I don't mind adding a dma_resv_prune for locked case, but I don't think unlocked would have benefits.
Furthermore, I'm trying to remove the unlocked versions from i915. Could this be a prereq patch instead?
https://patchwork.freedesktop.org/patch/460722/?series=96115&rev=1
Yeah, that works for me as well.
I was on the edge of dropping that from TTM as well since this is really
just abusing the interface to save a few bytes of memory.
Feel free to add an Acked-by: Christian König <christian.koenig@xxxxxxx>
to the i915 patch if it helps to get that committed.
Regards,
Christian.
