pci_config_setup(9F) Kernel Functions for Drivers pci_config_setup(9F)NAME
pci_config_setup, pci_config_teardown - setup or tear down the
resources for enabling accesses to the PCI Local Bus Configuration
space
SYNOPSIS
#include <sys/ddi.h>
#include <sys/sunddi.h>
int pci_config_setup(dev_info_t *dip, ddi_acc_handle_t *handle);
void pci_config_teardown(ddi_acc_handle_t *handle);
INTERFACE LEVEL
Solaris DDI specific (Solaris DDI).
PARAMETERS
dip Pointer to the device's dev_info structure.
handle Pointer to a data access handle.
DESCRIPTIONpci_config_setup() sets up the necessary resources for enabling subse‐
quent data accesses to the PCI Local Bus Configuration space. pci_con‐
fig_teardown() reclaims and removes those resources represented by the
data access handle returned from pci_config_setup().
RETURN VALUESpci_config_setup() returns:
DDI_SUCCESS Successfully setup the resources.
DDI_FAILURE Unable to allocate resources for setup.
CONTEXTpci_config_setup() must be called from user or kernel context. pci_con‐
fig_teardown() can be called from any context.
NOTES
These functions are specific to PCI bus device drivers. For drivers
using these functions, a single source to support devices with multi‐
ple bus versions may not be easy to maintain.
