NAME

       pci.ids - list of known identifiers related to PCI devices

INTRODUCTION

       Devices on the PCI bus are identified by a combination of a vendor ID (assigned by the PCI
       SIG) and device ID (assigned by the vendor). Both IDs are 16-bit integers and  the  device
       itself provides no translation to a human-readable string.

       In addition to the vendor and device, devices also report several other identifiers:

       •  Device class and subclass (two 8-bit numbers)

       •  Programming interface (8-bit number, meaning specific for the subclass)

       •  Subsystem,  which  identifies the assembly in which the device is contained.  A typical
          example is an Ethernet add-in card: the device is the Ethernet controller  chip,  while
          the  card  plays  the  role of the subsystem. Subsystems have their vendor ID (from the
          same namespace as device vendors) and subsystem  ID.  Generally,  the  meaning  of  the
          subsystem  ID depends on the device, but there are cases in which a single subsystem ID
          is used for many devices - e.g., laptop motherboards.

          The PCI utilities use the pci.ids file to translate all these numeric IDs to strings.

KEEPING THE LIST UP-TO-DATE

       The pci.ids  file  is  generated  from  the  PCI  ID  database,  which  is  maintained  at
       ⟨https://pci-ids.ucw.cz/⟩.   If  you find any IDs missing from the list, please contribute
       them to the database.

       You can use the update-pciids command to download the current version of the list.

       Alternatively, you can use lspci -q to query the database online.

FILE FORMAT

       The pci.ids file is a text file in plain ASCII, interpreted line by line.  Lines  starting
       with  the  hash  sign  are treated as comments are ignored.  Comments regarding a specific
       entry are written immediately before the entry.

       Vendor entries start with a 4-digit hexadecimal vendor ID, followed by one or more spaces,
       and the name of the vendor extending to the end of the line.

       Device  entries  are placed below the vendor entry. Each device entry consists of a single
       TAB character, a 4-digit hexadecimal device ID, followed by one or more  spaces,  and  the
       name of the device extending to the end of the line.

       Subsystem entries are placed below the device entry. They start with two TAB characters, a
       4-digit hexadecimal vendor ID (which must be defined elsewhere  in  the  list),  a  single
       space,  a  4-digit  hexadecimal  subsystem  ID,  one  or  more spaces, and the name of the
       subsystem extending to the end of the line.

       Class entries consist of "C", one space, 2-digit hexadecimal class ID, one or more spaces,
       and  the  name of the class. Subclasses are placed below the corresponding class, indented
       by a single TAB, followed by a 2-digit hexadecimal subclass ID, one or  more  spaces,  and
       the  name of the subclass.  Programming interfaces are below the subclass, indented by two
       TABs, followed by a 2-digit hexadecimal prog-if ID, one or more spaces, and the name.

       There can be device-independent subsystem IDs, although the web interface of the  database
       does  not support them yet. They start with a subsystem vendor line consisting of "S", one
       space, and a 4-digit hexadecimal vendor ID (which must correspond  to  an  already  listed
       vendor).  Subsystems  follow  on subsequent lines, each indented by one TAB, followed by a
       4-digit hexadecimal subsystem ID, one or more spaces, and the name of the subsystem.

       To ensure extensibility of the format, lines starting with an unrecognized letter followed
       by a single space are ignored and so are all following TAB-indented lines.
