|
||||
FEX presents a Linux 5.0 interface to the guest, and supports both AArch64 and x86-64 as hosts.
|
||||
FEX is very much work in progress, so expect things to change.
|
||||
|
||||
|
||||
## Quick start guide
|
||||
### For Ubuntu 20.04, 21.04, 21.10, 22.04
|
||||
Execute the following command in the terminal to install FEX through a PPA.
|
||||
|
||||
`curl --silent https://raw.githubusercontent.com/FEX-Emu/FEX/main/Scripts/InstallFEX.py | python3`
|
||||
|
||||
This command will walk you through installing FEX through a PPA, and downloading a RootFS for use with FEX.
|
||||
|
||||
Ubuntu PPA is updated with our monthly releases.
|
||||
|
||||
### For everyone else
|
||||
Follow the guide on the official FEX-Emu Wiki [Here](https://wiki.fex-emu.org/index.php/QuickStartGuide)
|
||||
|
||||
## Getting Started
|
||||
FEX has been tested to build and run on ARMv8.0, ARMv8.1+, and x86-64(AVX or newer) hardware.
|
||||
ARMv7 and older x86 hardware will not work.
|
||||
Expected operating system usage is Linux. FEX has been tested with Ubuntu 20.04, 20.10, and 21.04. Also Arch Linux.
|
||||
|
||||
On AArch64 hosts the user **MUST** have an x86-64 RootFS [Creating a RootFS](#RootFS-Generation).
