handle_untracked_irq9
Simple and software-decoded irqs.
Usage
void handle_untracked_irq(struct
irq_desc
*
desc);
Arguments
desc
the interrupt description structure for this irq
Overview
Untracked interrupts are sent from a demultiplexing interrupt handler when the demultiplexer does not know which device it its multiplexed irq domain generated the interrupt. IRQ's handled through here are not subjected to stats tracking, randomness, or spurious interrupt detection.
Note
Like handle_simple_irq, the caller is expected to handle the ack, clear, mask and unmask issues if necessary.
