Function Documentation

AcquireMpSpinLock()

VOID AcquireMpSpinLock

(

IN OUT SPIN_LOCK *

MpSpinLock

)

Acquire a spin lock when Multi-processor supported.

It will block in the function if cannot get the access control. If Multi-processor is not supported, return directly.

Parameters

[in,out]

MpSpinLock

A pointer to the spin lock.

Definition at line 25 of file DebugMp.c.

DebugAgentIsBsp()

BOOLEAN DebugAgentIsBsp

(

IN UINT32

ProcessorIndex

)

Check if the specified processor is BSP or not.

Parameters

[in]

ProcessorIndex

Processor index value.

Return values

TRUE	It is BSP.
FALSE	It isn't BSP.

Definition at line 134 of file DebugMp.c.

FindNextPendingBreakCpu()

UINT32 FindNextPendingBreakCpu

(

VOID

)

Check the next pending breaking CPU.

Return values

others	There is at least one processor broken, the minimum index number of Processor returned.
-1	No any processor broken.

Definition at line 311 of file DebugMp.c.

GetProcessorIndex()

UINT32 GetProcessorIndex

(

VOID

)

Get the current processor's index.

Returns

Processor index value.

Definition at line 97 of file DebugMp.c.

HaltOtherProcessors()

VOID HaltOtherProcessors

(

IN UINT32

CurrentProcessorIndex

)

Break the other processor by send IPI.

Parameters

[in]

CurrentProcessorIndex

Current processor index value.

Definition at line 68 of file DebugMp.c.

IsAllCpuRunning()

BOOLEAN IsAllCpuRunning

(

VOID

)

Check if all processors are in running status.

Return values

TRUE	All processors run.
FALSE	At least one processor does not run.

Definition at line 334 of file DebugMp.c.

IsCpuStopped()

BOOLEAN IsCpuStopped

(

IN UINT32

ProcessorIndex

)

Check if processor is stopped already.

Parameters

[in]

ProcessorIndex

Processor index value.

Return values

TRUE	Processor is stopped already.
TRUE	Processor isn't stopped.

Definition at line 237 of file DebugMp.c.

IsFirstBreakProcessor()

BOOLEAN IsFirstBreakProcessor

(

IN UINT32

ProcessorIndex

)

Check if the current processor is the first breaking processor.

If yes, halt other processors.

Parameters

[in]

ProcessorIndex

Processor index value.

Returns

TRUE This processor is the first breaking processor.

FALSE This processor is not the first breaking processor.

Definition at line 361 of file DebugMp.c.

ReleaseMpSpinLock()

VOID ReleaseMpSpinLock

(

IN OUT SPIN_LOCK *

MpSpinLock

)

Release a spin lock when Multi-processor supported.

Parameters

[in,out]

MpSpinLock

A pointer to the spin lock.

Definition at line 50 of file DebugMp.c.

SetCpuBreakFlagByIndex()

VOID SetCpuBreakFlagByIndex	(	IN UINT32	ProcessorIndex,
		IN BOOLEAN	BreakFlag
	)

Set processor break flag bitmask in MP context.

Parameters

[in]	ProcessorIndex	Processor index value.
[in]	BreakFlag	TRUE means set break flag. FALSE means clean break flag.

Definition at line 204 of file DebugMp.c.

SetCpuRunningFlag()

VOID SetCpuRunningFlag

(

IN BOOLEAN

RunningFlag

)

Set the run command flag.

Parameters

[in]

RunningFlag

TRUE means run command flag is set. FALSE means run command flag is cleared.

Definition at line 260 of file DebugMp.c.

SetCpuStopFlagByIndex()

VOID SetCpuStopFlagByIndex	(	IN UINT32	ProcessorIndex,
		IN BOOLEAN	StopFlag
	)

Set processor stop flag bitmask in MP context.

Parameters

[in]	ProcessorIndex	Processor index value.
[in]	StopFlag	TRUE means set stop flag. FALSE means clean break flag.

Definition at line 172 of file DebugMp.c.

SetDebugViewPoint()

VOID SetDebugViewPoint

(

IN UINT32

ProcessorIndex
