Indications are that no GF116's actually have a copy engine there, but actually have the decompression engine. This engine can be made to do copies, but that should be done separately. Unclear why this didn't turn up on all GF116's, but perhaps the non-mobile ones came with enough VRAM to not trigger ttm migrations in test scenarios.

I don't have the card at hand right now so don't know how much VRAM it had, though. Thanks for getting this figured out :)> Fixes: https://bugs.freedesktop.org/show_bug.cgi?id=85465 > Fixes: https://bugs.freedesktop.org/show_bug.cgi?id=59168 > Cc: stable at vger.kernel.org > Signed-off-by: Ilia Mirkin <imirkin at alum.mit.edu> > --- > nvkm/engine/device/nvc0.c | 1 - > 1 file changed, 1 deletion(-) > > diff --git a/nvkm/engine/device/nvc0.c b/nvkm/engine/device/nvc0.c > index cd05677..72a40f9 100644 > --- a/nvkm/engine/device/nvc0.c > +++ b/nvkm/engine/device/nvc0.c > @@ -218,7 +218,6 @@ nvc0_identify(struct nouveau_device *device) > device->oclass[NVDEV_ENGINE_BSP ] = &nvc0_bsp_oclass; > device->oclass[NVDEV_ENGINE_PPP ] = &nvc0_ppp_oclass; > device->oclass[NVDEV_ENGINE_COPY0 ] = &nvc0_copy0_oclass; > - device->oclass[NVDEV_ENGINE_COPY1 ] = &nvc0_copy1_oclass; > device->oclass[NVDEV_ENGINE_DISP ] = nva3_disp_oclass; > device->oclass[NVDEV_ENGINE_PERFMON] = &nvc0_perfmon_oclass; > break; >-- Anssi Hannula
