Module blkdev_scheme 

Block-device scheme — exposes raw disk devices under /dev.

Namespace layout

/dev/          — directory listing (this scheme root)
/dev/sda       — first SATA disk (AHCI port 0), raw byte-addressable

I/O model

The AHCI driver operates on 512-byte sectors. This scheme accepts arbitrary byte offsets and lengths and performs the necessary sector-aligned read/modify/write internally using a stack-allocated 512-byte bounce buffer.

VFS wiring

BlkDevScheme implements the kernel Scheme trait so it can be mounted with vfs::mount::mount("/dev", Arc::new(BlkDevScheme)) during vfs::init().

Structs

BlkDevScheme

Kernel scheme that serves raw block devices as files under /dev.
