There are a couple of old modifier/format sanity tests here: https://patchwork.freedesktop.org/series/46876/ Couple of things missing that now came to my mind: - test setplane/etc. rejects unsupported formats/modifiers even if addfb allowed them, exactly for the case where only a subset of planes support something - validate the IN_FORMATS blob harder, eg. make sure each modifier listed there supports at least one format. IIRC this was busted on a few drivers last year, dunno if they got fixed or not. Hmm, actually since this is now using the pre-parsed stuff I guess we should just stick an assert into igt_fill_plane_format_mod() where the blob gets parsed > > Fixes: c586f30bf74c ("drm/nouveau/kms: Add format mod prop to base/ovly/nvdisp") > Cc: James Jones <jajones@xxxxxxxxxx> > Cc: Martin Peres <martin.peres@xxxxxxx> > Cc: Jeremy Cline <jcline@xxxxxxxxxx> > Cc: Simon Ser <contact@xxxxxxxxxxx> > Cc: <stable@xxxxxxxxxxxxxxx> # v5.8+ > Signed-off-by: Lyude Paul <lyude@xxxxxxxxxx> > --- > drivers/gpu/drm/nouveau/dispnv50/wndw.c | 17 +++++++++++++---- > 1 file changed, 13 insertions(+), 4 deletions(-) > > diff --git a/drivers/gpu/drm/nouveau/dispnv50/wndw.c b/drivers/gpu/drm/nouveau/dispnv50/wndw.c > index ce451242f79e..271de3a63f21 100644 > --- a/drivers/gpu/drm/nouveau/dispnv50/wndw.c > +++ b/drivers/gpu/drm/nouveau/dispnv50/wndw.c > @@ -702,6 +702,11 @@ nv50_wndw_init(struct nv50_wndw *wndw) > nvif_notify_get(&wndw->notify); > } > > +static const u64 nv50_cursor_format_modifiers[] = { > + DRM_FORMAT_MOD_LINEAR, > + DRM_FORMAT_MOD_INVALID, > +}; > + > int > nv50_wndw_new_(const struct nv50_wndw_func *func, struct drm_device *dev, > enum drm_plane_type type, const char *name, int index, > @@ -713,6 +718,7 @@ nv50_wndw_new_(const struct nv50_wndw_func *func, struct drm_device *dev, > struct nvif_mmu *mmu = &drm->client.mmu; > struct nv50_disp *disp = nv50_disp(dev); > struct nv50_wndw *wndw; > + const u64 *format_modifiers; > int nformat; > int ret; > > @@ -728,10 +734,13 @@ nv50_wndw_new_(const struct nv50_wndw_func *func, struct drm_device *dev, > > for (nformat = 0; format[nformat]; nformat++); > > - ret = drm_universal_plane_init(dev, &wndw->plane, heads, &nv50_wndw, > - format, nformat, > - nouveau_display(dev)->format_modifiers, > - type, "%s-%d", name, index); > + if (type == DRM_PLANE_TYPE_CURSOR) > + format_modifiers = nv50_cursor_format_modifiers; > + else > + format_modifiers = nouveau_display(dev)->format_modifiers; > + > + ret = drm_universal_plane_init(dev, &wndw->plane, heads, &nv50_wndw, format, nformat, > + format_modifiers, type, "%s-%d", name, index); > if (ret) { > kfree(*pwndw); > *pwndw = NULL; > -- > 2.29.2 > > _______________________________________________ > dri-devel mailing list > dri-devel@xxxxxxxxxxxxxxxxxxxxx > https://lists.freedesktop.org/mailman/listinfo/dri-devel -- Ville Syrjälä Intel _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
