Name
       intel_vbt_decode - 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.
