Function Documentation

configureMallocBehavior()

bool mcx::utils::configureMallocBehavior

(

size_t

size_mb

)

Configures memory behavior for Real-time.

Locks all current and future pages from preventing of being paged. Touches each page in this piece of memory to get it mapped into RAM.

Parameters

size_mb

- size of RAM to reserve in Megabytes.

Returns

true on success.

running()

bool mcx::utils::running

(

)

Indicates that process is running.

Returns

true if no system terminate signals have been received.

startRealTime() [1/3]

bool mcx::utils::startRealTime

(

)

Activates Real-time mode and isolates CPUs.

Returns

true on success

startRealTime() [2/3]

bool mcx::utils::startRealTime

(

cmd_line::Realtime

opt

)

Activates Real-time mode and isolates CPUs.

@opt - struct with realtime options.

Returns

true on success

startRealTime() [3/3]

bool mcx::utils::startRealTime	(	const std::vector< uint32_t > &	cpu_list,
		size_t	size_mb = 256
	)

Activates Real-time mode and isolates CPUs.

@cpu_list - list of the CPUs to isolate.

Parameters

size_mb

- size of RAM to reserve in Megabytes.

Returns

true on success

stopRealTime()

void mcx::utils::stopRealTime

(

cmd_line::Realtime

opt

)

Deactivate Real-time mode, removes CPUs' isolation.

@opt - struct with realtime options.
