STATUS

Supported variants

  • samsung-espressowifi, which is almost identically similar to samsung-espresso3g, but with the exception that it has no modem.

Display

OMAPDRM works fine.

Display seems to be running at 30Hz due to the clock speed for 60Hz not working properly.

Brightness needs a correct PWM clock value until that is done it flickers at low brightness.

Touchscreen

Touchscreen is MMS136 and it works fine. Already in upstream.

Bluetooth

Bluetooth works. You can enable and manage it with bluez and bluetoothctl.

Battery

Fuel gauge works fine. The charger driver is WIP, if connected to usb during boot, then only it charges.

Camera

OMAP4 has different subsystem (Ducati) for camera which is non free. Probably will never work on mainline.

3D GPU Acceleration

3D acceleration works fine. SGX540 blobs also seem to be missing some EGL configs, so UIs like plasma-mobile do not work, gnome-software crashes etc. It crashes sometimes like when opening firefox. Video decoding does not work as it is done by Ducati subsystem.
