There are a few sections in the driver which are not compatible with

Disable the i915 driver on a PREEMPT_RT enabled kernel. This way
PREEMPT_RT itself can be enabled without needing to address the i915
issues first. The RT related patches are still in RT queue and will be

A gentle ping ;)
Could you paste a link to the queue of i915 patches pending for a quick
overview of how much work there is and in what areas?
Also, I assume due absence of ARCH_SUPPORTS_RT being defined by any
arch, that something more is not yet ready?
