ddi_dma_free(9f)
ddi_dma_free(9F) Kernel Functions ddi_dma_free(9F)
NAME
ddi_dma_free - release system DMA resources
SYNOPSIS
#include <sys/ddi.h>
#include <sys/sunddi.h>
int ddi_dma_free(ddi_dma_handle_t handle);
INTERFACE LEVEL
This interface is obsolete. ddi_dma_free_handle(9F) should be used
instead.
PARAMETERS
handle The handle filled in by a call to ddi_dma_setup(9F).
DESCRIPTION
The ddi_dma_free() function releases system DMA resources set up by
ddi_dma_setup(9F). When a DMA transfer completes, the driver should
free up system DMA resources established by a call to ddi_dma_set‐
up(9F). This is done by a call to ddi_dma_free(). ddi_dma_free() does
an implicit ddi_dma_sync(9F) for you so any further synchronization
steps are not necessary.
RETURN VALUES
The ddi_dma_free() function returns:
DDI_SUCCESS Successfully released resources
DDI_FAILURE Failed to free resources
CONTEXT
The ddi_dma_free() function can be called from user, interrupt, or ker‐
nel context.
