[PATCH v3 00/16] Add DG2 OA support

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Add OA format support for DG2 and various fixes for DG2.

This series has 2 uapi changes listed below:

1) drm/i915/perf: Add OAG and OAR formats for DG2

DG2 has new OA formats defined that can be selected by the
user. The UMD changes that are consumed by GPUvis are:
https://patchwork.freedesktop.org/patch/504456/?series=107633&rev=5

2) drm/i915/perf: Apply Wa_18013179988

DG2 has a bug where the OA timestamp does not tick at the CS timestamp
frequency. Instead it ticks at a multiple that is determined from the
CTC_SHIFT value in RPM_CONFIG. Since the timestamp is used by UMD to
make sense of all the counters in the report, expose the OA timestamp
frequency to the user. The interface is generic and applies to all
platforms. On platforms where the bug is not present, this returns the
CS timestamp frequency. UMD specific changes consumed by GPUvis are:

v2:
- Add review comments
- Update uapi changes in cover letter
- Drop patches for non-production platforms
drm/i915/perf: Use helpers to process reports w.r.t. OA buffer size
drm/i915/perf: Add Wa_16010703925:dg2

- Drop 64-bit OA format changes for now
drm/i915/perf: Parse 64bit report header formats correctly
drm/i915/perf: Add Wa_1608133521:dg2

v3:
- Add review comments to patches 02, 04, 05, 14
- Drop Acks
