For confidential computing "CoCo" virtual machines where the VM host is assumed to be un-trusted and aims to be as isolated as possible, RdRand hardware random number generator instructions are one of the limited sources of entropy for guest VMs. Right now RdRand can fail and the CoCo guest VMs will continue to boot albeit with limited or no entropy to see the VM's random number generation. But being merged today as part of x86 fixes for Linux 6.9 is now requiring seeding RNG with RdRand for CoCo environments otherwise a kernel panic...

Earlier this week Wine developer Gabriel Ivncescu with CodeWeavers laid out a great proposal: leveraging AI for assisting with the code review process for more punctual review and upstreaming of patches into the Wine codebase for this software that allows Windows games and apps to run on Linux and other platforms. While great in theory, at this stage just amounted to an April Fools' gag for Wine...

Last week being surprised to see a number of AMD EPYC performance gains with Linux 6.9 using that in-development kernel, I was curious about what other platforms may be benefiting from better performance on this kernel that will debut as stable in May. This week I turned to running some fresh benchmarks of Intel Xeon Max using the Supermicro Hyper SuperServer SYS-221H-TNR. More than 230 benchmarks were carried out of Linux 6.8 stable versus Linux 6.9-rc2 in looking for any performance differences.
