# qmake configuration for the Raspberry Pi 3 (32-bit) using the
# *experimental* VC4 driver for Mesa and DRM.
#
# This should allow accelerated EGL and OpenGL with eglfs via
# KMS/DRM/GBM (instead of the Broadcom-specific backend), under X11
# with xcb, and also enables (Qt)Wayland via the standard wayland-egl
# path. See https://dri.freedesktop.org/wiki/VC4
#
# Note that this is not the same as the default, Broadcom proprietary
# driver. Some functionality and extensions may therefore be missing,
# in particular when it comes to accelerated multimedia (video,
# camera).
#
# At the time of writing Raspbian has to be switched explicitly to the
# experimental VC4 driver. To do this, run raspi-config and enable it
# in Advanced Options -> GL Driver.
#
# Example configure command below. We disable using the GNU gold
# linker as it apparently has issues with ARMv8. In the configure
# output check that "EGLFS GBM .......... yes" is present, otherwise
# eglfs will not be functional.
#
# ./configure -release -opengl es2 -device linux-rasp-pi3-vc4-g++ \
# -device-option CROSS_COMPILE=~/raspbian/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian-x64/bin/arm-linux-gnueabihf- \
