Hi All, I have enabled the bionic-proposed repo as described in link. OVS-master is used for testing, containing the build-time binutils bug check as described above.
1) Can confirm that old binutils version (2.30-21ubuntu1~18.04.3) had issue, and OVS was correctly DISabling AVX512. 2) Can confirm that with -proposed binutils (2.30-21ubuntu1~18.04.4), OVS build system is correctly ENabling AVX512 support, as linker checks are passing. After the configure step, I have tested OVS, running traffic and enabling the AVX512 optimizations. It is working as expected, with AVX512 instructions running in the datapath. I believe you have already added the "verification-done" and bionic versions Christian, so I'll not change the status... please let me know if I misunderstood the process. Thanks Robie & Christian for your support on this issue! -Harry -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1883880 Title: fix non-8-bit x86 displacements breaking AVX512 builds on Bionic To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/binutils/+bug/1883880/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
