From: Paulo Zanoni Date: Fri, 12 Jul 2013 23:01:56 +0000 (-0300) Subject: drm/i915: kill ivybridge_irq_postinstall X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=8e76f8dc49f180b0e9d750426c99e37a7d6162ae;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git drm/i915: kill ivybridge_irq_postinstall It was very similar to ironlake_irq_postinstall, so IMHO merging both functions results in a code that is easier to maintain. With this change, all the irq handler vfuncs between ironlake and ivybridge are now unified. v2: Add "(" and ")" to make at least one vim user much happier (Chris) Signed-off-by: Paulo Zanoni Reviewed-by: Mika Kuoppala Signed-off-by: Daniel Vetter --- diff --git a/drivers/gpu/drm/i915/i915_irq.c b/drivers/gpu/drm/i915/i915_irq.c index 9d5ae21f39ba..1fffb4b10a05 100644 --- a/drivers/gpu/drm/i915/i915_irq.c +++ b/drivers/gpu/drm/i915/i915_irq.c @@ -2165,21 +2165,33 @@ static void gen5_gt_irq_postinstall(struct drm_device *dev) static int ironlake_irq_postinstall(struct drm_device *dev) { unsigned long irqflags; - drm_i915_private_t *dev_priv = (drm_i915_private_t *) dev->dev_private; - /* enable kind of interrupts always enabled */ - u32 display_mask = DE_MASTER_IRQ_CONTROL | DE_GSE | DE_PCH_EVENT | - DE_PLANEA_FLIP_DONE | DE_PLANEB_FLIP_DONE | - DE_AUX_CHANNEL_A | DE_PIPEB_FIFO_UNDERRUN | - DE_PIPEA_FIFO_UNDERRUN | DE_POISON; + u32 display_mask, extra_mask; + + if (INTEL_INFO(dev)->gen >= 7) { + display_mask = (DE_MASTER_IRQ_CONTROL | DE_GSE_IVB | + DE_PCH_EVENT_IVB | DE_PLANEC_FLIP_DONE_IVB | + DE_PLANEB_FLIP_DONE_IVB | + DE_PLANEA_FLIP_DONE_IVB | DE_AUX_CHANNEL_A_IVB | + DE_ERR_INT_IVB); + extra_mask = (DE_PIPEC_VBLANK_IVB | DE_PIPEB_VBLANK_IVB | + DE_PIPEA_VBLANK_IVB); + + I915_WRITE(GEN7_ERR_INT, I915_READ(GEN7_ERR_INT)); + } else { + display_mask = (DE_MASTER_IRQ_CONTROL | DE_GSE | DE_PCH_EVENT | + DE_PLANEA_FLIP_DONE | DE_PLANEB_FLIP_DONE | + DE_AUX_CHANNEL_A | DE_PIPEB_FIFO_UNDERRUN | + DE_PIPEA_FIFO_UNDERRUN | DE_POISON); + extra_mask = DE_PIPEA_VBLANK | DE_PIPEB_VBLANK | DE_PCU_EVENT; + } dev_priv->irq_mask = ~display_mask; /* should always can generate irq */ I915_WRITE(DEIIR, I915_READ(DEIIR)); I915_WRITE(DEIMR, dev_priv->irq_mask); - I915_WRITE(DEIER, display_mask | - DE_PIPEA_VBLANK | DE_PIPEB_VBLANK | DE_PCU_EVENT); + I915_WRITE(DEIER, display_mask | extra_mask); POSTING_READ(DEIER); gen5_gt_irq_postinstall(dev); @@ -2200,38 +2212,6 @@ static int ironlake_irq_postinstall(struct drm_device *dev) return 0; } -static int ivybridge_irq_postinstall(struct drm_device *dev) -{ - drm_i915_private_t *dev_priv = (drm_i915_private_t *) dev->dev_private; - /* enable kind of interrupts always enabled */ - u32 display_mask = - DE_MASTER_IRQ_CONTROL | DE_GSE_IVB | DE_PCH_EVENT_IVB | - DE_PLANEC_FLIP_DONE_IVB | - DE_PLANEB_FLIP_DONE_IVB | - DE_PLANEA_FLIP_DONE_IVB | - DE_AUX_CHANNEL_A_IVB | - DE_ERR_INT_IVB; - - dev_priv->irq_mask = ~display_mask; - - /* should always can generate irq */ - I915_WRITE(GEN7_ERR_INT, I915_READ(GEN7_ERR_INT)); - I915_WRITE(DEIIR, I915_READ(DEIIR)); - I915_WRITE(DEIMR, dev_priv->irq_mask); - I915_WRITE(DEIER, - display_mask | - DE_PIPEC_VBLANK_IVB | - DE_PIPEB_VBLANK_IVB | - DE_PIPEA_VBLANK_IVB); - POSTING_READ(DEIER); - - gen5_gt_irq_postinstall(dev); - - ibx_irq_postinstall(dev); - - return 0; -} - static int valleyview_irq_postinstall(struct drm_device *dev) { drm_i915_private_t *dev_priv = (drm_i915_private_t *) dev->dev_private; @@ -3040,15 +3020,6 @@ void intel_irq_init(struct drm_device *dev) dev->driver->enable_vblank = valleyview_enable_vblank; dev->driver->disable_vblank = valleyview_disable_vblank; dev_priv->display.hpd_irq_setup = i915_hpd_irq_setup; - } else if (IS_IVYBRIDGE(dev) || IS_HASWELL(dev)) { - /* Share uninstall handlers with ILK/SNB */ - dev->driver->irq_handler = ironlake_irq_handler; - dev->driver->irq_preinstall = ironlake_irq_preinstall; - dev->driver->irq_postinstall = ivybridge_irq_postinstall; - dev->driver->irq_uninstall = ironlake_irq_uninstall; - dev->driver->enable_vblank = ironlake_enable_vblank; - dev->driver->disable_vblank = ironlake_disable_vblank; - dev_priv->display.hpd_irq_setup = ibx_hpd_irq_setup; } else if (HAS_PCH_SPLIT(dev)) { dev->driver->irq_handler = ironlake_irq_handler; dev->driver->irq_preinstall = ironlake_irq_preinstall;
