WARNING:

These microcodes are for *compatibility testing* and *kernel SSBD support
validation* only.  They could interoperate badly with any specific system's
firmware or hardware configuration, causing the system to misbehave, up to and
including incorrect system operation, data loss, data corruption, and firmware
soft-bricking.

Use at your own risk.  When in doubt, DO NOT use.  You are the sole party
responsible for any damage that installing these microcode updates could cause
to the system or data.

** Warning: 0x706a1 rev 0x26 is under recall due to possible issues, the
previous production version was included in the meantime to make the need to
revert very clear.

Warning: Several microcode updates are still missing.



How to install:

1. place the extra microcode data file in /usr/share/misc, ensure it is mode
   0644, owner root, group root.

2. install the regular intel-microcode package, it will detect the extra microcode
   pack in /usr/share/misc/intel-microcode* and use it as a possible source of
   microcode updates.

   Alternatively, if intel-microcode is already installed, just regenerate the
   initramfs:  update-initramfs -u

3. Reboot.

4. Report any issues or issues to the Debian bug tracking system, package
   intel-microcode, tag experimental, severity minor.


How to remove:

1. rm /usr/share/misc/intel-microcode-*

2. update-initramfs -u

3. reboot.


How to temporarily disable it if the system won't boot:

1. enter the command line mode of your bootloader (likely grub2)

2. append to the end of the kernel command line the following command:
   dis_ucode_ldr

3. boot normally, the microcode update will not be active.  Proceed with the
   how-to-remove section above

4. report the issue.


Notes:
* Only microcodes declared to be in "production" by Intel in their sa00115 microcode
  update guidance list, dated 2018-07-13, are included in this data file.
