NAME

6       intel_vbt_decode - Intel Video BIOS Table parser
7

SYNOPSIS

9       intel_vbt_decode [OPTIONS]
10

DESCRIPTION

12       intel_vbt_decode  is  a tool to parse the Intel Video BIOS Tables (VBT)
13       and present the information in a human readable format.
14
15       The preferred ways of getting the binary VBT to parse are:
16
17       1. /sys/kernel/debug/dri/0/i915_vbt (since kernel version 4.5)
18
19       2. /sys/kernel/debug/dri/0/i915_opregion
20
21       3. Using the intel_bios_dumper(1) tool.
22
23       The VBT consists of a VBT header, a BIOS Data Block (BDB) header, and a
24       number of BIOS Data Blocks.

OPTIONS

27       --file=FILE
28              Parse Video BIOS Tables from FILE.
29
30       --devid=DEVID
31              Pretend  to be PCI ID DEVID. Some details can be parsed more ac‐
32              curately if the platform is known.
33
34       --panel-type=N
35              Parse the details for flat panel N. Usually  this  is  retrieved
36              from the Video BIOS Tables, but this can be used to override.
37
38       --all-panels
39              Parse  the details for all flat panels present in the Video BIOS
40              Tables.
41
42       --hexdump
43              Hex dump the blocks.
44
45       --block=N
46              Dump only the BIOS Data Block number N.
