Macro Definition Documentation

MTIVOR

#define MTIVOR	(		vec,
			offset
	)

Value:

    offset += VECTOR_TABLE_ENTRY_SIZE; \
  } while (0)

Function Documentation

bsp_fdt_map_intr()

uint32_t bsp_fdt_map_intr	(	const uint32_t *	intr,
		size_t	icells
	)

Maps the interrupt number of the FDT to the interrupt vector used by the interrupt management.

This function is used by the libbsd to implement the OFW_BUS_MAP_INTR bus method.

Parameters

[in]	intr	The FDT interrupt number cells.
[in]	icells	The FDT interrupt cell count.

Returns

The interrupt vector of the FDT interrupt number.
