ENUM IRQ_GC_FLAGS(9) Structures ENUM IRQ_GC_FLAGS(9)

NAME

enum_irq_gc_flags - Initialization flags for generic irq chips

SYNOPSIS

enum irq_gc_flags {
  IRQ_GC_INIT_MASK_CACHE,
  IRQ_GC_INIT_NESTED_LOCK,
  IRQ_GC_MASK_CACHE_PER_TYPE,
  IRQ_GC_NO_MASK
};

CONSTANTS

IRQ_GC_INIT_MASK_CACHE
Initialize the mask_cache by reading mask reg
IRQ_GC_INIT_NESTED_LOCK
Set the lock class of the irqs to nested for irq chips which need to call irq_set_wake on the parent irq. Usually GPIO implementations
IRQ_GC_MASK_CACHE_PER_TYPE
Mask cache is chip type private
IRQ_GC_NO_MASK
Do not calculate irq_data->mask
