Since there are multiple platform variants for AM62x.
Please document clearly on which board the performance numbers are captured on.
Under
"The latencies observed with this SDK are summarized below:"
may be update as
"The latencies observed with this default yocto SDK image on https://www.ti.com/tool/SK-AM62B-P1 and are summarized below:"

bryanbrattlof · 2025-07-10T14:27:10Z

Yeah I agree @praneethbajjuri . I've updated that sentence to be a little more specific.

StaticRocket · 2025-07-10T21:20:09Z

Could you address the vale comments?

praneethbajjuri

lets hold off on integration of this . Till the investigation completes on why latency numbers changed.
Might need to expand this PR to include the rootcause and workaround details to get better perf numbers.

@dao-qiu please review

praneethbajjuri · 2025-10-02T19:11:11Z

@bryanbrattlof can you update in commitmsg and histogram as well on what is the exact tag used for a given device to get this numbers.
Example:
AM62A 11.1 is RC7
AM62P/62/64/ 11.1 is RC5
AM62L 11.1 and AM62P 11.1.1 is RC16 ( Wait till this PR is merged #459 )

Those rstcheck errors are valid. Seems like the template needs to be adjusted.

@bryanbrattlof Is there any feedback on the exact RCs used for the cyclictest results?

From Bryan: I updated all the graphs to include which release candidate was used by each board

In certain highly specific use-cases the TRNG drivers in OPTEE could have unwanted affects to the overall system if the application cares more about deterministic latency over entropy. Provide a section to document how to easily switch from the true RNG drivers to pseudo RNG drivers. Signed-off-by: Bryan Brattlof <bb@ti.com>

Ah sorry (I didn't see a reponse dialog and skipped it) yep I've updated the graphs to indicate which release candidate was used for each
