Who will release CMA memory and how? Who will monitor that? What are > the "some memory tight scenarios"? What's the overall design goal? I may not be describing exactly what i mean,My intention is to find out how much of the reserved CMA space is actually used and which is unused, For those that are not used, I understand that they can be released by cma_release(). Of course, This is just a little personal thought that I think is helpful for saving memory. > -- Best Regards! Xin Hao
