config KERNEL_DIR
	string
	default ukernel
	depends on MICROKERNEL
	help
		This option holds the name of the directory used
		by sysgen to locate the config1p.vpf file.

config	WORKLOAD_MONITOR
	bool
	prompt "Workload monitoring [EXPERIMENTAL]"
	default y
	depends on MICROKERNEL && EXPERIMENTAL
	help
	This option instructs the kernel to record the percentage of time
	the system is doing useful work (i.e. is not idle).

# NOTE:
# All the API_* config options are being introduced to have the capability
# to enable or disable all different microkernel APIs and to remove them
# from the conpilation set in the future.
# Right now, they are hidden options because the source code does not
# necessarily support the capability to be eliminated from the compilation
# set, since there are some dependencies that might need to be solved.

config API_MEMMAP
	bool
	default y
	depends on MICROKERNEL
	help
	This option adds the memory map API
	to the microkernel image.

config API_MEMPOOL
	bool
	default y
	depends on MICROKERNEL
	help
	This option add the memory pool API
	to the microkernel image.

config API_TASKIRQ
	bool
	default y
	depends on MICROKERNEL
	help
	This option add the task irq API
	to the microkernel image.

config	MAX_NUM_TASK_IRQS
	int
	prompt "Number of task IRQ objects"
	default 0
	depends on MICROKERNEL && API_TASKIRQ
	help
	This option specifies the maximum number of IRQs that may be
	utilized by task level device drivers. A value of zero disables
	this feature.

config API_DONOTHING
	bool
	default y
	depends on MICROKERNEL
	help
	This option add the idle API
	to the microkernel image.

config API_OFFLD2FIBER
	bool
	default y
	depends on MICROKERNEL
	help
	This option add the offload to fiber API
	to the microkernel image.

config API_EVENTS
	bool
	default y
	depends on MICROKERNEL
	help
	This option add the event mangement API
	to the microkernel image.

config API_MAILBOX
	bool
	default y
	depends on MICROKERNEL
	help
	This option add the mailbox API
	to the microkernel image.

config API_MUTEX
	bool
	default y
	depends on MICROKERNEL
	help
	This option add the mutex API
	to the microkernel image.

config API_FIFO
	bool
	default y
	depends on MICROKERNEL
	help
	This option add the FIFO API
	to the microkernel image.

config API_SEMAPHORES
	bool
	default y
	depends on MICROKERNEL
	help
	This option add the semaphores API
	to the microkernel image.

config API_TIMER
	bool
	default y
	depends on MICROKERNEL
	help
	This option add the timer API
	to the microkernel image.

source "kernel/microkernel/timer/Kconfig"

config API_CHANNEL
	bool
	default y
	depends on MICROKERNEL
	help
	This option add the channel API
	to the microkernel image.

config  TASK_MONITOR
	bool
	prompt "Task monitoring [EXPERIMENTAL]"
	default n
	depends on MICROKERNEL
	help
	This option instructs the kernel to record significant task
	activities. These can include: task switches, task state changes,
	kernel service requests, and the signalling of events.

config  TASK_MONITOR_CAPACITY
	int
	prompt "Trace buffer capacity (# of entries)"
	default 300
	depends on TASK_MONITOR
	help
	This option specifies the number of entries in the task monitor's
	trace buffer. Each entry requires 12 bytes.

config  TASK_MONITOR_MASK
	int
	prompt "Trace buffer mask"
	default 15
	depends on TASK_MONITOR
	help
	This option specifies which task execution activities are captured
	in the task monitor's trace buffer. The following values can be
	OR-ed together to form the mask:
		1 (MON_TSWAP): task switch
		2 (MON_STATE): task state change
		4 (MON_KSERV): task execution of kernel APIs
		8 (MON_EVENT): task event signalled

config ADVANCED_POWER_MANAGEMENT
	bool
	prompt "Advanced power management"
	default n
	depends on MICROKERNEL
	help
	This option enables the BSP to implement extra power management
	policies whenever the kernel becomes idle. The kernel informs the
	BSP of the number of ticks until the next kernel timer expires by
	calling the BSP function _SysPowerSaveIdle().

menu "Advanced Power Management Features"
	depends on MICROKERNEL && ADVANCED_POWER_MANAGEMENT && ADVANCED_IDLE_SUPPORTED

config  ADVANCED_IDLE
	bool
	prompt "Advanced idle state"
	default n
	depends on ADVANCED_POWER_MANAGEMENT && ADVANCED_IDLE_SUPPORTED
	help
	This option enables the kernel to interface to a custom advanced idle
	power saving manager. This permits the system to enter a custom
	power saving state when the kernel becomes idle for extended periods,
	and then to restore the system to its previous state (rather than
	booting up from scratch) when the kernel is re-activated.

config ADV_IDLE_STACK_SIZE
	int
	prompt "Advanced idle state stack size"
	default 16
	depends on ADVANCED_IDLE
	help
	This option defines the size of the separate stack used during the
	system state check while the booting up. A separate stack is used
	to avoid memory corruption on the system re-activation from power
	down mode. The stack size must be large enough to hold the return
	address (4 bytes) and the _AdvIdleCheckSleep() stack frame.
