John Baldwin 0d95597ca9 Use a more proper fix for enabling HT MSI mapping windows on Host-PCI ... bridges. Rather than blindly enabling the windows on all of them, only enable the window when an MSI interrupt is enabled for a device behind the bridge, similar to what already happens for HT PCI-PCI bridges. To implement this, each x86 Host-PCI bridge driver has to be able to locate it's actual backing device on bus 0. For ACPI, use the _ADR method to find the slot and function of the device. For the non-ACPI case, the legacy(4) driver already scans bus 0 looking for Host-PCI bridge devices. Now it saves the slot and function of each bridge that it finds as ivars that the Host-PCI bridge driver can then use in its pcib_map_msi() method. This fixes machines where non-MSI interrupts were broken by the previous round of HT MSI changes. Tested by: bapt MFC after: 1 week		2012-03-29 19:03:22 +00:00
