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
|
||
|
|
