CONFIG_CAVIUM_PTP: Cavium PTP coprocessor as PTP clock

General informations

The Linux kernel configuration item CONFIG_CAVIUM_PTP:

• prompt: Cavium PTP coprocessor as PTP clock
• type: tristate
• depends on: ( CONFIG_64BIT && CONFIG_PCI ) && ( CONFIG_PTP_1588_CLOCK )
• defined in drivers/net/ethernet/cavium/Kconfig
• found in Linux kernels: 4.16–4.20, 5.0–5.19, 6.0–6.12
• modules built: cavium_ptp

Help text

This driver adds support for the Precision Time Protocol Clocks and Timestamping coprocessor (PTP) found on Cavium processors. PTP provides timestamping mechanism that is suitable for use in IEEE 1588 Precision Time Protocol or other purposes. Timestamps can be used in BGX, TNS, GTI, and NIC blocks.
