Expand description

Partition capabilities, used to determine which state is active on a partition and what the reset state should be.

Fields§

§vendor: Vendor

The processor vendor.

§hv1: bool

The MS hypervisor is available.

§hv1_reference_tsc_page: bool

The reference TSC page is available.

§xsave: XsaveCapabilities

Xsave information.

§x2apic: bool

X2apic is supported.

§x2apic_enabled: bool

X2apic is enabled at boot.

§reset_rdx: u64

The initial value for rdx.

§cet: bool

CET is supported.

§cet_ss: bool

CET-SS is supported.

§sgx: bool

SGX is enabled.

§tsc_aux: bool

TSC_AUX is supported

§vtom: Option<u64>

The address of the virtual top of memory, for encrypted VMs.

This is computed from the Hyper-V isolation leaf. It is guaranteed to be a power of 2, if present.

§can_freeze_time: bool

The hypervisor can freeze time across state manipulation.

§xsaves_state_bv_broken: bool

The hypervisor has a broken implementation querying xsave state, where supervisor states are not correctly set in xstate_bv.

§dr6_tsx_broken: bool

The hypervisor has a broken implementation setting dr6, where bit 16 is forced on even if the processor supports TSX.

§nxe_forced_on: bool

EFER.NXE is forced on. This is set for TDX 1.5 partitions, which require this.
