From: Chris Wilson Date: Tue, 29 Mar 2011 12:19:09 +0000 (+0100) Subject: drm/i915: Move the irq wait queue initialisation into the ring init X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=b259f6730c09bc356df932ba9188f291de816808;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git drm/i915: Move the irq wait queue initialisation into the ring init Required so that we don't obliterate the queue if initialising the rings after the global IRQ handler is installed. [Jesse, you recently looked at refactoring the IRQ installation routines, does moving the initialisation of ring buffer data structures away from that routine make sense in your grand scheme?] Signed-off-by: Chris Wilson Cc: Jesse Barnes Reviewed-by: Ben Widawsky Signed-off-by: Keith Packard --- diff --git a/drivers/gpu/drm/i915/i915_irq.c b/drivers/gpu/drm/i915/i915_irq.c index 188b497e5076..46ccfc814ea7 100644 --- a/drivers/gpu/drm/i915/i915_irq.c +++ b/drivers/gpu/drm/i915/i915_irq.c @@ -1688,12 +1688,6 @@ int i915_driver_irq_postinstall(struct drm_device *dev) u32 enable_mask = I915_INTERRUPT_ENABLE_FIX | I915_INTERRUPT_ENABLE_VAR; u32 error_mask; - DRM_INIT_WAITQUEUE(&dev_priv->ring[RCS].irq_queue); - if (HAS_BSD(dev)) - DRM_INIT_WAITQUEUE(&dev_priv->ring[VCS].irq_queue); - if (HAS_BLT(dev)) - DRM_INIT_WAITQUEUE(&dev_priv->ring[BCS].irq_queue); - dev_priv->vblank_pipe = DRM_I915_VBLANK_PIPE_A | DRM_I915_VBLANK_PIPE_B; if (HAS_PCH_SPLIT(dev)) diff --git a/drivers/gpu/drm/i915/intel_ringbuffer.c b/drivers/gpu/drm/i915/intel_ringbuffer.c index e9e6f71418a4..884556d9814e 100644 --- a/drivers/gpu/drm/i915/intel_ringbuffer.c +++ b/drivers/gpu/drm/i915/intel_ringbuffer.c @@ -800,6 +800,7 @@ int intel_init_ring_buffer(struct drm_device *dev, INIT_LIST_HEAD(&ring->request_list); INIT_LIST_HEAD(&ring->gpu_write_list); + init_waitqueue_head(&ring->irq_queue); spin_lock_init(&ring->irq_lock); ring->irq_mask = ~0;
