lchan_meas_check_compute() is a static function measurement.c.
In order to distribute the measurement result calculation events,
we need to be able to call lchan_meas_check_compute() from l1sap.c

add support for the TX/RX antenna-id feature that has been
introduced with release OCTSDR-2G-02.07.00-B1314-BETA. The
user can now set individual ID numbers for the TX and for
the RX antenna.

In case a system has a high-gain external PA (like a 40dB PA) connected
externally, we cannot simply switch the transceiver to 0 dBm in
trx_init() only to then start the ramping at much lower levels once the
PHJ completes in trx_init_compl_cb(). The result would be a short
0 + 40 dBm spike followed by later ramping. We want to avoid that
spike, particularly its associated inrush current, so let's bring up the
board with smething very conservative like -50 dBm, and then ramp from
there.

The macro L1SAP_IS_PTCCH(fn) only detects a PTCCH channel at fn%52 = 12,
the detection logic has been extended in order to detect PTCCH at fn%52 = 38.

The ra parameter indicates the reason for the received rach
request. osmo-bts uses the ra parameter to determine if the
received rach request is packet access related. If yes,
osmo-bts will forward the request to the PCU.
In order to determine if the ra is packet related or not,
the higher 4 bits must be equel to 0x7 and at least one of
the lower 4 bits must be zero.
The current method lacks checking of the lower 4 bits. It
would also accept 0b01111111, which is reserved for future
use. This commit extends the check to take also the last
4 bits into accound.

channel (TRX1) of osmo-trx
Move rxgain and tx-attenuation (power) parameters from phy_link layer to phy_inst layer.
Rxgain and tx-attenuation parameters should be set for each phy_inst and send for each osmo-trx channel accordingly via control commands.

It seems more user friendly to look at a calibration table in terms of
the delta (positive or negative) compared to the nominal gain value,
rather than a collection of absolute gain values. It has the added
benefit that the (API/data model) user doesn't have to specify a gain
value for each ARFCN, but rather can rely on the default nominal gain in
absence of a calibration table for this specific unit.

Currently the IP address where the control interface is bound
to is hardcoded to 127.0.0.1. This leads to problems with
multiple instances on one and the same machine. This commit
integrates the ctrl interface bind option into the VTY, so
that we can bind the ctrl interface to any IP address, just
like we do it with the VTY already.

* Unlike in AMR FR, in AMR HR incoming ONSET have to be treated
differently depending on whether we've recently sent SID UPDATE or
EMPTY frame. Split ST_SID_U FSM state into 2 states to accommodate for
that and make sure that additional states specific to AMR HR are not
used for AMR FR.
* Avoid sending E_VOICE and E_SID_U in corresponding states
as those do not initiate FSM state transitions anyway. This decrease
extra load from FSM signalling which otherwise would be triggered on
per-frame basis.
* Introduce separate signal for SID First P1 -> P2 transition to avoid
confusion with E_COMPL and E_SID_U initiated transitions from P1
state.
* Don't init DTX FSM for SDCCH channels.

Do not assume that 1 == BS_AG_BLKS_RES but take that information from
SI3. Note: due to current implementation quirks we activate channels
before SI3 obtained, than we deactivate channels upon receiving SI3 and
activate them again. This might not be necessary once we migrate to
proper OML state machines.
This affects lc15 and sysmo hw.

Add explicit state for recursion (sending the different payload data in
response to the RTS request for same FN) and corresponding
transition. Remove ST_FACCH_V as with new explicit recursion handling it
becomes unreacheable. This makes it easier to maintain
preemption (interruption of current procedure due to FACCH or
Inhibition). This also reduces the number of possible transitions out of
each state thus reducing graph's cyclomatic complexity.

Handle ONSET cause by Voice and FACCH separately. In case of Voice we
have RTP payload which we have to cache and send later on in next
response to L1 RTS. FACCH have higher priority so it preempts both voice
and silence alike - hence we can send ONSET immediately but still have
to track previous state in order to get back to it gracefully.
This affects lc15 and sysmo hw as there's no FSM-based DTX
implementation for other models yet.
Note: this requires patch for OpenBSC which adds FACCH buffer to tch.dtx
struct.

