2016-12-15 22:07:08 Philipp Kern 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!

This is because it is a symlink to a versioned blob and the initramfs-tools hook does not dereference symlinks. As the driver is actually loaded from the initramfs, the firmware is missing for the lifetime of the boot, which means that the GPU cannot enter its lowest available power states plus some hotplugging scenarios are broken. This all manifests itself as such in 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) [ Test Case ] After the fix has been applied and the initrd regenerates, the firmware should load successfully after a reboot. [ Regression Potential ] Unlikely, as the fix is part of Ubuntu since Wily.
