For consistency with the new way of doing things, let's read out the pipe select bits even when the port is disable, even though we don't need that behaviour for asserts in this case. v2: Order the defines shift,mask,value (Jani) Reviewed-by: Jani Nikula Signed-off-by: Ville Syrjälä Link: https://patchwork.freedesktop.org/patch/msgid/20180514172423.9302-5-ville.syrjala@linux.intel.com --- diff --git a/drivers/gpu/drm/i915/i915_reg.h b/drivers/gpu/drm/i915/i915_reg.h index dae213d..196a0eb 100644 --- a/drivers/gpu/drm/i915/i915_reg.h +++ b/drivers/gpu/drm/i915/i915_reg.h @@ -4357,7 +4357,9 @@ enum { #define _DVOC 0x61160 #define DVOC _MMIO(_DVOC) #define DVO_ENABLE (1 << 31) -#define DVO_PIPE_B_SELECT (1 << 30) +#define DVO_PIPE_SEL_SHIFT 30 +#define DVO_PIPE_SEL_MASK (1 << 30) +#define DVO_PIPE_SEL(pipe) ((pipe) << 30) #define DVO_PIPE_STALL_UNUSED (0 << 28) #define DVO_PIPE_STALL (1 << 28) #define DVO_PIPE_STALL_TV (2 << 28) diff --git a/drivers/gpu/drm/i915/intel_dvo.c b/drivers/gpu/drm/i915/intel_dvo.c index eb0c559b2..a86f039 100644 --- a/drivers/gpu/drm/i915/intel_dvo.c +++ b/drivers/gpu/drm/i915/intel_dvo.c @@ -137,19 +137,15 @@ static bool intel_dvo_connector_get_hw_state(struct intel_connector *connector) static bool intel_dvo_get_hw_state(struct intel_encoder *encoder, enum pipe *pipe) { - struct drm_device *dev = encoder->base.dev; - struct drm_i915_private *dev_priv = to_i915(dev); + struct drm_i915_private *dev_priv = to_i915(encoder->base.dev); struct intel_dvo *intel_dvo = enc_to_dvo(encoder); u32 tmp; tmp = I915_READ(intel_dvo->dev.dvo_reg); - if (!(tmp & DVO_ENABLE)) - return false; - - *pipe = PORT_TO_PIPE(tmp); + *pipe = (tmp & DVO_PIPE_SEL_MASK) >> DVO_PIPE_SEL_SHIFT; - return true; + return tmp & DVO_ENABLE; } static void intel_dvo_get_config(struct intel_encoder *encoder, @@ -276,8 +272,7 @@ static void intel_dvo_pre_enable(struct intel_encoder *encoder, dvo_val |= DVO_DATA_ORDER_FP | DVO_BORDER_ENABLE | DVO_BLANK_ACTIVE_HIGH; - if (pipe == 1) - dvo_val |= DVO_PIPE_B_SELECT; + dvo_val |= DVO_PIPE_SEL(pipe); dvo_val |= DVO_PIPE_STALL; if (adjusted_mode->flags & DRM_MODE_FLAG_PHSYNC) dvo_val |= DVO_HSYNC_ACTIVE_HIGH;