Use dedicated FSM to handle all DTX DL related events:
- add explicit checks if DTX DL is enabled (fixes regression for non-DTX
setup introduced in 654175f33bd412671e3ef8cdd65c0689d10f278c)

- sync with corresponding changes in OpenBSC's
- handle FACCH-related DTX ONSET events

Move code from tch.c (lc15, sysmo) into generic function which:

- cache SID if necessary or invalidate cache

Previously SID retransmission was scheduled incorrectly based on GSM
frames instead of voice frames. Fix this by using GSM Fn only as elapsed

* compute estimation for elapsed time since last retransmission using

This reverts commit 06968beab90806cba94c8b331276e4dc209c152b.
Theoretically, this patch makes a lot of sense, but in order to be able to
build osmo-bts-octphy until the headers version is clarified, revert use of
usCentreArfcn:
Above commit uses an usCentreArfcn member that is never defined in the history
of our octphy-2g-headers.git. This usCentreArfcn does exist in a code snapshot
OCTSDR-2G-02.05.00-B780-DEBUG, which is not (yet?) publicly available.
Also, the current headers version is apparently 02.07, though the octasic
version numbers have been known to cause confusion among osmocom folks.
This along with one other revert fixes this build problem:

Prepare for a dyn TS patch that needs to call rsl_tx_chan_act_ack() directly
without the rel_act_kind decision.
Add function rsl_tx_chan_act_acknack() to wrap rsl_tx_chan_act_ack() and
rsl_tx_chan_act_nack(). Move the decision whether to drop the ack/nack, based
on lchan->rel_act_kind, to the new function, losing some code dup.
Change all callers to use the new function; drop the two older ones from rsl.h
and make them static.
Note: for nack, the exception for dyn TS in PDCH mode was missing
(rsl_tx_chan_act_nack() had only the rel_act_kind != LCHAN_REL_ACT_RSL
condition, but should also have had the dyn TS exception as in
rsl_tx_chan_act_ack()). I already know that this exception will again be
removed in an upcoming commit, but for patch readability it logically makes
sense to add it here. To easily include the nack case, drop the check for which
pchan the dyn TS is operating as, because a rel_act_kind == LCHAN_REL_ACT_PCU
implies that it is either already in or trying to become PDCH mode.

Existing interfaces are coded with the implicit expectation of using
a burst sequence length of 148, which is constant with GSM and GPRS.
That changes with EGPRS, where the burst length may be 444 due to
the use of 8-PSK instead of GMSK modulation.
Setup the interface to accept and return a length value with the
burst sequence. This allows 444 length bit vectors to/from the
EGPRS decoder/encoder. Length is explicitly used as a identifier for
8-PSK vs. GMSK modulated sequences.

lchan_lookup in openbsc abis_rsl.c and rsl_lchan_lookup() rsl.c are the
same code, except for the log context, which is only set in abis_rsl.c.
The common code was factored out to gsm_data_shared.c in openbsc.git.
Use the *rc return code argument to keep the logging part in the newly

dup for logging
The rsl_lchan_lookup() implementation is removed from osmo-bts, so a recent

Move the actual switch from static conf_lchans_for_pchan() into new 'public'
function conf_lchans_as_pchan(), adding an explicit pchan argument. This allows
passing a non-trivial pchan, for dynamic TS.
conf_lchans_as_pchan() now takes a pchan argument, so distinguish the naming

We're about to introduce a new kind of dynamic channel, which will also use
parts of the ip.access mode dyn PDCH code paths. Make sure the general parts
have general names and mark ip.access specific parts as such.
Rename dyn_pdch_ts_[dis]connected() to cb_ts_[dis]connected().
Rename dyn_pdch_complete to ipacc_dyn_pdch_complete().
From cb_ts_[dis]connected(), factor out the current code into static
functions ipacc_dyn_pdch_[dis]connected() -- this will make sense once the
new dynamic kind is added to cb_ts_[dis]connected().
