In Direct3D 8 and 9, a pointer to a contiguous buffer is provided when a level is locked. This contiguous buffer is encompassing of all the mipmap levels including the level asked for, and all the levels to follow.
Some games, such as Phantasy Star Online: Blue Burst exploit this to populate all mipmap levels simultaneously.
There is a branch called lock-rect-all-mips which is experimenting with a fix.
