So here we use the right thing at the right place. Signed-off-by: Paulo Zanoni [danvet: apply the patch by hand due to the reorder patch sequence. We also can't kill all uses of pipe where we should, since the fdi link train code isn't fixed up yet on this baselin.] Signed-off-by: Daniel Vetter --- diff --git a/drivers/gpu/drm/i915/intel_display.c b/drivers/gpu/drm/i915/intel_display.c index 58614f81c096..5582d5dc2d94 100644 --- a/drivers/gpu/drm/i915/intel_display.c +++ b/drivers/gpu/drm/i915/intel_display.c @@ -3170,8 +3170,9 @@ static void lpt_pch_enable(struct drm_crtc *crtc) struct drm_i915_private *dev_priv = dev->dev_private; struct intel_crtc *intel_crtc = to_intel_crtc(crtc); int pipe = intel_crtc->pipe; + enum transcoder cpu_transcoder = intel_crtc->cpu_transcoder; - assert_transcoder_disabled(dev_priv, pipe); + assert_transcoder_disabled(dev_priv, TRANSCODER_A); /* Write the TU size bits before fdi link training, so that error * detection works. */ @@ -3184,16 +3185,16 @@ static void lpt_pch_enable(struct drm_crtc *crtc) lpt_program_iclkip(crtc); /* Set transcoder timing. */ - I915_WRITE(TRANS_HTOTAL(pipe), I915_READ(HTOTAL(pipe))); - I915_WRITE(TRANS_HBLANK(pipe), I915_READ(HBLANK(pipe))); - I915_WRITE(TRANS_HSYNC(pipe), I915_READ(HSYNC(pipe))); + I915_WRITE(_TRANS_HTOTAL_A, I915_READ(HTOTAL(cpu_transcoder))); + I915_WRITE(_TRANS_HBLANK_A, I915_READ(HBLANK(cpu_transcoder))); + I915_WRITE(_TRANS_HSYNC_A, I915_READ(HSYNC(cpu_transcoder))); - I915_WRITE(TRANS_VTOTAL(pipe), I915_READ(VTOTAL(pipe))); - I915_WRITE(TRANS_VBLANK(pipe), I915_READ(VBLANK(pipe))); - I915_WRITE(TRANS_VSYNC(pipe), I915_READ(VSYNC(pipe))); - I915_WRITE(TRANS_VSYNCSHIFT(pipe), I915_READ(VSYNCSHIFT(pipe))); + I915_WRITE(_TRANS_VTOTAL_A, I915_READ(VTOTAL(cpu_transcoder))); + I915_WRITE(_TRANS_VBLANK_A, I915_READ(VBLANK(cpu_transcoder))); + I915_WRITE(_TRANS_VSYNC_A, I915_READ(VSYNC(cpu_transcoder))); + I915_WRITE(_TRANS_VSYNCSHIFT_A, I915_READ(VSYNCSHIFT(cpu_transcoder))); - intel_enable_transcoder(dev_priv, pipe); + intel_enable_transcoder(dev_priv, intel_crtc->pipe); } static void intel_put_pch_pll(struct intel_crtc *intel_crtc)
