# This file contains only configs which are required to boot all configurations.

## gem5 x86

# CONFIG_INPUT_MOUSE is not set
# CONFIG_INPUT_MOUSEDEV_PSAUX is not set

## qemu aarch64

# For some reason not selected by the Buildroot kernel config by default as it was for arm,
# and pci modules fail to build. Not that we have PCI working on ARM anyways.
CONFIG_PCI=y

## gem5 aarch64

# Minimal options required to run gem5 aarch64 in addition to QEMU's aarch64 setup.
# Doing such a minimal boot made the gem5 boot 3x faster on the P51, which is awesome.
CONFIG_ATA_PIIX=y
CONFIG_PCI_HOST_GENERIC=y

## qemu aarch64 ext2

# Also requires gem5 aarch64 options.
# Not needed for initrd / initramfs.
