[PATCH i-g-t 0/3] IGT support for nuclear pageflip

[PATCH i-g-t 0/3] IGT support for nuclear pageflip

[Matt Roper]

These patches add support for nuclear pageflip to the IGT testsuite to help
exercise the kernel patches just posted.

Note that nuclear pageflip (and eventually full atomic modeset) support
requires a very new libdrm that hasn't yet gone upstream; you can find a copy
in Rob Clark's repo here:
        https://github.com/robclark/libdrm.git atomic

All of the nuclear/atomic code is contained inside #ifdef blocks managed by
autoconf, so everything should continue to work properly if you build/run
against an older libdrm that does not have atomic support.

The actual kms_nuclear test added here is a quick copy/paste of parts of the
universal_plane test; it's enough to exercise the nuclear interface and sanity
test that things are hooked up, but it will definitely need to be signficantly
extended to try out all of the corner cases before I'd really consider it
"done."

[PATCH i-g-t 1/3] lib/kms: Let display commits wait for keypress while debugging

[Matt Roper]

Add a call to igt_debug_wait_for_keypress() immediately before we commit
new hardware state to help simplify display debugging.

To use this, just set the environment variable:

        IGT_DEBUG_INTERACTIVE=commit

[PATCH i-g-t 2/3] lib/kms: Add nuclear pageflip commit style

[Matt Roper]

This commit style only covers the "nuclear pageflip" subset of the
atomic API (i.e., single CRTC, plane updates only).  In the future when
our kernel driver has full atomic modeset support, we'll add another
commit style 'atomic' which will re-use the same plane commit calls
added here, but will generate and commit property sets in the display's
commit handler rather than the output's commit handler.

Since nuclear pageflip (and full atomic eventually) depend on very new
(currently unreleased) libdrm, use autoconf to check for support so that
we can still run with just legacy + universal styles when built with
older libdrm's.

Need to include config.h in the header file, otherwise code that depends
on the size of igt_output_t on the tests might do the wrong thing.

want to expand upon this in the future, but this is a good starting

Using data.display here means that --list-subtests doesn't list any
subtests. The igt_fixture blocks (and the subtests themselves) are not
run when enumerating subtests, which means data.display is not
initialised.

[PATCH i-g-t 3/3] tests: Introduce kms_nuclear (v2)

[Matt Roper]

A very simple testcase to exercise nuclear pageflip.  We'll definitely
want to expand upon this in the future, but this is a good starting
point to sanity check nuclear pageflip support.

v2:
 - Add IGT_TEST_DESCRIPTION() (Thomas Wood)
 - Don't use fixture-generated pipe number for main loop since this will
   prevent proper test enumeration.  Just assume three pipes for the
   main loop and skip inside the tests if we have fewer. (Thomas Wood)
 - Add to .gitignore (Thomas Wood)
