MI_BATCH_BUFFER_START predicates based on MI_SET_PREDICATE_RESULT register. The MI_SET_PREDICATE_RESULT register can only be modified with MI_SET_PREDICATE command. When configured, the MI_SET_PREDICATE command sets MI_SET_PREDICATE_RESULT based on bit 0 of MI_PREDICATE_RESULT_2. Use this to configure predication in noa_wait.

The calculation relies on the CS timestamp frequency to convert the timestamp value to nanoseconds. The CS timestamp frequency is a function of the CTC_SHIFT value in RPM_CONFIG0. In DG2, OA unit assumes that the CTC_SHIFT is 3, instead of using the actual value from RPM_CONFIG0. At the user level, this results in an error in calculating delta between 2 OA reports since the OA timestamp is not shifted in the same manner as CS timestamp. Also the periodicity of the reports is different from what the user configured because of mismatch in the CS and OA frequencies. The issue also affects MI_REPORT_PERF_COUNT command. To resolve this, return actual OA timestamp frequency to the user in i915_getparam_ioctl, so that user can calculate the right OA exponent as well as interpret the reports correctly.

This reset clears the EU flex counter configuration. If an OA use case is running in parallel, it would start seeing zeroed eu counter values following the reset even if the drm client is restarted. Save/restore the EU flex counter config so that the EU counters can be monitored continuously across resets. v2: - Save/restore eu flex config only for gen12, as for pre-gen12, these are saved and restored in the context image.
