INTEL_VBT_DECODE(1)

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.
