AMD Ryzen 9 3900XT CPUFreq Governor Comparison With Linux 5.9

One of the most frequent questions received at Phoronix in recent times is whether the "schedutil" governor is ready for widespread use and if it can compare in performance to, well, the "performance" governor on AMD Linux systems. Here are some benchmarks of an AMD Ryzen 9 3900XT using the latest Linux 5.9 development kernel in looking at the performance differences between the CPUFreq governor options of Ondemand, Powersave, Performance, and Schedutil.

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

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.
