Check Processor Compatibility¶

Before installing Clear Linux* OS, 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 Clear Linux OS.

Option 1: Use the 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:

curl -O https://cdn.download.clearlinux.org/current/clear-linux-check-config.sh

Make the script executable.
```
chmod +x clear-linux-check-config.sh
```

Run the script.

Check to see if the host’s processor is capable of running Clear Linux OS.
```
./clear-linux-check-config.sh host
```
Check to see if the host is capable of running Clear Linux OS in a container.
```
./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 Clear Linux OS.

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 Clear Linux OS live image on a non-Linux system¶

Download either the Desktop or Server version of the live image ISO.
Follow the instruction to Create a bootable USB drive using Etcher*.
Boot up the Clear Linux OS live image on the USB.

Check compatibility as follows:

Desktop version:
1. Open a terminal.
2. Check compatibility.
```
sudo clr-installer --system-check
```
Server version:
1. Log in as root and set a password.
2. Check compatibility.
```
clr-installer --system-check
```

Expected output for a compatible host processor:

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
