Struct PrewarmList 

pub struct PrewarmList {
    pub pages: Vec<u64>,
}

Pre-warm list — a small set of guest IPAs the pager faults in before vCPU 0 runs so the first guest cycles are not all blocking on the pager (16 § 5.2).

Fields

pages: Vec<u64>

One page IPA per entry. The pager faults each in order on registration.

Implementations

impl PrewarmList

pub fn from_boot_critical( kernel_text_ipa: u64, vcpu0_stack_ipa: u64, fdt_ipa: u64, ) -> Self

Build a list from kernel _text/_stext neighbourhood, vCPU 0 stack, and FDT.

Each input is a guest-physical address; we add it as a single page entry. The pager pads the address to its tracking page granule on prewarm.
