( https://gerrit.osmocom.org/c/libosmocore/+/41256?usp=email ) Change subject: AMR codec: add conversion between s-bits and codec parameters ...................................................................... AMR codec: add conversion between s-bits and codec parameters At the lowest level of frame information content, before introducing higher layers of RTP or TRAU frame or other encoding, an AMR codec frame (speech or SID) can be represented in 3 fundamental ways: * 35 to 244 s-bits as defined theoretically in TS 26.090 & 26.092 and used in practice in 2G TRAU frames; * 39 to 244 d-bits as defined theoretically in TS 26.101 and used in practice in 3G IuUP and in RTP; * 5 to 57 codec parameters, each fitting into uint16_t, as implemented in 3GPP reference C code (TS 26.073) and assumed by the same spec in its listing of decoder homing frame bit patterns. libosmocodec previously provided conversion functions between s-bits and d-bits, as well as a table that gives the number of d-bits per mode - but no conversion to or from arrays of codec parameters. Add the latter functionality.

falconia has uploaded this change for review. ( https://gerrit.osmocom.org/c/libosmocore/+/41257?usp=email ) Change subject: AMR codec: add decoder homing frame const patterns ...................................................................... AMR codec: add decoder homing frame const patterns ETSI-defined decoder homing frames for HRv1 and EFR are already captured in osmo_gsm620_homing_frame[] and osmo_gsm660_homing_frame[]; now add 3GPP-defined DHFs for AMR, all 8 modes. These AMR DHFs are useful to have in libosmocodec: * Future AMR-capable tw-e1abis-mgw will emit DHFs toward the BTS/CCU during prolonged absence of RTP input - needed because the alternative of emitting an endless stream of No_Data frames may produce undesirable effects on Um with some E1 BTS models. If it is desired to bring tw-e1abis-mgw functionality into mainline Osmocom at some point, DHF bits need to reside somewhere in libosmo*. * In future improvements of AMR support in osmo-bts-trx, it may be likewise desirable to transmit DHFs on Um downlink during the same conditions of prolonged absence of RTP input.

[L] Change in pysim[master]: pySim-shell: add a logger class to centralize logging
by laforge 25 Oct '25

25 Oct '25

laforge has submitted this change. ( https://gerrit.osmocom.org/c/pysim/+/41229?usp=email ) Change subject: pySim-shell: add a logger class to centralize logging ...................................................................... pySim-shell: add a logger class to centralize logging In many sub modules we still use print() to occassionally print status messages or warnings. This technically does not hurt, but it is an unclean solution which we should replace with something more mature. Let's use python's built in logging framework to create a static logger class that fits our needs. To maintain compatibility let's also make sure that the logger class will behave like a normal print() statement when no configuration parameters are supplied by the API user. To illustrate how the approach can be used in sub-modules, this patch replaces the print statements in runtime.py. The other print statements will the be fixed in follow-up patches.

[XS] Change in osmo-ci[master]: OBS: let osmocom-keyring not depend on other pgks
by laforge 25 Oct '25

25 Oct '25

laforge has submitted this change. ( https://gerrit.osmocom.org/c/osmo-ci/+/41255?usp=email ) Change subject: OBS: let osmocom-keyring not depend on other pgks ...................................................................... OBS: let osmocom-keyring not depend on other pgks The osmocom-latest, osmocom-nightly etc. meta-packages depend on the osmocom-keyring package. Fix that the osmocom-keyring package was also depending on these meta packages. This fixes that when uninstalling all osmocom:latest packages by removing the osmocom-latest meta package, the osmocom-keyring package would also get removed. This is undesirable for switching between latest and nightly, as the osmocom-keyring package must remain installed to be able to install new packages from the repository (as it has the repo key).

[S] Change in pysim[master]: pySim-shell: update help strings for chv command parameter --pin-nr
by laforge 25 Oct '25

25 Oct '25

Attention is currently required from: dexter. laforge has posted comments on this change by dexter. ( https://gerrit.osmocom.org/c/pysim/+/41251?usp=email ) Change subject: pySim-shell: update help strings for chv command parameter --pin-nr ...................................................................... Patch Set 1: Code-Review-1 (1 comment) Patchset: PS1: I would rather prefer if we had something more user friendly, translating string names to pin numbers. "0x81" is still somewhat understandable due to the highest bit being set for applicatoin bits, but requiring the uesr then to convert that manually to decimal is just not a good idea. I suggest we use the pySim.ts_102_221.pin_names bidict in this context by default, and accept decimal numeric values only as a compatibility fall-back. -- To view, visit https://gerrit.osmocom.org/c/pysim/+/41251?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: I0b58c402d95cbc4fe690e6edb214829d463e9f2c Gerrit-Change-Number: 41251 Gerrit-PatchSet: 1 Gerrit-Owner: dexter <pmaier(a)sysmocom.de> Gerrit-Reviewer: Jenkins Builder Gerrit-Reviewer: laforge <laforge(a)osmocom.org> Gerrit-Reviewer: osmith <osmith(a)sysmocom.de> Gerrit-Attention: dexter <pmaier(a)sysmocom.de> Gerrit-Comment-Date: Sat, 25 Oct 2025 19:40:33 +0000 Gerrit-HasComments: Yes Gerrit-Has-Labels: Yes

[S] Change in osmo-trx[master]: trx: Fix tx/rx-sps 4 for USRP1 devices
by laforge 25 Oct '25

laforge has submitted this change. ( https://gerrit.osmocom.org/c/osmo-trx/+/41231?usp=email ) Change subject: trx: Fix tx/rx-sps 4 for USRP1 devices ...................................................................... trx: Fix tx/rx-sps 4 for USRP1 devices The existing code sets the pingOffset variable to -7231(269 - 7500) with tx-sps = 4. The (apparent) correct value for pingOffset for tx/rx-sps 4 is 272. While I'm not completely sure how this patch works to fix the increased sps value, my theory is that the original OpenBTS TRX only supported a split sps setup(tx-sps=4, rx_sps=1 for sps=4), which created differing decimation rates between Tx and Rx on the board. In this case, apparently you needed to account for an advance in the timestamp for a correct output. With tx_sps == rx_sps, the decimation/sample rates will be the same, and(I guess) this advance doesn't need to be accounted for. Also changed a line in the initialization of the Rx end of the USRP device to use the correct decimation rate when tx/rx-sps == 4. Since osmo-trx won't allow nonequal values for tx-sps and rx-sps, I commented out the logic that selected pingOffset based on sps. I left it visible in the file for reference however. Tested & working on the URAN-1, a USRP1 clone designed for GSM.
