Re: Building gnuradio and hooking into neonv8
You should be okay. Your cmake is selecting: -- Available architectures: generic;neon;neonv8;norc -- Available machines: generic;neon;neonv8 So you'll get 32-bit neon (and a couple of 32-bit neonv8) kernels. You won't get the assembly language enhancements to some kernels since those are only available for armv7. Ron On 5/30/20 05:40, Ron Economos wrote: My bad, that toolchain file is for 32-bit armv8. You're correct that those flags are already enabled on 64-bit. However, I'm not sure if volk actually supports 64-bit armv8. I'll have to take a look at it. Or maybe someone else can comment.

Building gnuradio and hooking into neonv8
Hi, I am trying to build gnuradio 3.8.10 on a raspberry pi 4 under 64 bit ubuntu server. I am unconvinced from the cmake output that it is going to plan. I know I could cross-compile, I’ll do that later. Environment:gcc (Ubuntu/Linaro 7.5.0-3ubuntu1~18.04) 7.5.0Linux raspberry 5.3.0-1026-raspi2 #28~18.04.1-Ubuntu SMP Thu May 21 14:48:58 UTC 2020 aarch64 aarch64 aarch64 GNU/Linux What I don’t understand is whether the code (volk) will be built to hook into neon properly. The thing that is irking me in cmake’s output is: -- CPU is armv8, Overruled arch neonv7 What does this mean? The full cmake output is listed below. I’d be very grateful if someone can tell me if this is good or bad.
