501 bus driver and PCI-PCI bridge driver to allocate bus numbers for secondary
502 buses behind PCI-PCI bridges.
504 Ignore any firmware-assigned memory and I/O port resource windows in PCI-PCI
506 This forces the PCI-PCI bridge driver to allocate memory and I/O port resources
509 By default the PCI-PCI bridge driver will allocate windows that
510 contain the firmware-assigned resources devices behind the bridge.
511 In addition, the PCI-PCI bridge driver will suballocate from existing window
518 must be enabled to fully ignore firmware-supplied resource assignments.

568 Enable support for PCI-express Alternative RID Interpretation.
569 This is often used in conjunction with SR-IOV.
572 firmware-assigned memory or I/O port resources.
577 This enables decoding for such resources during bus probe.

591 MSI and MSI-X interrupts are disabled for certain chipsets known to have
592 broken MSI and MSI-X implementations when this tunable is set.
593 It can be set to zero to permit use of MSI and MSI-X interrupts if the
