fyi, neels accounts mixup solved
by Neels Hofmeyr 11 Aug '16

11 Aug '16

Today I've solved the recent weird mixup in gerrit of my main sysmocom account "nhofmeyr" and my private mail address account "neels_test_account". For some time now I've been marking my commits as neels(a)hofmeyr.de, which should have been nhofmeyr(a)sysmocom.de. The config is now fixed in my various git repositories and my future commits should be authored as nhofmeyr. If you spot another neels(a)hofmeyr.de, that's a bug :) ~Neels -- - Neels Hofmeyr <nhofmeyr(a)sysmocom.de> http://www.sysmocom.de/ ======================================================================= * sysmocom - systems for mobile communications GmbH * Alt-Moabit 93 * 10559 Berlin, Germany * Sitz / Registered office: Berlin, HRB 134158 B * Geschäftsführer / Managing Directors: Harald Welte

CI infrastructure changes
by Holger Freyther 09 Aug '16

09 Aug '16

Hi, the CI infrastructure exists because I found it import to have all Osmocom software compile and I set-up the Jenkins on my personal infrastructure. Since the adoption of gerrit having a stable build infrastructure is crucial though and my set-up was too flawed. In the past the VirtualBox running the Linux node got stuck and needed manual intervention. As it was running on my private system I was the only one capable of doing that. Sysmocom has offered to rent a dedicated build system and I have used some of my freelancing time to do the migration. * The Jenkins UI/Server jail has been migrated to the system that runs most of the other Osmocom infrastructure. DNS should be updated soon and then TLS will be enabled for the login. * OsmocomBuild1 is a Debian8.0/amd64 build slave with plenty of RAM and running on a SSD. All Linux builds should have been migrated away from the Ubuntu-1504-64 system to it. * rtl-sdr has some funny issue with make uninstall and Doxygen. If someone wants to fix it please go ahead, otherwise I will probably disable doxygen for this build. * I tried to have OpenBSC/OpenBSC-gerrit run in docker[1] so we can run all configurations at the same time but Jenkins is stepping on itself (and removing files from one label and impacting the other). At least we seem to have a benefit if two people upload changes at the same time. kind regards holger [1] I would prefer something without a server (as aborting a build doesn't abort the container) but still convenient enough to just create a new network namespace and remove it on exit [2] We are only executing the four configurations in parallel as the "build concurrently" option is stepping on each other (files vanish, etc).

[PATCH] remove INSTALL file to have a clean git status
by Neels Hofmeyr 08 Aug '16

08 Aug '16

From: Neels Hofmeyr <neels(a)hofmeyr.de> The INSTALL file is being overwritten by autoreconf, but it is committed as empty file. As a result, the INSTALL file always shows as modified.

Development of rtl-sdr driver
by Piotr Krysik 08 Aug '16

08 Aug '16

Hi everyone, The osmocom's version of rtl-sdr driver seems to be the main one. Osmocom's repository is used by distributions to build rtl-sdr packages and it is source of the code for compilation with use of GNU Radio's Pybombs. Is there someone in the Osmocom who is maintaining it? There were some important developments regarding this driver and it would be great to add this patches in the Osmocom's repo. For example one that interests me is turning off dithering so multiple dongles sharing the same clock generate the same LO frequency.Currently there is always little frequency offset that makes coherent of the receivers operation much harder. Such changes of course have to be done carefully so nothing gets broken in the process. In case of turning off dithering it results with worse tuning granularity, so for example turning it off can be made optional. -- Best Regards, Piotr Krysik

signal quality measurements in osmo-trx
by Max 04 Aug '16

04 Aug '16

Hi. I'm working on http://projects.osmocom.org/issues/1616 and wonder about $subj. In case of sysmobts, osmo-pcu obtain this data directly from DSP: * RSSI (dBm) * burst timing (in quarter of bits) * link quality (in dB) * BER The first and last value seems to be easy from what I see in src/osmo-bts-trx/scheduler_trx.c What about burst timing (necessary to compute TA in the absence of PTCCH) and link quality (measure of C / I where C is carrier and I is interference power) - how can I compute those or some estimator to those values? -- Max Suraev <msuraev(a)sysmocom.de> http://www.sysmocom.de/ ======================================================================= * sysmocom - systems for mobile communications GmbH * Alt-Moabit 93 * 10559 Berlin, Germany * Sitz / Registered office: Berlin, HRB 134158 B * Geschaeftsfuehrer / Managing Director: Harald Welte

control interface variable naming
by Max 03 Aug '16

03 Aug '16

Hi. It's nitpicking time :) I've noticed that variables exposed over control interface (see osmobsc-usermanual.pdf for example) are named differently - some use _ (e. g. bts_connection_status) others use - (e. g. short-name). Which variant is preferred if any? -- Max Suraev <msuraev(a)sysmocom.de> http://www.sysmocom.de/ ======================================================================= * sysmocom - systems for mobile communications GmbH * Alt-Moabit 93 * 10559 Berlin, Germany * Sitz / Registered office: Berlin, HRB 134158 B * Geschaeftsfuehrer / Managing Director: Harald Welte
