, have been changed. Drivers that use these data structures should make sure that these fields are being used appropriately. The data structures and the fields that were changed in a significant way are listed below.
| buf(9S) |
| size_t |
b_bcount; |
/* was type unsigned int */ |
| size_t |
b_resid; |
/* was type unsigned int */ |
| size_t |
b_bufsize; |
/* was type long */ |
| |
| The fields changed here pertain to transfer size, which can now exceed more than 4GB in future systems. |
| |
| ddi_dma_attr(9S) |
| This structure defines attributes of the DMA engine and the device. Because these attributes specify register sizes, fixed-width data types have been used instead of fundamental types. |
| |
| ddi_dma_cookie(9S) |
| uint32_t |
dmac_address; |
/* was type unsigned long */ |
| size_t |
dmac_size; |
/* was type u_int */ |
| |
| This structure contains a 32-bit DMA address, so a fixed-width data type has been used to define it. The size has been redefined as size_t. |
| |
| scsi_arq_status(9S) |
| u_int |
sts_rqpkt_state; |
/* was type u_long */ |
| u_int |
sts_rqpkt_statistics; |
/* was type u_long */ |
| |
| These fields do not need to grow and have been redefined as 32-bit quantities. |
| |
| scsi_pkt(9S) |
| u_int |
pkt_flags; |
/* was type u_long */ |
| int |
pkt_time; |
/* was type long */ |
| ssize_t |
pkt_resid; |
/* was type long */ |
| u_int |
pkt_state; |
/* was type u_long */ |
| u_int |
pkt_statistics; |
/* was type u_long */ |
| |
| Because the flags, state, and statistics fields do not need to grow, they have been redefined as 32-bit integers. The data transfer size pkt_resid field does grow and has been redefined as ssize_t. |
