Hi jani, sorry to trouble you. ^-^ But we meet a new problem when we use drm-intel-nightly branch,it will report an error and many crash info in dmesg, please refer to attachment. What is i915/skl_dmc_ver4.bin and where to get it? And Does it will cause any problem if skl_dmc_ver4.bin is not loaded? what is the cut info?
One bug per report please, file new ones for new bugs.
You need the firmware. You can get it from https://01.org/linuxgraphics/downloads. Hopefully it will be included in linux-firmware sometime soon.
There's been some back and forth between the naming, see e.g. http://mid.gmane.org/1433375419-13266-1-git-send-email-rodrigo.vivi@intel.co..., I'm not sure which name is currently used in the download page.
