1 		The PCI Express Port Bus Driver Guide HOWTO
7 This guide describes the basics of the PCI Express Port Bus driver
9 register/unregister with the PCI Express Port Bus Driver.
13 3. What is the PCI Express Port Bus Driver
15 A PCI Express Port is a logical PCI-PCI Bridge structure. There
16 are two types of PCI Express Port: the Root Port and the Switch
17 Port. The Root Port originates a PCI Express link from a PCI Express
18 Root Complex and the Switch Port connects PCI Express links to
19 internal logical PCI buses. The Switch Port, which has its secondary
23 PCI Express link from the PCI Express Switch.
25 A PCI Express Port can provide up to four distinct functions,
27 PCI Express Port's services include native hotplug support (HP),
33 4. Why use the PCI Express Port Bus Driver?
36 physical device to be handled by only a single driver. The PCI
37 Express Port is a PCI-PCI Bridge device with multiple distinct
40 service drivers will compete for a single PCI-PCI Bridge device.
41 For example, if the PCI Express Root Port native hotplug service
42 driver is loaded first, it claims a PCI-PCI Bridge Root Port. The
45 drivers load and run on a PCI-PCI Bridge device simultaneously
49 having a PCI Express Port Bus driver, which manages all populated
50 PCI Express Ports and distributes all provided service requests
52 advantages of using the PCI Express Port Bus driver are listed below:
55 	  a PCI-PCI Bridge Port device.
60 	- Allow one service driver to run on multiple PCI-PCI Bridge
63 	- Manage and distribute resources of a PCI-PCI Bridge Port
66 5. Configuring the PCI Express Port Bus Driver vs. Service Drivers
68 5.1 Including the PCI Express Port Bus Driver Support into the Kernel
70 Including the PCI Express Port Bus driver depends on whether the PCI
72 automatically include the PCI Express Port Bus driver as a kernel
73 driver when the PCI Express support is enabled in the kernel.
77 PCI device drivers are implemented based on Linux Device Driver Model.
78 All service drivers are PCI device drivers. As discussed above, it is
80 PCI Express Port Bus Driver. To meet the PCI Express Port Bus Driver
85 register its service with the PCI Express Port Bus driver (see
90 the PCI Express Port Bus driver from loading a service driver.
100 necessary since these calls are executed by the PCI Port Bus driver.
160 Since all service drivers of a PCI-PCI Bridge Port device are
170 INTx emulation mode. Since service drivers of the same PCI-PCI Bridge
181 switch interrupt mode on its device. The PCI Express Port Bus driver
185 is passed in when the PCI Express Port Bus driver probes each service
194 are not permitted to switch interrupt mode on its device. The PCI
