NAME
       ddi_dma_addr_setup - easier DMA setup for use with virtual addresses

SYNOPSIS
       #include <sys/ddi.h>
       #include <sys/sunddi.h>

       int ddi_dma_addr_setup(dev_info_t *dip, struct as *as, caddr_t addr,
	    size_t len, uint_t flags, int (*waitfp) (caddr_t), caddr_t arg,
	    ddi_dma_lim_t * lim, ddi_dma_handle_t *handlep);

INTERFACE LEVEL
       This interface is obsolete. ddi_dma_addr_bind_handle(9F) should be used instead.

PARAMETERS
       dip	  A pointer to the device's dev_info structure.

       as	  A pointer to an address space structure. Should be set to NULL, which implies kernel address space.

       addr	  Virtual address of the memory object.

       len	  Length of the memory object in bytes.

       flags	  Flags that would go into the ddi_dma_req structure (see ddi_dma_req(9S)).

       waitfp	  The address of a function to call back later if resources aren't available now. The special function addresses DDI_DMA_SLEEP and
		  DDI_DMA_DONTWAIT (see ddi_dma_req(9S)) are taken to mean, respectively, wait until resources are available  or, do not  wait	at
		  all and do not schedule a callback.

       arg	  Argument to be passed to a callback function, if such a function is specified.

       lim	  A pointer to a DMA limits structure for this device (see ddi_dma_lim_sparc(9S) or ddi_dma_lim_x86(9S)). If this pointer is NULL,
		  a default set of DMA limits is assumed.

       handlep	  Pointer to a DMA handle. See ddi_dma_setup(9F) for a discussion of handle.

DESCRIPTION
       The ddi_dma_addr_setup() function is an interface to ddi_dma_setup(9F). It uses its  arguments  to  construct  an  appropriate  ddi_dma_req
       structure and calls ddi_dma_setup(9F) with it.

RETURN VALUES
       See ddi_dma_setup(9F) for the possible return values for this function.

CONTEXT
       The  ddi_dma_addr_setup()  can be called from user, interrupt, or kernel context, except when waitfp is set to DDI_DMA_SLEEP, in which case
       it cannot be called from interrupt context.
