As expected, Linus Torvalds Linux Kernel 5.14 yesterday, Sunday. As always, the new kernel brings better hardware support. At 5.14, this includes full support for the Raspberry Pi 400 and support for the , a SoC with a 4-core ARM A55 CPU and Mali G52 2EE GPU. The two smartphones Sony Xperia 1, 1II and 5 as well as 5II receive initial support. Microsoft’s Android Phone with Qualcomm’s SM8150 (Snapdragon 855) SoC also receives better support.
The RISC-V architecture also receives important updates with Linux 5.14. This includes support forand for KFENCE, the detector with Kernel 5.12 error introduced , which ensures that kernels can be tested in productive operation with very little overhead. The virtualization driver VirtIO-IOMMU now also works , while it was actually designed for AArch64.
In the graphics area, Linux 5.14 brings support for Intel’s upcoming hybrid Alder Lake P CPUs for mobile devices as well as for the AMD GPUs Beige Goby and Yellow Carb. AMD graphics cards will also be hot and unpluggable in the future, so they can be removed at runtime. This can be useful when using an external GPU or when returning a GPU from a virtual machine to the host. Microsoft developers have submitted a Hyper-V DRM driver that is now supported with 5.14. This DRM driver supports Microsoft’s Hyper-V for screen output in a virtualized environment and allows the use of kernel mode setting (KMS).

readonlyadded to compress the partition with compression enabled, which is useful for Android RO partitions.
Like the previous kernel, 5.14 brings improvements in the support of. A new function that is particularly interesting for cloud providers is in order to mitigate the negative consequences of preventing attacks via Specter.
As always, all other changes can be on the websitetracked , which will be completed over the next few days.
