menu "Extensions" config EXT_VTIME bool "Enable Time virtualization" default n help Enables the timer virtualization extensions. These hide the cost of running inside the VMM context. This can aid the consistency of time between multiple timers, but can cause the guest to run a good bit slower than the host in VM-intensive parts of the code. config EXT_VTSC bool "Fully virtualize guest TSC" default n depends on EXT_VTIME help Virtualize the processor time stamp counter in the guest, generally increasing consistency between various time sources but also potentially making guest time run slower than real time. config EXT_MTRRS bool "Support virtualized MTTRs" default n help Provides a virtualized set of MTTR registers config EXT_MACH_CHECK bool "Support machine-check functionality" default n help Provides a virtualized machine-check architecture config DEGUB_EXT_MACH_CHECK bool "Debug machine-check functionality" default n depends on EXT_MACH_CHECK help Enable virtual machine-check architecture debugging config EXT_INSPECTOR bool "VM Inspector" default n help Provides the inspection extension endmenu
