OpenCSD version 1.4 is released with support for FEAT_ITE. This adds a new packet type, with associated output element ID in the packet type enum - OCSD_GEN_TRC_ELEM_INSTRUMENTATION.

As we just ignore this packet in perf, add to the switch statement to avoid the "enum not handled in switch error", but conditionally so as not to break the perf build for older OpenCSD installations.

Checked the build with both old and new versions of OpenCSD and it's ok:

Thanks, Ian

Hi Arnaldo,

Is it ok to merge this change? If anyone is building with the latest OpenCSD they will get a build error on the unhandled switch case, and we just got it in our CI too.

I suppose we could disable the warning around this switch, but it's pretty rare to add new packets so might be best to leave it.

Thanks, applied.
