| | | | | | | | | | | | | Add xgmi perfmons for Arcturus. v4: Align with patch 2 with struct improvements v3: Align with patch 2 streamlining perf types versus event config types. v2: Resend for re-review with alignment for v3 in patch 2.

* drm/amdgpu: add per device user friendly xgmi events for vega20Jonathan Kim2020-10-071-59/+375
| | | | | | | | | | | | | | | | | | | | | | | | | Non-outbound data metrics are non useful so mark them as legacy. Bucket new perf counters into device and not device ip. Bind events to chip instead of IP. Report available event counters and not number of hw counter banks. Move DF public macros to private since not needed outside of IP version. v5: cleanup by moving per chip configs into structs v4: After more discussion, replace *_LEGACY references with IP references to indicate concept of pmu-typed versus event-config-typed event registration. v3: attr groups const array is global but attr groups are allocated per device which doesn't work and causes problems on memory allocation and de-allocation for pmu unregister. Switch to building const attr groups per pmu instead to simplify solution. v2: add comments on sysfs structure and formatting.

| | | | | | | | | | | | Mapping hw counters per event config will cause ABA problems so map per event instead. v2: Discontinue starting perf counters if add fails. Make it clear what's happening with pmc_start.

* drm/amdgpu: fix amdgpu pmu to use hwc->config instead of hwc->confJonathan Kim2020-02-111-7/+8
| | | | | | | | | | | | hwc->conf was designated specifically for AMD APU IOMMU purposes. This could cause problems in performance and/or function since APU IOMMU implementation is elsewhere. Also hwc->conf and hwc->config are different members of an anonymous union so hwc->conf aliases as hw->last_tag.

* drm/amdgpu: Create generic DF struct in adevJoseph Greathouse2020-01-141-6/+6
| | | | | | | | | | | | | The only data fabric information the adev struct currently contains is a function pointer table. In the near future, we will be adding some cached DF information into adev. As such, this patch creates a new amdgpu_df struct for adev. Right now, it only containst the old function pointer table, but new stuff will be added soon.
