From d1f5ac4f1a999b010e043072bf5d26c80d382b33 Mon Sep 17 00:00:00 2001 From: Phil Elwell Date: Fri, 10 Mar 2023 15:07:10 +0000 Subject: [PATCH] overlays: vc4-kms/fkms-v3d: Raise CMA to 512MB On Pi 4, raise the requested CMA size to 512MB by default, on the understanding that the firmware will cap that to 256MB if it's a 32-bit kernel with less than 2GB of RAM.
