2016-08-30Revert "LC15: Hardware changes:"sysmocom/lc15_old_firmwareNeels Hofmeyr17-296/+310
This reverts commit cbbce0be0965c3160c4916384c3d3d5303c57ae2. Needed for the litecell15 instance in our lab that still runs with older firmware. Change-Id: Ibcfe651e3793b433e6479bfb610765a468e699e6
2016-08-30Fix ip.access style dyn PDCH, broken in 37af36e85eca546595081246aec010fa7f6fd0beNeels Hofmeyr2-16/+38
Commit "sysmo,lc15: ts_connect_as(): log error also for pchan_as == TCH/F_PDCH" introduced a check for TCH/F_PDCH intended only for TCH/F_TCH/H_PDCH. It looked correct, but TCH/F_PDCH startup was designed differently: For TCH/F_PDCH, the idea was to look it up in pchan_to_logChComb[] and obtain the TCH/F channel combination, so that TCH/F_PDCH first initialize as TCH/F. So pchan was in fact intended to be passed as TCH/F_PDCH. For Osmocom TCH/F_TCH/H_PDCH, we've in the meantime added a ts_opstart() function that makes this decision explicitly. So, instead of reverting the erratic commit, add TCH/F_PDCH to ts_opstart(), for both sysmo and lc15. In ts_opstart(), move to a switch statement to resolve the actual pchan to use for ts_connect_as(). Drop TCH/F_PDCH and TCH/F_TCH/H_PDCH from pchan_to_logChComb[] and comment.

2016-08-30cosmetic: common ts_is_pdch()Neels Hofmeyr2-11/+16
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.

This reverts commit 53d792c3b027bfb42d77804e3e687a287e122ef3. See http://osmocom.org/issues/1796 The commit caused this error for PDCH TS 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 Plain PDCH TS show this error but continue to function despite the SAPI activation failure. As a side effect, the SAPI activation failure breaks dynamic TS.

Notice that lc15 still has PTCCH UL disabled all the while, before and after this commit and its revert. Also note that PTCCH DL is and has been enabled without problems (see further above in sapi_dir_pdtch_sapis[]). This is only about PTCCH UL.

2016-07-28trx: Enable EGPRS handling through burst lengthsTom Tsou5-71/+149
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.

2016-07-14osmo-bts-trx: init OML only once by sending AVSTATE_OK with OPSTATE_ENABLEDNeels Hofmeyr1-11/+1
When receiving an OPSTART for the BTS object, also set the availability state to OK. Before, the availability would remain at NM_AVSTATE_DEPENDENCY, which caused an unfortunate chain reaction resulting in osmo-bts-trx going through the initialization sequence twice: BTS BSC |<-----| SITE_MANAGER OPSTART n |----->| BTS state change: OPSTATE_DISABLED, AVSTATE_DEPENDENCY o | | This signals to nm_statechg_event() in bts_ipaccess_nanobts.c r | | to (a) Set BTS Attributes and (b) send BTS OPSTART m |<-----| Set BTS Attributes (a) a | | When osmo-bts-trx receives a Set BTS Attributes, it sends l |----->| CHANNEL state change: OPSTATE_DISABLED x8 | | This signals the BSC to Set CHANNEL Attributes and OPSTART i |<-----| Set CHANNEL Attributes x8 n |<-----| CHANNEL OPSTART x8 i |----->| CHANNEL state change: OPSTATE_ENABLED, AVSTATE_OK x8 t | | |<-----| BTS OPSTART (b) | | osmo-bts-trx immediately replies with: |----->| BTS state change: OPSTATE_ENABLED, AVSTATE_DEPENDENCY | | Unfortunately, availability is left at DEPENDENCY, | | and the NM_OC_BTS case in nm_statechg_event() only | | checks for availability, not for the opstate. | | Hence nm_statechg_event() again feels inclined to | | to (a) Set BTS Attributes and (b) send BTS OPSTART, | | --+------+----- This is where the second round starts | | s |<-----| Set BTS Attributes (a) e | | When osmo-bts-trx receives a Set BTS Attributes, it sends c |----->| CHANNEL state change: OPSTATE_DISABLED x8 o | | All channels are disabled again, and then re-launched: n |<-----| Set CHANNEL Attributes x8 d |<-----| CHANNEL OPSTART x8 |----->| CHANNEL state change: OPSTATE_ENABLED, AVSTATE_OK x8 | | i |<-----| BTS OPSTART (b) n | | osmo-bts-trx again sets the OPSTATE_ENABLED, but since i | | this time it was already enabled, no further state change t | | is sent back to the BSC. This nightmare pivots on two hinges: 1. osmo-bts-trx fails to set BTS availability to AVSTATE_OK. 2. nm_statechg_event() fails to heed the OPSTATE_ENABLED of the BTS state change. Note, the configured channels from the first round were not actually taken down, only the OML OPSTATE_DISABLED were sent. In this commit, fix the osmo-bts-trx side: send AVSTATE_OK for the BTS object upon sending OPSTATE_ENABLED, so that only the part marked "normal init" above is run. This change applies the same fix to other OML objects, which should make sense in the same manner, within the current hackish OML implementation: * NM_OC_BTS * NM_OC_SITE_MANAGER * NM_OC_BASEB_TRANSC * NM_OC_GPRS_NSE * NM_OC_GPRS_CELL * NM_OC_GPRS_NSVC This means that the NM_OC_CHANNEL case just above is identical, and thus collapse NM_OC_CHANNEL onto the other cases. Drop the comments from NM_OC_CHANNEL since they merely rephrase the commands themselves. See OS#1770 for BTS and NITB logs. Fixes: OS#1770 Change-Id: I08aa861f6100568c79750f4fbc9a32e1557b9304

Many erratic PDTCH blocks are expected. To not bloat the log, notifications for this should be on debug level.
