intel_vbt_decode - Intel Video BIOS Table parser

intel_vbt_decode [OPTIONS]

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.

Parse Video BIOS Tables from FILE.
Pretend to be PCI ID DEVID. Some details can be parsed more accurately if the platform is known.
Parse the details for flat panel N. Usually this is retrieved from the Video BIOS Tables, but this can be used to override.
Parse the details for all flat panels present in the Video BIOS Tables.
Hex dump the blocks.
Dump only the BIOS Data Block number N.
