Using Rust to Write Safe and Correct Linux Kernel Drivers

As part of the Rust for Linux project, aimed to make it possible to use Rust for Linux driver development, the Android team at Google is working on evaluating the benefits that using Rust would bring.

Rust for Linux was announced by Miguel Ojeda approximately one year ago on LKML, the Linux Kernel Mailing List, as an attempt to bring a second language to Linux kernel development by extending the Linux build system. Specifically, the project seeks to enable the use of Rust to write drivers and other “leaf” kernel modules, but not for the kernel core or the major kernel subsystems.

We feel that Rust is now ready to join C as a practical language for implementing the kernel. It can help us reduce the number of potential bugs and security vulnerabilities in privileged code while playing nicely with the core kernel and preserving its performance characteristics.

Serde Rust: Serialization Framework for Rust

Serde

*Serde is a framework for serializing and deserializing Rust data structures efficiently and generically.*

You may be looking for:

Serde in action

Click to show Cargo.toml. Run this code in the playground.

[dependencies]

# The core APIs, including the Serialize and Deserialize traits. Always
# required when using Serde. The "derive" feature is only required when
# using #[derive(Serialize, Deserialize)] to make Serde work with structs
# and enums defined in your crate.
serde = { version = "1.0", features = ["derive"] }

# Each data format lives in its own crate; the sample code below uses JSON
# but you may be using a different one.
serde_json = "1.0"

 

use serde::{Serialize, Deserialize};

#[derive(Serialize, Deserialize, Debug)]
struct Point {
    x: i32,
    y: i32,
}

fn main() {
    let point = Point { x: 1, y: 2 };

    // Convert the Point to a JSON string.
    let serialized = serde_json::to_string(&point).unwrap();

    // Prints serialized = {"x":1,"y":2}
    println!("serialized = {}", serialized);

    // Convert the JSON string back to a Point.
    let deserialized: Point = serde_json::from_str(&serialized).unwrap();

    // Prints deserialized = Point { x: 1, y: 2 }
    println!("deserialized = {:?}", deserialized);
}

Getting help

Serde is one of the most widely used Rust libraries so any place that Rustaceans congregate will be able to help you out. For chat, consider trying the #rust-questions or #rust-beginners channels of the unofficial community Discord (invite: https://discord.gg/rust-lang-community), the #rust-usage or #beginners channels of the official Rust Project Discord (invite: https://discord.gg/rust-lang), or the #general stream in Zulip. For asynchronous, consider the [rust] tag on StackOverflow, the /r/rust subreddit which has a pinned weekly easy questions post, or the Rust Discourse forum. It's acceptable to file a support issue in this repo but they tend not to get as many eyes as any of the above and may get closed without a response after some time.

How To Install A Device Driver On Linux- 2 Methods › Servo Node

Itching your head due to missing device driver on your machine? Looking for how to install a device drive on a Linux system? Just switched to a new OS, but hardware is not working well? Check out this article to learn how you can install a missing device drive on your Linux system.

Installing and configuring a driver on a Linux based machine is quite daunting for those who just switched to Linux from Windows/Mac, or trying the new OS with dual boot. The widely used windows and Mac operating system often makes it a user-friendly experience when it comes to install device drivers, but in case of a Linux OS, the user might find some of their hardware is not working. Well, this would not be an issue anymore.

Is it challenging to install a device driver on Linux?
For Windows and Mac OS users, it’s really an easy approach to install any device driver as the OS detects those automatically. Also, the users can download the missing ones from the internet, and just click on a simple wizard to have the driver installed.

However, in case of a Linux platform, the process is not enough simple. One of the most common reason is, Linux is an open-source OS and a number of variations available. So, there can’t be a single method that can suit all Linux platforms, and every of the distribution has its own way regarding how to install a device driver on system.

In addition, most of the default Linux drivers are open-source and integrated in the system, and this makes the installation of missing drivers quite complicated, if not included already with OS. Still, most of the useful drivers are automatically detected with popular Linux distros.

Another reason why installing a device driver on a Linux can be complicated is license policies which technically vary among Linux distributions. Such as Fedora restricts to include drivers which are legally prohibited or violate cyber laws. Even Ubuntu asks its users to prevent using closed hardware.

Means, installing a device driver on a Linux can be a bit challenging, but still here mentioned 2 approaches can be helpful.

Two Methods To Find Drivers & Install on Linux
Approach 1: Using Built-in Interface
Approach 2: Using Command Line

How To Install NVIDIA Graphics Drivers In Linux- Ubuntu/Debian/Fedora

This tutorial is subjected to those who have Linux installed on their desktop and want to install Nvidia graphics driver. Although, most of the newly released Linux distributions come with pre-installed Nvidia drivers, usually in form of Nouveau open-source graphics driver that supports Nvidia graphics cards. Means, if you install a Linux platform, you may require no additional drivers for your graphics card.

But, in case if you are a game lover and want to use as possible from your Nvidia graphics card, then you might need to install official Nvidia drivers for Linux. As already mentioned, most of the Linux platfroms offer proprietary driver package as a part of its standard repository, it’s much easier to install drivers on your desktop.

Alternatively, the users can also seek to download and install latest Nvidia Linux drivers from its official website as well. However, this require users to follow up some hands on measures.

How to install Nvidia graphics driver in Linux?
In order to install Nvidia graphics driver in Linux, you first need to do a number of tasks in prior, that includes:

Checking current VGA driver
Checking Nvidia Linux driver version
Checking current model of Nvidia VGA card
