Not that all the memory is not necessarily resident: heap BO size is counted even though only part of the memory reserved for those BOs might be allocated. drm-memory-resident: resident memory size. For normal BOs it's the same as drm-memory-all, but for heap BOs, only the memory actually allocated is counted. drm-memory-purgeable: amount of memory that can be reclaimed by the system (madvise(DONT_NEED)). drm-memory-shared: amount of memory shared through dma-buf.
