-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
Provides a virtualized set of MTTR registers
config EXT_MACH_CHECK
- bool "Support Machine Check functionality"
+ bool "Support machine-check functionality"
default n
help
- Provides a virtualized machine check architecture
+ Provides a virtualized machine-check architecture
+config DEBUG_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"
help
Provides the inspection extension
-config SW_INTERRUPTS
- bool "Enable interception and hooking of software interrupts"
- default n
- help
- This feature will cause the VMM to intercept the execution
- of software interrupts (i.e. the INTn instruction) and enable
- any INT vector to be hooked
+config EXT_VMWARE
+ bool "VMWare Persona"
+ default n
+ help
+ Provides a VMWare persona to allow TSC calibration
-config SWINTR_PASSTHROUGH
- bool "Hook all unhandled sofware interrupts for passthrough"
- depends on SW_INTERRUPTS
- default n
- help
- If enabled, this will cause all software interrupts
- (INT instruction vectors) to be hooked for passthrough.
- May reduce performance but useful for debugging.
+config EXT_SCHED_EDF
+ bool "EDF Real-time Scheduler"
+ default n
+ help
+ Provides a full real-time EDF scheduler for VM cores
-config SYSCALL_HIJACK
- bool "Enable System Call Hijacking"
- depends on SW_INTERRUPTS
- default n
- help
- Enable the VMM to hijack system calls executed by the guest.
- If enabled, the VMM will hook execution of INT 80
- (support for Fast-System Calls coming soon)
+config DEBUG_EXT_SCHED_EDF
+ bool "Debugging for EDF Real-time Scheduler"
+ default n
+ depends on DEBUG_ON && EXT_SCHED_EDF
-config SYSCALL_PASSTHROUGH
- bool "Hook all unhandled system calls for passthrough"
- depends on SYSCALL_HIJACK
- default n
- help
- If enabled, this option will cause all system calls
- that are not explicitly hooked to be hooked for
- passthrough. This is useful for debugging.
+config EXT_CPU_MAPPER_EDF
+ bool "CPU Mapper for EDF Scheduler"
+ default n
+ help
+ Provides an CPU Mapper for EDF scheduler
+
+config DEBUG_EXT_CPU_MAPPER_EDF
+ bool "Debugging for EDF CPU Mapper"
+ default n
+ depends on DEBUG_ON && EXT_CPU_MAPPER_EDF
+
+config TM_FUNC
+ bool "Enable Intel Transactional Memory Emulation"
+ default n
+ depends on SVM && QUIX86 && EXPERIMENTAL
+ help
+ Enable Palacios to emulate Intel's hardware
+ transactional memory extensions. This is the
+ Restricted Transactional Memory (RTM) featureset,
+ part of Intel's TSX extensions.
+
+ Ironically, this feature is only implemented for AMD (SVM)
-config HIJACK_SYSCALL_MSR
- bool "Intercept Syscall-related MSR reads & writes"
- depends on SYSCALL_HIJACK
+config DEBUG_TM_FUNC
+ bool "Enable transactional memory emulation debugging output"
+ depends on DEBUG_ON && TM_FUNC
default n
help
- Allow the VMM to intercept reads and writes to MSRs
- related to SYSCALL and SYSENTER instructions. Specifically,
- it will intercept R/W to STAR, CSTAR, and LSTAR.
+ Enable Transactional Memory debugging output
