    perf vendor events amd: Update Zen1 events to V2 · b5b8a7cf
    Vijay Thakkar authored
    This patch updates the PMCs for AMD Zen1 core based processors (Family
    17h; Models 0 through 2F) to be in accordance with PMCs as
    documented in the latest versions of the AMD Processor Programming
    Reference [1], [2] and [3]. Note that some events, such as FPU pipe
    assignment are missing in [1], and therefore [3] is included for full
    coverage of events.
    
    PMCs added:
    
      fpu_pipe_assignment.dual{0|1|2|3}
      fpu_pipe_assignment.total{0|1|2|3}
      ls_mab_alloc.dc_prefetcher
      ls_mab_alloc.stores
      ls_mab_alloc.loads
      bp_dyn_ind_pred
      bp_de_redirect
    
    PMC removed:
    
      ex_ret_cond_misp
    
    Cumulative counts, fpu_pipe_assignment.total and
    fpu_pipe_assignment.dual, existed in v1, but did expose port-level
    counters.
    
    ex_ret_cond_misp has been removed as it has been removed from the latest
    versions of the PPR, and when tested, always seems to sample zero as
    tested on a Ryzen 3400G system.
