From: Daniel Vetter Date: Fri, 18 Oct 2013 14:37:07 +0000 (+0200) Subject: drm/i915: bikeshed the pipe CRC irq functions a bit X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=277de95e4e5ec39edab779efe388894d5cc06582;p=linux-beck.git drm/i915: bikeshed the pipe CRC irq functions a bit - Give them an _irq_handler postfix, like all the other irq stuff. - Shuffle the DEBUG_FS=n dummy functions around a bit. This is prep work to extract all the crc debug stuff into intel_display_testing.c Reviewed-by: Ville Syrjälä Signed-off-by: Daniel Vetter --- diff --git a/drivers/gpu/drm/i915/i915_irq.c b/drivers/gpu/drm/i915/i915_irq.c index 5c3baa0ec049..8f7baad72316 100644 --- a/drivers/gpu/drm/i915/i915_irq.c +++ b/drivers/gpu/drm/i915/i915_irq.c @@ -1190,10 +1190,10 @@ static void dp_aux_irq_handler(struct drm_device *dev) } #if defined(CONFIG_DEBUG_FS) -static void display_pipe_crc_update(struct drm_device *dev, enum pipe pipe, - uint32_t crc0, uint32_t crc1, - uint32_t crc2, uint32_t crc3, - uint32_t crc4) +static void display_pipe_crc_irq_handler(struct drm_device *dev, enum pipe pipe, + uint32_t crc0, uint32_t crc1, + uint32_t crc2, uint32_t crc3, + uint32_t crc4) { struct drm_i915_private *dev_priv = dev->dev_private; struct intel_pipe_crc *pipe_crc = &dev_priv->pipe_crc[pipe]; @@ -1227,29 +1227,37 @@ static void display_pipe_crc_update(struct drm_device *dev, enum pipe pipe, wake_up_interruptible(&pipe_crc->wq); } +#else +static inline void +display_pipe_crc_irq_handler(struct drm_device *dev, enum pipe pipe, + uint32_t crc0, uint32_t crc1, + uint32_t crc2, uint32_t crc3, + uint32_t crc4) {} +#endif + -static void hsw_pipe_crc_update(struct drm_device *dev, enum pipe pipe) +static void hsw_pipe_crc_irq_handler(struct drm_device *dev, enum pipe pipe) { struct drm_i915_private *dev_priv = dev->dev_private; - display_pipe_crc_update(dev, pipe, - I915_READ(PIPE_CRC_RES_1_IVB(pipe)), - 0, 0, 0, 0); + display_pipe_crc_irq_handler(dev, pipe, + I915_READ(PIPE_CRC_RES_1_IVB(pipe)), + 0, 0, 0, 0); } -static void ivb_pipe_crc_update(struct drm_device *dev, enum pipe pipe) +static void ivb_pipe_crc_irq_handler(struct drm_device *dev, enum pipe pipe) { struct drm_i915_private *dev_priv = dev->dev_private; - display_pipe_crc_update(dev, pipe, - I915_READ(PIPE_CRC_RES_1_IVB(pipe)), - I915_READ(PIPE_CRC_RES_2_IVB(pipe)), - I915_READ(PIPE_CRC_RES_3_IVB(pipe)), - I915_READ(PIPE_CRC_RES_4_IVB(pipe)), - I915_READ(PIPE_CRC_RES_5_IVB(pipe))); + display_pipe_crc_irq_handler(dev, pipe, + I915_READ(PIPE_CRC_RES_1_IVB(pipe)), + I915_READ(PIPE_CRC_RES_2_IVB(pipe)), + I915_READ(PIPE_CRC_RES_3_IVB(pipe)), + I915_READ(PIPE_CRC_RES_4_IVB(pipe)), + I915_READ(PIPE_CRC_RES_5_IVB(pipe))); } -static void i9xx_pipe_crc_update(struct drm_device *dev, enum pipe pipe) +static void i9xx_pipe_crc_irq_handler(struct drm_device *dev, enum pipe pipe) { struct drm_i915_private *dev_priv = dev->dev_private; uint32_t res1, res2; @@ -1264,17 +1272,12 @@ static void i9xx_pipe_crc_update(struct drm_device *dev, enum pipe pipe) else res2 = 0; - display_pipe_crc_update(dev, pipe, - I915_READ(PIPE_CRC_RES_RED(pipe)), - I915_READ(PIPE_CRC_RES_GREEN(pipe)), - I915_READ(PIPE_CRC_RES_BLUE(pipe)), - res1, res2); + display_pipe_crc_irq_handler(dev, pipe, + I915_READ(PIPE_CRC_RES_RED(pipe)), + I915_READ(PIPE_CRC_RES_GREEN(pipe)), + I915_READ(PIPE_CRC_RES_BLUE(pipe)), + res1, res2); } -#else -static inline void hsw_pipe_crc_update(struct drm_device *dev, int pipe) {} -static inline void ivb_pipe_crc_update(struct drm_device *dev, int pipe) {} -static inline void i9xx_pipe_crc_update(struct drm_device *dev, int pipe) {} -#endif /* The RPS events need forcewake, so we add them to a work queue and mask their * IMR bits until the work is done.
