We fully support microcode updates (as does FreeBSD).
pkg install devcpu-data
cpucontrol -u /dev/cpuctl0
cpucontrol -u /dev/cpuctl1
... (iterate all cpus)
If you download a microcode update that isn't yet in the devcpu-data
package, you will wind up with a microcode.dat file from Intel which you
have to break up using a tool that is in devcpu-data's build directory.
use the ./ucode-tool binary. Urm. I think something like:
./ucode-tool -i <location_of_intel_microcode_dat_file>
and then move all the *.fw files to /usr/local/share/cpucontrol
Then cpucontrol -u can find them.
You need the latest master (the cpuctl device needed a larger buffer to
handle newer cpu's larger microcodes).
