As I mentioned earlier – OS compatibility shim was removed from upstream sources so I had to create Linux KPI implementation layer which turned out not that awful task because I managed to reuse a lot of code from Max Khon’s DAHDI port. I had to implement (in somewhat hackish fashion) kthread API, re-implement semaphores support using condvar and mutex in order to get _interruptible part of API working properly and create dumb implementation of rather small subset of Linux list.h API.
With latest code I got pretty much all demos in hello_pi working except hello_jpeg(crashes system) and hello_encode(didn’t test). The most exciting bit for me was watching H.264 video playing on Raspberry Pi in hello_video demo. Network throughput still sucks so I had to copy file to tmpfs partition in order to get smooth playback though.
If you want to test VCHIQ – in addition to sources you’ll need latest firmware files. For demos you’ll also have to install freetype2 and manually hack Makefile.include in hello_pi. I’m planning to create ports/packages for both drivers and userland some time next week.
On the related note: Aleksandr Rybalko got XOrg working on Efika MX Smartbook so FreeBSD/Pi will get graphic interface soon
