Struct WritableRegister 

pub struct WritableRegister {
    pub offset: u64,
    pub width: u32,
    pub allow_mask: u32,
    pub allow_rmw: bool,
    pub require_precondition: bool,
    pub precondition_mask: u32,
    pub readback: bool,
}

Target ceiling specification for one writable register.

Writes are denied unless the immutable target ceiling contains an exact writable-register entry (Spec 9.4). A host/session grant cannot invent a write entry.

Fields

offset: u64

Byte offset from the start of the logical resource.

width: u32

Access width in bytes (must be 4 for V1).

allow_mask: u32

Bitmask of writable bits permitted by policy.

allow_rmw: bool

Whether read-modify-write is permitted for partial mask writes.

require_precondition: bool

Whether a precondition is required for any write to this register.

precondition_mask: u32

Bitmask of valid precondition bits.

readback: bool

Whether readback is configured/supported.
