pci_config_setup, pci_config_teardown - setup or tear down the resources for enabling accesses to the PCI Local Bus Configuration space

#include <sys/ddi.h>

int pci_config_setup(dev_info_t *dip, ddi_acc_handle_t *handle);

void pci_config_teardown(ddi_acc_handle_t *handle);

illumos DDI specific (illumos DDI). dip handle pci_config_setup() sets up the necessary resources for enabling subsequent data accesses to the PCI Local Bus Configuration space. pci_config_teardown() reclaims and removes those resources represented by the data access handle returned from pci_config_setup(). pci_config_setup() returns: DDI_SUCCESS DDI_FAILURE pci_config_setup() must be called from user or kernel context. pci_config_teardown() can be called from any context. These functions are specific to PCI bus device drivers. For drivers using these functions, a single source to support devices with multiple bus versions may not be easy to maintain.
