== Device Information / Hardware ==

The Broadcom 97425 is a powerful dual core MIPS set-top-box reference design. The
hardware is capable of running QtQuick2/SceneGraph. Broadcom provides an optimized
version of DirectFB for 2D graphics, input and image decoding. The multimedia architecture
is based on GStreamer. Broadcom provides pipeline elements to access their hardware.

== Software provided by Broadcom ==

Broadcom provides customers with the AppLibs and RefSW. The last tested version is '''20111222'''
for the RefSW '''20111222'''. The rockford 3D library needs to link to DirectFB to avoid
missing symbols when loading the DirectFB/QPA plugin. The patch was provided to Broadcom and
should be included in future versions.

=== Building Qt ===

<code>
# This assumes that DirectFB was built in multi application mode
$ export PKG_CONFIG_PATH=BCtree/AppLibs/opensource/directfb/bin/DirectFB-1.4.15_multi_release_build.97425B1/usr/local/lib/pkgconfig/
$ mkdir build-qtbase
$ cd build-qtbase
$ ../build-qtbase/configure -release  -device linux-mipsel-broadcom-97425-g++  -no-xcb -no-eglfs  -device-option B_REFSW_DEBUG=n  -device-option BRCM_ROCKFORD_PATH=BCtree/rockford  -device-option BRCM_APPLIBS_PATH=BCtree/AppLibs  -opengl es2  -no-mips_dsp -no-mips_dspr2  -directfb  -force-pkg-config
$ make install
</code>

=== Running Qt ===
<code>
$ export QT_QPA_PLATFORM=directfbegl
$ ./wiggly </code>
