From c0d6a3dd61d46a640ead0a9d38b78ca22d37a304 Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Thu, 4 Jul 2013 23:35:30 +0200 Subject: [PATCH] drm/i915: don't enable PM_VEBOX_CS_ERROR_INTERRUPT The code to handle it is broken - there's simply no code to clear CS parser errors on gen5+. And behold, for all the other rings we also don't enable it! Leave the handling code itself in place just to be consistent with the existing mess though. And in case someone feels like fixing it all up. This has been errornously enabled in commit 12638c57f31952127c734c26315e1348fa1334c2 Author: Ben Widawsky Date: Tue May 28 19:22:31 2013 -0700 drm/i915: Enable vebox interrupts Cc: Damien Lespiau Cc: Ben Widawsky Reviewed-by: Ben Widawsky Signed-off-by: Daniel Vetter --- drivers/gpu/drm/i915/i915_irq.c | 3 +-- drivers/gpu/drm/i915/intel_ringbuffer.c | 3 +-- 2 files changed, 2 insertions(+), 4 deletions(-) diff --git a/drivers/gpu/drm/i915/i915_irq.c b/drivers/gpu/drm/i915/i915_irq.c index f4d5569..cf1a21a 100644 --- a/drivers/gpu/drm/i915/i915_irq.c +++ b/drivers/gpu/drm/i915/i915_irq.c @@ -2814,8 +2814,7 @@ static int ivybridge_irq_postinstall(struct drm_device *dev) I915_WRITE(GEN6_PMIIR, I915_READ(GEN6_PMIIR)); if (HAS_VEBOX(dev)) - pm_irqs |= PM_VEBOX_USER_INTERRUPT | - PM_VEBOX_CS_ERROR_INTERRUPT; + pm_irqs |= PM_VEBOX_USER_INTERRUPT; /* Our enable/disable rps functions may touch these registers so * make sure to set a known state for only the non-RPS bits. diff --git a/drivers/gpu/drm/i915/intel_ringbuffer.c b/drivers/gpu/drm/i915/intel_ringbuffer.c index 23ffe1d..815e303 100644 --- a/drivers/gpu/drm/i915/intel_ringbuffer.c +++ b/drivers/gpu/drm/i915/intel_ringbuffer.c @@ -2000,8 +2000,7 @@ int intel_init_vebox_ring_buffer(struct drm_device *dev) ring->add_request = gen6_add_request; ring->get_seqno = gen6_ring_get_seqno; ring->set_seqno = ring_set_seqno; - ring->irq_enable_mask = PM_VEBOX_USER_INTERRUPT | - PM_VEBOX_CS_ERROR_INTERRUPT; + ring->irq_enable_mask = PM_VEBOX_USER_INTERRUPT; ring->irq_get = hsw_vebox_get_irq; ring->irq_put = hsw_vebox_put_irq; ring->dispatch_execbuffer = gen6_ring_dispatch_execbuffer; -- 2.7.4
