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> #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);
Solaris DDI specific (Solaris DDI).
Pointer to the device's dev_info structure.
Pointer to a data access 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:
Successfully setup the resources.
Unable to allocate resources for setup.
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.
