Huge Page support for sizes > 2048Kb on Petalinux 2018.2, ZCU102, A53
Does anyone know how to enable a huge page size that's greater than 2Mb (say, 512Mb or 1Gb) on the A53 using Petalinux v2018.2? I've tried setting it using bootargs (e.g., "hugepagesz=1G, default_hugepagesz=1G") and I can see that my boot arguments are in the line passed to the kernel at boot-up, but "cat /proc/meminfo" always reports back a huge page size of 2048Kb.
What's the secret to getting larger huge pages? :)
