TST/Hack: Disable all atomic BPF tests
Browse files Browse the repository at this point in the history 
As most of them fail miserably on QEMU. For example:

archs-lnx# mount -t debugfs debugfs /sys/kernel/debug
archs-lnx# sysctl net.core.bpf_jit_enable
           net.core.bpf_jit_enable=0
archs-lnx# insmod test_bpf.ko test_id=327

qemu-system-arc: /src/qemu/target/arc/op_helper.c:185:
  helper_llockd: Assertion `(addr & 0x7) == 0' failed.

This is the BPF interpreter causing the assert, because none of the
atomic tests are supported by JIT (yet). I didn't observe this amount
of failures 6 months ago, but back then I was using an older
toolchain. This behaviour is observed when using 2023.03 toolchain.

The issue is submitted at:
