Which kernel version are you testing? There were some fixes in 4.4/4.5 which may help for the kernel driver issues, but note that the Mesa radeonsi driver for >= 7xxx Radeons still needs a lot of work to be usable on big endian systems. -- Earthling Michel Dänzer | http://www.amd.com Libre software enthusiast | Mesa and X developer _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
