Linux Kernel 6.0 RC1 is out with Run-Time Kernel Verification
|
||||
======
|
||||
Linus Torvalds releases Linux Kernel 6.0 RC1 for everyone to test, and here’s a feature recap.
|
||||
|
||||
![Linux Kernel 6.0][1]
|
||||
|
||||
Following the [Linux Kernel 5.19][2] released a few days back, Linus [released the first release candidate][3] of Linux 6.0 for testing. It officially closes the merge window for this release while you test.
|
||||
|
||||
### Why 6.0?
|
||||
|
||||
Usually, the mainline Kernel version increases by the minor version and this release should have been Kernel 5.20. However, Linus decided to increase the significant version number, hence the Kernel 6.0.
|
||||
|
||||
> Despite the major number change, there’s nothing fundamentally different about this release – I’ve long eschewed the notion that major numbers are meaningful, and the only reason for a “hierarchical” numbering system is to make the numbers easier to remember and distinguish. Which is why when the minor number gets to around 20 I prefer to just increment the major number instead and reset to something smaller.
|
||||
|
||||
Let’s take a look at what’s in store.
|
||||
|
||||
### Linux Kernel 6.0 RC1 – New Features
|
||||
|
||||
#### Processors
|
||||
|
||||
AMD Zen systems gets a [performance boost][4] with updated NUMA balancing in the Kernel scheduler.
|
||||
|
||||
The Ratbleed speculative execution exploits fixing [continues][5] in this release affecting Intel 8th Gen+ and AMD Zen 1+ CPU family. Although the Ratbleed has not yet been found in the wild (only in Lab), the fix continues in this Kernel.
|
||||
|
||||
Lenovo and AMD [bring][6] the Automatic Mode Transition (AMT) support for Ryzen power ThinkPad laptops. This feature should give firmware-based power handling in those laptops with better efficiency.
|
||||
|
||||
New audio hardware [support][7] for AMD Ryzen 7000 desktop processors (Raphael) lands in this release with ACP 6.x support.
|
||||
|
||||
AMD is [preparing][8] for the release day with additional Instruction based sampling support for the Zen 4 series.
|
||||
|
||||
More CPU [temperature monitoring code][9] lands for AMD 17th and 19th family of models.
|
||||
|
||||
Initial work starts landing for Lenovo’s ARM Laptop X13 featuring Qualcomm Snapdragon 8cx Gen3 (SC8280XP) CPU.
|
||||
|
||||
Likewise, in all releases, a bunch of SOC chips get support in Linux Kernel 6. The most notable ones include NXP i.MX93 SoC (primarily used for smart devices in home solutions).
|
||||
|
||||
Here’s a quick list (not complete) of the SOCs that gets [support][10] in this instalment.
|
||||
|
||||
* Broadcom SOCs for broadband devices * BCM63178 * BCM63158 * BCM4912 * BCM6858 * BCM6878 * BCM6846 * BCM63146 * BCM6856 * BCM6855 * BCM6756 * BCM63148 * BCM6813
|
||||
* Allwinner’s H616 (IPTV, OTT streaming)
|
||||
* Marvell Prestera 98DX2530
|
||||
* Google Chameleon v3 FPGA
|
||||
|
||||
In addition, a bunch of RISC-V processor code was introduced with an aim to support it in future.
|
||||
|
||||
#### GPU
|
||||
|
||||
Work continues in this Kernel release for Intel DG2/Alchemist and AMD RDNA3 graphics cards; the support is entirely not there but is in progress for future versions.
|
||||
|
||||
A bunch of frame buffer device driver [update][11] (mostly fixes) arrives for Atari GPUs. Most noteworthy are the patchsets to fix VGA modes, colour handling and numerous code clean-ups.
|
||||
|
||||
Intel Meteor Lake GPU [support][12] is starting up in this release.
|
||||
|
||||
#### Storage and file systems
|
||||
|
||||
Like all releases, the famous and supported file systems are updated and improved.
|
||||
|
||||
Since the usage of SSDs is increasing, the flash-friendly file system (F2FS) [enhances][13] memory handling, garbage collection optimization and more.
|
||||
|
||||
One Microsoft employee provides a [patch][14] to improve locking performance & reliability for CIF/SMB3 protocol to improve multi-channel operation over the network.
|
||||
|
||||
#### Additional Changes
|
||||
|
||||
Other noteworthy changes across this Kernel release include early work for Wi-Fi 7 support, more feature updates on the ongoing random number generation and setting up system hostname via Kernel parameter.
|
||||
|
||||
Furthermore, one of the vital features is the “Run-Time Verification” codebase which helps Linux run in safety-critical infrastructure. The method takes an approach where the system specification instruction set is compared against the actual execution instruction set by re-implementing instruction sets at run-time. This is based on a paper which you can read [here][15]. The actual patch is present on this [page][16].

||||

||||
### Download

|
||||
|
||||
If you are running benchmarks, testing new hardware and finding issues, report to the Kernel mailing list.
|
||||
|
||||
The Linux Kernel 6.0 is expected to be released by the beginning of Q4 2022, i.e. October timeframe. Hence, Ubuntu 22.10 may get this version (although I am doubtful about that).
