From: Ville Syrjälä Date: Fri, 6 Sep 2013 20:28:59 +0000 (+0300) Subject: drm/i915: Make adjusted_mode.clock non-pixel multiplied X-Git-Tag: next-20130919~37^2~39 X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=3c52f4eb9335475b7336e2d9f42cd2d41b83fc97;p=karo-tx-linux.git drm/i915: Make adjusted_mode.clock non-pixel multiplied It would be easier if adjusted_mode.clock would be the pipe pixel clock, and it actually is, except for the cases where pixel_multiplier > 1. So let's change intel_sdvo to use port_clock as the multiplied clock, and then we can leave adjusted_mode.clock as pipe pixel clock. v2: Improve port_clock documentation Rebased on top of SDVO pixel_multiplier fixes Signed-off-by: Ville Syrjälä Reviewed-by: Jani Nikula Signed-off-by: Daniel Vetter --- diff --git a/drivers/gpu/drm/i915/intel_display.c b/drivers/gpu/drm/i915/intel_display.c index 42b5fa16ec8b..f1b3d33320d1 100644 --- a/drivers/gpu/drm/i915/intel_display.c +++ b/drivers/gpu/drm/i915/intel_display.c @@ -4061,7 +4061,6 @@ retry: link_bw = intel_fdi_link_freq(dev) * MHz(100)/KHz(1)/10; fdi_dotclock = adjusted_mode->clock; - fdi_dotclock /= pipe_config->pixel_multiplier; lane = ironlake_get_lanes_required(fdi_dotclock, link_bw, pipe_config->pipe_bpp); @@ -7370,8 +7369,7 @@ static void ironlake_crtc_clock_get(struct intel_crtc *crtc, clock = ((u64)link_m * (u64)link_freq); do_div(clock, link_n); - pipe_config->adjusted_mode.clock = clock * - pipe_config->pixel_multiplier; + pipe_config->adjusted_mode.clock = clock; } /** Returns the currently programmed mode of the given pipe. */ @@ -8316,7 +8314,8 @@ encoder_retry: /* Set default port clock if not overwritten by the encoder.
