drm/i915: Double check the active status on the batch pool

2016-08-04T19:19:50Z

We should not rely on obj->active being uptodate unless we manually flush it. Instead, we can verify that the next available batch object is idle by looking at its last active request (and checking it for completion). v2: remove the struct drm_device forward declaration added in the process of removing its necessity Signed-off-by: Chris Wilson Reviewed-by: Joonas Lahtinen Link: http://patchwork.freedesktop.org/patch/msgid/1470324762-2545-3-git-send-email-chris@chris-wilson.co.uk

drm/i915: Split batch pool into size buckets

2015-04-10T06:56:05Z

Now with the trimmed memcpy before the command parser, we try to allocate many different sizes of batches, predominantly one or two pages. We can therefore speed up searching for a good sized batch by keeping the objects of buckets of roughly the same size. v2: Add a comment about bucket sizes Signed-off-by: Chris Wilson Reviewed-by: Tvrtko Ursulin

drm/i915: Split i915_gem_batch_pool into its own header

2015-04-10T06:56:03Z

In the next patch, I want to use the structure elsewhere and so require it defined earlier. Rather than move the definition to an earlier location where it feels very odd, place it in its own header file. Signed-off-by: Chris Wilson Reviewed-by: Tvrtko Ursulin Signed-off-by: Daniel Vetter
