Display refresh

There is a bug whereby the screen is not automatically refreshed. To work around this, run the following command as root on the device:

# while [ ! ]; do cat /sys/class/graphics/fb0/modes > /sys/class/graphics/fb0/mode; done

Mainlining

Julian Goldsmith is currently working on mainlining the OnePlus One, based on flacks's initial DTS. Right now, he's using a fork of linux-postmarketos, and is trying to get hardware-accelerated graphics up and running.

Graphics

The Adreno 330 GPU is supported by Freedreno. The firmware is required, and is available in the adreno-firmware package.

Julian Goldsmith currently has partially-working graphics support on mainline. XFCE4 displays properly, but other environments haven't been tested yet. There is an issue where the screen doesn't properly update, which requires a workaround to disable the tearcheck pin.

Actual 3D applications, such as glxgears, run very poorly at the moment. This may be due to the tearcheck workaround.

Cell usage

oFono support shouldn't take too much to get up and running. Adding the remoteproc node, using qmictl (possibly more utilities), and using a patched oFono should get basic support up and running.

Additional info

Entering fastboot mode

From a power off state, hold the volume up and power buttons until the device vibrates. The display should then light up and say "Fastboot Mode".
