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       This interface is obsolete.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 avail-
		       able  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
       ddi_dma_addr_setup()  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
       ddi_dma_addr_setup() can be called from user or interrupt context, except when waitfp is set to DDI_DMA_SLEEP, in  which  case  it  can	be
       called from user context only.
