From: Ville Syrjälä Date: Mon, 23 Sep 2013 14:48:20 +0000 (+0300) Subject: drm/i915: Fix intel_crtc_mode_get() mode clock X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=773ae0346576a19b6a5e10adb0f63deca603ee00;p=linux-beck.git drm/i915: Fix intel_crtc_mode_get() mode clock i9xx_crtc_clock_get() no longer populates adjusted_mode.clock, so we must get the pixel clock from port_clock in intel_crtc_mode_get(). This bug caused Chris's 845g machine to lockup during boot, and it was introduced in: commit 18442d08786472c63a0a80c27f92b033dffc26de Author: Ville Syrjälä Date: Fri Sep 13 16:00:08 2013 +0300 drm/i915: Fix port_clock and adjusted_mode.clock readout all over Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=69713 Tested-by: Chris Wilson Signed-off-by: Ville Syrjälä Signed-off-by: Daniel Vetter --- diff --git a/drivers/gpu/drm/i915/intel_display.c b/drivers/gpu/drm/i915/intel_display.c index 5a9683761c8f..a3f21a508d0e 100644 --- a/drivers/gpu/drm/i915/intel_display.c +++ b/drivers/gpu/drm/i915/intel_display.c @@ -7543,7 +7543,7 @@ struct drm_display_mode *intel_crtc_mode_get(struct drm_device *dev, pipe_config.dpll_hw_state.fp1 = I915_READ(FP1(pipe)); i9xx_crtc_clock_get(intel_crtc, &pipe_config); - mode->clock = pipe_config.adjusted_mode.clock; + mode->clock = pipe_config.port_clock / pipe_config.pixel_multiplier; mode->hdisplay = (htot & 0xffff) + 1; mode->htotal = ((htot & 0xffff0000) >> 16) + 1; mode->hsync_start = (hsync & 0xffff) + 1;
