CONFIG_PCI_CNB20LE_QUIRK: Read PCI host bridge windows from the CNB20LE chipset

General informations

The Linux kernel configuration item CONFIG_PCI_CNB20LE_QUIRK has multiple definitions:

Read PCI host bridge windows from the CNB20LE chipset found in arch/x86/Kconfig

The configuration item CONFIG_PCI_CNB20LE_QUIRK:

Help text

Read the PCI windows out of the CNB20LE host bridge. This allows PCI hotplug to work on systems with the CNB20LE chipset which do not have ACPI.

The ServerWorks (later Broadcom) CNB20LE was a chipset designed most probably only for Pentium III.

To find out if you have such a chipset, search for a PCI device with 1166:0009 PCI IDs, for example by executing lspci -nn | grep '1166:0009' The code is inactive if there is none.

There's no public spec for this chipset, and this functionality is known to be incomplete.

You should say N unless you know you need this.
