Harald Welte f1fb0fa3af Merge branch '201509-trx-rebase' 2015-09-22 16:41:54 +02:00
Harald Welte caa648d92e TRX: Add missing call to abis_init() 
This somehow got lost during the latest rebase.

Harald Welte 88a31e2a99 make osmo-bts-trx provide bts_model_adjst_ms_pwr() 2015-09-22 16:41:32 +02:00
Harald Welte 307bfc81c1 fixup tests after bts_model_adjst_ms_pwr 2015-09-22 16:41:32 +02:00
Alexander Chemeris 5becc4613a tests: Update busrsts_test build. 
We've added logging calls to the bursts processing. Add logging facility
initializatoin to the test code.

Alexander Chemeris b812839dfa trx: fix potential use of uninitialized toa variable. 
Not really a bug, as we're smart about it down the stream, but it's better to
be strict here as well.

Alexander Chemeris ae525a8761 trx: Send POWERON/OFF commands to osmo-bts only for the first channel. 
osmo-trx never supported separate power control for trx's, but now it started
to be more strict about it.

Alexander Chemeris 29ea40f538 trx: Assume 100% BER if total decoded bits is 0 in l1if_process_meas_res() 2015-09-22 16:41:31 +02:00
Alexander Chemeris e9abc5a4f3 trx: Cleanup unused parts of loops.c 2015-09-22 16:41:31 +02:00

Alexander Chemeris 68e8b2b1d5 trx: Fix typo in a log message. 2015-09-22 16:41:31 +02:00
Alexander Chemeris 391ff14977 trx: More logging for voice frame decoding functions. 2015-09-22 16:41:31 +02:00
Alexander Chemeris cf18dcd5fd tests: Update bursts_test to accommodate BER calculations. 2015-09-22 16:41:31 +02:00
Alexander Chemeris 6fceaca584 trx: Implement BER calculations. 
A known issue with this code is that BER is not updated for lost TCH frames,
because osmo-trx doesn't send any indication for them and we don't have
a callback to handle this.

Otherwise the code seem to work fine.

Thomas Tsou ddc0bf14d5 TRX: Remove extra TCH/HS puncturing value 
3GPP TS 05.03 "Channel coding" specifies the puncturing matrix (1,0,1)
for class 1 information bits and tail bits valued u(0) to u(103) for a
maximum puncturing index of 311. The puncturing index 313 exceeds the
maximum index and causes osmo_conv_get_output_length() to output the
improper length of 210 instead of 211.

Andreas Eversberg deb01a2652 TRX: Check if Transceiver indicates an out of range clock 
If frame number is out of range (>= 2715648), the scheduler's process
would end up in an infinite loop. This is because the loop would schedule
bursts until the indicated frame number is reached, which would not be
possible.

The openbts, calypso-bts and osmo-trx might send out out of range clock
indications every 3.5 hour.

Andreas Eversberg f39c739bd6 TRX: Activate LCHAN of CCCH when CCCH is configured on time slot 2015-09-22 16:41:30 +02:00
Andreas Eversberg f66f5b3ddc TRX: Free bust buffer memory to when changing lchan type 2015-09-22 16:41:30 +02:00
Andreas Eversberg c241afa87c TRX: Add VTY option to allow setting RTS advance in frames 
RTS (ready-to-send) must be issued in advance, so BTS core and especially
osmo-pcu can provide downlink data frames early enough. In some cases PCU
might provide frames too late, so they must be dropped. If PCU provides
frames too late, due to high system load, this "RTS advance" setting must
be increased.

Martin Hauke 178d618d5a TRX: fix some typos in comments 2015-09-22 16:41:30 +02:00
Martin Hauke c9ddb2ba22 build: Use AM_CPPFLAGS in Makefile.am 
Since automake 1.13 INCLUDES is depricated and causes a warning
Inspired from similar patches by Alexander Huemer for other osmocom
projects.

Martin Hauke 73d3f46994 tests: make tests for sysmobts conditional 2015-09-22 16:41:30 +02:00
Andreas Eversberg b2482a8574 Allow TRX 0..254 at VTY, even if less TRX are available 
Instead of limiting the number of TRX at VTY to the actual number of
supported TRX, VTY allows to configure any possible number of TRX. If a
TRX is configured, which is not supported by BTS model, an error message is
returned, which states that the given TRX is not supported.

Andreas Eversberg f0072a8de8 TRX: Do not send burst on IDLE channels at TRX != C0 
This is required, so the transceiver transmits no power.

Andreas Eversberg 8c8998e551 TRX: Set ciphering to an initial state when activating channel 
Handover and assignment may activate channels with ciphering already set,
so we need to tell scheduler to enable/disable ciphering and set the
correct cipher state.
