[PATCH] libosmocore[master]: Add helper functions for AMR codec
by Max 31 May '16

31 May '16

Review at https://gerrit.osmocom.org/118 Add helper functions for AMR codec * add functions to encode/decode various codec paramters from RTP payload with AMR frame according to RFC 4867 * those functions are extended version based on code from osmo-bts' amr.c by Andreas Eversberg * add corresponding enum types and strings for logging * add regression tests It's useful both to replace manual parsing in osmo-bts with fuctions covered by test suite and as a debugging helpers for issues related to AMR.

libosmocore: patch for big-endian architectures
by Ruben Undheim 31 May '16

31 May '16

Hi, One test case fails for openbsc on big-endian architectures. This was traced back to struct erros in libosmocore. Please see patch below: commit fb3d353ab238a2d14cb8e9704995f14a2acd6c1b Author: Ruben Undheim <ruben.undheim(a)gmail.com> Date: Mon Dec 7 19:34:28 2015 +0100 Patched structs for big-endian architectures diff --git a/include/osmocom/gsm/protocol/gsm_04_08.h b/include/osmocom/gsm/protocol/gsm_04_08.h index 4800b48..0c2fcf2 100644 --- a/include/osmocom/gsm/protocol/gsm_04_08.h +++ b/include/osmocom/gsm/protocol/gsm_04_08.h @@ -4,6 +4,8 @@ #include <stdbool.h> #include <osmocom/core/utils.h> +#include <osmocom/core/endian.h> + /* GSM TS 04.08 definitions */ struct gsm_lchan; @@ -42,6 +44,7 @@ struct gsm48_classmark2 { } __attribute__ ((packed)); /* Chapter 10.5.2.1b.3 */ +#if OSMO_IS_LITTLE_ENDIAN == 1 struct gsm48_range_1024 { uint8_t w1_hi:2, f0:1, @@ -75,8 +78,44 @@ struct gsm48_range_1024 { uint8_t w16:6, w15_lo:2; } __attribute__ ((packed)); +#else +struct gsm48_range_1024 { + uint8_t form_id:5, + f0:1, + w1_hi:2; + uint8_t w1_lo; + uint8_t w2_hi; + uint8_t w2_lo:1, + w3_hi:7; + uint8_t w3_lo:2, + w4_hi:6; + uint8_t w4_lo:2, + w5_hi:6; + uint8_t w5_lo:2, + w6_hi:6; + uint8_t w6_lo:2, + w7_hi:6; + uint8_t w7_lo:2, + w8_hi:6; + uint8_t w8_lo:1, + w9:7; + uint8_t w10:7, + w11_hi:1; + uint8_t w11_lo:6, + w12_hi:2; + uint8_t w12_lo:5, + w13_hi:3; + uint8_t w13_lo:4, + w14_hi:4; + uint8_t w14_lo:3, + w15_hi:5; + uint8_t w15_lo:2, + w16:6; +} __attribute__ ((packed)); +#endif /* Chapter 10.5.2.1b.4 */ +#if OSMO_IS_LITTLE_ENDIAN == 1 struct gsm48_range_512 { uint8_t orig_arfcn_hi:1, form_id:7; @@ -110,8 +149,44 @@ struct gsm48_range_512 { uint8_t w17:5, w16_lo:3; } __attribute__ ((packed)); +#else +struct gsm48_range_512 { + uint8_t form_id:7, + orig_arfcn_hi:1; + uint8_t orig_arfcn_mid; + uint8_t orig_arfcn_lo:1, + w1_hi:7; + uint8_t w1_lo:2, + w2_hi:6; + uint8_t w2_lo:2, + w3_hi:6; + uint8_t w3_lo:2, + w4_hi:6; + uint8_t w4_lo:1, + w5:7; + uint8_t w6:7, + w7_hi:1; + uint8_t w7_lo:6, + w8_hi:2; + uint8_t w8_lo:4, + w9_hi:4; + uint8_t w9_lo:2, + w10:6; + uint8_t w11:6, + w12_hi:2; + uint8_t w12_lo:4, + w13_hi:4; + uint8_t w13_lo:2, + w14:6; + uint8_t w15:6, + w16_hi:2; + uint8_t w16_lo:3, + w17:5; +} __attribute__ ((packed)); +#endif /* Chapter 10.5.2.1b.5 */ +#if OSMO_IS_LITTLE_ENDIAN == 1 struct gsm48_range_256 { uint8_t orig_arfcn_hi:1, form_id:7; @@ -151,8 +226,50 @@ struct gsm48_range_256 { w21:4, w20_lo:3; } __attribute__ ((packed)); +#else +struct gsm48_range_256 { + uint8_t form_id:7, + orig_arfcn_hi:1; + uint8_t orig_arfcn_mid; + uint8_t orig_arfcn_lo:1, + w1_hi:7; + uint8_t w1_lo:1, + w2:7; + uint8_t w3:7, + w4_hi:1; + uint8_t w4_lo:5, + w5_hi:3; + uint8_t w5_lo:3, + w6_hi:5; + uint8_t w6_lo:1, + w7:6, + w8_hi:1; + uint8_t w8_lo:4, + w9_hi:4; + uint8_t w9_lo:1, + w10:5, + w11_hi:2; + uint8_t w11_lo:3, + w12:5; + uint8_t w13:5, + w14_hi:3; + uint8_t w14_lo:2, + w15:5, + w16_hi:1; + uint8_t w16_lo:3, + w17:4, + w18_hi:1; + uint8_t w18_lo:3, + w19:4, + w20_hi:1; + uint8_t w20_lo:3, + w21:4, + spare:1; +} __attribute__ ((packed)); +#endif /* Chapter 10.5.2.1b.6 */ +#if OSMO_IS_LITTLE_ENDIAN == 1 struct gsm48_range_128 { uint8_t orig_arfcn_hi:1, form_id:7; @@ -194,6 +311,49 @@ struct gsm48_range_128 { w27:3, w26_lo:1; } __attribute__ ((packed)); +#else +struct gsm48_range_128 { + uint8_t form_id:7, + orig_arfcn_hi:1; + uint8_t orig_arfcn_mid; + uint8_t orig_arfcn_lo:1, + w1:7; + uint8_t w2:6, + w3_hi:2; + uint8_t w3_lo:4, + w4_hi:4; + uint8_t w4_lo:1, + w5:5, + w6_hi:2; + uint8_t w6_lo:3, + w7:5; + uint8_t w8:4, + w9:4; + uint8_t w10:4, + w11:4; + uint8_t w12:4, + w13:4; + uint8_t w14:4, + w15:4; + uint8_t w16:3, + w17:3, + w18_hi:2; + uint8_t w18_lo:1, + w19:3, + w20:3, + w21_hi:1; + uint8_t w21_lo:2, + w22:3, + w23:3; + uint8_t w24:3, + w25:3, + w26_hi:2; + uint8_t w26_lo:1, + w27:3, + w28:3, + spare:1; +} __attribute__ ((packed)); +#endif /* Chapter 10.5.2.1b.7 */ struct gsm48_var_bit { I tried 30 seconds to figure out how to use Gerrit, but I couldn't figure out how to login, so I rather just post here.
