Apart from some slight naming and grouping differences, the new metrics
are functionally the same as the existing ones. Any missing metrics were
manually appended to the end of the auto generated file.
For the events, the new data includes descriptions that may have product
specific details and new groupings that will be consistent with other
products.
After generating the metrics from the telemetry repo [1], the following
manual steps were performed:
* Change the topdown expressions to compare on CPUID and use
#slots so that the same data can be shared between N2 and V2. Apart
from these modifications, the expressions now match more closely with
the Arm telemetry data which will hopefully make future updates
easier.
* Append some metrics from the old N2/V2 data that aren't present in
the telemetry data. These will possibly be added to the
telemetry-solution repo at a later time:
l3d_cache_mpki, l3d_cache_miss_rate, branch_pki, ipc_rate, spec_ipc,
retired_rate, wasted_rate, branch_immed_spec_rate,
branch_return_spec_rate, branch_indirect_spec_rate
