Как прогрузить микрокод (https://downloadmirror.intel.com/27591/eng/microcode-20180312.tgz) в CPU от Интел в ОС SLES11SP4?

2

обновить пакет kernel-firmware

3

В общем, если есть подписка, то можно скачать c сайта https://download.suse.com/patch/finder/ и установить пакет microcode_ctl-1.17-102.83.15.1.src.rpm.

rpm -Uhv microcode_ctl-1.17-102.83.15.1.src.rpm

reboot

Получаем:

Если подписки нет, то:

wget -P /tmp https://downloadmirror.intel.com/27591/eng/microcode-20180312.tgz

cd /tmp

mkdir firmware

cd firmware

tar xvf /tmp/microcode-20180312.tgz

cp -rv /tmp/firmware/microcode.dat /etc

cp -rv /tmp/firmware/intel-ucode/* /lib/firmware/intel-ucode/

microcode_ctl -u

mkinitrd

rebuild src rpm https://build.opensuse.org/package/show/openSUSE:Factory/ucode-intel

Ошибся немного, вместо пакета microcode_ctl-1.17-102.83.15.1.src.rpm, нужно установить пакет microcode_ctl-1.17-102.83.15.1.x86_64.rpm.

Подправил ниже, может кому пригодится:

Скачать c сайта https://download.suse.com/patch/finder/ и установить пакет microcode_ctl-1.17-102.83.15.1.x86_64.rpm.

rpm -Uhv microcode_ctl-1.17-102.83.15.1.x86_64.rpm

reboot
