Struct ParsedBootDtInfo

pub struct ParsedBootDtInfo {
    pub cpus: Vec<Cpu>,
    pub vtl0_alias_map: Option<u64>,
    pub vtl2_memory: Vec<MemoryRangeWithNode>,
    pub partition_memory_map: Vec<AddressRange>,

    pub private_pool_ranges: Vec<MemoryRangeWithNode>,
}

Information parsed from the device tree provided by openhcl_boot. These values are trusted, as it’s expected that openhcl_boot has already validated the host provided device tree.

Fields

cpus: Vec<Cpu>

The cpus in the system. The index in the vector is also the mshv VP index.

vtl0_alias_map: Option<u64>

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

vtl2_memory: Vec<MemoryRangeWithNode>

The memory ranges for VTL2 that were reported to the kernel. This is sorted in ascending order.

partition_memory_map: Vec<AddressRange>

The unified memory map for the partition, from the bootloader. Sorted in ascending order. Note that this includes mmio gaps as well.

vtl0_mmio: Vec<MemoryRange>

The mmio to report to VTL0.

config_ranges: Vec<MemoryRange>

The ranges config regions are stored at.

vtl2_reserved_range: MemoryRange

The VTL2 reserved range.

accepted_ranges: Vec<MemoryRange>

The ranges that were accepted at load time by the host on behalf of the guest.

gic: Option<GicInfo>

GIC information

memory_allocation_mode: MemoryAllocationMode

The memory allocation mode the bootloader decided to use.

isolation: IsolationType

The isolation type of the partition.

private_pool_ranges: Vec<MemoryRangeWithNode>

VTL2 range for private pool memory.

Implementations

impl ParsedBootDtInfo

pub fn new() -> Result<Self>

Read parameters passed via device tree by openhcl_boot, at /sys/firmware/fdt.

The device tree is expected to be well formed from the bootloader, so any errors here are not expected.

Trait Implementations

impl Debug for ParsedBootDtInfo

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Inspect for ParsedBootDtInfo

fn inspect(&self, req: Request<'_>)

Inspects the object.

impl PartialEq for ParsedBootDtInfo

fn eq(&self, other: &ParsedBootDtInfo) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
