Hello Jenkins Builder, pespin,

I'd like you to reexamine a change. Please visit

https://gerrit.osmocom.org/c/osmocom-bb/+/39537?usp=email

to look at the new patch set (#2).

The following approvals got outdated and were removed: Code-Review+1 by pespin, Verified+1 by Jenkins Builder

Change subject: trx_toolkit/*: Try to avoid copying burst data where possible ......................................................................

trx_toolkit/*: Try to avoid copying burst data where possible

Conveying burst data is the primary flow in data place of what fake_trx does, so the less copies we do, the less we make CPU loaded.

After this change I can finally run 1 BTS + 2 Mobile + 1 ccch_scan without hitting "Stale message ..." on fake_trx side. However fake_trx cpu load is close to 100% and there are internal clock overruns often:

[WARNING] clck_gen.py:97 CLCKGen: time overrun by -1385us; resetting the clock [WARNING] clck_gen.py:97 CLCKGen: time overrun by -2657us; resetting the clock [WARNING] clck_gen.py:97 CLCKGen: time overrun by -1264us; resetting the clock [WARNING] clck_gen.py:97 CLCKGen: time overrun by -2913us; resetting the clock [WARNING] clck_gen.py:97 CLCKGen: time overrun by -1836us; resetting the clock ...

This suggests that even though fake_trx.py + tx-queue started to work somehow, the rewrite of fake_trx in C, as explained in OS#6672, is still better to do.
