CONFIG_VCPU_STALL_DETECTOR: Guest vCPU stall detector

General informations

The Linux kernel configuration item CONFIG_VCPU_STALL_DETECTOR:

• prompt: Guest vCPU stall detector
• type: tristate
• depends on: CONFIG_OF && CONFIG_HAS_IOMEM
• defined in drivers/misc/Kconfig
• found in Linux kernels: 6.0–6.12, 6.13-rc+HEAD
• modules built: vcpu_stall_detector

Help text

When this driver is bound inside a KVM guest, it will periodically "pet" an MMIO stall detector device from each vCPU and allow the host to detect vCPU stalls.

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

If you do not intend to run this kernel as a guest, say N.
