From 407b0fcd8becc2c948bbe3337db0cf2a45f19949 Mon Sep 17 00:00:00 2001 From: Maxime Ripard Date: Thu, 21 Apr 2022 11:13:00 +0200 Subject: [PATCH] drm/vc4: kms: Register a different drm_mode_config_funcs on BCM2711 On the BCM2711, our current definition of drm_mode_config_funcs uses the custom vc4_fb_create(). However, that function relies on the buffer allocation path that was relying on the GPU, and is no longer relevant. Let's create another drm_mode_config_funcs structure that we will register on the BCM2711.
