NAME

       sys_attrs_pci - pci subsystem attributes

DESCRIPTION

       This  reference	page  lists  and  describes attributes for the PCI (pci) kernel subsystem. Refer to the sys_attrs(5) reference page for an
       introduction to the topic of kernel subsystem attributes.

       For this subsytem, users should modify only the following attribute and do so only for the purpose described. Any other visible	attributes
       cannot or should not be modified.

	      A  bit-mask  setting that allows the developer of PCI hardware and softwareto determine the PCI configuration parameters on an Alpha
	      system based on the PCI bus. By setting PCI_Developer_Debug to different values, a variety of hardware-related  or  software-related
	      information about all PCI devices on an AlphaServer are printed out at system bootstrap time. If loadable drivers are used, loadable
	      configuration data is also printed out on execution of the sysconfig -c command.

	      Refer to the /usr/include/io/dec/pci/pci_debug.h file for valid bit-field settings for this attribute.  The  pci_debug.h	file  con-
	      tains  macro definitions that state the type of information that is printed out if PCI_Developer_Debug is set to a particular value.
	      Any combination of the bit-flags is valid.  For example, the value 0x70 allows the hardware or software developer  to  see  the  PCI
	      configuration header information that the kernel reads or assigns to PCI devices.

	      Default value: 0

	      Minimum value: 0

	      Maximum value: FFFFFFFF(16)
