This series is prepared from below two series posted by Sourab in March. 1. https://patchwork.freedesktop.org/series/21351/ - Collect command stream based OA reports using i915 perf 2. https://patchwork.freedesktop.org/series/21352/ - Collect command stream based GPU metrics for all engines using i915 perf This series addresses most of the review comments from above two. Major change is moving the stream structure and information from dev_priv to per-engine structures. Stating below the intent of this series from cover letters of earlier series. This series adds framework for 1. Collection of OA reports associated with the render command stream, which are collected around batchbuffer boundaries. 2. Collect other metadata such as ctx_id, pid, tag etc. with the samples, and thus we can establish the association of samples collected with the corresponding process/workload. 3. Collection of GPU performance metrics associated with the command stream of a particular engine. These metrics include timestamps of work submission and completion on engines, mmio metrics, etc. These metrics are are collected around batchbuffer boundaries. Functionality to be added in future patches: 1. GPU/CPU cross-timestamp sync patches need to be reworked as requested by kernel maintainers. 2. Some of the data types being collected through these patches can be done in the userspace and that is yet to be finalized. Based on that some of the functionality from this series can be pruned. 3. Add support in the perf IGT tests for verifying CS based perf functionality.
