yes, this happens on SKL-S for some reason, probably should upstream a

Title:
Wily: firmware load for i915/skl_dmc_ver1.bin failed with error -2
Status in linux package in Ubuntu:
Triaged
Bug description:
On Skylake, the skl_dmc firmware is failing to load. From dmesg:
[ 0.728803] i915 0000:00:02.0: Direct firmware load for
i915/skl_dmc_ver1.bin failed with error -2
[ 0.728817] [drm:i915_firmware_load_error_print [i915]] *ERROR* failed to
load firmware i915/skl_dmc_ver1.bin (0)
This means the GPU can't enter its lowest available power states, plus
many display hotplugging scenarios (that only the skl_dmc firmware can
handle) are broken.
On a whim I tried some other firmware versions:
1) pointed the skl_dmc_ver1.bin symlink to skl_dmc_ver1_18.bin
(instead of skl_dmc_ver1_19.bin)
2) downloaded the latest (skl_dmc_ver1_21.bin) and pointed the
skl_dmc_ver1.bin symlink to it
But neither corrected the situation.
Thanks!
