From a15817cf16081b140e105736c9a6a50af38540b3 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Fri, 11 May 2012 14:29:31 +0100 Subject: [PATCH] drm/i915: Check whether the ring is initialised prior to dispatch Rather than use the magic feature tests HAS_BLT/HAS_BSD just check whether the ring we are about to dispatch the execbuffer on is initialised. v2: Use intel_ring_initialized() Signed-off-by: Chris Wilson Reviewed-by: Ben Widawsky Signed-off-by: Daniel Vetter --- drivers/gpu/drm/i915/i915_gem_execbuffer.c | 13 +++++-------- 1 file changed, 5 insertions(+), 8 deletions(-) diff --git a/drivers/gpu/drm/i915/i915_gem_execbuffer.c b/drivers/gpu/drm/i915/i915_gem_execbuffer.c index 21fc11d84712..974a9f1068a3 100644 --- a/drivers/gpu/drm/i915/i915_gem_execbuffer.c +++ b/drivers/gpu/drm/i915/i915_gem_execbuffer.c @@ -1064,17 +1064,9 @@ i915_gem_do_execbuffer(struct drm_device *dev, void *data, ring = &dev_priv->ring[RCS]; break; case I915_EXEC_BSD: - if (!HAS_BSD(dev)) { - DRM_DEBUG("execbuf with invalid ring (BSD)\n"); - return -EINVAL; - } ring = &dev_priv->ring[VCS]; break; case I915_EXEC_BLT: - if (!HAS_BLT(dev)) { - DRM_DEBUG("execbuf with invalid ring (BLT)\n"); - return -EINVAL; - } ring = &dev_priv->ring[BCS]; break; default: @@ -1082,6 +1074,11 @@ i915_gem_do_execbuffer(struct drm_device *dev, void *data, (int)(args->flags & I915_EXEC_RING_MASK)); return -EINVAL; } + if (!intel_ring_initialized(ring)) { + DRM_DEBUG("execbuf with invalid ring: %d\n", + (int)(args->flags & I915_EXEC_RING_MASK)); + return -EINVAL; + } mode = args->flags & I915_EXEC_CONSTANTS_MASK; mask = I915_EXEC_CONSTANTS_MASK; -- 2.30.2
