| 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. |
