Fields

device_tree_size: usize

Total size of the parsed device tree, in bytes.

memory: ArrayVec<MemoryEntry, 1024>

Parsed sorted memory ranges from the device tree.

boot_cpuid_phys: u32

Boot cpu physical id. On X64, this is the APIC id of the BSP.

cpus: ArrayVec<CpuEntry, 2048>

Information for enabled cpus.

vmbus_vtl0: Option<VmbusInfo>

VMBUS info for VTL0.

vmbus_vtl2: Option<VmbusInfo>

VMBUS info for VTL2.

command_line: ArrayString<8192>

Command line contained in the /chosen node. FUTURE: return more information from the chosen node.

com3_serial: bool

Is a com3 device present

memory_allocation_mode: MemoryAllocationMode

The vtl2 memory allocation mode OpenHCL should use for memory.

entropy: Option<ArrayVec<u8, 256>>

Entropy from the host to be used by the OpenHCL kernel

device_dma_page_count: Option<u64>

The number of pages the host has provided as a hint for device dma.

This is used to allocate a persistent VTL2 pool on non-isolated guests, to allow devices to stay alive during a servicing operation.

nvme_keepalive: bool

Indicates that Host does support NVMe keep-alive.

vtl0_alias_map: Option<u64>

The physical address of the VTL0 alias mapping, if one is configured.

gic: Option<GicInfo>

GIC information, on AArch64.

pmu_gsiv: Option<u32>

PMU GSIV, if available, on AArch64.
