[igt-dev] [PATCH i-g-t v2 0/5] Add nouveau-crc tests

[Lyude]

From: Lyude Paul <lyude@redhat.com>

Nouveau has finally gotten CRC support, hooray! Well, it's under review
at least:

https://patchwork.freedesktop.org/series/74804/
(it has a cover letter, but nouveau's mailing list configuration has
blocked the email so I'm waiting for a moderator to fix that)

So, this series adds the relevant tests for it since nvidia's CRC
implementation has some rather interesting design choices that needed to
be worked around.

Changes since v1:
* fix documentation errors Petri pointed out
* Fix documentation for igt_require_fd()
* Fix copyright year in tests/nouveau_crc.c

Lyude Paul (5):
  lib/igt_core: Fix igt_assert_fd() documentation
  lib/igt_core: Add igt_require_fd()
  lib/igt_debugfs: Add igt_debugfs_pipe_dir()

[Lyude]

From: Lyude Paul <lyude@redhat.com>

As Petri Latvala pointed out, some of the documentation in this macro is
mistakenly copied from the other igt_assert*() macros. Let's fix that.

[igt-dev] [PATCH i-g-t v2 4/5] lib/igt_kms: Hook up connector dithering prop

[Lyude]

From: Lyude Paul <lyude@redhat.com>

Nvidia display hardware provides a set of flexible dithering options for
CRTCs. This dithering is actually noticeable in the CRC output for all
available tap points, and can be seen as CRC values for identical frames
cycling between either 2 or 4 values repeatedly (each one of these
values is a different dithering phase applied to the source output). Of
course, this is very likely to break tests using CRC readback since we
don't expect the CRC to change if the source content hasn't changed.

So, hook up support for configuring the dithering property and reset it
to off from igt_display_reset() when applicable.

[igt-dev] [PATCH i-g-t v2 5/5] tests: Add nouveau-crc tests

[Lyude]

From: Lyude Paul <lyude@redhat.com>

We're finally getting CRC support in nouveau, so let's start testing
this in igt as well! While the normal CRC capture tests are nice,
there's a number of Nvidia-specific hardware characteristics that we
need to test as well.

The most important one is known as a "notifier context flip". Basically,
Nvidia GPUs store generated CRCs in an allocated memory region, referred
to as the notifier context, that the driver programs itself. Strangely,
this region can only hold a limited number of CRC entries, and once it
runs out of available entries the hardware simply sets an overrun bit
and stops writing any new CRC entries.

Since igt-gpu-tools doesn't really have an expectation of only being
able to grab a limited number of CRCs, we work around this in nouveau by
allocating two separate CRC notifier regions each time we start
capturing CRCs, and then flip between them whenever we get close to
filling our currently programmed notifier context. While this keeps the
number of CRC entries we lose to an absolute minimum, we are guaranteed
to lose exactly one CRC entry between context flips. Thus, we add some
tests to ensure that nouveau handles these flips correctly
(pipe-[A-F]-ctx-flip-detection), and that igt itself is also able to
handle them correctly (pipe-[A-F]-ctx-flip-skip-current-frame). Since
these tests use a debugfs interface to manually control the notifier
context flip threshold, we also add one test to ensure that any flip
thresholds we set are cleared after a single CRC capture
(ctx-flip-threshold-reset-after-capture).

In addition, we also add some simple tests to test Nvidia-specific CRC
sources.

Changes since v1:
* Fix copyright year in nouveau_crc.c
