This tool serves as a wrapper around the constructs provided by the
drm_dpcd_aux_dev kernel module by working on the /dev/drm_dp_aux[n]
devices created by the kernel module.
It supports reading and writing dpcd registers on the connected aux
channels.
In the follow-up patch, support for decoding these registers will be
added to facilate debugging panel related issues.
v2: (Fixes by Rodrigo but no functional changes yet):
- Indentations, Typo, Missed spaces
- Removing mentioning to decode and spec that is not implemented yet.
- Add Makefile.sources back
- Missed s/printf/igt_warn
v3:
- Address DK's review comments from v2 above.
- Squash Rodrigo's file handling unification patch.
- Make count, offset and device id optional.
v4:
- Better error handling and refactoring.

Cannonlake port clock programming tests and verifies DPLL legal dividers
P, Q, and K. This tests adds two reference clocks 19.2MHz and 24MHz to
test algorithm's capability to find P, Q, and K dividers as well as DCO
frequency for different symbol clock rates.
The test compares two algorithms, the reference with double precision and
i915 implementation with fixed point precision. In case of a difference in
computation the difference on dividers is printed out to the screen.

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.

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

intel_opregion_decode tool) that decode previously gathered or dumped

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)

then dump them to file.
The logs are pulled from a debugfs file '/sys/kernel/debug/dri/guc_log' and
by default stored into a file 'guc_log_dump.dat'. The name, including the
location, of the output file can be changed through a command line argument.
The utility goes into an infinite loop where it waits for the arrival of new
logs and as soon as new set of logs are produced it captures them in its local
buffer which is then flushed out to the file on disk.
Any time when logging needs to be ended, User can stop this utility (CTRL+C).
Before entering into a loop, it first discards whatever logs are present in
the debugfs file.
This way User can first launch this utility and then start a workload/activity
for which GuC firmware logs are to be actually captured and keep running the
utility for as long as its needed, like once the workload is over this utility
can be forcefully stopped.
If the logging wasn't enabled on GuC side by the Driver at boot time, utility
will first enable the logging and later on when it is stopped (CTRL+C) it will
also pause the logging on GuC side.
v2:
- Use combination of alarm system call & SIGALRM signal to run the utility
for required duration. (Tvrtko)
- Fix inconsistencies, do minor cleanup and refactoring. (Tvrtko)
v3:
- Fix discrepancy for the output file command line option and update the
Usage/help string.
v4:
- Update the exit condition for flusher thread, now will exit only after
the capture loop is over and not when the flag to stop logging is set.
This handles a corner case, due to which the dump of last captured buffer
was getting missed.
- Add a newline character at the end of assert messages.
- Avoid the assert for the case, which occurs very rarely, when there are no
bytes read from the relay file.

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.

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.

WARNING: very minimally tested
In general you should not need this tool. Its primary purpose is for
benchmarking, and for debugging performance issues.
For many kernel releases now sysfs has supported reading and writing the GPU
frequency. Therefore, this tool provides no new functionality. What it does
provide is an easy to package (for distros) tool that handles the most common
scenarios.
