CONFIG_PTP_1588_CLOCK_PCH: Intel PCH EG20T as PTP clock

General informations

The Linux kernel configuration item CONFIG_PTP_1588_CLOCK_PCH:

• prompt: Intel PCH EG20T as PTP clock
• type: tristate
• depends on: ( CONFIG_MIPS_GENERIC || CONFIG_X86_32 || CONFIG_COMPILE_TEST ) && ( CONFIG_HAS_IOMEM && CONFIG_PCI ) && ( CONFIG_NET ) && ( CONFIG_PTP_1588_CLOCK )
• defined in drivers/ptp/Kconfig
• found in Linux kernels: 3.4–3.19, 4.0–4.20, 5.0–5.19, 6.0–6.8, 6.9-rc+HEAD
• modules built: ptp_pch

Help text

This driver adds support for using the PCH EG20T as a PTP clock. The hardware supports time stamping of PTP packets when using the end-to-end delay (E2E) mechanism. The peer delay mechanism (P2P) is not supported.

This clock is only useful if your PTP programs are getting hardware time stamps on the PTP Ethernet packets using the SO_TIMESTAMPING API.

To compile this driver as a module, choose M here: the module will be called ptp_pch.
