Sounds great! Sorry for a n00bie question. Once support for drm-kmod lands in the 11.2 kernel, will support for newer linuxkpi KMS APIs (i.e. 4.15) also require kernel changes or they will be supported through ports? I don't quite know how the support for linuxkpi drivers is split between the kernel and userland. Thanks GrzegorzJ
