pespin has uploaded this change for review. ( https://gerrit.osmocom.org/c/docker-playground/+/41777?usp=email ) Change subject: bpftrace: Introduce ksys_write_delay.bt ...................................................................... bpftrace: Introduce ksys_write_delay.bt This will record latency of write() calls during ttcn3-bts-test run, where some write() call on stderr seems to be taking ~0.32 seconds, stalling the timerfd (71 times) and making osmo-bts exit.

[M] Change in pysim[master]: personalization: implement reading back values from a PES

Attention is currently required from: neels. laforge has posted comments on this change by neels. ( https://gerrit.osmocom.org/c/pysim/+/40198?usp=email ) Change subject: personalization: implement reading back values from a PES ...................................................................... Patch Set 6: Code-Review-1 (1 comment) File pySim/esim/saip/personalization.py: https://gerrit.osmocom.org/c/pysim/+/40198/comment/c352d841_200e6677?usp=em… : PS6, Line 56: de this is somewhat of a copy of pySim.esim.saip.File.file_content_from_tuples, and I think it's a dangerously incomplete one as it does not understand anything about default file contents "inherited" from the specific file template that may be used for a file. In general I think the proper approach for this is to simply use the existing high-level infrsatructure from the @File()@ instances that are attached to the ProfileElementSeequence, rather than doing a functionally limited re-implementation of it here. The added benefit is reduced code duplication, but even more relevant: You get the proper default file contents from the filesystem template, if any was used by the specific input profile. -- To view, visit https://gerrit.osmocom.org/c/pysim/+/40198?usp=email To unsubscribe, or for help writing mail filters, visit https://gerrit.osmocom.org/settings?usp=email Gerrit-MessageType: comment Gerrit-Project: pysim Gerrit-Branch: master Gerrit-Change-Id: I234fc4317f0bdc1a486f0cee4fa432c1dce9b463 Gerrit-Change-Number: 40198 Gerrit-PatchSet: 6 Gerrit-Owner: neels <nhofmeyr(a)sysmocom.de> Gerrit-Reviewer: Jenkins Builder Gerrit-Reviewer: laforge <laforge(a)osmocom.org> Gerrit-Attention: neels <nhofmeyr(a)sysmocom.de> Gerrit-Comment-Date: Wed, 07 Jan 2026 12:49:24 +0000 Gerrit-HasComments: Yes Gerrit-Has-Labels: Yes
