Linux 5.6 has come when we are still experiencing better hardware support from Linux 5.5 stable distribution.
To be honest, Linux 5.6 is more exciting than 5.5. Even if the upcoming Ubuntu 20.04 lts release will come with Linux 5.5, you need to really understand what the Linux 5.6 kernel provides for us.
In this article, I'll focus on the key changes and features to look forward to in the Linux 5.6 release:
Linux 5.6 features highlights
When Linux 5.6 has new news, I will try to update this feature list. But now let's take a look at what we know:
1. Wireguard support
Wireguard will be added to Linux 5.6 and may replace OpenVPN for various reasons.
You can learn more about the advantages of wireguard on the official website. Of course, if you've used it, you probably already know why it's better than OpenVPN.
Similarly, Ubuntu 20.04 lts will support wireguard.
2. Support USB4
Linux 5.6 will also support USB4.
If you don't know USB 4.0 (USB4), you can read thisFile。
According to the documents,
In addition, although we all know that USB4 is based on thunderbolt interface protocol, it will be backward compatible with USB 2.0, USB 3.0 and thunderbolt 3, which will be good news.
3. Use LZO / lz4 to compress f2fs data
Linux 5.6 will also support compression of f2fs data using the LZO / lz4 algorithm.
In other words, this is just a new compression technology for Linux file system. You can choose the pending file expansion technology.
4. Solve the problem of 32-bit system in 2038
UNIX and Linux store time values in 32-bit signed integer format with a maximum value of 2147483647. If the time value exceeds this value, it will be stored as a negative number due to integer overflow.
This means that for 32-bit systems, the time value cannot exceed 2147483647 seconds after January 1, 1970. That is, at 03:14:07 on January 19, 2038 UTC time, due to integer overflow, the time will be displayed as December 13, 1901 instead of January 19, 2038.
Linux kernel 5.6 solves this problem, so 32-bit system can also run after 2038.
5. Improve hardware support
Obviously, hardware support will continue to improve in the next release. Support for new wireless peripherals is also a priority.
Support for MX Master 3 mouse and other Logitech Wireless products will be added in the new kernel.
In addition to Logitech's products, you can expect support for many different hardware (including amd GPU, NVIDIA GPU and Intel tiger Lake chipset).
6. Other updates
In addition, in Linux 5.6, in addition to the above major new features or support, the next kernel version will also make some other improvements:
Improve amd Zen's temperature / power report repair AMD CPU overheating in Asustek flight fortress series notebook open source support NVIDIA RTX 2000 Turing Series graphics card built-in fscrypt encryption
Phoronix keeps track of many of the technical changes that Linux 5.6 brings. So if you're curious about all the changes involved in Linux 5.6, take a look for yourself.
