> Have you specified this in your kernel, or in your initramfs? OK, I've downloaded kbl_dmc_ver1_04.bin now, but I'm having problems implementing it. First I saved it to /lib/firmware, entered the firmware name in "make menuconfig" (Build named firmware blobs into the kernel) and recompiled; same error message about no such file. Then I created subdirectory /lib/firmware/i915 and moved the bin there. I changed the entry in "make menuconfig" to "i915/kbl_dmc_ver1_04.bin" and recompiled. It finds the file now, but still errors out. dmesg says ========================================================================= [ 0.221960] Loading firmware: i915/kbl_dmc_ver1_04.bin [ 0.221962] i915 0000:00:02.0: [drm] *ERROR* DMC firmware has wrong CSS header length (1097158924 bytes) [ 0.221964] i915 0000:00:02.0: [drm] Failed to load DMC firmware i915/kbl_dmc_ver1_04.bin.
