I know of two kernel configuration options for Cirrus video cards:
CONFIG_DRM_CIRRUS_QEMU: Cirrus driver for QEMU emulated device
CONFIG_FB_CIRRUS: Cirrus Logic support
CONFIG_DRM_CIRRUS_QEMU is enabled as a module in all of our
configurations except for 5.2-arm-veyron.conf. CONFIG_FB_CIRRUS is
enabled as a module in all of our x86_64 and i686 configurations.
Is there something else I've overlooked?
Thanks,
Mark
