This is follow up series based on reviews for https://patchwork.freedesktop.org/series/28104/ Major change is assignment of samples at the time of request submission onto HW instead of assigning at user submission time. Restructured patches to make some of the earlier code-heavy patches little lighter by modularizing them. Added new IGT testcase intel_perf_dapc for testing exposed sample fields like PID, Timestamps, CTX ID etc. Reiterating the intent of this series: 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.
