osmo-bts - Osmocom BTS-Side code (Abis, scheduling)

2016-12-01	Fix AGCH/PCH proportional allocation	Max	1	-0/+14
	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. Change-Id: I11377b12680ac3b2f77f80e742b6f0af63fc9c1e Related: OS#1575
2016-03-17	Fix SI2ter scheduling	Max	1	-2/+3
	According to 3GPP TS 05.02 § 6.3.1.3 SI2ter messages should be scheduled in FN with TC=4 only if SI2bis messages are also available.
2016-03-11	Fix copy-paste issue	Max	1	-1/+1
	This issue prevented scheduling of SI 2quater messages.
2014-05-22	common: Ignore "si.valid" outside of _MAX_SYSINFO_TYPE	Holger Hans Peter Freyther	1	-1/+1
	Limit the range from 0 to (_MAX_SYSINFO_TYPE - 1) instead of 0 to 31. This way we will never access the lchan->si.buf[] out of bounds. This is only a theoretical issue though as the code filling the lchan->si.buf for the SACCH will not have valid >= _MAX_SYSINFO_TYPE. Add a small regression test to check we still schedule all SIs. Fixes: CID 1040765
2014-05-22	common: Remove unused gsm_time parameter from lchan_sacch_get	Holger Hans Peter Freyther	1	-1/+1

2012-06-14	system information: avoid modulo 0 / SIGFPE	Harald Welte	1	-3/+8
	As Holger pointed out, it may well be the case that there are no system information messages to be sent at TC=4, and we should avoid a modulo by 0. I'm simply sending SI2 instead now, as it isn't forbidden to send it more often than the minimum at TC=2...
2012-06-03	sysinfo: Make our SI scheduling more complete	Harald Welte	1	-5/+80
	We now implement the fairly complex rules for schedulign of SI 2bis/2ter/2quater, 13 and 9 on TC=4 and TC=5 of the BCCH Norm. The patch is currently untested.
2012-06-02	sysinfo: Schedule SI 2bis and 2ter	Harald Welte	1	-4/+4
	In case we have neighbor cells in different bands, we should send those SI...
2011-06-29	remove debugging printf in sysinfo code	Harald Welte	1	-1/+0

2011-06-27	re-work original osmo-bts with support for sysmocom femtobts	Harald Welte	1	-0/+66
	This code re-works osmo-bts to add support for the upcoming sysmocom BTS. It also tries to add some level of abstraction between the generic part of a BTS (A-bis, RSL, OML, data structures, paging scheduling, BCCH/AGCH scheduling, etc.) and the actual hardware-specific bits. The hardware-specific bits are currently only implemented for the sysmocom femtobts, but should be (re-)added for osmocom-bb, as well as a virtual BTS for simulation purpose later. The sysmocom bts specific parts require hardware-specific header files which are (at least currently) not publicly distributed.
