Please contact your system vendor for a BIOS/firmware update that contains
|

the latest microcode version. For the information regarding microcode versions

required for mitigating specific side-channel cache attacks, please refer

to the following knowledge base articles:

The information regarding enforcing microcode update is provided below.
|
||||
|
||||
To enforce usage of the latest microcode revision for a specific kernel
|
||||
version, please create a file "force-intel-06-55-0x-ipu-2020.2" inside
|
||||
/lib/firmware/<kernel_version> directory, run
|
||||
"/usr/libexec/microcode_ctl/update_ucode" to add it to firmware directory
|
||||
where microcode will be available for late microcode update, and run
|
||||
"dracut -f --kver <kernel_version>", so initramfs for this kernel version
|
||||
is regenerated and the microcode can be loaded early, for example:
|
||||
|
||||
touch /lib/firmware/3.10.0-862.9.1/force-intel-06-55-0x-ipu-2020.2
|
||||
/usr/libexec/microcode_ctl/update_ucode
|
||||
dracut -f --kver 3.10.0-862.9.1
|
||||
|
||||
After that, it is possible to perform a late microcode update by executing
|
||||
"/usr/libexec/microcode_ctl/reload_microcode" or by writing value "1" to
|
||||
"/sys/devices/system/cpu/microcode/reload" directly.
|
||||
|
||||
To disallow usage of the latest microcode revision for a specific kernel
|
||||
version, please create a file "disallow-intel-06-55-0x-ipu-2020.2" inside
|
||||
/lib/firmware/<kernel_version> directory, run
|
||||
"/usr/libexec/microcode_ctl/update_ucode" to update firmware directory
|
||||
used for late microcode updates, and run "dracut -f --kver <kernel_version>",
|
||||
so initramfs for this kernel version is regenerated, for example:
|
||||
|
||||
touch /lib/firmware/3.10.0-862.9.1/disallow-intel-06-55-0x-ipu-2020.2
|
||||
/usr/libexec/microcode_ctl/update_ucode
|
||||
dracut -f --kver 3.10.0-862.9.1
|
||||
|
||||
To enforce addition of this microcode for all kernels, please create a file
|
||||
"/etc/microcode_ctl/ucode_with_caveats/force-intel-06-55-0x-ipu-2020.2", run
|
||||
"/usr/libexec/microcode_ctl/update_ucode" for enabling late microcode updates,
|
||||
and "dracut -f --regenerate-all" for enabling early microcode updates:

mkdir -p /etc/microcode_ctl/ucode_with_caveats
