| |
Hi all
Working on a small device with 128MB of memory and using imx_v6_v7 defconfig I found that CMA_SIZE_MBYTES, CMA_SIZE_PERCENTAGE are not respected. The calculation done does not allow the requested size. I think that this should be somehow documented and described but I did not find the documentation. Does it work this way?
With CMA_SIZE of 8MB I need to have FORCE_MAX_ZONEORDER=12 if I have the default FORCE_MAX_ZONEORDER=14 the min size is 32Mb
Michael
