Given that runtime instrumentation using PMF is invasive, there is a small
(unquantified) overhead on the results. PMF uses the generic counter for
timestamps, which runs at 50MHz on Juno.
The following source trees and binaries were used:
- `TF-A v2.14-rc0`_
- `TFTF v2.14-rc0`_
timestamps, which runs at 50MHz on Juno. Testing was done after the rc0 tag.

=======================================
For this test we used the N1 System Development Platform (`N1SDP`_), which
contains an SoC consisting of two dual-core Arm N1 clusters.
The following source trees were used:
- `TF-A v2.14-rc0`_
- `TFTF v2.14-rc0`_
contains an SoC consisting of two dual-core Arm N1 clusters. Testing was done
after the rc0 tag.
Please see the Runtime Instrumentation :ref:`Testing Methodology
