drm-next reverted the changes to ttm_tt_create() to do the NULL check inside the function, but drm-misc-next adds new users of this approach. Re-apply the NULL check change inside the function to fix this. Signed-off-by: Christian K?nig <christian.koenig at amd.com> Reviewed-by: Dave Airlie <airlied at redhat.com> Link: https://pa...

Hi guys, I already tried this a few month ago, but since I don't have NVidia hardware its rather hard to test for me (need to get some ordered). Dave brought up the topic that we should probably try to move the handling into Nouveau once more, so I tried to fix the problem Ben reported and rebased on top of current drm-misc-next. Dave can you test this? At least in theory the approach

Several simple framebuffer drivers copy most of the TTM code from each other. The implementation is always the same; except for the name of some data structures. As recently discussed, this patch set provides generic memory-management code for simple framebuffers with dedicated video memory. It further converts the respective drivers to the generic code. The shared code is basically the same

...au_sgdma_create_ttm() always allocates a ttm_dma_tt structure, which is wrong but happens to suit us for now. Still, this part of the code could be rewritten much more cleanly if only we could access the nouveau_bo instance in these functions. I proposed some time ago to address this by making the ttm_tt_create hook take a pointer to a ttm_bo_object instead of a ttm_bo_device. This would still allow us to access the ttm_bo_device, while letting us retrieve the nouveau_bo and store it into whatever structure we embed our TTM into. For some reason David was not fond of the idea - I am taking another chance...
