Xavier Arteaga 8c3a0153b9 Added missing AVX512 intrinsics and flags. Fixes #291. 2018-11-21 18:09:09 +01:00
Andre Puschmann 0380c83175 remove RF device calibration settings from UE/eNB config 
- this remove RF calibration parameters that were an extra
  section in the eNB/UE config but were hardly used (only old bladeRF)
- a better way to pass those parameter would be through the
  device args in the normal rf config section

IgnasJ 67c8bf1368 Fixes for srsLTE on ARM (#229) 
* Fix ARM NEON code compilation

Fix LV_HAVE_NEON defintion incorrecly used instead of HAVE_NEON in some places
Replace vqabsq_s32 with vabsq_f32 as vqabsq_s32 requires int type (fails to compile)
Fix missing NEON code path in mat.h in srslte_mat_2x2_mmse_csi_simd()

* Fix timestamp overflow issue on 32-bit systems with Soapy driver

'time_t secs' can be 32-bit on some systems. This causes calculation:
'secs * 1000000000;' to overflow.
