CONFIG_SCx200HR_TIMER: NatSemi SCx200 27MHz High-Resolution Timer Support

General informations

The Linux kernel configuration item CONFIG_SCx200HR_TIMER has multiple definitions:

NatSemi SCx200 27MHz High-Resolution Timer Support found in arch/x86/Kconfig

The configuration item CONFIG_SCx200HR_TIMER:

• prompt: NatSemi SCx200 27MHz High-Resolution Timer Support
• type: tristate
• depends on: CONFIG_SCx200
• defined in arch/x86/Kconfig
• found in Linux kernels: 2.6.24–2.6.39, 3.0–3.19, 4.0–4.20, 5.0–5.19, 6.0–6.14, 6.15-rc+HEAD
• modules built: scx200_hrt, scx200_hrt

Help text

This driver provides a clocksource built upon the on-chip 27MHz high-resolution timer. Its also a workaround for NSC Geode SC-1100's buggy TSC, which loses time when the processor goes idle (as is done by the scheduler). The other workaround is idle=poll boot option.
