because it will negatively affect performance.
+Launch Time +=========== + +The value of the requested launch time should be based on the device's PTP +Hardware Clock (PHC) to ensure accuracy. AF_XDP takes a different data path +compared to the ETF queuing discipline, which organizes packets and delays +their transmission. Instead, AF_XDP immediately hands off the packets to +the device driver without rearranging their order or holding them prior to +transmission. Since the driver maintains FIFO behavior and does not perform +packet reordering, a packet with a launch time request will block other +packets in the same Tx Queue until it is sent. Therefore, it is recommended +to allocate separate queue for scheduling traffic that is intended for +future transmission. + +In scenarios where the launch time offload feature is disabled, the device +driver is expected to disregard the launch time request. For correct +interpretation and meaningful operation, the launch time should never be +set to a value larger than the farthest programmable time in the future +(the horizon). Different devices have different hardware limitations on the +launch time offload feature. + +stmmac driver +------------- + +For stmmac, TSO and launch time (TBS) features are mutually exclusive for +each individual Tx Queue. By default, the driver configures Tx Queue 0 to +support TSO and the rest of the Tx Queues to support TBS. The launch time +hardware offload feature can be enabled or disabled by using the tc-etf +command to call the driver's ndo_setup_tc() callback. + +The value of the launch time that is programmed in the Enhanced Normal +Transmit Descriptors is a 32-bit value, where the most significant 8 bits +represent the time in seconds and the remaining 24 bits represent the time +in 256 ns increments. The programmed launch time is compared against the +PTP time (bits[39:8]) and rolls over after 256 seconds. Therefore, the +horizon of the launch time for dwmac4 and dwxlgmac2 is 128 seconds in the +future. + +igc driver +---------- + +For igc, all four Tx Queues support the launch time feature. The launch +time hardware offload feature can be enabled or disabled by using the +tc-etf command to call the driver's ndo_setup_tc() callback. When entering +TSN mode, the igc driver will reset the device and create a default Qbv +schedule with a 1-second cycle time, with all Tx Queues open at all times. + +The value of the launch time that is programmed in the Advanced Transmit +Context Descriptor is a relative offset to the starting time of the Qbv +transmission window of the queue. The Frst flag of the descriptor can be +set to schedule the packet for the next Qbv cycle. Therefore, the horizon +of the launch time for i225 and i226 is the ending time of the next cycle +of the Qbv transmission window of the queue. For example, when the Qbv +cycle time is set to 1 second, the horizon of the launch time ranges +from 1 second to 2 seconds, depending on where the Qbv cycle is currently +running. + Querying Device Capabilities ============================
