It is populated with movable pages until a CMA user needs a continuous block from it. Userspace (unless mlocked) and cache/buffers are all movable, so I don't think CMA would be underutilized in memory pressure scenarios. 16M was not enough for getting DRM display on dragonboard 410c.

Oh, yes I see. > 16M was not enough for getting DRM display on dragonboard 410c. I can > check what is the minimum needed. Given a single full-HD frame needs 8 MiB, I can see 16 MiB total would be too small. But then, multiply by 4 for 4K frames, and 64 MiB would also be constraining. (I don't know whether we currently support any hardware with 4K output.)
