Linux 5.19 Makes It Much Easier To Clear CPUID Features
The Linux x86/x86_64 kernel has long honored the "clearcpuid=" kernel parameter to disable select CPUID features from being used by the kernel or readily advertised. However, it hasn't been very intuitive to use since it relied on passing the bit numbers for the specific features. With Linux 5.19 it's much easier to deal with in now allowing the CPUID string from /proc/cpuinfo to be passed if wanting particular CPUID features disabled...

Intel SGX Enclaves Were Prone To Crashes On Linux Under Heavy Memory Pressure
Intel's Software Guard Extensions (SGX) as security-related extensions to their processors that allow for protected memory enclaves has had a rather bouncy journey. Intel continues supporting SGX on their latest Xeon processors but on the client side have been deprecated since 11th Gen Core. Over the years SGX has been found vulnerable to various attacks from speculative execution exploits to Plundervolt. It also turns out under Linux until now was also open to crashing under memory pressure...

Linux 5.19 To "Make Life Miserable" In Slowing Down Bad Behaving Split-Lock Apps
Back in 2020 Intel engineers working on the Linux kernel added split lock detection to provide a warning when an atomic operation spans multiple cache lines and requires a global bus lock for atomicity. A warning is now deemed not useful enough so instead the intent moving forward is to "make life miserable" for such misbehaving user-space applications by slowing down the performance with hopes of the app developers better handling their code...
