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
