[PATCH 0/4] core/conv: Fast Viterbi decoding

by Thomas Tsou

Hi all, This patch set adds to libosmocore an optimized Viterbi decodeer for architecture specific (Intel SSE) and non-specific cases. The implementation covers codes with constraint lengths of K=5 and K=7 and rates 1/4 to 3/4, which make up the majority of GSM use cases. Speedup from the current implementation is in the range of 5 to 20 depending on the processor and code type. API is unchanged. Tested on Haswell (i7-4770K) and Atom (D2550). Additional test codes from osmo-bts are included. Further tests for AWGN bit-error-rate and benchmarks can be found in the following repository. https://github.com/ttsou/osmo-conv-test Here are some examples. Bit error test for GPRS CS2 with SNR of 5 dB and 100000 bursts. $ ./conv_test -c 2 -e -r 5 -i 100000 ================================================= [+] Testing: GPRS CS2 [.] Specs: (N=2, K=5, non-recursive, flushed, not punctured) [.] Input length : ret = 290 exp = 290 -> OK [.] Output length : ret = 588 exp = 588 -> OK [.] BER tests: [..] Testing base: [..] Input BER.......................... 0.042443 [..] Output BER......................... 0.000006 [..] Output FER......................... 0.001350 (135) [..] Testing SIMD: [..] Input BER.......................... 0.042460 [..] Output BER......................... 0.000005 [..] Output FER......................... 0.001240 (124) Timed AFS benchmark with 8 threads and 100000 bursts per thread. $ ./conv_test -b -c 10 -j 8 -i 100000 ================================================= [+] Testing: GSM TCH/AFS 6.7 [.] Specs: (N=4, K=5, recursive, flushed, punctured) [.] Input length : ret = 140 exp = 140 -> OK [.] Output length : ret = 448 exp = 448 -> OK [.] Performance benchmark: [..] Encoding / Decoding 800000 bursts on 8 thread(s): [..] Testing base: [..] Elapsed time....................... 4.320001 secs [..] Rate............................... 25.925920 Mbps [..] Testing SIMD: [..] Elapsed time....................... 0.458272 secs [..] Rate............................... 244.396341 Mbps [..] Speedup............................ 9.426718 -TT

recurring issue with OpenBSC

by Ciaby

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 Hi! First a small update: we finally decided to _not_ use token mode, as it confuses a lot of phones, after receiving the token message the SIM goes into an error state and the only way to recover is to reboot the phone. Now we just read the IMSI straight from the SIM (using the card python library, just like osmo-sim-auth does) and register them. Now, the issue we see is that 1-2 users every day reach a point where they can make phone calls and send messages, but they can't receive neither of them. Sometimes the problem can be fixed by running: > subscriber extension <EXT> clear-requests but this only work when there are pending requests. In other cases, the phone has to be rebooted. Did anyone encounter the same issue?

Final review of L1SAP ported to current maste

by Harald Welte

Dear all, the valuable L1SAP abstraction has been sitting out of master for too long time. It is a pity that this has taken so long. I've finally been able to put some time into osmo-bts again and reviewed the following patch series. It consists of mostly Andreas' work, interspersed with smaller patches/fixups that I introduced after the respective original patch from Andreas. I have started a sysmobts between all of the major steps in this patch series and did a short manual tests involving registration (LU) of two MS, mobile-to-mobile call and vty-to-mobile SMS. So far I couldn't see any problems. What has not been tested yet is the PCU interface as well as encryption support. I plan to do this later this week. I intend to merge the code after this current review cycle. Please take your time to have a look and provide feedback (if any), so we can get this over and work on new features again, rather than infrastrutural changes. I didn't yet rebase the osmo-bts-trx interface on top of the L1SAP, as I don't have a hardware setup for it, and I will leave it to the owners of such hardware to publish/push the respective code after L1SAP is merged.

handover crash

by Holger Hans Peter Freyther

hi, this is a note. We had a crash with handover. So ho->new_lchan points to a "valid" lchan but ho->new_lchan->conn is NULL. Which means the new lchan failed/was freed/re-used.. but the "ho" entry wasn't killed. I thought I fixed such a bug recently but obviously no. Program terminated with signal 11, Segmentation fault. #0 0x00000000004078a7 in ho_T3103_cb (_ho=<optimized out>) at handover_logic.c:192 192 ho->new_lchan->conn->ho_lchan = NULL; (gdb) p

[PATCH] ipa: Set the BSC_FD_WRITE in ipa_client_conn_open

by Holger Hans Peter Freyther

From: Holger Hans Peter Freyther <holger(a)moiji-mobile.com> When the link is being created BSC_FD_WRITE and BSC_FD_READ are being ored into the flag. When the socket connects the first time the ipa_client_fd_cb function is called and the link->state is moved from connecting to connect. In case the connection drops and ipa_client_conn_open is called again the BSC_FD_WRITE flag might not be set. This means that after the socket is connected, ipa_client_fd_cb will not be called. This means that the updown_cb will not be called until after the first write or read on the socket. It might even lead to missing some data. When re-connecting set the write flag again. --- src/input/ipa.c | 1 + 1 file changed, 1 insertion(+) diff --git a/src/input/ipa.c b/src/input/ipa.c index e2da6f4..1ddf802 100644 --- a/src/input/ipa.c +++ b/src/input/ipa.c @@ -218,6 +218,7 @@ int ipa_client_conn_open(struct ipa_client_conn *link) return ret; } link->ofd->fd = ret; + link->ofd->when |= BSC_FD_WRITE; if (osmo_fd_register(link->ofd) < 0) { close(ret); link->ofd->fd = -1; -- 2.1.3

[PATCH 1/2] logging: Make it possible to print category/subsys and timestamps

by Holger Hans Peter Freyther

From: Holger Hans Peter Freyther <holger(a)moiji-mobile.com> We want to see from which category/subsystem a certain log message is coming from and use a different timestamp format as well. Add two new bitfields. This doesn't change the size of the structure and on 32bit we still have 27bits left. The extended timestamp will take preference over the current and default timestamp format.

how add multi-trx support to osmo-bts

by ehsan akhavan

Hello I know that OpenBSC support multi-trx BTS,but osmo-bts doesn't. So how i can enable this ability in osmo-bts? I see the source code and i think i should change some structures and add trx_id variable to them. but i don't know the correct way. can anyone help me?
