Hi,
I am trying to port the lnux device driver into Solaris platform.
In Solaris for allocatting dma resource, we have to set the following
set of dma attributes.
typedef struct ddi_dma_attr {
uint_t dma_attr_version; /* version number */
uint64_t dma_attr_addr_lo; /* low DMA address range */
uint64_t dma_attr_addr_hi; /* high DMA address range */
uint64_t dma_attr_count_max; /* DMA counter register */
uint64_t dma_attr_align; /* DMA address alignment */
uint_t dma_attr_burstsizes; /* DMA burstsizes */
uint32_t dma_attr_minxfer; /* min effective DMA size */
uint64_t dma_attr_maxxfer; /* max DMA xfer size */
uint64_t dma_attr_seg; /* segment boundary */
int dma_attr_sgllen; /* s/g length */
uint32_t dma_attr_granular; /* granularity of device */
uint_t dma_attr_flags; /* Bus specific DMA flags */
} ddi_dma_attr_t;
And most of these attribute values are specific to the device.
But I couldn't find out the corresponding structure/functionality in Linux.
Please guide me.
Regards,
Nabil
