Enum CoherencyDomain 

#[repr(u32)]
pub enum CoherencyDomain {
    Cpu = 0,
    Ram = 1,
    Inaccessible = 2,
    UnknownOrdinal_(u32),
}

INACCESSIBLE is only for cases where there is no CPU access to the buffers.

Device-local memory that isn’t reachable from the CPU is CoherencyDomain INACCESSIBLE, even if it’s possible to cause a device (physical or virtual) to copy the data from the INACCESSIBLE buffers to buffers that are visible to the CPU. In other words, INACCESSIBLE does not imply secure, but secure implies INACCESSIBLE.

CPU means producers must ensure that a consumer can read the produced data with the CPU without the consumer needing to do additional cache ops not already performed (as needed) by the producer.

RAM means producers must ensure that the produced data is entirely present in RAM, without any dirty CPU cache lines, and a consumer must invalidate (or flush and invalidate, typically) the CPU cache before reading data with the CPU. The RAM domain can be faster than the CPU domain when all access is via HW DMA, since in that case no CPU cache ops are required, since no participant is actually reading/writing using the CPU.
