Dear Arnd:
I need more than 512MB for CMA area in my system, such as 768MB, but lowmem only 760MB.
I try split kernel/user to 2G/2G, but some games run abnormal. :(

Dear Linaro term:
this is my system status:
kernel version: 3.10 kernel/user space split: 1G/3G system memory: 2GB lowmem/vmalloc: 760MB/240MB CMA reverse: 512MB
If CMA is placed in the lowmem area, it is working fine; when i move it to high zone, it working abnomaly:
I'm pretty sure CMA in highmem was never implemented. It's not trivial, and it's questionable whether this would be a good idea. Why do you want to do this?
