2018-05-03T09:49:18+00:00

Almost everyone uses dma_fence_default_wait.

dma-fence: Make ->enable_signaling optional

2018-05-03T09:48:22+00:00

Many drivers have a trivial implementation for ->enable_signaling. Let's make it optional by assuming that signalling is already available when the callback isn't present.

dma-fence: remove fill_driver_data callback

2018-05-03T09:47:42+00:00

Noticed while I was typing docs. Entirely unused. v2: Remove reference in @timeline_value_str too. While at it clarify why timeline_value_str has a fence parameter - we don't have an explicit timeline structure unfortunately.

dma-fence: Some kerneldoc polish for dma-fence.h

2018-05-02T08:00:37+00:00

- Switch to inline member docs for dma_fence_ops. - Mild polish all around. - hyperlink all the things! v2: - Remove the various [in] annotations, they seem really uncommon in kerneldoc and look funny. v3: Linebreak the "Returns" part of the @fill_driver_data kerneldoc (Eric).

dma-buf/fence: Sparse wants __rcu on the object itself

2017-11-09T18:32:53+00:00

In order to silence sparse in dma_fence_get_rcu_safe(), we need to mark the incoming fence object as being RCU protected and not the pointer to the object.

dma-fence: fix dma_fence_get_rcu_safe v2

2017-10-09T15:14:05+00:00

When dma_fence_get_rcu() fails to acquire a reference it doesn't necessary mean that there is no fence at all. It usually mean that the fence was replaced by a new one and in this situation we certainly want to have the new one as result and *NOT* NULL. v2: Keep extra check after dma_fence_get_rcu().
