+## Status
+
+### Working
+
+* Onchip IPs seem to work
+* Ethernet
+* GPU - on wayland (the `swaywm` included within sdcard image)
+  * Start `sway` will then load Mali firmware, to check GPU accelleration, run firefox with Wayland enable `MOZ_ENABLE_WAYLAND=1 firefox`
+    * `about:support` will show the status of GPU supporting
+  * Perf is quite good - video playback consumed ~30% CPU (1080p youtube video on 4K monitor), ~50% CPU (4K youtube video on 4K monitor) - fullscreen mode
+* USB-C OTG-mode
+* Other? - not fully check (not that intrrested in :D)
+* Audio
