Hi guys, Intel has released a bunch of new microcodes the last days. As these are not released to the public, you might want to look again into https://forums.freebsd.org/threads/introducing-cpupdate-a-microcode-tool-for-freebsd.64588/ There you find how to obtain the microcodes in case your computer manufacturer hasn't supplied BIOS updates. I have updated the cpupdate tool, too. It does the automatic activation of the new CPU features for meltdown/spectre mitigation now, too. So you do no longer need devcpu-data/cpucontrol. If you tried devcpu-data/cpucontrol and wondered why it does not work, here is background: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=192487#c0 Have fun testing the new microcodes and FreeBSD's first mitigation patches! Stefan
