STRUCT IRQ_CHIP_GENE(9) Structures STRUCT IRQ_CHIP_GENE(9)NAME
struct_irq_chip_generic - Generic irq chip data structure
SYNOPSIS
struct irq_chip_generic {
raw_spinlock_t lock;
void __iomem * reg_base;
unsigned int irq_base;
unsigned int irq_cnt;
u32 mask_cache;
u32 type_cache;
u32 polarity_cache;
u32 wake_enabled;
u32 wake_active;
unsigned int num_ct;
void * private;
struct list_head list;
struct irq_chip_type chip_types[0];
};
MEMBERS
lock
Lock to protect register and cache data access
reg_base
Register base address (virtual)
irq_base
Interrupt base nr for this chip
irq_cnt
Number of interrupts handled by this chip
mask_cache
Cached mask register
type_cache
Cached type register
polarity_cache
Cached polarity register
wake_enabled
Interrupt can wakeup from suspend
wake_active
Interrupt is marked as an wakeup from suspend source
num_ct
Number of available irq_chip_type instances (usually 1)
private
Private data for non generic chip callbacks
list
List head for keeping track of instances
chip_types[0]
Array of interrupt irq_chip_types
DESCRIPTION
Note, that irq_chip_generic can have multiple irq_chip_type implementations which can be associated to a particular irq line of an
irq_chip_generic instance. That allows to share and protect state in an irq_chip_generic instance when we need to implement different flow
mechanisms (level/edge) for it.
