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 
      #include 



     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.


DESCRIPTION
     pci_config_setup() sets up the necessary resources for  ena-
     bling  subsequent data accesses to the  PCI Local Bus Confi-
     guration space. pci_config_teardown() reclaims  and  removes
     those  resources   represented  by  the  data  access handle
     returned from  pci_config_setup().

RETURN VALUES
     pci_config_setup() returns:

     DDI_SUCCESS     Successfully setup the resources.


     DDI_FAILURE     Unable to allocate resources for setup.


CONTEXT
     pci_config_setup() must be called from user or  kernel  con-
     text. pci_config_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 multiple bus versions may not be easy to  main-
     tain.
