From 02c07b76af5a7b97f4af1d211503b53444193dbb Mon Sep 17 00:00:00 2001 From: Lucas De Marchi Date: Fri, 16 Nov 2018 16:42:33 -0800 Subject: [PATCH] drm/i915: allow to load DMC firmware on next gen Before commit d8a5b7d79fb7 ("drm/i915/csr: keep max firmware size together with firmare name and version") it was possible to load the firmware for testing purposes via parameter. Let's use the size of the last known platform to recover that behavior.
