Dear All,
Now I have one DB845c running with android 11.
For the display setting in platform/device/linaro/dragonboard/device-common.mk:
Display
PRODUCT_PACKAGES +=
android.hardware.drm@1.0-impl
android.hardware.drm@1.0-service
android.hardware.graphics.allocator@2.0-impl
android.hardware.graphics.allocator@2.0-service
android.hardware.graphics.composer@2.2-impl
android.hardware.graphics.composer@2.2-service
android.hardware.graphics.mapper@2.0-impl-2.1
gralloc.gbm
hwcomposer.drm
libGLES_mesa
PRODUCT_PROPERTY_OVERRIDES +=
ro.hardware.gralloc=gbm
ro.hardware.hwcomposer=drm \
The rendering uses HW composer and GPU.
Questions:
-
How can I use the pure SW rendering without HWC and GPU ?
(How can I modify the setting in device/linaro/dragonboard/device-common.mk and
device/linaro/dragonboard/BoardConfigCommon.mk ?) -
Can I still use gralloc.gbm or use gralloc.default ?
Thank you so much.
