| What: /sys/bus/pci/drivers/.../bind |
| Date: December 2003 |
| Contact: linux-pci@vger.kernel.org |
| Description: |
| Writing a device location to this file will cause |
| the driver to attempt to bind to the device found at |
| this location. This is useful for overriding default |
| bindings. The format for the location is: DDDD:BB:DD.F. |
| That is Domain:Bus:Device.Function and is the same as |
| found in /sys/bus/pci/devices/. For example: |
| # echo 0000:00:19.0 > /sys/bus/pci/drivers/foo/bind |
| (Note: kernels before 2.6.28 may require echo -n). |

| Description: |

| What: /sys/bus/pci/drivers/.../new_id |
| Date: December 2003 |
| Contact: linux-pci@vger.kernel.org |
| Description: |
| Writing a device ID to this file will attempt to |
| dynamically add a new device ID to a PCI device driver. |
| This may allow the driver to support more hardware than |
| was included in the driver's static device ID support |
| table at compile time. The format for the device ID is: |
| VVVV DDDD SVVV SDDD CCCC MMMM PPPP. That is Vendor ID, |
| Device ID, Subsystem Vendor ID, Subsystem Device ID, |
| Class, Class Mask, and Private Driver Data. The Vendor ID |
| and Device ID fields are required, the rest are optional. |
| Upon successfully adding an ID, the driver will probe |
| for the device and attempt to bind to it. For example: |
| # echo "8086 10f5" > /sys/bus/pci/drivers/foo/new_id |

| What: /sys/bus/pci/devices/.../vpd |
| Date: February 2008 |
| Contact: Ben Hutchings <bhutchings@solarflare.com> |
| Description: |
| A file named vpd in a device directory will be a |
| binary file containing the Vital Product Data for the |
| device. It should follow the VPD format defined in |
| PCI Specification 2.1 or 2.2, but users should consider |
| that some devices may have malformatted data. If the |
| underlying VPD has a writable section then the |
| corresponding section of this file will be writable. |
