ddi_dma_addr_setup(9f)
ddi_dma_addr_setup(9F) Kernel Functions ddi_dma_addr_setup(9F)
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This interface is obsolete.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 discus‐
sion 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.
