intel_vbt_decode ā€” Intel Video BIOS Table parser

Synopsis

intel_vbt_decode [Options]

Description

intel_vbt_decode is a tool to parse the Intel Video BIOS Tables (VBT) and present the information in a human readable format.

The preferred ways of getting the binary VBT to parse are:

  1. /sys/kernel/debug/dri/0/i915_vbt (since kernel version 4.5)
  2. /sys/kernel/debug/dri/0/i915_opregion
  3. Using the intel_bios_dumper(1) tool.

The VBT consists of a VBT header, a BIOS Data Block (BDB) header, and a number of BIOS Data Blocks.

Options

--file=FILE

Parse Video BIOS Tables from FILE.

--devid=DEVID

Pretend to be PCI ID DEVID. Some details can be parsed more accurately if the platform is known.

--panel-type=N

Parse the details for flat panel N. Usually this is retrieved from the Video BIOS Tables, but this can be used to override.

--all-panels

Parse the details for all flat panels present in the Video BIOS Tables.

--hexdump

Hex dump the blocks.

--block=N

Dump only the BIOS Data Block number N.
