GVT-g (Intel® Graphics Virtualization Technology) is a full GPU
virtualization solution with mediated pass-through support.
This tool is for create basic Linux guest based on KVMGT with
VFIO framework, it including create vgpu, create guest, check IP
address, destroy guest, remove vgpu,check dmesg log, etc functions.
v2: Treat this case as a free-standing tool, with detect & skip
when it's not running on GVT-g capable platform or running without
the required tools.
v3: Make some optimizations: like "update the generate mac address
scripts", "provide more useful information for end user", etc.
v4: Miscellaneous cleanup (Petri)

After all these years intel_bios_reader and intel_bios_dumper still
manage to confuse me. Read or dump, which one decodes. Rename
intel_bios_reader to intel_vbt_decode to be in line with the naming of
all the other tools (particularly the closely related
intel_opregion_decode tool) that decode previously gathered or dumped
information.

This is the userspace component of the Displayport Compliance
testing software required for compliance testing of the I915
Display Port driver. This must be running in order to successfully
complete Display Port compliance testing. This app and the kernel
code that accompanies it has been written to satify the requirements
of the Displayport Link CTS 1.2 rev1.1 specification from VESA.
Note that this application does not support eDP compliance testing.
This utility has an automation support for the Link training tests
(4.3.1.1. - 4.3.2.3), EDID tests (4.2.2.3
- 4.2.2.6) and Video Pattern generation tests (4.3.3.1) from CTS
specification 1.2 Rev 1.1.
This tool has the support for responding to the hotplug uevents
sent by compliance testting unit after each test.
The Linux DUT running this utility must be in text (console) mode
and cannot have any other display manager running. Since this uses
sysfs nodes for kernel interaction, this utility should be run as
Root. Once this user application is up and running, waiting for
test requests, the test appliance software on the windows host
can now be used to execute the compliance tests.
This app is based on some prior work done in April 2015 (by
Todd Previte <tprevite@gmail.com>)
v2:
* Add mode unset on hotplug uevent on disconnect (Manasi Navare)
v3:
Made capitalization consistent
Reduced line lengths
Added return value checks
Changed how GLib is linked
Fixed build warnings
v4:
* Conditionally build this tool if UDEV is present (Petri Latvala)
* igt_warn and info cleanup to remove \r
* Add intel_dp_compliance to tools/.gitignore
* Change the year in copyright statements to current (Petri Latvala)

After the recent discussions regarding the effects of the vblank
disabling policies on PC state residencies, I started running some
experiments to reevaluate some non-intuitive conclusions I had
reached. In order to help me do this, I decided to write this tool.
The idea is very simple: the tool puts the system on an screen-on idle
state, checks which PC state residency is the deepest we can reach,
measures its residency, then does some not-so-idle tests and measures
the residencies. You can use the tool to compare different Kernel
trees and you can also use the tool to compare enabled vs disabled
features.
It's obvious that these cases do not represent real-world use cases of
our driver, but they are already enough to highlight differences
between the many patches I wrote. I was even able to catch a bug in
one of my patches by spotting an unexpected regression in the
residencies.
I've been using this tool for FBC, but I expect it to also be useful
for PSR, DRRS and similar features. I've been measuring the effects of
different optimizations I wrote, and I've also been measuring the FBC
vs no-FBC cases.
It is also important to highlight that if your system is not properly
configured for efficient power savings the tool may not be able to
show differences between the results. On my Broadwell machine, for
example, if I don't run "powertop --auto-tune" before running the
tool, I get PC2 as the deepest state, and 90%+ residency for every
workload. After properly configuring the machine, I get PC7 as the
deepest state, which is the expected.
So far I only tested this tool on BDW and SKL, and it may hit some
unexpected assertions for older platforms.
I only implemented the cases that are immediately useful for me, but
we may also expand the tool in the future. We can add more important
workloads. We can add support for screen-off cases, so we can compare
the effects of runtime PM and other screen-off features. There's a lot
we can do, but none of this is on my current priority list.
And remember: /usr/bin/paste is your friend when comparing results.
v2:
- Be more idle at setup_idle().
- Improve printing for /usr/bin/paste usage.

intel_iosf_sb_read, intel_iosf_sb_write, intel_reg_dumper,
intel_reg_read, intel_reg_snapshot, intel_reg_write, intel_vga_read, and
intel_vga_write have been deprecated in favor of intel_reg. Remove the
deprecated tools. intel_reg does everything they do, and more.

This does everything the aub dump functionality in libdrm does, but
without being part of libdrm. This moves the very developer oriented
functionality out of core libdrm and adds some flexibility in how we
activate it (we can specify filename, for example). Most importantly,
this lets us dump aub files for tools and/or drivers that don't use
libdrm, without having to add that code to each of those projects.
The tool is used much like strace or valgrind. For example:
$ intel_aubdump -v --output=stuff.aub -- glxgears -geometry 500x500
will launch glxgears with its options and enable aub dumping and pass
the -v and --output=stuff.aub options to the aub dumper.

The CRC debug interface is a bit more than a simple textual file in
debugfs as there are a small command language to control what we want
from them.
This tool starts, slowly, by allowing us to dump the pipe CRCs whenever
we want. It can be handy to check what is the current CRC when we reach
a certain state on the screen (when using --interactive-debug for
instance) against a known CRC.

The tool allows you to change the panel fitter settings, so you can
change the size of the screen being displayed on your monitor without
changing the real pixel size of your desktop. The biggest use case for
this tool is to work around overscan done by TVs and some monitors in
interlaced mode.
v2: reviews by Ben, Chris and Rodrigo
- don't install
- use intel_register_access_init
- check for maximum X and Y values
- add a disclaimer saying this is not the real solution
- print less when pf is disabled and option '-l' is used

Reusing xorg code saves maintenance in the long term.
Now that m4/.gitignore is removed, the -I m4 ${ACLOCAL_FLAGS}
must be removed to avoid build breakage as m4 is generated and not
