Name:q_alloc_generic_chip - Allocate a generic chip and initialize it*@name: Name of the irq chip*@num_ct: Number of irq_chip_type instances associated with this*@irq_base: Interrupt base nr for this chip*@reg_base: Register base address (virtual)*@handler:
Proto:struct irq_chip_generic *irq_alloc_generic_chip(const char *name, int num_ct, unsigned int irq_base, void __iomem *reg_base, irq_flow_handler_t handler)
Type:struct irq_chip_generic
Parameter:
| Type | Parameter | Name |
|---|---|---|
| const char * | name | |
| int | num_ct | |
| unsigned int | irq_base | |
| void __iomem * | reg_base | |
| irq_flow_handler_t | handler |
| 242 | sz = size of gc + num_ct * sizeof(structirq_chip_type) |
| 244 | gc = kzalloc - allocate memory. The memory is set to zero.*@size: how many bytes of memory are required.*@flags: the type of memory to allocate (see kmalloc). |
| 245 | If gc Then |
| 249 | Return gc |
