Most of the checks just look for PCH split availability, and block the call to PCH interrupt functions if not available. v2: (jani) - drop redundant TODO comment about PCH IRQ flags on BXT - check HAS_PCH_SPLIT instead of IS_BROXTON when handling PCH specific IRQ events in gen8_irq_handler() - check HAS_PCH_SPLIT before calling the function instead of a corresponding early return within the called function for ibx_irq_reset(), ibx_irq_pre_postinstall(), ibx_irq_postinstall() v3: (jani) - in ironlake_irq_postinstall() and ironlake_irq_reset() HAS_PCH_SPLIT is always true, so drop the check for it Reviewed-by: Satheeshakrishna M Signed-off-by: Damien Lespiau Signed-off-by: Shashank Sharma (v1) Signed-off-by: Imre Deak Reviewed-by: Jani Nikula Signed-off-by: Daniel Vetter --- diff --git a/drivers/gpu/drm/i915/i915_irq.c b/drivers/gpu/drm/i915/i915_irq.c index ac68b5bd8f15..17a8f8c61753 100644 --- a/drivers/gpu/drm/i915/i915_irq.c +++ b/drivers/gpu/drm/i915/i915_irq.c @@ -2297,7 +2297,8 @@ static irqreturn_t gen8_irq_handler(int irq, void *arg) DRM_ERROR("The master control interrupt lied (DE PIPE)!\n"); } - if (!HAS_PCH_NOP(dev) && master_ctl & GEN8_DE_PCH_IRQ) { + if (HAS_PCH_SPLIT(dev) && !HAS_PCH_NOP(dev) && + master_ctl & GEN8_DE_PCH_IRQ) { /* * FIXME(BDW): Assume for now that the new interrupt handling * scheme also closed the SDE interrupt handling race we've seen @@ -3133,7 +3134,8 @@ static void gen8_irq_reset(struct drm_device *dev) GEN5_IRQ_RESET(GEN8_DE_MISC_); GEN5_IRQ_RESET(GEN8_PCU_); - ibx_irq_reset(dev); + if (HAS_PCH_SPLIT(dev)) + ibx_irq_reset(dev); } void gen8_irq_power_well_post_enable(struct drm_i915_private *dev_priv, @@ -3545,12 +3547,14 @@ static int gen8_irq_postinstall(struct drm_device *dev) { struct drm_i915_private *dev_priv = dev->dev_private; - ibx_irq_pre_postinstall(dev); + if (HAS_PCH_SPLIT(dev)) + ibx_irq_pre_postinstall(dev); gen8_gt_irq_postinstall(dev_priv); gen8_de_irq_postinstall(dev_priv); - ibx_irq_postinstall(dev); + if (HAS_PCH_SPLIT(dev)) + ibx_irq_postinstall(dev); I915_WRITE(GEN8_MASTER_IRQ, DE_MASTER_IRQ_CONTROL); POSTING_READ(GEN8_MASTER_IRQ);
