Before this patch, handling dump files was wrong: - when HAS_PCH_SPLIT was specified, intel_reg_dumper segfaulted inside intel_check_pch() - the "devid" variable was used but not set - there was no way to specify the device id of the machine used to generate the dump file This patch fixes this behavior with the following changes: - the HAS_PCH_SPLIT variable is gone - there is now a '-d' argument that can be used to specify the device id used to interpret the results - when a dump file is used but the '-d' argument is not provided, an Ironlake machine is assumed Signed-off-by: Paulo Zanoni <paulo.r.zanoni@intel.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>

.SH NAME
|
|
intel_reg_dumper \- Decode a bunch of Intel GPU registers for debugging
|
|
.SH SYNOPSIS
|
|
.B intel_reg_dumper [ options ] [ 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.
|
|
|
|
When the
|
|
.B file
|
|
argument is present and the
|
|
.B -d
|
|
argument is not present,
|
|
.B intel_reg_dumper
|
|
will assume the file was generated on an Ironlake machine.
|
|
.SH OPTIONS
|
|
.TP
|
|
.B -d id
|
|
when a dump file is used, use 'id' as device id (in hex)
|
|
.TP
|
|
.B -h
