As planned, Linus Torvalds has released a new version of his kernel. The kernel 4.15 is the new version of the Linux kernel that not only incorporates new features such as the inclusion and improvement of AMDGPU support but it is also the first kernel that brings by default the correction of the Meltdown and Specter vulnerabilities.
Linus Torvalds has never been a part of the patches that were created to correct Meltdown and Specter. To the point that he stated that they were a real rubbish and were worse than the problem itself. That is why this kernel is so important since it is a solution that has the approval of Linus Torvalds.
Kernel 4.15 incorporates these solutions, although the Linux Torvalds team says that a lot still needs to be done in this regard, so that these vulnerabilities are definitively resolved. This version of the kernel also incorporates better support for the driver and AMD GPU, the famous AMDGPU.
This will make graphics playable better in Gnu / Linux environments. A new cgroupv2 enabled CPU driver is also added. And just like other kernel versions, kernel 4.15 contains numerous bug fixes, new options enabled and others disabled, and new supported hardware that will make it work better on Gnu / Linux.
For the next few days the different distributions will incorporate this version of the kernel in their official repositories so that we can install it. However, if we have certain knowledge, we can create our own linux kernel, for this we just have to go to the official website of the kernel and download the source code for kernel 4.15. This solution is the best that exists because we can create an optimized kernel for our computer, but it is also true that this solution requires a high level of knowledge, otherwise, the result will be a failure and a problem for our computer.
