__STATIC_FORCEINLINE void PLIC_SetPriority (uint32_t source, uint32_t priority)

Set interrupt priority for selected source plic.

This function set interrupt priority for selected source plic.

Remark

See also

PLIC_GetPriority

Parameters:

source – [in] interrupt source
priority – [in] interrupt priority

__STATIC_FORCEINLINE uint32_t PLIC_GetPriority (uint32_t source)

Get interrupt priority for selected source plic.

priority – [in] interrupt priority

__STATIC_FORCEINLINE uint32_t PLIC_ClaimContextInterrupt (uint32_t ctxid)

Claim interrupt for plic for selected context.

This function claim interrupt for plic for selected context.

Remark

A successful claim will also atomically clear the corresponding pending bit on the interrupt source. The PLIC can perform a claim at any time and the claim operation is not affected by the setting of the priority threshold register.

See also

PLIC_CompleteContextInterrupt

Parameters:: ctxid – [in] selected context id
Returns:: the ID of the highest priority pending interrupt or zero if there is no pending interrupt

__STATIC_FORCEINLINE void PLIC_CompleteContextInterrupt (uint32_t ctxid, uint32_t source)

Complete interrupt for plic for selected context.

This function complete interrupt for plic for selected context.

Remark

The PLIC signals it has completed executing an interrupt handler by writing the interrupt ID it received from the claim to the claim/complete register. The PLIC does not check whether the completion ID is the same as the last claim ID for that context. If the completion ID does not match an interrupt source that is currently enabled for the context, the completion is silently ignored.

See also

PLIC_ClaimContextInterrupt

Parameters:: ctxid – [in] selected context id
Returns:: the ID of the highest priority pending interrupt or zero if there is no pending interrupt
