.Sh SYNOPSIS
|
|
.Cd "rdcpcib* at pci? dev ? function ?"
|
|
.Cd "isa0 at rdcide?"
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
driver supports the PCI/ISA bridge and watchdog timer as found in RDC's
|
|
vortex86 and PMX-1000 system on chip.
|
|
The watchdog timer may be configured for expiration periods between one and
|
|
512 seconds.
|
|
.Sh DIAGNOSTIC
|
|
.Bl -diag
|
|
.It "rdcpcib0: watchdog fired bit set, clearing"
|
|
A bit was set in the watchdog's timer registers indicating that it has reached
|
|
the configured timeout at last once.
|
|
This probably means this boot has been triggered by a watchdog timeout.
