Intel Engineers Begin Landing Open-Source Support For TDX, Intel Key Locker

Phoronix | Sept. 24, 2020, 6:47 a.m. | Original

Last month Intel published a whitepaper on TDX as Trust Domain Extensions as a means of better securing virtual machines. TDX allows for isolating VMs from the hypervisor and other non-VMM system software. Intel TDX builds off other recent work around MKTME memory encryption and other features. We are now beginning to see that software side support roll-out along with the also-new Key Locker instructions.

Last night hitting LLVM 12 Git was TDX instructions support. New instructions added are SEAMCALL for calling the SEAM VMX-root operation

Recent hardware enablement work on the Linux kernel is HPE bringing up UV5 support.

Succeeding the SGI UV4 support is now UV5 under the ownership of HPE. UV5 is the latest iteration of their x86_64 based supercomputer architecture.

The UV5 architecture patches aren't all that revealing with the primary change being 52-bits of physical address memory address space and 57-bits of virtual address space. Great anyhow the continued punctual upstreaming of UV patches to the mainline Linux kernel

Fedora 34 Aims To Further Enhance Security But Will Lose Runtime Disabling Of SELinux

At present on Fedora, those wanting to forego the security safeguards can either pass selinux=0 as the kernel command line option to disable the support at boot time or by
