Information about the guest partition.

Fields

vtl2_ram: ArrayVec<MemoryEntry, MAX_VTL2_RAM_RANGES>

Ram assigned to VTL2. This is either parsed from the host via IGVM parameters, allocated dynamically, or the fixed at build value.

This vec is guaranteed to be sorted, and non-overlapping.

partition_ram: ArrayVec<MemoryEntry, MAX_PARTITION_RAM_RANGES>

The full memory map provided by the host.

isolation: IsolationType

The partiton’s isolation type.

bsp_reg: u32

The reg field in device tree for the BSP. This is either the apic_id on x64, or mpidr on aarch64.

cpus: ArrayVec<CpuEntry, MAX_CPU_COUNT>

Cpu info for enabled cpus.

vmbus_vtl2: VmbusInfo

VMBUS info for VTL2.

vmbus_vtl0: VmbusInfo

VMBUS info for VTL0.

cmdline: ArrayString<COMMAND_LINE_SIZE>

Command line to be used for the underhill kernel.

com3_serial_available: bool

Com3 serial device is available

memory_allocation_mode: MemoryAllocationMode

Memory allocation mode that was performed.

entropy: Option<ArrayVec<u8, MAX_ENTROPY_SIZE>>

Entropy from the host to be used by the OpenHCL kernel

vtl0_alias_map: Option<u64>

The VTL0 alias map physical address.

nvme_keepalive: bool

Host is compatible with DMA preservation / NVMe keep-alive.

boot_options: BootCommandLineOptions

Parsed boot command line options.

gic: Option<GicInfo>

GIC information on AArch64.

pmu_gsiv: Option<u32>

PMU GSIV on AArch64.
