Struct StorageLayout 

pub struct StorageLayout {
    pub submission_entries: usize,
    pub submission_tail: usize,
    pub completion_entries: usize,
    pub completion_head: usize,
    pub completion_tail: usize,
    pub submission_mask: u32,
    pub completion_mask: u32,
    pub host_payload: u64,
}

Returned native ring offsets. GPU addresses are obtained from StorageRing::memory. host_payload is a CPU virtual address for Linux fixed-buffer I/O, never a GPU VA.

Fields

submission_entries: usize

Offset of the native 64-byte SQE array.

submission_tail: usize

Offset of the 32-bit SQ publisher tail.

completion_entries: usize

Offset of the native 16-byte CQE array.

completion_head: usize

Offset of the 32-bit CQ consumer head.

completion_tail: usize

Offset of the 32-bit CQ producer tail.

submission_mask: u32

Native SQ entry mask.

completion_mask: u32

Native CQ entry mask.

host_payload: u64

CPU address of fixed buffer zero.
