From b57051c35dd09e74d4f8857194524231a7224aeb Mon Sep 17 00:00:00 2001 From: John Papandriopoulos Date: Sun, 28 May 2017 19:24:59 -0700 Subject: [PATCH] spandsp: disable fixed point implementation On a Netgear R7000 (ARMv7) without floating point, using SpanDSP with fixed point to send/receive fax on Asterisk resulted in repeated failure and intermittent performance. Disabling fixed point fixed these issues; the software floating point implementation was fine for real-time use. Now on a Netgear R7800 (ARMv7) with hardware floating point, the autoconf auto-detect will say no floating point is available, and again enables the poor performing fixed point implementation.
