Function fetch

crates/virtual-machine/src/cpu/pipeline/fetch.rs:36–45

Backwards-compatible wrapper: old callers without PMP info should use this. Uses a throwaway TLB, so it never benefits from caching (test/diagnostic use).

(
    bus: &mut SystemBus,
    pc: u64,
    satp: u64,
    priv_mode: PrivilegeMode,
    mstatus: u64,
)

    mstatus: u64,
) -> Result<u32, VmError> {
    let mut tlb = mmu::Tlb::new();
    let ctx = mmu::TranslationContext::without_pmp(satp, priv_mode, mstatus);
    fetch_with_pmp(bus, pc, ctx, &mut tlb)
}
