menu "Microkernel Options" source "kernel/microkernel/core/Kconfig" 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. endmenu endmenu
