That's an argument I'm willing to live with -- can you generate such a patch without your previous patch? However if we do this, this is basically saying that MSAA will never work on nv3x/nv4x, since it's unlikely that anyone will look further into it. It'd be nice to put a little effort in first to make sure there isn't something simple we can fix. > > Signed-off-by: Hans de Goede <hdego...@redhat.com> > --- > src/gallium/drivers/nouveau/nv30/nv30_screen.c | 3 ++- > 1 file changed, 2 insertions(+), 1 deletion(-) > > diff --git a/src/gallium/drivers/nouveau/nv30/nv30_screen.c > b/src/gallium/drivers/nouveau/nv30/nv30_screen.c > index 69acc38..57262b8 100644 > --- a/src/gallium/drivers/nouveau/nv30/nv30_screen.c > +++ b/src/gallium/drivers/nouveau/nv30/nv30_screen.c > @@ -321,7 +321,8 @@ nv30_screen_is_format_supported(struct pipe_screen > *pscreen, > { > struct nv30_screen *screen = nv30_screen(pscreen); > > - if (screen->eng3d->oclass >= NV40_3D_CLASS) { > + /* MSAA visuals work somwhat on nv4x, but cause gpu lockups */ > + if (0 && screen->eng3d->oclass >= NV40_3D_CLASS) { > if (sample_count > 4) > return false; > } else { > -- > 2.4.3 > > _______________________________________________ > Nouveau mailing list > Nouveau@lists.freedesktop.org > http://lists.freedesktop.org/mailman/listinfo/nouveau _______________________________________________ Nouveau mailing list Nouveau@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/nouveau
