Interface to an AHCI device.

It can:

• get the number of addressable 512-octet sectors on this disk,
• read a range of consecutive sectors.
• write a range of consecutive sectors.

Required methods

fn sector_count(&mut self, manager: WorkQueue<'static>) -> Result<u64, Error>

Retrieves the number of addressable 512-octet sectors on this disk.

fn read_dma(
    &mut self,
    manager: WorkQueue<'static>,
    address: u64,
    unknown_1: &mut [Block]
) -> Result<(), Error>

Reads sectors from the disk.

This IPC call will invoke the AHCI driver and make it copy sector_count sectors from the disk to the memory pointed to by the output buffer.

Error

• address..address+sector_count should be in the range 0..IDisk.sector_count().

fn write_dma(
    &mut self,
    manager: WorkQueue<'static>,
    address: u64,
    blocks: &[Block]
) -> Result<(), Error>

Writes sectors to the disk.

This IPC call will invoke the AHCI driver and make it copy sector_count sectors to the disk from the memory pointed to by the input buffer.

Error

• address..address+sector_count should be in the range 0..IDisk.sector_count().
