The following table shows the PCI functions.
| Programming Element | Description |
|---|---|
| OALPCICfgRead | This function reads the PCI configuration space. |
| OALPCICfgWrite | This function writes to the PCI configuration space. |
| OALPCIConfig | This function provides simple PCI bus configuration. It configures the PCI bus device resources. |
| OALPCIDumpConfig | This function is a helper function that dumps configuration information for a specific device. |
| OALPCIDump | This function is a helper function that dumps full PCI bus information for all the devices on the bus. |
| OALPCIFindNextId | This function searches the PCI bus for cards that match the device ID. |
| OALPCIGetHeaderType | This function is a helper function used by the KITL to read the header type in a PCI bus configuration register. |
| OALPCIGetId | This function is a helper function used by the KITL to read specific configuration registers. |
| OALPCIGetInterruptPin | This function is a helper function used by the KITL to read the interrupt pin in a PCI bus configuration register. |
| OALPCIGetMBAR | This function is a helper function used by the KITL to read the memory-based address register (MBAR) in a PCI bus configuration register. |
| OALPCIGetSecBusNum | This function is a helper function used by the KITL to read the secondary bus number in a PCI bus configuration register. |
| OALPCIGetSubBusNum | This function is a helper function used by the KITL to read the subordinate bus number in a PCI bus configuration register. |
| OALPCIInit | This function initializes the PCI module. It is called from the OEMInit function to initialize the PCI bus. |
| OALPCIPowerOff | This function prepares the PCI hardware to be powered off or suspended. |
| OALPCIPowerOn | This function powers on the PCI hardware, restores the PCI clock, and issues a PCI bus reset. |
| OALPCIRegisterAsUsed | This function registers the KITL device as used in the OS registry. |
| OALPCITransBusAddress | This function translates the PCI bus-relative address to the CPU address space. |
