Building the i915 driver into the Linux kernel, that means not as a module, *without* an initrd image, the message below is shown. [ 0.427657] i915 0000:00:02.0: Direct firmware load for i915/skl_dmc_ver1_27.bin failed with error -2 [ 0.428121] i915 0000:00:02.0: Failed to load DMC firmware i915/skl_dmc_ver1_27.bin.

The best solution would be to not require firmware at all as in earlier hardware generations. As a workaround it’d be great if the driver supported to load firmware after the initialization phase.
Sorry, I don't think we want to take on supporting this configuration.
