Hi,
I would request beaglebones users (either Black or white) to do some tests
about a possible
cma=64M to be set on kernel cmdline:
# sed -i 's/^ABC_BASEARGS="\(.*\)"/ABC_BASEARGS="\1
cma=64M\"/'
/etc/sysconfig/arm-boot-config
# a-b-c
# reboot
By default cma is set to 16 and is not enought for some cases: (see
rhbz#1127000)
The goal is to see how it behaves on bb
Journalctl -b currently shows:
cma: CMA: reserved 16 MiB at 3e800000
At should show 64 MiB on the next boot.
What would be nice to test is for possible regression on memory usage or
else.
I let the cma conservative camp to provide any appropriate tests to support
theirs arguments:

I don't see why the reverse use case can't be done. It's not all about
just the devices you use.
I also don't see why you've moved this discussion from the BZ where it
was being discussed to the list all of a sudden
