Some of the DDI functions argument data types have been changed. These routines are listed below.
struct buf *getrbuf(int sleepflag);In previous releases, sleepflag was defined as a type long.
int drv_getparm(unsigned int parm, void *value_p);In previous releases, value_p was defined to be type unsigned long *.
In the 64-bit kernel, drv_getparm(9F) can be used to fetch quantities that are both 32-bit and 64-bit, yet the interface does not define the data types of these quantities which encourages simple programming errors.
clock_t ddi_get_lbolt(void); time_t ddi_get_time(void); cred_t *ddi_get_cred(void); pid_t ddi_get_pid(void);Driver writers are strongly urged to use these routines instead of drv_getparm(9F).
void delay(clock_t ticks); timeout_id_t timeout(void (*func)(caddr_t), caddr_t arg, clock_t ticks);The ticks argument to both of these routines has been changed from long to clock_t.
struct map *rmallocmap(size_t mapsize); struct map *rmallocmap_wait(size_t mapsize);The mapsize argument to both of these routines has been changed from ulong_t to size_t.
struct buf *scsi_alloc_consistent_buf(struct scsi_address *ap, struct buf *bp, size_t datalen, uint_t bflags, int (*callback )(caddr_t), caddr_t arg);In previous releases, datalen was defined as an int and bflags was defined as a ulong.
int uiomove(caddr_t address, size_t nbytes, enum uio_rw rwflag, uio_t *uio_p);The nbytes argument was defined as a type long, but since it represents a size in bytes, size_t is more appropriate.
int cv_timedwait(kcondvar_t *cvp, kmutex_t *mp, clock_t timeout); int cv_timedwait_sig(kcondvar_t *cvp, kmutex_t *mp, clock_t timeout);In previous releases, the timeout argument to both of these routines was defined to be of type long. Since they represent time in ticks, clock_t is more appropriate.
int ddi_device_copy(ddi_acc_handle_t src_handle, caddr_t src_addr, ssize_t src_advcnt, ddi_acc_handle_t dest_handle, caddr_t dest_addr, ssize_t dest_advcnt, size_t bytecount, uint_t dev_datasz);The src_advcnt, dest_advcnt, dev_datasz arguments have changed type. These were previously defined as long, long and ulong_t respectively.
int ddi_device_zero(ddi_acc_handle_t handle, caddr_t dev_addr, size_t bytecount, ssize_t dev_advcnt, uint_t dev_datasz):In previous releases, dev_advcnt was defined as a type long and dev_datasz as a ulong_t.
int ddi_dma_mem_alloc(ddi_dma_handle_t handle, size_t length, ddi_device_acc_attr_t *accattrp, uint_t flags, int (*waitfp)(caddr_t), caddr_t arg, caddr_t *kaddrp, size_t *real_length, ddi_acc_handle_t *handlep);In previous releases, length, flags and real_length were defined with types, uint_t, ulong_t and uint_t *.
