make test produces 8 failures pdcch_test

[Wingqvist]

Issue Description

I followed the guide to build srsRAN. When I run make test I get 8 errors regarding pdcch_test

Setup Details

I have a fresh install of Ubuntu 21.10, running on legacy hardware. Specifically I use the Intel i7 2600k.

Expected Behavior

all tests should pass

Actual Behaviour

99% tests passed, 12 tests failed out of 1463

Label Time Summary: chest = 31.44 secproc (22 tests) fec = 0.60 secproc (11 tests) ldpc = 0.01 secproc (1 test) lib = 270.50 secproc (1005 tests) lte = 244.56 secproc (942 tests) nr = 133.15 secproc (280 tests) pdcp = 0.36 secproc (3 tests) phch = 55.99 secproc (485 tests) phy = 253.55 secproc (1004 tests) polar = 0.00 secproc (1 test) rlc = 26.49 secproc (11 tests) srsenb = 8.79 secproc (10 tests) srsue = 1.12 secproc (3 tests) turbo = 0.59 secproc (9 tests)

Steps to reproduce the problem

Install everything using the guide and run the make test command

Additional Information

I read in another post that there might be some issues related to older cpu architectures that are missing more recent instruction sets, which I think the 2600 do. If so, I would be happy to get this confirmed and some guidance on the implications of running this even with the failed tests. Would it be stable?

Thanks for the report. I agree we should not fail here. But I guess it's because you're using a very old CPU without AVX2 support. Some of the DSP code requires AVX2.
