+
+description: |
+ The TPDM or Monitor serves as data collection component for various dataset
+ types specified in the QPMDA spec. It covers Implementation defined ((ImplDef),
+ Basic Counts (BC), Tenure Counts (TC), Continuous Multi-Bit (CMB), and Discrete
+ Single Bit (DSB). It performs data collection in the data producing clock
+ domain and transfers it to the data collection time domain, generally ATB
+ clock domain.
+
+ The primary use case of the TPDM is to collect data from different data
+ sources and send it to a TPDA for packetization, timestamping, and funneling.

Suzuki and Mathieu, we are almost there it seems in getting the
acceptance of these patches, so I hope you find the time to review these
patches. I guess it is almost a year now for these patches and had a
good amount of reviews and revisions :)

This series has been reviewed for the previous versions (which is why
we have it in v12) and this one depends on a series worked on by Mike
Leach. We cannot push this without the dynamic Trace ID allocation
scheme, which is clearly mentioned in the cover letter for this
series.
As such this series is in a good shape, assuming all the comments
in the previous version has been addressed. So, we would rather
get Mike's work priority and pull that in, so that we can eventually
get this upstream.
Kind regards
Suzuki

I believe we have addressed all the comments in v12. Are you ok, if we
post additional features series (around ~2k to ~3k SLOC)? I just want to
make sure we are not creating flood of patches w/ features.

You are free to post the patches, as long as you clearly mention the
dependencies in the cover letter. Please be mindful about the merge window.
