Name
handle_untracked_irq —
Simple and software-decoded IRQs.
Synopsis
void handle_untracked_irq ( | struct irq_desc * desc) ; |
Arguments
struct irq_desc * desc
the interrupt description structure for this irq
Description
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.
