[PATCH i-g-t 0/7] Enable kms_flip_event_leak and kms_vblank on vc4.

[PATCH i-g-t 0/7] Enable kms_flip_event_leak and kms_vblank on vc4.

[robert.foss]

From: Robert Foss <robert.foss@collabora.com>

This series enables tests/kms_flip_event_leak and tests/kms_vblank on non-intel
hardware.
It's been tested with vc4 on an rpi2 running kernel 4.6.0-rc1.

Robert Foss (7):
  lib/igt_kms: Add support for up to 10 planes per pipe.
  lib/igt_kms: Fix plane counting in igt_display_init.
  lib/igt_kms: Make sure that default planes aren't overwritten.
  lib/igt_kms: Only move the in cursor plane for Intel hw.
  lib/igt_kms: Switch to verbose assert.
  kms_vblank: Switch from using crtc0 statically to explicitly setting
    mode.
  kms_flip_event_leak: Enable test on DRIVER_ANY.

[PATCH i-g-t 1/7] lib/igt_kms: Add support for up to 10 planes per pipe.

[robert.foss]

From: Robert Foss <robert.foss@collabora.com>

The VC4 DRM currently uses 10 planes which is more than any
other DRM, let's allocate space for the worst case scenario.

Reading more, don't we need to update stuff like kmstest_plane_name too?

[PATCH i-g-t 2/7] lib/igt_kms: Fix plane counting in igt_display_init.

[robert.foss]

From: Robert Foss <robert.foss@collabora.com>

Fix issue where the plane counting fails due to the number and
configuration of planes being unlike the intel configuration.

nitpick: I think it's more customary to call it n_planes or num_planes.

Had to read a fair bit of code to understand what's going on here, so
may make sense to add a comment.

What we might need to do is to actually make primary and cursor
dynamically assigned. Since with most drivers that's the case that
happens. Otoh we have a variable number of planes on i915 too, so not
entirely sure now what's going on here ...

Since PRIMARY and CURSOR planes are statically assigned and
that the other cases in this switch statement used the static
assignments, the loop simply makes sure the we don't overwrite
the PRIMARY or CURSOR plane.

Well primary should be first, cursor last ... Are there drivers which
register planes in a funny order that we need this? If so a comment would
be good I think.

I wasn't aware of the cursor plane always being last one.
I'll have the v2 patches reflect this.

[PATCH i-g-t 4/7] lib/igt_kms: Only move the in cursor plane for Intel hw.

[robert.foss]

From: Robert Foss <robert.foss@collabora.com>

Avoid moving the cursor plane when on non-intel hardware.
Running the move block on hardware with more than IGT_PLANE_CURSOR
number of planes causes planes do be zeroed out.

IS_INTEL takes a devid, not a fd, and its meaning is that the devid
corresponds to known hardware made by Intel.

In this case we probably want to know if the DRM driver is i915, and
for that you have is_i915_device(fd).

Reading this again, isn't the problem that on some hw there's simply no
cursor plane? With universal planes the cursor plane should alias with
some of the real planes, and we simply need to make sure that we get that
aliasing right.

But if there's no cursor registered, well there's no cursor ...

 From my point of view the problem is differentiating between the cases 
when
IGT_PLANE_CURSOR is aliasing with IGT_PLANE_4 (IGT_PLANE_3+1).

IGT_PLANE_CURSOR is assumed to be the last plane in the if statement,
which isn't the case for platform with more than 4 planes.

So identifying which platforms this assumption is true (IS_INTEL()) and
only proceeding for those platforms seemed like reasonable fix.
Maybe a more generic solution is preferable.

That's why you need to add more IGT_PLANE_x defines, to make sure _CURSOR
and the last one don't accidentally alias. Because if they do, we have a
problem.

[PATCH i-g-t 6/7] kms_vblank: Switch from using crtc0 statically to explicitly setting mode.

[robert.foss]

From: Robert Foss <robert.foss@collabora.com>

Previously crtc0 was statically used for VBLANK tests, but
that assumption is not valid for the VC4 platform.
Instead we're now explicitly setting the mode.

Also add support for testing all connected connectors during
the same test.

Annoying that we have to have so much boilerplate, but no one yet figured
out how to make this prettier. Oh well.

Ack on patches 1-6, but I didn't do a detailed review. Would be good to
get that from Tomeu or Daniel Stone.

Re: [PATCH i-g-t 6/7] kms_vblank: Switch from using crtc0 statically to explicitly setting mode.

Ok, I retract my ack. We need to extend all the places that use enum
igt_plane to correctly support more planes. And we might need to fix up
the implied assumption that a given plane can only be used on 1 crtc. But
maybe that's for a 2nd series.

Anyway I sent out a quick patch as a starting point. Please use that as
the baseline for v2.

[PATCH i-g-t 7/7] kms_flip_event_leak: Enable test on DRIVER_ANY.

[robert.foss]

From: Robert Foss <robert.foss@collabora.com>

Change DRIVER_INTEL to DRIVER_ANY to enable tests/kms_flip_event_leak
on any driver.
Switch the tiling format to something intel indenpendant.

I thought we need the same treatment of explicitly setting a mode here as
with drm_event? Or was that another one? And where's the patch to make
drm_event generic?

With my confusion about all the pending patches resolved, ack on this one
too.
