57 * Memory Access Events
59 * Primary PMU event used here is PM_MRK_INST_CMPL (0x401e0)
60 * To enable capturing of memory profiling, these MMCRA bits
61 * needs to be programmed and corresponding raw event format
64 * MMCRA bits encoding needed are
66 * EM (Eligibility for Random Sampling)
67 * TECE (Threshold Event Counter Event)
68 * TS (Threshold Start Event)
69 * TE (Threshold End Event)
71 * Corresponding Raw Encoding bits:
