function ARMGICCreate(DistAddress,CPUAddress:PtrUInt):PGICDevice;
Description: To be documented
| Note | None documented |
|---|
function ARMGICStart(GIC:PGICDevice):LongWord;
Description: To be documented

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). |
|---|
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. |
|---|
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. |
