.SH NAME
pci_config_setup, pci_config_teardown \- setup or tear down the resources for
enabling accesses to the PCI Local Bus Configuration space
.SH SYNOPSIS
.nf
#include <sys/ddi.h>
#include <sys/sunddi.h>



\fBint\fR \fBpci_config_setup\fR(\fBdev_info_t\fR \fI*dip\fR, \fBddi_acc_handle_t\fR \fI*handle\fR);

\fBvoid\fR \fBpci_config_teardown\fR(\fBddi_acc_handle_t\fR \fI*handle\fR);
.fi

.SH INTERFACE LEVEL
illumos DDI specific (illumos DDI).
.SH PARAMETERS
.ne 2
.na
\fB\fIdip\fR \fR
.ad
.RS 11n
Pointer to the device's \fBdev_info\fR structure.
.RE

\fB\fIhandle\fR \fR
.ad
.RS 11n
Pointer to a data access handle.
.RE

.SH DESCRIPTION
\fBpci_config_setup()\fR sets up the necessary resources for enabling
subsequent data accesses to the  \fBPCI \fRLocal Bus Configuration space.
\fBpci_config_teardown()\fR reclaims and removes those resources  represented
by the data access handle returned from  \fBpci_config_setup()\fR.
.SH RETURN VALUES
\fBpci_config_setup()\fR returns:
.sp
.ne 2
.na
\fB\fBDDI_SUCCESS\fR \fR
.ad
.RS 16n
Successfully setup the resources.
.RE

.sp
.ne 2
.na
\fB\fBDDI_FAILURE\fR \fR
.ad
.RS 16n
Unable to allocate resources for setup.
.RE

.SH CONTEXT
\fBpci_config_setup()\fR must be called from user or kernel context.
\fBpci_config_teardown()\fR can be called from any context.
.SH NOTES
These functions are specific to \fBPCI \fRbus device drivers. For drivers using
these functions,  a single source to support devices with multiple bus versions
may not be easy to maintain.
