Sent in this morning for Linux 5.19 is AMD SEV-SNP support for that hardware feature introduced last year with AMD EPYC Milan 7003 series processors. Meanwhile Intel's alternative technology, Trust Domain Extensions (TDX) is coming with Xeon Scalable "Sapphire Rapids" and also with Linux 5.19 that functionality is being readied on the software side.

AMD SEV-SNP Finally Being Merged In Linux 5.19 To Enhance Confidential Computing
AMD SEV-SNP Finally Being Merged In Linux 5.19 To Enhance Confidential Computing
2 Hours Ago - AMD - AMD SEV-SNP - Add A Comment

Last year with the launch of AMD EPYC 7003 "Milan" processors one of the new security features was SEV-SNP, or the "Secure Nested Paging" update to the Secure Encrypted Virtualization functionality that has built up with succeeding EPYC generations. While AMD published out-of-tree kernel patches in a GitHub repository to enable SEV-SNP and has been volleying several revisions to them on the kernel mailing list, one year later it's finally arriving in mainline with the Linux 5.19 kernel.

22 May 07:04 AM EDT - Linux Kernel - Linux 5.19 Features - 5 Comments

Unless Linus Torvalds has reservations today about the changes to land in the kernel this past week and decides to issue an extra RC, Linux 5.18 is expected to be christened as stable today and that in turn will mark the start of the Linux 5.19 merge window. Based on the "-next" activity, here is a look at the many changes expected to be merged for Linux 5.19.

Back in 2019 Chinese CPU company Zhaoxin introduced "LuJiaZui" as their 16nm x86 CPU design for use from laptops up through servers. LuJiaZui is much improved from their earlier chips though still well behind AMD and Intel performance. Proper GCC compiler support for LuJiaZui was sent out again this week after their previous upstreaming attempt hadn't made it into GCC 12 due to being late in the cycle.

Fedora will keep around its legacy BIOS support that was decided earlier this month after a proposal to deprecate legacy BIOS support to focus resources on UEFI-only booting. However, Fedora will be relying more on the community to maintain that legacy boot support and as such the Fedora BIOS Boot SIG (Special Interest Group) is now established.

While the kernel-side Intel AMX support landed in Linux 5.16 and KVM support for AMX in Linux 5.17, other Linux patches around Advanced Matrix Extensions (AMX) remain floating around. One important patch-set was updated this week for ensuring proper power management on AMX-enabled processors, coming with Xeon Scalable "Sapphire Rapids" this year.

Linux To Introduce The Ability To Set The Hostname Before Userspace Starts
Linux To Introduce The Ability To Set The Hostname Before Userspace Starts
20 May 12:00 AM EDT - Linux Kernel - Linux Kernel hostname= - 22 Comments

While the hostname on Linux systems is widely relied upon for different applications, setting the hostname is usually left up to user-space by the init system at boot. However, should any user-space processes try to read the system hostname prior to it being set, it could lead to unintended results. So now finally in 2022 there is a kernel parameter working its way upstream with "hostname=" should you want to ensure the hostname is set before user-space is started.
