Some Gen7/8 production parts may have the Display Pipe C fused off. In this case, the display hardware will prevent the enable bit in PIPE_CONF register (for Pipe C) from being set to 1. Fixed by adjusting pipe_count to reflect this. v2: Rename HSW_PIPE_C_DISABLE to IVB_PIPE_C_DISABLE as it already exists on ivybridge (Ville) v3: Remove unnecessary MMIO read, correct the description (Damien) v4: Be more specific in description (Patrick) Signed-off-by: Gabriel Feceoru <gabriel.feceoru@intel.com> Reviewed-by: Patrik Jakobsson <patrik.jakobsson@linux.intel.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: http://patchwork.freedesktop.org/patch/msgid/1453462125-21519-1-git-send-email-gabriel.feceoru@intel.com |
