.SH NAME
intel_reg_dumper \- Decode a bunch of Intel GPU registers for debugging
.SH SYNOPSIS
-.B intel_reg_dumper
+.B intel_reg_dumper [ file ]
.SH DESCRIPTION
-.B intel_reg_write
+.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.
+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.

+.SH NAME
+intel_reg_snapshot \- Take a GPU register snapshot
+.SH SYNOPSIS

+.SH DESCRIPTION
+.B intel_reg_snapshot
+takes a snapshot of the registers of an Intel GPU, and writes it to standard
+output. These files can be inspected later with the

+tool.
