25 22 Solaris DDI specific (Solaris DDI). This entry point is required for
26 23 non-self-identifying devices. You must write it for such devices. For
27 -self-identifying devices, \fBnulldev\fR(9F) should be specified in the
24 +self-identifying devices, \fBnulldev\fR(9F) should be specified in the
28 25 \fBdev_ops\fR(9S) structure if a probe routine is not necessary.

39 35 .SH DESCRIPTION
40 -.sp
41 -.LP
42 36 \fBprobe()\fR determines whether the device corresponding to \fIdip\fR actually
43 37 exists and is a valid device for this driver. \fBprobe()\fR is called after
44 38 \fBidentify\fR(9E) and before \fBattach\fR(9E) for a given \fIdip\fR. For
45 39 example, the \fBprobe()\fR routine can map the device registers using
46 40 \fBddi_map_regs\fR(9F) then attempt to access the hardware using
47 41 \fBddi_peek\fR(9F) or \fBddi_poke\fR(9F) and determine if the device exists.
48 42 Then the device registers should be unmapped using \fBddi_unmap_regs\fR(9F).
49 43 .sp
50 44 .LP
51 45 To probe a device that was left powered off after the last \fBdetach()\fR, it
52 46 might be necessary to power it up. If so, the driver must power up the device
53 47 by accessing device registers directly. \fBpm_raise_power\fR(9F) will be not be
54 48 available until \fBattach\fR(9E). The framework ensures that the ancestors of
55 49 the node being probed and all relevant platform-specific power management
56 50 hardware is at full power at the time that \fBprobe()\fR is called.

59 53 \fBprobe()\fR should only probe the device. It should not change any software
60 54 state and should not create any software state. Device initialization should be
61 55 done in \fBattach\fR(9E).
62 56 .sp
63 57 .LP
64 58 For a self-identifying device, this entry point is not necessary. However, if a
65 59 device exists in both self-identifying and non-self-identifying forms, a
66 60 \fBprobe()\fR routine can be provided to simplify the driver.
67 -\fBddi_dev_is_sid\fR(9F) can then be used to determine whether \fBprobe()\fR
61 +\fBddi_dev_is_sid\fR(9F) can then be used to determine whether \fBprobe()\fR
68 62 needs to do any work. See \fBddi_dev_is_sid\fR(9F) for an example.
