All Families

Display

Missing:

• 10/12-bit HDMI Output

Plumbing is there, only needs clock generation setup

• HDMI 4:2:0 Output

Plumbing is there, only needs mode setup and testing

• Cursor Plane support

More complex, would need refactor so support updating the cursor plane manually when in interlaced mode

• Second Video plane support
• HDR Transformations

Needs documentation

• Parallel Video output
• Picture post-processing

Needs documentation

Multimedia

Missing:

• MPEG-4/2/1/JPEG Decoder
• H264 Encoder

Meson6 / Meson8 / Meson8b

I'll let martin elaborate on that, but it seems the greatest missing bits are Display, Video Decoder & Encoder support.

GXBB

Audio

Broken: Multiple issues are reported with the Mainline AIU driver:
