So in this version you don't change size2's type, but you still change size1's one :)? Other than that, looks good to me. > { > - uint32_t end1 = addr + size1; > - uint32_t end2 = start + size2; > + uint64_t end1 = addr + size1; > + uint64_t end2 = start + size2; > > if (within(addr, start, end2) && > end1 > addr && within(end1, start, end2)) { > return; > } > > - hw_error("EDU: DMA range 0x%.8x-0x%.8x out of bounds (0x%.8x-0x%.8x)!", > + hw_error("EDU: DMA range 0x%016"PRIx64"-0x%016"PRIx64 > + " out of bounds (0x%016"PRIx64"-0x%016"PRIx64")!", > addr, end1 - 1, start, end2 - 1); > } -- js suse labs
