.SH NAME
intel_reg_dumper \- Decode a bunch of Intel GPU registers for debugging
.SH SYNOPSIS
.B intel_reg_dumper [ file ]
.SH DESCRIPTION
.B intel_reg_dumper
is a tool to read and decode the values of many Intel GPU registers.  It is
commonly used in debugging video mode setting issues.  If the
.B file
argument is present, the registers will be decoded from the given file
instead of the current registers.  Use the
.B intel_reg_snapshot
tool to generate such files.
.SH ENVIRONMENT
.BR HAS_PCH_SPLIT
.PP
If set, decode as though the GPU has a PCH split.  This is only necessary for
Intel HD (Ironlake) and later register dumps in files; live decodes get this
correct automatically.
