Is that an invariant today? num_entries <= AMDGPU_GPU_PAGES_IN_CPU_PAGE skips the scan and is used as it is, so on a 64K page kernel a 4K mapping maps a single GPU page and pages_addr is not consumed in whole CPU pages there either. So what should the code do for a mapping whose size is not a multiple of AMDGPU_GPU_PAGES_IN_CPU_PAGE? Could you sketch what you have in mind? Thanks, Junrui Luo
