The information regarding enforcing microcode update is provided below.
|
||||
|
||||
To enforce usage of the latest 06-5e-03 microcode revision for a specific kernel
|
||||
version, please create a file "force-intel-06-5e-03" 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-06-5e-03
|
||||
/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 enforce addition of this microcode for all kernels, please create file
|

|

"/usr/libexec/microcode_ctl/update_ucode" for enabling late microcode updates,

|

/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:

/usr/libexec/microcode_ctl/update_ucode
|
||||
dracut -f --kver 3.10.0-862.9.1
|
||||
|
||||
To disable usage of the newer microcode revision for all kernels, please create
|
||||
file "/etc/microcode_ctl/ucode_with_caveats/disallow-intel-06-8e-9e-0x-dell",
|

run "/usr/libexec/microcode_ctl/update_ucode" to update firmware directories
|

used for late microcode updates, and run "dracut -f --regenerate-all"
|

so initramfs images get regenerated, for example:
|

|

mkdir -p /etc/microcode_ctl/ucode_with_caveats

The following keys are supported:

is empty string.
|

* "offset" - offset in device's configuration space where the value resides.
|
||||
Default is 0.
|
||||
* "size" - field size. Possible values are 1, 2, 4, or 8. Default is 4.
|
||||
* "mask" - mask applied to the values during the check. Default is 0.
|
||||
* "val" - comma-separated list of matching values. Default is 0.
|
||||
* "mode" - check mode, the way matches are interpreted:
|
||||
* "success-any" - check succeeds if there was at least one match,
|
||||
otherwise it fails.
|
||||
* "success-all" - check succeeds if there was at least one device checked
|

and all the checked devices have matches, otherwise the check fails.

* "fail-any" - check fails if there was at least one match, otherwise

pci_config_val mode=success-all device=30 function=3 vid=0x8086 did=0x2083 offset=0x84 size=4 mask=0x38 val=0x38,0x18,0x8

and all the checked values in every checked file has matched at least one

it fails (in accordance with "mode=success-all" semantics). This check fails
|
||||
if "-m" option is not specified.
|

* "dmi" performs checks for specific values available in DMI sysfs files
|

(present under /sys/devices/virtual/dmi/id/). The check fails if file

Default is empty string.
|

* "val" - a string to match DMI data against. Can be enclosed in single

or double quotes. Default is empty string.
|

* "mode" - check mode, the way matches are interpreted:

* "success-equal" - returns 0 if the value present in the file
|
||||
with the name supplied via the "key" parameter file under
|
||||
/sys/devices/virtual/dmi/id/ is equal to the value supplied as a value
|

of "val" parameter, otherwise 1.
|

* "success-equal" - returns 1 if the value present in the file

/sys/devices/virtual/dmi/id/ is equal to the value supplied as a value
|

It checks file /sys/devices/virtual/dmi/id/bios_vendor and fails if its

Affected microcode: intel-ucode/06-8e-09, intel-ucode/06-8e-0a,
|
||||
intel-ucode/06-8e-0b, intel-ucode/06-8e-0c,

intel-ucode/06-9e-09, intel-ucode/06-9e-0a,
|

intel-ucode/06-9e-0b, intel-ucode/06-9e-0c,
|
||||
intel-ucode/06-9e-0d.
|
||||
|
||||
Mitigation: previously published microcode revision 0xac/0xb4/0xb8 is used
|
||||
by default if /sys/devices/virtual/dmi/id/bios_vendor reports
|
||||
"Dell Inc."; otherwise, the latest microcode revision is used.
|
||||
Caveat with revision 0xca of microcode files is provided
|
||||
as a convenience for the cases where it was working well before.
