Qt5 for FreeBSD/Pi

Wed, 14 Jan 2015 20:26:55 +0000

Build SD card image using crochet-freebsd with option VideoCore enabled. Mount either SD card itself of image to build host

mount /dev/mmcsd0s2a /pi

Checkout Qt5 sources and patch them

cd /src
git clone git://gitorious.org/qt/qt5.git qt5
cd qt5
git checkout 5.4.0
MODULES=qtbase,qtdeclarative,qtgraphicaleffects,qtimageformats,qtquick1,qtquickcontrols,qtscript,qtsvg,qtxmlpatterns
./init-repository --module-subset=$MODULES

fetch -q -o - http://people.freebsd.org/~gonzo/arm/rpi/qt5-freebsd-pi.diff | patch -p1

Configure, build and install Qt5 to SD card

./configure -platform unsupported/freebsd-clang -no-openssl -opengl es2 -device freebsd-rasp-pi-clang -device-option CROSS_COMPILE=/usr/armv6-freebsd/usr/bin/ -sysroot /pi/ -no-gcc-sysroot -opensource -confirm-license -optimized-qmake -release -prefix /usr/local/Qt5 -no-pch -nomake tests -nomake examples -plugin-sql-sqlite

gmake -j `sysctl -n hw.ncpu`
sudo gmake install

You need BSD-specific plugins to enable mouse and keyboard input in EGLFS mode

Audio on Raspberry Pi

Fri, 09 Jan 2015 23:25:08 +0000

With stable VCHIQ driver next obvious target was to add VCHIQ-based audio support. So let me introduce to you: vchiq_audio, first take. It’s part of vchiq-freebsd repo so if you use Crochet to build SD card image just enable option VideoCore in config file and module will be automatically included.

From shell run kldload vchiq_audio and you’re good to do. I believe that audio output is picked up automatically by VideoCore so if you have HDMI connected it’s probably going to be HDMI. I do not have device to confirm this. Adding knob to control audio output (auto, headphones, HDMI) is on my ToDo list.

RaspberryPi, FreeBSD and ioquake3

Update: support for keyboard/mouse has been added

After New Year I got back to hacking the VCHIQ stuff (thanks to adrian@ for prodding). Since last time I touched NetBSD folks got it merged to main tree, syncing with latest upstream code and fixing some stupid bugs in my codebase. So I partially merged things back, spent some time on fixing more bugs introduced by yours truly, merged userland bits from latest Broadcom’s bits (and fixing some bugs introduced by them). And as a result VCHIQ got stable enough to run ioquake3d on raspberry pi. Well, you can’t play it because there is no sound and no mouse support and keyboard support is severely crippled but you can navigate menus and watch demoes.
