| H A D | acpi_pcib.c | diff 253426 Wed Jul 17 12:06:02 MDT 2013 jhb MFC 252576: Don't perform the acpi_DeviceIsPresent() check for PCI-PCI bridges. If we are probing a PCI-PCI bridge it is because we found one by enumerating the devices on a PCI bus, so the bridge is definitely present. A few BIOSes report incorrect status (_STA) for some bridges that claimed they were not present when in fact they were. While here, move this check earlier for Host-PCI bridges so attach fails before doing any work that needs to be torn down. PR: kern/91594 Approved by: re (marius) |
