.SH SYNOPSIS
.sp
\fBintel_vbt_decode\fP [\fIOPTIONS\fP]
.SH DESCRIPTION
.sp
\fBintel_vbt_decode\fP is a tool to parse the Intel Video BIOS Tables (VBT) and
present the information in a human readable format.
.sp
The preferred ways of getting the binary VBT to parse are:
.INDENT 0.0
.IP 1. 3
/sys/kernel/debug/dri/0/i915_vbt (since kernel version 4.5)
.IP 2. 3
/sys/kernel/debug/dri/0/i915_opregion
.IP 3. 3
Using the \fBintel_bios_dumper(1)\fP tool.
.UNINDENT
.sp
The VBT consists of a VBT header, a BIOS Data Block (BDB) header, and a number
of BIOS Data Blocks.
.SH OPTIONS
.INDENT 0.0
.TP
.BI \-\-file\fB= FILE
Parse Video BIOS Tables from FILE.
.TP
.BI \-\-devid\fB= DEVID
Pretend to be PCI ID DEVID. Some details can be parsed more accurately if
the platform is known.
.TP
.BI \-\-panel\-type\fB= N
Parse the details for flat panel N. Usually this is retrieved from the Video
BIOS Tables, but this can be used to override.
.TP
.B \-\-all\-panels
Parse the details for all flat panels present in the Video BIOS Tables.
.TP
.B \-\-hexdump
Hex dump the blocks.
.TP
.BI \-\-block\fB= N
Dump only the BIOS Data Block number N.
