Installation for WRL LTS-17/9/8/7/6/5

Please update to the latest RCPL for all products.

1) Wind River Linux LTS-17

create a project
$setup.sh --machine ... ...
$cd layers/meta-intel-dl/downloads
$wget https://downloadmirror.intel.com/27431/eng/microcode-20180108.tgz
$cd layers/meta-intel
$git am --whitespace=nowarn WRLLTS17-intel-microcode-update-to-20180108.patch

2) Wind River Linux 9

create a project
$setup.sh --machine ... ...
$cd layers/wr-base
$git am --whitespace=nowarn WRL9-microcode-ctl-update-microcode-to-version-2018.patch

3) Wind River Linux 8

create a new project
$configure --enable-kernel=... --enable-board=... ...
$cd layers/wr-bsps/intel-x86
$git am --whitespace=nowarn WRL8-intel-x86-update-microcode-to-version-20180108.patch

4) Wind River Linux 7

create a new project
$configure --enable-kernel=... --enable-board=... ...
$cd layers/wr-bsps/intel-x86
$git am --whitespace=nowarn WRL7-intel-x86-update-microcode-to-version-20180108.patch

5) Wind River Linux 6

$configure --enable-kernel=... --enable-board=... ...
$cd layers/wr-bsps/intel-x86
$git am --whitespace=nowarn WRL6-intel-x86-update-microcode-to-version-20180108.patch

$cd layers/wr-base
$git am --whitespace=nowarn WRL5-intel-x86-update-microcode-to-version-20180108.patch


7) Wind River Pulsar Linux 8
On your target
$wget https://downloadmirror.intel.com/27431/eng/microcode-20180108.tgz
$tar zxvf microcode-20180108.tgz

Now you will get one directory and two files:

    intel-ucode
    microcode.dat
    releasenote

Check and remember your CPU's microcode version:
$cat /proc/cpuinfo | grep microcode
microcode    : 0xxx
...

Upgrade in *cube-essential*
$cp -r intel-ucode /lib/firmware
$echo 1 > /sys/devices/system/cpu/microcode/reload

check to see if the microcode upgraded
$cat /proc/cpuinfo | grep microcode
microcode : 0xxx
...

Now the microcode should changed to a bigger value. Upgrade accomplished.
