Reads from or write to a given location in the PCI configuration space.
PeiServices | An indirect pointer to the PEI Services Table published by the PEI Foundation. | |
This | Pointer to local data for the interface. | |
Width | The width of the access. Enumerated in bytes. See EFI_PEI_PCI_CFG_PPI_WIDTH above. | |
Address | The physical address of the access. The format of the address is described by EFI_PEI_PCI_CFG_PPI_PCI_ADDRESS. | |
Buffer | A pointer to the buffer of data.. |
EFI_SUCCESS | The function completed successfully. | |
EFI_DEVICE_ERROR | There was a problem with the transaction. | |
EFI_DEVICE_NOT_READY | The device is not capable of supporting the operation at this time. |

Performs a read-modify-write operation on the contents from a given location in the PCI configuration space.
PeiServices | An indirect pointer to the PEI Services Table published by the PEI Foundation. | |
This | Pointer to local data for the interface. | |
Width | The width of the access. Enumerated in bytes. Type EFI_PEI_PCI_CFG_PPI_WIDTH is defined in Read(). | |
Address | The physical address of the access. | |
SetBits | Points to value to bitwise-OR with the read configuration value. |
ClearBits | Points to the value to negate and bitwise-AND with the read configuration value. The size of the value is determined by Width. |
EFI_SUCCESS | The function completed successfully. | |
EFI_DEVICE_ERROR | There was a problem with the transaction. | |
EFI_DEVICE_NOT_READY | The device is not capable of supporting the operation at this time. |
