--- Comment #9 from Hans de Goede <jwrdegoede at fedoraproject.org> ---
Hi All,

So I recently bought a (second-hand) Bay Trail tablet which has its LCD mounted
upside-down. As such I've ported Ville Syrjala's patches to deal with this to
current mainline and I'm going to send them upstream for merging.

These patches fix the kernel-console as well as the boot-splash (at leats
plymouth does not reset the rotation) being upside down as soon as a native kms
driver such as the i915 driver is loaded.

This fixes the orientation of the displayed image from boot till the Xserver or
a Wayland compositor takes over.

I've a patch for iio-sensor-proxy which fixes the rotation under Xorg / Wayland
when using a desktop environment which honors iio-sensor-proxy's rotation
detection:
https://github.com/hadess/iio-sensor-proxy/pull/162

The 2 patches I'm posting upstream for this can be found here:

Regards,

Hans
