* Overhaul the ACPI PCI bridge driver a bit:John Baldwin2002-08-265-589/+280
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Add an ACPI PCI-PCI bridge driver (the previous driver just handled Host-PCI bridges) that is a PCI driver that is a subclass of the generic PCI-PCI bridge driver. It overrides probe, attach, read_ivar, and pci_route_interrupt. - The probe routine only succeeds if our parent is an ACPI PCI bus which we test for by seeing if we can read our ACPI_HANDLE as an ivar. - The attach routine saves a copy of our handle and calls the new acpi_pcib_attach_common() function described below. - The read_ivar routine handles normal PCI-PCI bridge ivars and adds an ivar to return the ACPI_HANDLE of the bus this bridge represents. - The route_interrupt routine fetches the _PRT (PCI Interrupt Routing Table) from the bridge device's softc and passes it off to acpi_pcib_route_interrupt() to route the interrupt. - Split the old ACPI Host-PCI bridge driver into two pieces. Part of the attach routine and most of the route_interrupt routine remain in acpi_pcib.c and are shared by both ACPI PCI bridge drivers. - The attach routine verifies the PCI bridge is present, reads in the _PRT for the bridge, and attaches the child PCI bus. - The route_interrupt routine uses the passed in _PRT to route a PCI interrupt. The rest of the driver is the ACPI Host-PCI bridge specific bits that live in acpi_pcib_acpi.c. - We no longer duplicate pcib_maxslots but use it directly. - The driver now uses the pcib devclass instead of its own devclass. This means that PCI busses are now only children of pcib devices. - Allow the ACPI_HANDLE for the child PCI bus to be read as an ivar of the child bus. - Fetch the _PRT for routing PCI interrupts directly from our softc instead of walking the devclass to find ourself and then fetch our own softc. With this change and the new ACPI PCI bus driver, ACPI can now properly route interrupts for devices behind PCI-PCI bridges. That is, the Itanium2 with like 10 PCI busses can now boot ok and route all the PCI interrupts. Hopefully this will also fix problems people are having with CardBus bridges behind PCI-PCI bridges not properly routing interrupts when ACPI is used.

* Add an ACPI PCI bus driver that is a subclass of the generic PCI busJohn Baldwin2002-08-261-0/+235
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | driver. This driver overrides the probe, attach, and read_ivar methods. If the parent bridge is an ACPI PCI bridge, then the probe routine will match, otherwise it will fail. It tests this by seeing if it can get the ACPI_HANDLE ivar from the bridge device. In the attach routine, it uses pci_add_children() to add all the child devices (but with a slightly larger ivar so it can store ACPI_HANDLE's for child devices) and then walks through the ACPI namespace below the bus device to cache ACPI_HANDLE's for all child devices present in the namespace. It does this by comparing the pci slot and function to the address encoded in _ADR of the devices in the ACPI namespace. The read_ivar routine passes most requests off to pci_read_ivar() and adds a new request so that the ACPI_HANDLE for a child device can be read. To add proper power support the power methods can be overridden as well, but that is not currently implemented. Also, there are cases where a device may show in the ACPI namespace as a PCI device that the PCI probe does not find. Currently such devices are ignored.

* Export a few symbols as globals to allow subclassing of this driver. InJohn Baldwin2002-08-262-37/+91
| | | | | | | | | | | | | | | | OOP speak, you would mark these as 'protected' members. Specifically: - Make the pcib_softc struct public so it can be used by subclasses. - Make pcib_{read,write}_ivar(), pcib_alloc_resource(), pcib_maxslots(), and pcib_{read,write}_config() globals that can be used by subclasses. - Make the pcib devclass a global variable. - Move most of the pcib_attach() function into a global pcib_attach_common() function that can be called by the attach routines of subclasses.

* Various changes to make it easier to subclass the PCI bus device.John Baldwin2002-08-262-30/+61
| | | | | | | | | | | | | | | | | | | | | | | | | | | | - Make the pci devclass a global variable. - Add child devices in pci_attach() instead of pci_probe(). Change pci_probe() to just check for a valid bus number from the associated bridge and return -1000 if successful. This allows subclasses of the PCI bus driver to override the generic driver. - Move the code to load the vendor data into its own public function. Really though, doing this at attach is just plain wrong. This should really be done in the module load routine instead. As a side effect, the 'busno' variable in pci_attach() is now no longer static (minor bug that was harmless so far.) - Change pci_add_children() to take an extra argument that is the size of the device info structure passed to pci_read_device() and make it public so subclasses of the PCI bus can call it in their attach routines. - Move the bits to attach a probed PCI child to a PCI bus into a global pci_add_child() function. This will allow subclasses that can detect a PCI device not found in the normal PCI probe to add those devices in their own attach routine. (I have seen this in the ACPI tree on my laptop for example.) As a side effect, change the static function pci_add_resources() to get the busno, slot, and func from the passed in dinfo structure instead of requiring them as function arguments.
