The only complaint is that I didn't address the pre-existing issue that a malicious/broken hypervisor might provide invalid return values from some CPUID invocations which could lead to divide-by-zero faults. I don't intend to address this. Virtualization of RDT would require a great deal more support from the hypervisor that just getting this CPUID enumeration right. -Tony [1] https://sashiko.dev/#/patchset/20260819161323.11587-1-tony.luck%40intel.com
