First of all thanks for your great work so far.
I have tried the driver on my notebook with Iris 550.
After patching libdrm with
and installing the experimental xf86-video-intel driver it is partially
What's not working is:
- multi-monitor support (only tried with hdmi), after loading the
i915kms driver the output is duplicated, but there is no way of
controlling the outputs independently (xfce also shows only one
- Xorg refuses to start unless I kldload i915kms manually before trying
to start Xorg
- there are some rendering issues (pink lines, weird transparency where
there should be no transparency), but I don't know if these are related
to i915, the experimental xf86-video-intel driver or the software
