PCIe BAR request struct.

Created By

• LeechCore PCIe BAR callback.

Fields

bar: LcBar

The PCIe BAR which this request is for.

tag: u8

PCIe TLP packet tag.

be_first: u8

first byte-enable.

be_last: u8

last byte-enable.

is_64bit: bool

is a 64-bit request.

is_read: bool

is a read request.

is_write: bool

is a write request.

data_size: u32

data size in bytes.

data_offset: u64

data byte offset within the BAR.

data_write: Option<Vec<u8>>

data to write (if a write request).

Implementations

impl LcBarRequest

pub fn read_reply(&self, data_reply: &[u8]) -> ResultEx<()>

Send a valid read reply to the BAR request.

The read reply must be of the exact length of the BAR read request.

Arguments

• data_reply - The data to send as a reply.

pub fn read_reply_fail(&self) -> ResultEx<()>

Send an invalid read reply to the BAR request indicating that the read failed. An Unsupported Request TLP will be sent to the host system in reponse to the failed read.

This function should normally not be called.
