HANDLE_UNTRACKED_IRQ(9) Public Functions Provided HANDLE_UNTRACKED_IRQ(9)

NAME

handle_untracked_irq - Simple and software-decoded IRQs.

SYNOPSIS

void handle_untracked_irq(struct irq_desc * desc);

ARGUMENTS

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.
