CONFIG_RTC_DRV_VRTC: Virtual RTC for Intel MID platforms

General informations

The Linux kernel configuration item CONFIG_RTC_DRV_VRTC has multiple definitions:

Virtual RTC for Intel MID platforms found in drivers/rtc/Kconfig

The configuration item CONFIG_RTC_DRV_VRTC:

• prompt: Virtual RTC for Intel MID platforms
• type: tristate
• depends on: ( CONFIG_X86_INTEL_MID ) && ( CONFIG_X86_INTEL_MID )
• defined in drivers/rtc/Kconfig
• found in Linux kernels: 3.3–3.19, 4.0–4.20, 5.0–5.11
• modules built: rtc-mrst

Help text

Say "yes" here to get direct support for the real time clock found on Moorestown platforms. The VRTC is a emulated RTC that derives its clock source from a real RTC in the PMIC. The MC146818 style programming interface is mostly conserved, but any updates are done via IPC calls to the system controller FW.
