四大亮点带你看 Linux Kernel 5.6
|
|||
|
|
======
|
|||
|
|
|
|||
|
|
当我们体验 Linux 5.5 稳定发行版带来更好的硬件支持时，Linux 5.6 已经来了。
|
|||
|
|
|
|||
|
|
说实话，Linux 5.6 比 5.5 更令人兴奋。即使即将发布的 Ubuntu 20.04 LTS 发行版将开箱集成 Linux 5.5，你也需要真正了解 Linux 5.6 kernel 为我们提供的功能。
|
|||
|
|
|
|||
|
|
我将在本文中重点介绍Linux 5.6 发行版中值得期待的关键更改和功能：
|
|||
|
|
|
|||
|
|
### Linux 5.6 功能亮点
|
|||
|
|
|
|||
|
|
![][1]
|
|||
|
|
|
|||
|
|
I’ll try to keep the list of features up-to-date whenever there’s a piece of new information on Linux 5.6. But, for now, let’s take a look at what we already know so far:
|
|||
|
|
|
|||
|
|
#### 1\. 支持 WireGuard
|
|||
|
|
|
|||
|
|
WireGuard will be added to Linux 5.6 – potentially replacing [OpenVPN][2] for a variety of reasons.
|
|||
|
|
|
|||
|
|
You can learn more about [WireGuard][3] on their official site to know the benefits. Of course, if you’ve used it, you might be aware of the reasons why it’s potentially better than OpenVPN.
|
|||
|
|
|
|||
|
|
Also, [Ubuntu 20.04 LTS will be adding support for WireGuard][4].
|
|||
|
|
|
|||
|
|
#### 2\. 支持 USB4
|
|||
|
|
|
|||
|
|
Linux 5.6 will also include the support of **USB4**.
|
|||
|
|
|
|||
|
|
In case you didn’t know about USB 4.0 (USB4), you can read the [announcement post][5].
|
|||
|
|
|
|||
|
|
As per the announcement – “_USB4 doubles the maximum aggregate bandwidth of USB and enables multiple simultaneous data and display protocols._“
|
|||
|
|
|
|||
|
|
Also, while we know that USB4 is based on the Thunderbolt protocol specification, it will be backward compatible with USB 2.0, USB 3.0, and Thunderbolt 3 – which is great news.
|
|||
|
|
|
|||
|
|
#### 3\. 使用 LZO/LZ4 压缩 F2FS 数据
|
|||
|
|
|
|||
|
|
Linux 5.6 will also come with the support for F2FS data compression using LZO/LZ4 algorithms.
|
|||
|
|
|
|||
|
|
In other words, it is just a new compression technique for the Linux file-system where you will be able to select particular file extensions.
|
|||
|
|
|
|||
|
|
#### 4\. 解决 32 位系统的 2038 年问题
|
|||
|
|
|
|||
|
|
Unix and Linux store the time value in a 32-bit signed integer format which has the maximum value of 2147483647. Beyond this number, due to integer overflow, the values will be stored as a negative number.
|
|||
|
|
|
|||
|
|
This means that for a 32-bit system, the time value cannot go beyond 2147483647 seconds after Jan. 1, 1970. In simpler terms, after 03:14:07 UTC on Jan. 19, 2038, due to integer overflow, the time will read as Dec. 13, 1901 instead of Jan. 19, 2038.
|
|||
|
|
|
|||
|
|
Linux kernel 5.6 has a fix for this problem so that 32-bit systems can run beyond the year 2038.
|
|||
|
|
|
|||
|
|
#### 5\. 改进硬件支持
|
|||
|
|
|
|||
|
|
Obviously, with the next release, the hardware support will improve as well. The plan to support newer wireless peripherals will be a priority too.
|
|||
|
|
|
|||
|
|
The new kernel will also add the support for MX Master 3 mouse and other wireless Logitech products.
|
|||
|
|
|
|||
|
|
In addition to Logitech products, you can expect a lot of different hardware support as well (including the support for AMD GPUs, NVIDIA GPUs, and Intel Tiger Lake chipset support).
|
|||
|
|
|
|||
|
|
#### 6\. 其他更新
|
|||
|
|
|
|||
|
|
Also, in addition to all these major additions/support in Linux 5.6, there are several other changes that would be coming with the next kernel release:
|
|||
|
|
|
|||
|
|
* Improvements in AMD Zen temperature/power reporting
|
|||
|
|
* A fix for AMD CPUs overheating in ASUS TUF laptops
|
|||
|
|
* Open-source NVIDIA RTX 2000 “Turing” graphics support
|
|||
|
|
* FSCRYPT inline encryption.
|
|||
|
|
|
|||
