The only sane way I can see gem_create returning -EINVAL is if the test is trying to create a zero sized object, so doesn't sound like a gem bug...

Thanks for commenting! Do you think you could you check the IGT code? I know this is a KMS test, but the GEM call comes from the lib/, so this is something your team should co-own and there may be a bug there.

kms_available_modes_crc.c, setup_fb():

        mode = igt_output_get_mode(output);
        if (plane->type != DRM_PLANE_TYPE_CURSOR) {
                w = mode->hdisplay;
                h = mode->vdisplay;
                tiling = LOCAL_I915_FORMAT_MOD_X_TILED;
        } 

is the source.

I think problem part is this piece of code in kms_available_modes_crc.c, setup_fb():

	switch (fillers[i].bpp) {
	case NV12:
	case BYTES_PP_1:
		bpp = 8;
		break;

	case P010:
	case BYTES_PP_2:
		bpp = 16;
		break;

	case SKIP4:
	case BYTES_PP_4:
		bpp = 32;
		break;
	}

it's missing default case and leave 'bpp' to zero. To me it look like correct fix is to change in table 'fillers' last element from 

	{ 0, 0, 0, 0 }

to

	{ 0, 0, SKIP4, 0 }

I think this change will fix bug that would follow from creating default case.

Waiting for CI results but I think this patch will fix this issue:

This failure needs a separate bug?

Yes. This bug is about error in kms_available_modes_crc which cannot affect kms_plane_lowres. Though, reading comment #4 there is most likely similar bug in kms_plane_lowres where is asked to create zero size object.

Linked report has absolutely nothing to do with this bug.

This bug is about error in available_modes_crc test while linked report has dmesg talking about powerwells before if fails.
