2020-10-14Calculate RSSI offset based on RxGain configurationPau Espin Pedrol1-3/+0
Prior to this patch, osmo-trx relied totally on proper VTY configuration being set in "rssi-offset" together with the RxGain set through TRXC in order to provide correct Uplink RSSI measurements to bts-trx. With this patch, RSSI is now by default calculated (in LMS and UHD backends) based on the currently set RxGain, by providing empirically discovered values. Still, for backward compatibility, the old "rssi-offset" command will overwrite completely the per-default calculated rssi offset. A new optional parameter "relative" is added at the end of the "rssi-offset" VTY command to flag the value as relative to the newly per-default calculated value. This way specific setups (like adding a LNA / RF fronted) can still be expressed while still keeping the automatic per-default offset.

2020-08-25osmo-trx-ipcEric Wild2-0/+36
This adds a IPC backend that uses shared memory interface to communicate with (proprietary) devices. Requires config file option dev-args ipc_msock=/path/to/socket to specify the master socket the ipc backend should connect to. If UHD is avaialble the ipc-driver-test tool can be used to test the backend with a uhd device, this was so far only tested with a b2xx. Change-Id: Ice63d3499026293ade8aad675ff7a883bcdd5756
2020-07-31Use new libosmovty cpu sched config featuresPau Espin Pedrol4-5/+8
Using the new libosmovty features allow for: * Setting different cpu-affinity masks for each thread in the process, both at startup through .cfg file as well as changing it at runtime. * Unified VTY interface to change the scheduling policy of the process inherited by all osmocom processes enabling the feature.

2020-05-23doc: switch log levels to noticePhilipp Maier4-4/+4
Some of the example configs have loglevels set to info. This is too verbose, lets make sure all loglevels are set to notice Change-Id: Ief82b85d9ff0e0e94eaabd255ebea961396fff32
2020-04-14doc: apply an rssi-offset of 28 by default.Philipp Maier1-0/+3
Set an rssi offset of 28 in the example configs to make sure that the power control loop gets RSSI values that match at least half way the reality when the 1800 Mhz band is used. For other bands the value will be different (See also related osmocom ticket) Change-Id: I62725fe454f54e2c7cb7550dadb1e6fc94337d78 Related: OS#4468
2020-04-01doc: do not set the base-port of the trxPhilipp Maier4-4/+0
In current config files a base port for osmo-trx is set. Lets remove this setting so that compiled-in default (which is the same value) is used. Change-Id: I105d1c51424836daa6893e83a81c83cc7ac6afd4
