pub struct IpcMemoryMapper {
    request_tx: Tube,
    response_rx: Tube,
    endpoint_id: u32,
}

Sends an addr translation request to another process using Tube, and gets the translated addr from another Tube

Fields

Implementations

impl IpcMemoryMapper

pub fn new(request_tx: Tube, response_rx: Tube, endpoint_id: u32) -> Self

Arguments

• request_tx - A tube to send TranslateRequest to another process.
• response_rx - A tube to receive Option<Vec<MemRegion>>
• endpoint_id - For the remote iommu to identify the device/ipc mapper.
