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?


for example:
[    5.076518] i915 0000:00:02.0: Direct firmware load for
i915/skl_dmc_ver4.bin failed with error -2
[    5.076562] [drm:i915_firmware_load_error_print [i915]] *ERROR* failed to
load firmware i915/skl_dmc_ver4.bin (0)
