Hi Christian, Just wanted to confirm where you stand on this patch, since I think you reconsidered your initial position after first looking at 9/11 from this series. I do not know the amdgpu code well, but I think the changes should be fine - in struct amdgpu_bo_va_mapping, the "end" field will hold what was previously stored in the "last" field, plus one. The expectation is that overflows should not be an issue there, as "end" is explicitly declared as an uint64, and as the code was previously computing "last + 1" in many places. Does that seem workable to you ? Thanks, -- Michel "Walken" Lespinasse A program is never fully debugged until the last user dies.
