Check Processor Compatibility
|
|
#############################
|
|
|
|
Before installing |CL-ATTR|, check your host system's processor compatibility using one of
|
|
the following options:
|
|
|
|
.. note::
|
|
This does not check other system components (for example: storage and
|
|
graphics) for compatibility with |CL|.
|
|
|
|
Option 1: Use the :command:`clear-linux-check-config.sh` script on an existing Linux system
|
|
*******************************************************************************************
|
|
|
|
#. Download the `clear-linux-check-config.sh`_ file.
|
|
|
|
If a browser is not available, use:
|
|
|
|
.. code-block:: bash
|
|
|
|
curl -O https://cdn.download.clearlinux.org/current/clear-linux-check-config.sh
|
|
|
|
#. Make the script executable.
|
|
|
|
.. code-block:: bash
|
|
|
|
chmod +x clear-linux-check-config.sh
|
|
|
|
#. Run the script.
|
|
|
|
#. Check to see if the host's processor is capable of running |CL|.
|
|
|
|
.. code-block:: bash
|
|
|
|
./clear-linux-check-config.sh host
|
|
|
|
#. Check to see if the host is capable of running |CL| in a container.
|
|
|
|
.. code-block:: bash
|
|
|
|
./clear-linux-check-config.sh container
|
|
|
|
The script prints a list of test results similar to the output below.
|
|
All items should return a `SUCCESS` status. This example indicates the
|
|
host's processor supports running |CL|.
|
|
|
|
.. code-block:: console
|
|
|
|
Checking if host is capable of running Clear Linux* OS
|
|
|
|
SUCCESS: 64-bit CPU (lm)
|
|
SUCCESS: Supplemental Streaming SIMD Extensions 3 (ssse3)
|
|
SUCCESS: Streaming SIMD Extension v4.1 (sse4_1)
|
|
SUCCESS: Streaming SIMD Extensions v4.2 (sse4_2)
|
|
SUCCESS: Carry-less Multiplication extensions (pclmulqdq)
|
|
|
|
Option 2: Use a |CL| live image on a non-Linux system
|
|
=====================================================
|
|
|
|
#. `Download`_ either the `Desktop` or `Server` version of the live image ISO.
|
|
|
|
#. Follow the instruction to :ref:`bootable-usb`.
|
|
|
|
#. Boot up the |CL| live image on the USB.
|
|
|
|
#. Check compatibility as follows:
|
|
|
|
* *Desktop version:*
|
|
|
|
a. Open a terminal.
|
|
|
|
#. Check compatibility.
|
|
|
|
.. code-block:: bash
|
|
|
|
sudo clr-installer --system-check
|
|
|
|
* *Server version:*
|
|
|
|
a. Log in as `root` and set a password.
|
|
|
|
#. Check compatibility.
|
|
|
|
.. code-block:: bash
|
|
|
|
clr-installer --system-check
|
|
|
|
Expected output for a compatible host processor:
|
|
|
|
.. code-block:: console
|
|
|
|
Checking for required CPU feature: lm [success]
|
|
Checking for required CPU feature: sse4_2 [success]
|
|
Checking for required CPU feature: sse4_1 [success]
|
|
Checking for required CPU feature: pclmulqdq [success]
|
|
Checking for required CPU feature: ssse3 [success]
|
|
Success: System is compatible
