INTERFACE LEVEL

31       The  functions described here are obsolete. For the outb(), outw(), and
32       outl() functions use,  respectively,  ddi_put8(9F),  ddi_put8(9F),  and
33       ddi_put8(9F)  instead.  For repoutsb(), repoutsw(), andrepoutsl(), use,
34       respectively, ddi_rep_put8(9F), ddi_rep_put8(9F), and  ddi_rep_put8(9F)
35       instead.
36

PARAMETERS

38       port     A valid I/O port address.
39
40
41       value    The data to be written to the I/O port.
42
43
44       addr     The address of a buffer from which the values will be fetched.
45
46
47       count    The number of values to be written to the I/O port.

DESCRIPTION

51       These  routines  write  data  of various sizes to the I/O port with the
52       address specified by port.
53
54
55       The outb(), outw(), and outl() functions write 8 bits, 16 bits, and  32
56       bits of data respectively, writing the data specified by value.
57
58
59       The  repoutsb(),  repoutsw(),  and  repoutsd() functions write multiple
60       8-bit, 16-bit, and 32-bit values,  respectively.  count  specifies  the
61       number  of  values  to  be  written. addr is a pointer to a buffer from
62       which the output values are fetched.
63

CONTEXT

65       These functions may be called from user, interrupt, or kernel context.
