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.
REPORTING BUGS
==============
Report bugs to https://bugs.freedesktop.org.
