This is an automated email from the git hooks/post-receive script. It was
generated because a ref change was pushed to the repository containing
the project "Osmocom BTS-side code (Abis, scheduling, ...)".
The branch, neels/dyn_fixes has been updated

This update added new revisions after undoing existing revisions. That is
to say, the old revision is not a strict subset of the new revision. This
situation occurs when you --force push a change and generate a repository
containing something like this:
* -- * -- B -- O -- O -- O (38ad25b1b01e765d85ee586cc5bf15135ec9a0a5)
\
N -- N -- N (42b8a25b0bd8eb53a79841fe463742a4aa259b02)
When this happens we assume that you've already had alert emails for all
of the O revisions, and so we here report only the revisions in the N
branch from the common base, B.
Those revisions listed above that are new to this repository have
not appeared on any other notification email; so we list those
revisions in full, below.

commit 42b8a25b0bd8eb53a79841fe463742a4aa259b02

dyn TS: sysmo,lc15: ph_data_req: fix PDCH mode detection
Though this patch theoretically makes a lot of sense, it is not entirely clear
why dyn TS are working without it. Committing due to common sense, not to fix
any actual breakage.

cosmetic: common ts_is_pdch()
Have one common ts_is_pdch(), placed in lchan.c, since this file is pretty
empty and pretty close to ts. Publish in gsm_data.h.
Remove the if-style implementation from l1sap.c, and instead implement in a
switch statement.
This prepares for upcoming ts_is_pdch() usage in ph_data_req() for sysmo and
lc15.

dyn TS: measurement: use correct nr of subslots, rm code dup
In measurement.c, fix the number of sublots for TCH/F_TCH/H_PDCH, by using
ts_subslots() from gsm_data_shared.c. The local dup of subslots_per_pchan[] is
no longer needed. (depends on recent commit to openbsc.git for ts_sublots())

dyn TS: complete for TRX
Apply similar fixes as for TCH/F_PDCH also for TCH/F_TCH/H_PDCH:
Detect dyn TS in PDCH mode in ts_is_pdch().
In trx_set_ts(), enhance the "if (TCH_F_PDCH)" to a switch statement
including
both dynamic channel types. Adjust the comment to include both kinds.

sysmo: fix dyn TS: Revert "Activate PTCCH UL" [in sysmobts]
This reverts commit 53d792c3b027bfb42d77804e3e687a287e122ef3.
The commit caused this error with SysmoBTS:
DL1P <0007> l1_if.c:164 Tx L1 prim MPH-ACTIVATE.req
DL1C <0006> oml.c:811 Error activating L1 SAPI PTCCH on TS 7: Invalid parameter
DL1C <0006> oml.c:1089 (bts=0,trx=0,ts=7,ss=0) act failed mark broken due
status: -4
Since dynamic timeslots wait for the activation to succeed, the broken status
breaks dynamic timeslots on SysmoBTS. Initially GPRS works, but the state in
the BSC is messed up and placing calls fails for dyn TS:
DRLL <0000> chan_alloc.c:355 Failed to allocate TCH_H channel
DRSL <0004> abis_rsl.c:1656 BTS 0 CHAN RQD: no resources for TCH_H 0x45
Normal PDCH on SysmoBTS was not broken -- the error message occurs, but that
doesn't seem to matter much. Plain GPRS still works since there is no
switchover involved. But I can see no benefit in enabling PTCCH UL on sysmo.
Since the commit only enabled PTCCH UL in sysmobts, no other BTS models are
affected. Notice that lc15 still has PTCCH UL disabled all the while, before
and after this commit and its revert.
