I think its correct to drop it here. The code was ported from osmo-bts some years ago and I think this printf was left there as a placeholder for the code we now add with this patch. https://gerrit.osmocom.org/c/osmo-bsc/+/31497/comment/3e2cf751_41a20ed3 PS2, Line 794: for (i = 0; i < PCU_IF_NUM_TRX; i++) { > this is a fix of a magic number, very good but rather in a separate patch Done https://gerrit.osmocom.org/c/osmo-bsc/+/31497/comment/ae63d0a7_d4cd98bf PS2, Line 801: && ts->pchan_on_init == GSM_PCHAN_OSMO_DYN > Why does this apply only to dynamic timeslots?

Thats at least what it is tested for. It indeed has a list with BTSs, but it never ran with multiple BTSs. Also the PHY implementations pick only the first BTS in that list. As far as the BSC is concerned we can fix this. For the sock_accept and sock_close function we have to run over all BTSs in the network. When we get the primitive from the PCU it has the BTS number in it. I will fix this in a different patch since it is a bit out of scope here. I will also keep the llist_entry() to keep consistency with the existing code. https://gerrit.osmocom.org/c/osmo-bsc/+/31497/comment/62e097d6_ba76a0fe PS2, Line 973: gsm_bts_trx_num > agree Done https://gerrit.osmocom.org/c/osmo-bsc/+/31497/comment/8bad96dd_676f090a PS2, Line 976: 8 > could also use TRX_NR_TS, but ARRAY_SIZE is also my favorite; TRX_NR_TS is our legacy way, these day […] Done https://gerrit.osmocom.org/c/osmo-bsc/+/31497/comment/8001ce33_69ada64d PS2, Line 979: && ts->pchan_on_init == GSM_PCHAN_OSMO_DYN && ts->fi->state == TS_ST_UNUSED) { > Also for GSM_PCHAN_TCH_F_PDCH ?
