The Linux kernel was released Kernel 5.0.
Previously intended for version 4.21, the new version comes with a full set of improvements (as expected).
But do not expect Grand changes because there is new version number.
Linus Torvalds explains: “the Change in numbering does not indicate anything special. If you want to have the official reason, I ran out of fingers and toes, so 4.21 was 5.0 “.
Linux Kernel 5.0
So what’s new in Linux Kernel 5.0?
But, as always, the bulk of the improvements located on the lower level. The most major change is invisible, intangible and unexciting.
However, there are some notable new additions that are worth mentioning. It includes:
- Display support AMD FreeSync
- Support Raspberry Pi Touchscreen in the main core
- New console font for displays HiDPI / Retina
- Support a swap file Btrfs
- Adiantum data encryption
- Logitech high resolution scroll
The above list is not exhaustive, but a selective overview of the most noteworthy changes.
However, you can read a bit more about some of the things listed above.
Adiantum Data Encryption
First support Adiantum in fscrypt. Adiantum is a drop in replacement for Google’s (controversial) NSA-developed Speckle.
Adiantum provides a fast data encryption on younger devices and equipment (it is used in Android devices Go). The usual Linux desktops also can use this technology with native support for fscrypt EXT4 and F2FS.
This is the function that you will use?
Display support AMD FreeSync
Fans of dynamic updates and of absence of discontinuities of the screen will be pleased to know that AMD FreeSync works with hard core Linux 5.0 (although this also requires MESA 19.0 and some other updates).
To use this, you will need an AMD Radeon R5 / R7 / R9 200 or later (including Vega) and a monitor that supports FreeSync technology.
Support Raspberry Pi Touchscreen Linux
Linux 5.0 comes with driver touch screen Raspberry Pi out of the box.
The people behind the successful line of single-Board computers, released official 7-inch touchscreen display for the Raspberry Pi. As the computer to which it connects, it’s pretty cheap (about £ 60) and is quite versatile. It supports touch to 10 fingers and a resolution of 800 × 480 pixels.
Linux 5.0, this touch screen works with the main Linux kernel, no detours required.
Support other equipment
Every Linux kernel tries to keep up with the development of technology. This time among the newly issued and (or) hardware development that receives preliminary support:
- Intel Graphics Icelake Gen11
- NXP i.MX8 SoC & Layerscape LX2160A
- RDA Micro RDA8810PL
- NVIDIA Turing
- Display support NVIDIA Xavier
Support of existing equipment is also improved due to the small number of changes, characteristic for a specific device.
For example, users of ThinkPad laptops and ASUS can now use special keyboard shortcuts on their machines, and the addition of new driver for the adapter Aquiantia AQtion USB-to-Ethernet must provide reliable networking capabilities.
Accessories and peripherals that get updated support include gaming keyboard Cougar 700K and Logitech mouse with a scrolling Logitech High Resolution.
Add ARM big.LITTLE Energy Aware Scheduling can support the system to improve CPU power solution and provide a slight increase in performance.
Download Linux 5.0 Kernel
The source code for Linux 5.0 available for download now, but it will not be very useful if you don’t know what to do with it.
The upcoming release of Ubuntu 19.04 almost certainly will include Linux 5.0 Kernel (or later a small revision, if it appears to hang the kernel on 1 April).
However, you do not need to wait until then. You can install the main core in Ubuntu using a tool like Ukuu.
But this is not recommended. The official kernel of Ubuntu Linux includes Ubuntu-specific patches, tweaks and other additions; your system may work worse on the main kernel than Ubuntu.
