18:28 TimurTabi: Is there some kind of restriction on the virtual address returned by dma_alloc_coherent w.r.t. user space access?
18:29 TimurTabi: That is, you can't call copy_to_user() with that pointer?
18:35 karolherbst: TimurTabi: might be better to ask such general questions in #dri-devel, as there are more people around dealing with those kind of things
18:45 airlied: TimurTabi: you can't call copy_to_user with that pointer as destination I would think
18:45 TimurTabi: As a source, I mean.
18:45 TimurTabi: Anyway, I got it towork, so there must be something wrong with my test code instead.
18:45 airlied: a source should be fine
