Commit a55409066 ("drm/nv50-: map TTM_PL_SYSTEM through a BAR for CPU access") made it possible to work with tiled memory. However mem->mm_node is not a nouveau_mem for AGP-using pre-NV50 cards, but a drm_mm_node, as created by the ttm_bo_manager_func. As such, extend the untiled check to explicitly include all pre-nv50 cards. Reported-by: Ronald <ronald645 at gmail.com>

nv50_bo_move_m2mf might copy to tiled gart, in which case linear copy is not appropriate. --- drivers/gpu/drm/nouveau/nouveau_bo.c | 42 ++++++++++++++++++++---------------- 1 file changed, 24 insertions(+), 18 deletions(-) diff --git a/drivers/gpu/drm/nouveau/nouveau_bo.c b/drivers/gpu/drm/nouveau/nouveau_bo.c index 88f0c45..0daf3f0 100644 --- a/drivers/gpu/drm/nouveau/nouveau_bo.c +++

move_notify is called by ttm after the the object is idle and about to be destroyed. Clean up the vm list properly in that case. This is not a problem right now, since the list should already be empty, but if it wasn't empty, vm_put was not called which leads to random corruption later. With this fix, nouveau_gem_object_close can be safely changed to a noop, forcing the vm bindings to be

Second version of this patchset addressing Ben's comments and fixing a few extra things. This patchset proposes to introduce a "staging" module option to dynamically enable features (mostly ioctls) that are merged but may be refined before they are declared "stable". The second patch illustrates the use of this staging option with the SET_TILING ioctl, which can be used to

Drop the dummy ttm backend implementation, add a real one for TTM_PL_FLAG_TT objects. The bin/unbind callbacks will call virtio_gpu_object_{attach,detach}, to update the object state on the host side, instead of invoking those calls from the move_notify() callback. With that in place the move and move_notify callbacks are not needed any more, so drop them. Signed-off-by: Gerd Hoffmann
