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.
