ARM GIC functions

[Expand]

function ARMGICCreate(DistAddress,CPUAddress:PtrUInt):PGICDevice;

Description: To be documented

Note	None documented

[Expand]

function ARMGICStart(GIC:PGICDevice):LongWord;

Description: To be documented

Note	None documented

[Expand]

function ARMGICGetEntry(GIC:PGICDevice; CPUID,Number,Flags:LongWord; var Entry:TInterruptEntry; Index:LongWord):LongWord;

Description: To be documented

Note	The returned Entry is a copy of the registered value. Caller should free Entry if required. For shared entries the Index parameter indicates which entry in the chain to return (0 equals first etc).

[Expand]

function ARMGICRegisterEntry(GIC:PGICDevice; const Entry:TInterruptEntry):LongWord;

Description: To be documented

Note	Entry must be allocated from heap as a pointer so it will be retained while the interrupt remains registered. Entry must not be freed by the caller.

[Expand]

function ARMGICDeregisterEntry(GIC:PGICDevice; const Entry:TInterruptEntry):LongWord;

Description: To be documented

Note	The Entry can be a local temporary copy allocated either from the stack or on the heap, this routine will free the original Entry passed to Register once it is successfully deregistered. Caller should free Entry if required.

ARM GIC interrupt functions

[Expand]

function ARMGICDispatchIRQ(CPUID:LongWord; Thread:TThreadHandle):TThreadHandle;

Description: To be documented

Note	Called by ARMv7/8IRQHandler in PlatformARMv7/8

[Expand]

function ARMGICDispatchFIQ(CPUID:LongWord; Thread:TThreadHandle):TThreadHandle;

Description: To be documented

Note	Called by ARMv7/8FIQHandler in PlatformARMv7/8

[Expand]

function ARMGICDispatchInterrupt(CPUID:LongWord; Thread:TThreadHandle):TThreadHandle;

Description: Process any pending IRQ/FIQ requests

Note	Called by ARMGICDispatchIRQ/ARMGICDispatchFIQ. A DataMemoryBarrier is executed before and after calling this function.
