* dma-fence: Allow wait_any_timeout for all fencesDaniel Vetter2018-07-021-5/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When this was introduced in commit a519435a96597d8cd96123246fea4ae5a6c90b02 Author: Christian König <christian.koenig@amd.com> Date: Tue Oct 20 16:34:16 2015 +0200 dma-buf/fence: add fence_wait_any_timeout function v2 there was a restriction added that this only works if the dma-fence uses the dma_fence_default_wait hook. Which works for amdgpu, which is the only caller. Well, until you share some buffers with e.g. i915, then you get an -EINVAL. But there's really no reason for this, because all drivers must support callbacks. The special ->wait hook is only as an optimization; if the driver needs to create a worker thread for an active callback, then it can avoid to do that if it knows that there's a process context available already. So ->wait is just an optimization, just using the logic in dma_fence_default_wait() should work for all drivers. Let's remove this restriction.

* dma-fence: Make ->enable_signaling optionalDaniel Vetter2018-07-021-4/+5
| | | | | | | | | | | | | | | | | | | | | | | 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. v2: Don't do the trick to set the ENABLE_SIGNAL_BIT unconditionally, it results in an expensive spinlock take for everyone. Instead just check if the callback is present. Suggested by Maarten. Also move misplaced kerneldoc hunk to the right patch.

* tracing, dma-buf: Remove unused trace event dma_fence_annotate_wait_onSteven Rostedt (VMware)2017-10-161-1/+0
| | | | | | | | | | | | | | | Commit e941759c74 ("fence: dma-buf cross-device synchronization") added trace event fence_annotate_wait_on, but never used it. It was renamed to dma_fence_annotate_wait_on by commit f54d186700 ("dma-buf: Rename struct fence to dma_fence") but still not used. As defined trace events have data structures and functions created for them, it is a waste of memory if they are not used. Remove the unused trace event.

It is done before to avoid observers having a window in which they may see the fence as complete but no timestamp. Having it does incur a potential for the timestamp to be written twice, and even for it to be corrupted if the u64 write is not atomic. Instead use a new bit to record the presence of the timestamp, and teach the readers to wait until it is set if the fence is complete. There still remains a race where the timestamp for the signaled fence may be shown before the fence is reported as signaled, but that's a pre-existing error.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When a timeout of zero is specified, the caller is only interested in the fence status. In the current implementation, dma_fence_default_wait will always call schedule_timeout() at least once for an unsignaled fence. This adds a significant overhead to a fence status query.

| | | | | | | | | | | | | | | | | | | | The dma_fence.error field (formerly known as dma_fence.status) is an optional field that may be set by drivers before calling dma_fence_signal(). The field can be used to indicate that the fence was completed in err rather than with success, and is visible to other consumers of the fence and to userspace via sync_file. This patch renames the field from status to error so that its meaning is hopefully more clear (and distinct from dma_fence_get_status() which is a composite between the error state and signal state) and adds a helper that validates the preconditions of when it is suitable to adjust the error field.

* dma-buf: Rename struct fence to dma_fenceChris Wilson2016-10-251-0/+537
I plan to usurp the short name of struct fence for a core kernel struct, and so I need to rename the specialised fence/timeline for DMA operations to make room. A consensus was reached in https://lists.freedesktop.org/archives/dri-devel/2016-July/113083.html that making clear this fence applies to DMA operations was a good thing. Since then the patch has grown a bit as usage increases, so hopefully it remains a good thing!
