KVM Enhancements Within The Linux 6.14 Kernel

([Virtualization] 3 Hours Ago Linux 6.14 KVM)


Along with other [1]Intel TDX changes and [2]AMD SEV updates separately sent out for thei n-development [3]Linux 6.14 kernel, there is the usual hearty batch of Kernel-based Virtual Machine (KVM) virtualization updates too.

Some of the KVM changes that were merged during the nearly-over Linux 6.14 merge window include:

- Removing a redundant TLB flush on AMD CPUs when the guest CR4.PGE changes.

- Overhauling of the KVM x86 CPUID feature infrastructure to track all vCPU capabilities.

- Continued work around enabling Intel Trust Domain Extensions (TDX) virtual machines.

- A rework of KVM handling around VM-Exits during event vectoring to bring better parity between VMX and SVM usage.

- The RISC-V KVM support now enables Zabha, Svvptc, and Ziccrse extension support for guests.

- Various other bug fixes and enhancements.

More details on these KVM feature changes for Linux 6.14 via [4]this pull request that was already merged to mainline Linux Git.

Man Charged With Crashing Windows

MOUNTAIN HOME, AR -- Eric Turgent, a closet Linux advocate, was arrested
yesterday for intentionally crashing his co-worker's Windows box at the
offices of the "Roadkill Roundup" newspaper. Turgent disputes the charges,
saying, "If causing an operating system to crash is illegal, than why
isn't Bill Gates serving life without parole?"

Turgent's co-worker, Mr. Stu Poor, the clueless technology pundit for the
newspaper, is a heavy Microsoft supporter. He frequently brags in his
weekly Tech Talk column that he "once had a conversation with Bill Gates."
A heated argument broke out yesterday morning in which the two insulted
each other ("You're nothing but a Linux hippie freak on the Red Hat
payroll!" vs. "You make Jesse Berst and Fred Moody look like [expletive]
geniuses!") for two hours.

At the heat of the moment, Turgent shoved Poor aside and typed in
"C:\CON\CON". The machine crashed and the pundit lost all of his work (a
real loss to humanity, to be sure). Turgent is in jail awaiting trial for
violating the "Slash Crashes Act". This bill was enacted in 1999 after a
Senator's gigabyte cache of pornography was destroyed by a Windows crash.
