pci.ids - list of known identifiers related to PCI devices
Вступление (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.
Формат файла (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.
