2021-11-10add time_cc API: cumlative counter for time, reported as rate_ctrNeels Hofmeyr10-0/+1508
This is a candidate for adding to libosmocore (as osmo_time_cc), but let's first use this in osmo-bsc to make sure that it works as intended. I started out expecting to be done with this in half an hour, but I found out that accumulating elapsed time to an integer counter has a staggering amount of complexity to it, and a million pitfalls. The intended use is to report allAvailableSDCCHAllocated and allAvailableTCHAllocated performance indicators in OsmoBSC. Hopefully this will also be generally useful elsewhere, to be worth the effort. Related: SYS#4878 Change-Id: Icdd36f27cb54b2e1b940c9e6404ba9dd3692a310
2021-11-10refactor lchan countingNeels Hofmeyr10-72/+238
Add chan_counts_for_trx() and chan_counts_for_bts(). Drop bts_count_free_ts() and trx_count_free_ts(). Rationale: The bts_count_free_ts() and trx_count_free_ts() always returned the number of free lchans, not timeslots. Hence, passing the pchan type as argument never really matched the semantics. Especially, when looking for free SDCCH, there is no clear match on a gsm_phys_chan_config enum value: SDCCH8_SACCH8C, CCCH_SDCCH4, CCCH_SDCCH4_CBCH, SDCCH8_SACCH8C_CBCH? -- GSM_LCHAN_SDCCH is clear. ==> Rather count free lchans by enum gsm_chan_t. Counting lchans of distinct types required separate iterations for each lchan type. ==> Rather compose an array of counts for all types, in one go. I need to count the amount of free SDCCH lchans in an upcoming patch to implement the performance indicator allAvailableAllocatedSDCCH (cumulate time for which no SDCCH are available). To implement allAvailableAllocated{SDCCH,TCH}, I need a count of both the used as well as the total lchans for a type: it does not make sense to flag "all available allocated" if none are ever available. To properly count dynamic ts, I need the maximum total that can be possible at any time. And to count currently free lchans, I need the current total. This may seem counter intuitive, but consider, e.g.: - Obviously, if a cell has only static TCH/F timeslots, it does not make sense to flag that all available TCH/H are occupied, because no TCH/H are available ever. Just stating this as contrast to dyn TS. - If a cell has OSMO_DYN timeslots, I *do* want to flag that all TCH/H are occupied when all dyn timeslots are fully occupied. - If those OSMO_DYN however are all used as TCH/F, the current total of TCH/H becomes zero, and it seems like TCH/H should not be considered. - To count the nr of currently free lchans, I need the currently possible total of lchans and the nr of occupied lchans. So return both a maximum total and a current total of lchans. In above example, the maximum total shows that there would be TCH/H possible. BTW, it would be nice to keep a chan_counts array on trx, bts and bsc level and update as channels are allocated and released, instead of counting them all over periodically. But it's less error prone this way. Related: SYS#4878 Change-Id: I2fb48c549186db812b1e9d6b735a92e80f27b8d3

nanoBTS would NACK a CHANnel ACTIVation message for an 'intra cell channel change' if it does not contain the Timing Advance IE.

VAMOS secondary lchans are to be used specifically when the osmocom dyn TS is set to pchan_is=TCH_{F,H}. Setting secondary subslots for OSMO_DYN TS is not needed since it's only used to initialize the TS, and OSMO DYN already initializes 8 subslots (subslots_per_pchan[GSM_PCHAN_OSMO_DYN]=8). Otherwise, ts_setup_lchans() will try to initialize 8+2 lchans on the TS, which is more than needed and will access out of bounds in the array.
