### Added
- On x86:
+ - On all Intel systems, MSR_ARCH_CAPS is now visible in guests, and
+ controllable from the VM's config file. For CPUs from ~2019 onwards,
+ this allows guest kernels to see details about hardware fixes for
+ speculative mitigations. (Backported as XSA-435 to older releases).
- xl/libxl can customize SMBIOS strings for HVM guests.
- Support for enforcing system-wide operation in Data Operand Independent
Timing Mode.
- Add Intel Hardware P-States (HWP) cpufreq driver.
+ - Support for features new in AMD Genoa CPUs:
+ - CPUID_USER_DIS (CPUID Faulting) used by Xen to control PV guest's view
+ of CPUID data.
- Support for features new in Intel Sapphire Rapids CPUs:
- PKS (Protection Key Supervisor) available to HVM/PVH guests.
- VM-Notify used by Xen to mitigate certain micro-architectural pipeline
