How is GK20A different from a nvc0+ card that lacks PDISPLAY (like all the 3D Controller ones, and I guess even some that come up as VGA controller in PCI but don't have any outputs in their VBIOS)? i.e. what's wrong with just doing the same thing that GK1xx does? Note that there are sw methods that don't deal with display as well. -ilia > > Signed-off-by: Alexandre Courbot <acour...@nvidia.com> > --- > drivers/gpu/drm/nouveau/nouveau_drm.c | 5 +++++ > 1 file changed, 5 insertions(+) > > diff --git a/drivers/gpu/drm/nouveau/nouveau_drm.c > b/drivers/gpu/drm/nouveau/nouveau_drm.c > index ddd83756b9a2..5b46148ffd32 100644 > --- a/drivers/gpu/drm/nouveau/nouveau_drm.c > +++ b/drivers/gpu/drm/nouveau/nouveau_drm.c > @@ -208,6 +208,10 @@ nouveau_accel_init(struct nouveau_drm *drm) > return; > } > > + /* Need to figure out how to handle sw for gk20a */ > + if (device->chipset == 0xea) > + goto skip_sw_init; > + > ret = nouveau_object_new(nv_object(drm), NVDRM_CHAN, NVDRM_NVSW, > nouveau_abi16_swclass(drm), NULL, 0, > &object); > if (ret == 0) { > @@ -234,6 +238,7 @@ nouveau_accel_init(struct nouveau_drm *drm) > return; > } > > +skip_sw_init: > if (device->card_type < NV_C0) { > ret = nouveau_gpuobj_new(drm->device, NULL, 32, 0, 0, > &drm->notify); > -- > 1.9.2 > > _______________________________________________ > Nouveau mailing list > nouv...@lists.freedesktop.org > http://lists.freedesktop.org/mailman/listinfo/nouveau -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
