@ -7,25 +7,30 @@ approach to getting this microcode update is via a BIOS upgrade, Intel realizes
that this can be an administrative hassle. The Linux operating system and VMware
ESX products have a mechanism to update the microcode after booting.
This SlackBuild repackages the official Intel microcode tarball, placing the
microcode.dat file under /lib/firmware/microcode.dat, which can be later
uploaded using microcode_ctl utility (available from SlackBuilds.org).
This SlackBuild repackages the official Intel microcode archive.
The "microcode.dat" file is placed under /lib/firmware/microcode.dat and can be
later uploaded using microcode_ctl utility (available from SlackBuilds.org).
This approach (microcode.dat + microcode_ctl) is kept for compatibility reasons
and should be avoided whenever possible. * Use the solution described below. *
If the iucode_tool (available from SlackBuilds.org) is installed on the system,
this SlackBuild writes the microcodes with the file names expected by the Linux
kernel firmware loader and places them under /lib/firmware/intel-ucode
directory. In that case, the correct microcode is uploaded when the Intel
microcode kernel's module is loaded.
this SlackBuild will:
Please note that the method using the iucode_tool is preferred for multiple
reasons, one being the deprecation of the kernel's interface used by the
microcode_ctl utility.
1) write the microcodes with the file names as expected by the Linux kernel
firmware loader and place them under /lib/firmware/intel-ucode directory.
The correct microcode is uploaded when the Intel microcode kernel's module
is loaded.
If you need to load the microcode early during the boot:
1) read https://www.kernel.org/doc/Documentation/x86/early-microcode.txt
2) read the manual for iucode_tool, especially about --write-earlyfw option
3) make sure your kernel has the followings:
CONFIG_MICROCODE=y
CONFIG_MICROCODE_EARLY=y
CONFIG_MICROCODE_INTEL=y
CONFIG_MICROCODE_INTEL_EARLY=y
2) write the microcodes to an early initramfs archive: /boot/intel-ucode.cpio
This archive should be prepended to the regular initramfs to allow
the kernel to update processor microcode very early during system boot.
To get started with early microcode loading, please have a look at:
1) https://www.kernel.org/doc/Documentation/x86/early-microcode.txt
2) iucode_tool man page, especially about --write-earlyfw option.
For example, on my system that uses syslinux, to load the microcode early
during the boot process, the configuration file reads something like that:
INITRD /boot/intel-ucode.cpio,/boot/initrd-generic-4.4.x.gz
