Until Pie, the ConfigStore HAL was supposed to configure SurfaceFlinger. Google, in their infinite wisdom, got bored of this approach and decided that sysprops (which ConfigStore was supposed to supplant, because of their _obvious drawbacks) were once again all the rage. The ConfigStore HAL is being deprecated and will apparently be removed in R. Translate the uppercase makevars that surfaceflinger.mk used to supply as cflags to configstore internals to sysprops. force_hwc_copy_for_virtual_displays = TARGET_FORCE_HWC_FOR_VIRTUAL_DISPLAYS max_frame_buffer_acquired_buffers = NUM_FRAMEBUFFER_SURFACE_BUFFERS Note: The uppercase vars must be kept because hardware/qcom/display still relies on them at build time. Further adjustments follow in the platform repos. `max_frame_buffer_acquired_buffers` will be overriden there for most devices.
