From c2778357234f84668eab5558b54ad28478439d0b Mon Sep 17 00:00:00 2001 From: Andrew Patterson Date: Tue, 22 Jan 2008 17:18:12 -0700 Subject: PCI ACPI: Added a function to register _OSC with only PCIe devices. The function pci_osc_support_set() traverses every root bridge when checking for _OSC support for a capability. It quits as soon as it finds a device/bridge that doesn't support the requested capability. This won't work for systems that have mixed PCI and PCIe bridges when checking for PCIe features. I split this function into two -- pci_osc_support_set() and pcie_osc_support_set(). The latter is used when only PCIe devices should be traversed.
