# The default BAR address space available on the CM4 is too small to allow
# devices like GPUs to initialize correctly. To avoid 'failed to assign memory'
# errors on boot, we need to increase the range of the PCIe bus in the Raspberry
# Pi's Device Tree (a .dtb file specific to each Pi model).
#
# You should probably read up on Device Trees if you don't know what they are:
# https://www.raspberrypi.org/documentation/configuration/device-tree.md

# Attempt to set up the Nvidia GeForce GT 710 on a Pi CM4.
#
# I have tried both armv7l and aarch64 versions of the proprietary driver, in
# addition to the nouveau open source driver (which needs to be compiled into
# a custom Raspberry Pi kernel).
#
# tl;dr - None of the drivers worked :P
