From d157fbd5b4b59aa863cbb82d4ad08596996d3ab0 Mon Sep 17 00:00:00 2001 From: Matt Macy Date: Wed, 22 Aug 2018 01:50:12 +0000 Subject: [PATCH] Remove legacy drm and drm2 from tree As discussed on the MLs drm2 conflicts with the ports' version and there is no upstream for most if not all of drm. Both have been merged in to a single port. Users on powerpc, 32-bit hardware, or with GPUs predating Radeon and i915 will need to install the graphics/drm-legacy-kmod. All other users should be able to use one of the LinuxKPI-based ports: graphics/drm-stable-kmod, graphics/drm-next-kmod, graphics/drm-devel-kmod.
