[PATCH v2 3/9] KVM: selftests: nx_huge_pages_test: Add TDP detection for Zhaoxin CPUs

[Ewan Hai-oc]

From: Frank Zhu <frankzhu@xxxxxxxxxxx>

Update the kvm_is_tdp_enabled() function to include Zhaoxin CPUs
when checking for EPT (Extended Page Tables) support. This ensures
that Zhaoxin CPUs use the appropriate TDP (Two-Dimensional Paging)
parameter check, similar to Intel CPUs.

The change modifies the condition to check for both Intel and Zhaoxin
CPUs before querying the EPT parameter, maintaining compatibility
with existing Intel systems while extending support to Zhaoxin CPU
systems.
