- * The transfer should map the resource storage directly and the GPU should
- * be able to see what the CPU has written. Such a storage may stay mapped
- * while issuing draw commands which use it. The only allowed usage is
- * non-overlapping writes which are suballocated out of a big buffer.
- * The minimum allowed alignment of suballocations is 256 bytes (this is
- * a subject to change).
- * The flag is intended to be used to avoid mapping and unmapping
- * resources repeatedly when doing uploads and draws intermixed.
- *
- * The driver may return NULL if that isn't possible, and the state
- * tracker needs to cope with that and use an alternative path
- * without this flag.
