The dpll actually runs at the port clock so we don't need to multiply it again with the pixel multiplier to get the adjusted_mode.clock. This is in contrast to the ironlake pixel clock readout code which uses the fdi dotclock: That one does _not_ run with multiplied pixels. This issue goes back to the original clock readout code added in commit f1f644dc66cbaf5a4c7dcde683361536b41885b9 Author: Jesse Barnes <jbarnes@virtuousgeek.org> Date: Thu Jun 27 00:39:25 2013 +0300 drm/i915: get mode clock when reading the pipe config v9 Cc: Jesse Barnes <jbarnes@virtuousgeek.org> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> --- drivers/gpu/drm/i915/intel_display.c | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-)
