Until now we've had no unified way to handle slow/combinatorial tests.
Most of the time we don't want to run slow/combinatorial tests, so this
should remain the default, but when we do want to run such tests,
it has been handled differently in different tests.

This patch adds an --all command line option to igt_core, changes
gem_concurrent_blit and kms_frontbuffer_tracking to use this instead of
their own methods, and removes gem_concurrent_all in the process, since
it's now unnecessary.

Test cases that have subtests that should not be run by default should
use the igt_subtest_flags() / ugt_subtest_flags_f() functions and
pass the subtest types as part of the flags parameter.

v2: Incorporate various suggestions from reviewers.

v3: Rewrite to provide a generic mechanism for categorising
    the subtests

v4: Refreshed against a more recent version of i-g-t

David Weinehall (3):
  Copy gem_concurrent_all to gem_concurrent_blit
  Unify handling of slow/combinatorial tests
  Remove superfluous gem_concurrent_all.c

We'll both rename gem_concurrent_all over gem_concurrent_blit
and change gem_concurrent_blit in this changeset. To make
this easier to follow we first do the the rename.

Some subtests are not run by default, for various reasons;
be it because they're only for debugging, because they're slow,
or because they are not of high enough quality.

This patch aims to introduce a common mechanism for categorising
the subtests and introduces a flag (--all) that runs/lists all
subtests instead of just the default set.

  To: intel-gfx

When gem_concurrent_blit was converted to use the new common framework
for choosing whether or not to include slow/combinatorial tests,
gem_concurrent_all became superfluous.  This patch removes it.

I still feel that slow isn't a useful descriminant for tests. Off the
opt of my head, I would like

HANG,
SWAP,
STRESS (this is too also undefined)

that should cover the majority of the GEM cases. Looking at kms_flip
should also offer a few categories.

As for gem_concurrent_blit, I basically expect to
have h->subtest_flags | p->subtest_flags | subtest_flags.

I also expect QA to run the full gem_concurrent_blit anyway since it is
showing up regressions from over a year ago.

As I said the first time I posted this patch, I'm open to both
alternative names and help with categorising the subtests.

Yeah, I did a partial run of the full set yesterday and spotted about
150 failed tests within an hour of so. After that I had to abort the
test to continue with other work on that machine.

But it's fairly obvious that the limited set is a lot better tested.


Kind regards, David

Is the idea to also add a --test-flags interface? How is this meant to
integrate with the current BAT runtime? Also we need to figure out
how/whether we need to change the spec for how testrunners are supposed to
run igt tests. Plus obviously patch igt.py in piglit.

I think I like where this is going, but I guess needs a bit more polish
still. Integrating this into how we run/select BAT would be a great
showcase of your concept I think.

Cheers, Daniel

The idea is to also add a --test-flags interface, yes, but I deemed it
outside the scope of this patchset.

The origin of this patch is a suggestion which I believe was
from you -- to handle combinatorial tests in one unified way instead of
using various different methods (--all, vs different test invocation
names).  Since the first patch got feedback that not all excluded
subtests were because they were slow I introduced the flags concept
(the patch still classifies everything non-default as slow though,
seeing as I'd rather leave such classification to the test authors).

Since neither BAT nor piglit at the moment uses gem_concurrent_blit[1] or
kms_frontbuffer_tracking --all, I don't think there's any need to patch
either of those at this point.

Until there's some agreement on a reasonable subset of
gem_concurrent_blit subtests that can be run within at most 30 seconds,
there's no possibility to have it included in BAT or piglit -- currently
even the default set of subtests (without passing --all) will take several
hours to complete.

There are a bunch of subtests that won't complete within 30 seconds even
when run on their own[2], which obviously complicates things.

FWIW, both Skylake and Broadwell hard-hangs when running
gem_concurrent_blit --all (and up until that point spews a mighty amount
of FAIL).


Kind regards, David

[1] gem_concurrent_blit is currently not run at all due to it being too
    slow. At the very least it would be nice to have a dedicated machine
    that ran it on a daily basis.  Having weekly runs with --all should
    be a longer-term goal, but with the current hangs and massive amount
    of FAILs that is not feasible yet.

[2] Notably the "swap-*" subtests.
