Track the latest fence waited upon on each context, and only add a new asynchronous wait if the new fence is more recent than the recorded fence for that context. This requires us to filter out unordered timelines, which are noted by DMA_FENCE_NO_CONTEXT. However, in the absence of a universal identifier, we have to use our own i915->mm.unordered_timeline token. v2: Throw around the debug crutches v3: Inline the likely case of the pre-allocation cache being full. v4: Drop the pre-allocation support, we can lose the most recent fence in case of allocation failure -- it just means we may emit more awaits than strictly necessary but will not break. v5: Trim allocation size for leaf nodes, they only need an array of u32 not pointers. v6: Create mock_timeline to tidy selftest writing v7: s/intel_timeline_sync_get/intel_timeline_sync_is_later/ (Tvrtko) v8: Prune the stale sync points when we idle. v9: Include a small benchmark in the kselftests v10: Separate the idr implementation into its own compartment. (Tvrkto) v11: Refactor igt_sync kselftests to avoid deep nesting (Tvrkto) v12: __sync_leaf_idx() to assert that p->height is 0 when checking leaves v13: kselftests to investigate struct i915_syncmap itself (Tvrtko) v14: Foray into ascii art graphs v15: Take into account that the random lookup/insert does 2 prng calls, not 1, when benchmarking, and use for_each_set_bit() (Tvrtko) v16: Improved ascii art Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Cc: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Cc: Joonas Lahtinen <joonas.lahtinen@linux.intel.com> Reviewed-by: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/20170503093924.5320-4-chris@chris-wilson.co.uk
